FOOD AND BEVERAGE PRODUCTION THEORY
KITCHEN ORGANIZATION
Specific objectives.
By the end of this topic, the trainee should be able to;
Factors to consider when chosing a location for a kitchen premises.
1.The size and the extent of the menu it serves.
Before a kitchen is planned, the management must know its goals and objectives in relation to the market strategy. The menu will then determine the type of equipment you will require in order to produce the products that you know from the market research that the customer is going to buy. You also need to know the target numbers that you intend to service.
2.Services
The designer must know where the services are ;ocated and how efficient use can be made of them.
3.Labor and skilled level
What kind of people does the company intend to employ? If semi-skilled labour is going to be used in preference to highly skilled labour, this will save on more technological equipment, more food will be used and this will have an effect on the overall kitchen design.
4.Amount of capital expenditure
Most designs have to work with a detailed capital budget. Often it is always possible to design, then worry about the cost afterwards. Finance will often define the location of a premise.
5.Types of equipment available
The size, amount and size of the equipment will depend on the type of the menu being provided the equipments must be suitably sited.
The trend towards provision of more attractive eating places, carried to its utmost perhaps by the chain and franchise operators. One trend has been that of bringing the kitchen area totally/partially into view.
7.Multi-usage requirements
Round the clock requirements have forced kitchen planners to consider design and location of the premises.
KITCHEN LAYOUT
1.COMMERCIAL KITCHEN LAYOUT
A well designed commercial kitchen is integral to efficient, safe and profitable food preparation.
Components of a commercial kitchen
a)Storage.
This component of the kitchen receives all foods for proper storage and dispatches them for use appropriately.
b)Food preparation.
This component is split into a section for processing raw foods and a section for sorting into batches.
c)Meal cooking.
This component is where all cooking of food takes place and should be nearthe front of the kitchen next to the service area.
d)Cleaning/washing.
This section of the kitchen should be located near the kitchen entrance so that the servers can quickly drop off dirty dishes and near the kitchen areas so chefs can quickly find clean dishes.
e)Service.
This is where servers will pick up finished dishes to take to customers.
Factors to consider when planning the layout of a commercial kitchen
Common layouts preferred by commercial kitchens are;
II.RESIDENTIAL KITCHEN LAYOUT.
It is more of a footprint of your home kitchen. There are three types of kitchen layouts;
WORK FLOW
Food preparation rooms should be planned to allow a ‘work flow’ whereby food is processed through the premises from the point of delivery to the point of sale or service with minimum obstruction.
The various processes should be separated as far as possible and food intended for sale should not cross paths with waste food or refuse.
Staff time is valuable and and a design that reduces wasteful journeys is both efficient and cost effective.
The overall sequence of receiving,storing,preparing,holding,serving and clearing is achieved by:-
a)Minimum movement.
b)Minimum back-tracking.
c)Maximum use of space.
d)Maximum use of equipment with minimum expenditure of time and effort.
LEGISLATION GOVERNING THE CONSTRUCTION OF A FOOD CATERING PREMISES.
Design and construction of the kitchen must comply with the Hygiene and Food safety Act 1990/91. The basic layout and construction should enable adequate space to be provided in all food handling and associated areas for equipment as well as working practices and frequent cleaning to be carried out.
WORK SPACE.
Approximately 4.2m2 is required per person,too little space can cause staff to work in close proximity to burners,steamers,cutting blades,mixers etc thus causing accidents.
A space of 1.37 m from the equipment is desirable and aisles must be of adequate size to enable staff to move safely.The working area must be suitably lit and ventilated with extractor fans to remove heat,fumes and smells.
LIGHTING CONSIDERATIONS.
Lighting is a very important component of the overall dinning room design.The amount of light required is dictated by the area and the activity that occurs there.
General lighting is designed to perform and function for booth day and night time activity.it must achieve a perfect balance.
VENTILATION SYSTEMS.
There are three basic types of ventilation system.They include:-
1.Extract:-This system only removes air thereby creating a negative pressure in the space.Outside air will come into the space wherever it can usually through door ways,window areas or specifically prepared openings.
2.Inlet:-This system is concerned only with the supply of outside air but it is not a suitable system for a catering kitchen but may prove useful in areas such as storage rooms.
3.Combined:-This balances the flow of air into and out of the space.
All these systems use mechanical means of moving air ie.electrically driven fans.
The ideal system,although more expensive is the combined system where the extract and supply of air can be controlled.
2.0 TOOLS & EQUIPMENT
Specific Objectives
By the end of this sub-module unit, the trainee should be able to:
There are five basic types of kitchen knives:
Sharpening Knives
A knife that is not sharp is dangerous. It can slip off the food you’re cutting and easily cut your fingers instead. Steel should be part of your knife collection. This long, round object sharpens knives by straightening out the edge. Take a look at using a steel to see how to correctly sharpen your knives on steel. Hold the knife in your dominant hand and the steel in the other, with the steel point pressed into a solid waist-high surface. Hold the knife base at the top of the steel at a 20 degree angle. Slowly draw the knife down the length of the steel, pulling the knife back so the entire blade, from base to tip, moves against the steel, as if you were slicing off pieces of the steel. Repeat on the other side. Do this five or six time, then rinse the knife off and dry immediately. Make sure you sharpen each side the same number of times to retain the knife’s balance.

Task 3: The use, care and maintenance of kitchen equipment
Trainees should explain and practice the use care and maintenance of different kitchen equipment in relation to type.
EVALUATIONS
3.0KITCHEN STAFF
Specific objectives
Factors that determine the the structure and size of the kitchen brigade.
The three most common kitchen brigade sizes include the following;
SMALL KITCHEN BRIGADE
|
HEAD COOK |
COOK |
COMMIS ( TRAINEE/APPRENTICE |
MEDIUM KITCHEN BRIDGADE
|
CHEF |
CHEF DE PARTIE |
Commercial kitchens range from tiny, mom-and-pop restaurants to the high-volume production environments of convention centers and institutions. Yet whatever the kitchen’s sizes, the individual tasks involved in producing meals are consistent and so are the duties and responsibilities of the kitchen staff. There is a formal, traditional staffing structure, but it’s no longer common in modern kitchens.
Legendary chef Auguste Escoffier laid out the classical brigade structure in the late 19th century. At the top is the executive chef, who determines the overall direction and focus of the kitchen. Next are one or more sous-chefs, responsible for the day-to-day operation of the kitchen. A range of chefs de partie, or station cooks, are responsible for specific types of food. These included the saucier for sauces, the poissonier for fish dishes, the potager for soups and the garde-manger for turning leftovers into new dishes. The patisserie, or pastry chef, prepared desserts and baked goods. A variety of apprentices and helpers rounded out the standard kitchen’s staff.
Modern kitchens show less specialization, but the fundamental roles are the same. At the top is the executive chef, who is primarily a manger. If the chef owns multiple restaurants, each restaurant will typically have its own chef de cuisine managing the kitchen under the executive chef’s direction. Large operations might have an executive sous-chef to ease the executive chef’s workload. Under these top managers, are the sous-chefs. A large hotel might have several sous-chefs, or a small restaurant might have only a lead cook, but the role is the same as in a classical brigade. In many establishments the pastry chef runs a semi-autonomous kitchen in collaboration with the executive chef.
In modern restaurant kitchens the roles of individual cooks aren’t as clearly defined, and except in large hotels or institutions there aren’t as many single-purpose work stations. Most cooking tasks are performed by line cooks, with more skilled and experienced cooks handling the most demanding jobs. Larger kitchens often designate a first cook or lead cook for that role, and first cooks will often supervise the kitchen in the sous-chef’s absence. Less-experienced cooks begin by assisting at high-volume stations within the kitchen, or working independently in a less-demanding, lower-volume station.
Large kitchens, and some smaller ones, employ prep chefs to perform basic duties such as peeling, cutting and portioning raw ingredients, or making stock and sauces. This frees up more experienced cooks for more skilled labor. Prep cooks are sometimes called cooks’ assistants, and help by continuously stocking a busy station during service. Apprentices are cooks in formal training programs, learning through a combination of on-the-job and classroom instruction. They’re typically given opportunity to learn all positions in the kitchen, beginning with prep work and then moving onto the line. The dishwasher also plays a role in the kitchen, speeding needed utensils back into service and occasionally helping out with food preparation.
4.0 HYGIENE
Specific Objectives
By the end of this sub-module unit, the trainee should be able to:
2.1 PERSONAL HYGIENE REQUIREMENTS
Good grooming
-double breast chefs jacket
-chefs cap
-apron long enough to protect the legs
-checked cotton trousers /skirts
-neck tie
2.2 FOOD HYGIENE REQUIREMENTS
2.4 THE HACCP CONCEPT
HACCP (hazard analysis critical control point) enables evaluation of the operation.
It locates possible points of contamination, determines the severity of the hazard and takes preventive measures to protect against food borne illness outbreak
The HACCP is an assessment of all the hazards associated with each step of a catering organization. Staff needs to know the hazard, the degree of risk involved and those they apply the controls which have been introduced to reduce and eliminate the risk.
2.5 TYPES OF WASTE AND ITS DISPOSAL
DISPOSING WASTES
Water from the kitchen is normally channelled to the main sewer.
Wastes that can be recycled include:-
Leftover foods are used to feed pigs, cows, dogs and other domestic animals.
LEGISLATION IN FOOD HYGIENE AND SAFETY
The preparation and sale of food is controlled by the food hygiene regulation (general) 1970. The regulations are applicable to any staff involved in handling food and cleaners of equipment in food rooms. The responsibility for implementing this regulation is carried by environmental health officers who regularly visit food businesses to monitor standards and offer advice. Failure to comply with the regulations may lead to fines or imprisonment but legal action is used only if advice has persistently been ignored.
The general food hygiene regulations (1970) include:
Premises
Facilities
The following must be provided for:
Equipment should be:

5.0 SAFETY IN THE KITCHEN
The key to preventing kitchen accidents are careful kitchen management and safe work habits.
Falls, electrical shock, cuts, burns and poisoning are all kitchen hazards.
Stay Calm and never hesitate to call for help.
General Safety Guidelines
Falls:
Keep floors clean and free of clutter. Wipe up spills, spatters and peelings.
Eliminate other hazards, slippery throw rugs and damaged or worn flooring. Tie shoes, avoid long clothes, floppy slippers.
Use a firm stepstool or ladder instead of a chair. Use a bib-skid backing on rugs.
First aid for falls
Don’t move a person with broken bones unless necessary. Call medical help if head aches, dizziness, vomiting, or speech
Impairment results from head injury.
Mild bruises/sprains need ice bag or cold water/cloths and elevation.
Cuts:
Keep knives sharp and use properly.
Use a drawer divider or knife rack for sharp cutting tools.
Don’t try to catch a falling knife.
Don’t soak knives in sink or dishpan or water.
Sweep up broken glass from the floor using broom and dustpan.
Use wet paper towel instead of bare fingers.
First aid for cuts
Stop severe bleeding with the pressure of a thick cloth; get medical
help.
Minor cuts – wash with soap and water, blot dry and bandage.
Consumer product safety commission estimates over 137,000 people receive hospital treatment for injuries from kitchen knives each year.
Electrical Safety:
Appliances save both time and work in the kitchen. But, they are a source of shock, burns and other injuries.
Read owner’s manual.
Water and electricity don’t mix – cords
Avoid damage to electrical cords – tugging on cord, stapling, or burn them.
Use outlets properly – overloading polarized plugs 9one blade wider than
Other)
Use care with any plugged in appliance. Watch for problems.
First aid for electrical shock
Don’t touch person connected to electricity.
Turn off power, pull plug or pull person away with cloth loop. Administer CPR if qualified and call medical help.
Hazardous Chemicals:
Cause burns, breathing difficulties and poisoning. Read labels.
Never transfer hazardous products to another container.
Never mix different chemical products.
Never mix compounds such as bleach/ammonia.
Use charcoal/hibachi outside ONLY – gives off carbon monoxide. Follow antidote directions in well ventilated area if poisoning occurs.
First aid for Poisons
Call medical help and if possible use antidote on label. If fumes, get person to well ventilated area.
Flush eyes with water if irritated.
Fires:
Every kitchen should have a fire extinguisher.
Turn off heat, cover pan or pour salt or baking soda on flames.
Never use water – grease will spatter and burn.
Never attempt to carry a pan with burning contents – Fire Dept. – go outside.
In case of fire:
Turn off appliance.
Use baking soda instead of water. Use a fire extinguisher.
If clothing catches on fire, drop to the ground and roll. STOP.
DROP. ROLL.
Crawl on the ground to get out of smoke filled room.
First aid for Burns
Cool it with cold water/prolonged ice will freeze tissue.
Avoid ointments, grease and oil (contributes to the cooking process of the burn).
Choking:
Heimlich maneuver
CPR – If person has stopped breathing and heartbeat have stopped.
First aid for Choking
If person can speak, cough or breathe, do nothing.
Do the Heimlich Maneuver procedure.
LPG or liquefied petroleum gas is the generic name for commercial propane and butane composed fuel used in the kitchen to fuel gas burners. This gas is supplied in industrial cylinders or in bulk storage tanks at the hotel premises. It is supplied to the hotel kitchen through pipelines.
The LPG cylinders are stored in a separate place, usually known as. ‘Gas bank’ and are usually operated by a department in the hotel called ‘kitchen stewarding’. Amount of gas cylinders used in the gas bank depends on the types of operations they are used for.
A large hotel may have more than 100 cylinders. Half of these would be installed to supply gas whereas half would always be a backup. A certain gas pressure is maintained by the stewarding department as certain ranges require high pressure for cooking. LPG is liquefied under pressure and converts into gas when the pressure is released.
ADVERTISEMENTS:
It is almost smokeless and easy to handle. LPG should be handled with utmost care as being a transparent gas its leakage is not easily detectable and it is also highly combustible.
There are certain government regulations regarding the usage of LPG. For example, LPG cannot be used in basement kitchens or below the sea level and hence, in those kinds of conditions one has to rely on electricity or steam- operated equipment.
Usage:
It is one of the most essential fuels used in the hotel kitchen and is known for its efficiency. It is used as a fuel for cooking ranges, ovens, and salamanders. Some tandoors used in Indian cooking are also fired by LPG.
Compressed natural gas is slowly gaining popularity for its fuel efficiency and environment-friendly properties.
ADVERTISEMENTS:
Usage:
It is used in eco-friendly hotels as fuel in many types of equipment such as ovens, gas ranges, etc.
Though it is a very crude form of fuel to be used in a modern kitchen, it is still very popular. The smoky flavour which the charcoal imparts is much desired. Coal should always be stored away from food area, ideally in a cool, dark room away from any moisture. Usually separate areas are built near the receiving area for coal storage as coal is combustible and messy.
ADVERTISEMENTS:
Usage:
Coal is used in a hotel kitchen to light tandoor and grills for barbecue. The coal used in the hotels is wood charcoal only.
One would have come across wood-fired pizza ovens in the modern restaurants today. Gaining popularity of pizzas has led to the origin of this oven which lends an aesthetic appearance to the restaurant, where chefs prepare pizzas in front of the guests. Though it is also operated by LPG, few logs of wood are placed inside to impart a smoky flavour to the pizzas.
ADVERTISEMENTS:
Usage:
It is used as a fuel for wood-fired pizza ovens. The pizza ovens have LPG fire but wood is also kept inside to impart a smoky flavour to the food.
Electricity is also used as fuel to operate many types of equipment. Care should be taken while ordering such equipment as many countries operate on certain volts. In India equipment works on 220 volts, whereas in the USA equipment works on 110 volts. So care should be taken while importing equipment.
Some of the heavy duty equipment use three-phase electric current and some use only single phase. So it is important that the instructions are read before installing the new machinery.
Usage:
Electricity is generally used to operate most of the equipment in the hotel kitchen. It is popular in the hotel kitchens because it is easy to control electrical equipment.
Most of the hotels produce steam, which is used to cook or operate equipment. Steam is supplied to the hotel kitchen through insulated pipes.
Usage:
Steam is used in equipment such as dishwashers and steam jacket kettles.
This fuel is made from petroleum jelly and comes in small tins. These are mostly used in F&B service areas.
Usage:
This type of fuel is hardly used in hotel kitchens but is very commonly used in F&B service, where it is used in heating up food in the chafing dishes used commonly in banquets.
The heat from the sun is used as a fuel. This is not a very commonly used fuel in the kitchens, but many eco- friendly hotels have solar cookers that are used in cooking.
Usage:
Solar cookers utilize solar energy to cook food.
These three different types of plain water are defined by their intrinsic characteristics: origin, consistency, composition, protection and treatment.
The Codex Alimentarius defines these categories for packaged water suitable for human consumption.
Natural mineral water is defined as water that is:
obtained directly from underground sources protected from pollution risks
characterised by its content of certain mineral salts and their relative proportions
guarantees constancy of its composition and the stability of its flow collected under conditions which guarantee the original microbiological purity and chemical composition
packaged close to the point of emergence of the source
cannot be subjected to any treatment (except for limited ones such as carbonation, iron or manganese removal)
may claim medicinal effects
Natural mineral water accounts for the majority of our bottled water sales in Europe, where consumers demand “pure”, “untouched” water.
Natural mineral water also constitutes a significant share of our local brands in emerging markets.
Waters defined by origin – often called “spring water” – are water that:
come from a specific underground (or sometimes surface) source
have not passed through a community water system
are protected within set vulnerability perimeters to avoid pollution and contamination
are consistently fit for human consumption at the source and kept in that state until bottled
are not subject to any modification or treatment other than those permitted by this standard
Water defined by origin is the leading product type for our United States local brands, as well as the majority of our local brands outside Europe.
Prepared waters may:
originate from any type of water supply (including municipal water)
be subjected to any treatment that modifies the original water in order to comply with chemical, microbiological and radiological safety requirements for pre-packaged water
Prepared water is the standard for emerging countries where purity of water means above all, safety. Depending on local legislation, the label would identify the water as “purified water” or “drinking water”.

INTRODUCTION TO FOODSERVICE SYSTEMS
A foodservice director has many options for food production and service. Most foodservice directors inherit a foodservice system, but may make modifications to that system or select and build a new system. For example, in today’s environment it is very difficult to find adequate labor, which is forcing school foodservice directors to consider alternatives in food production. Also, there is a great concern about food safety, including Hazard Analysis Critical Control Point (HACCP) program implementation, and quality control that might be improved in centralized food production. If a change is to be made in the system, it is important to know what alternatives are available.
In this chapter, information will be presented about:
Unique Characteristics of Foodservice
There are some characteristics of foodservice that make it unique compared to production of other products. This uniqueness influences decisions that are made about production and service. Some of these characteristics include:
Demand for food occurs at peak times, around breakfast, lunch, and dinner meals. Between these peak demand times, there are valleys or slow times. Demand for food may vary depending on time of year and competitive events, and production must be modified accordingly.
Foodservice Systems
A Guide to Centralized Foodservice Systems
Food production and service are labor intensive. Both skilled and unskilled labor is needed. Food is perishable, requiring it to be handled properly before, during, and after preparation. Menus change on a daily basis, thus, production changes daily.
These characteristics create challenges in scheduling employees and production, difficulty in staffing, and high labor and food costs. Conventional foodservice systems exhibit these characteristics. Foodservice directors look for ways to reduce or eliminate the impact of these characteristics—and alternative foodservice systems offer solutions. For example, commissary foodservice systems centralize the production process and allow for economies of scale, reducing the costs of food production. Ready-prepared foodservice systems separate production and service in that food is prepared and stored either frozen or chilled for later rethermalization and service. This removes the peaks and valleys of production that occur when production is planned around service. Thus, this is a more cost-effective foodservice system than the conventional system. Foodservice systems may be combined to meet the unique needs of a district school foodservice operation.
Flow of Food
It is important to understand the flow of food through a foodservice system in order to determine the system that will best meet your needs and to develop an effective HACCP program. Food flows through ten possible processes:
Storing
Receiving
Purchasing
Cooking
Menu Planning
Holding
Serving
Preparing
Cooling
Reheating
Foodservice Systems
A Guide to Centralized Foodservice Systems
As we talk more about the four types of foodservice systems, you will find that all of these processes do not apply to all of the systems. Also, when food production is centralized, a transporting process needs to be added. With a centralized foodservice system, there will be different processes (and critical control points) for the central food production facility and the receiving kitchens (satellites). In the chapter on food safety, there will be a more in-depth discussion about the critical controls that need to be in place during each process in the food flow.
Form of Food Purchased
Another concept that is important to the understanding of foodservice systems is the form in which the food is purchased. Following is a diagram of the food processing continuum:
This diagram depicts the continuum of food processing that might be done prior to purchasing. For example, if food were purchased at the “none” end of the continuum, the ingredients for a product would be purchased. If food were purchased at the complete end, the food product would be ready to heat or serve (perhaps requiring no preparation or only rethermalization).
Here is an example that you might find in school foodservice. Let’s take Italian bread. We could make many different decisions about where on the food processing continuum to purchase Italian bread. We could purchase all of the ingredients (yeast, flour, sugar, shortening, and salt) and make our own bread from scratch. In this case, the food is purchased with no prior processing (none end of the food processing continuum). We could purchase frozen bread dough, proof it, and bake it. In this case, we are purchasing items somewhere in the mid-range of the food processing continuum. Purchasing from the complete end of the continuum, we could purchase Italian bread already baked and all we do is serve. There are many examples in school foodservice of similar choices for how much processing will be done in the foodservice operation and how much will be done prior to purchasing the product.
Centralized Foodservice Systems
Purchasing decisions differ depending on the type of foodservice system that is in place. For example, with centralized food production, food is more likely to be purchased from the left end of the continuum—with little or no processing. The processing or food preparation will be done in the central kitchen. This often represents a substantial food cost savings—one of the goals for centralized production. Food costs and labor costs usually are inversely related—as one goes up the other one goes down. If the quantities of food produced are very high, as in the case of a large central kitchen, productivity (usually measured as meals per labor hour) will increase, making labor costs more reasonable. In the assembly-serve foodservice system food is purchased at the complete end of the food processing continuum. That means food costs are high; but less labor is required, so labor costs decrease. We will talk more about how food is purchased as the various types of foodservice systems are discussed.
Types of Foodservice Systems
Four types of foodservice systems are described in the literature: conventional, commissary, ready-prepared, and assembly-serve (Unklesbay et al., 1977). There are numerous examples of each of these systems in operation, both in school foodservice and in other segments of the foodservice industry; and there are many variations of them, too! A description of these systems will be useful if you are considering making changes in your operation.
Conventional Foodservice System
The conventional foodservice system is most common, although that is changing due to the current operating environment. In conventional foodservice systems, ingredients are assembled and food is produced onsite, held either heated or chilled, and served to customers. For this foodservice system, food is purchased all along the food processing continuum. For example, some items may be purchased from the none end and require full preparation. Other items may be purchased with some processing, while others may be purchased fully prepared, only requiring portioning and service.
Foodservice Systems
FOOD PRODUCTION
Conventional foodservice systems are used extensively in schools, restaurants, colleges and universities, and cafeterias. Because of the current labor shortage, many of these conventional foodservice systems are using more and more food products from the complete end of the food processing continuum.
Advantages of Conventional Foodservice Systems
There are several advantages to conventional foodservice systems:
Disadvantages of Conventional Foodservice Systems
There also are several disadvantages of conventional foodservice systems:
Centralized (Commissary) Foodservice System
The commissary food service system (also known as central kitchen, central food production, or food factory) centralizes food production, and food is transported to satellites (receiving kitchens) where it is served to customers. Food usually is purchased near the none end of the food processing continuum, and food preparation is done in the central kitchen, which results in lower food costs. Labor costs also are lower because of the centralization of food preparation. This food service system takes advantage of economies of scale, so it is most effective when mass food production is required.
One unique characteristic of the centralized foodservice system is that food is transported to external locations (satellites or receiving kitchens) for service. Two factors will need to be considered about the food that is transported: temperature and packaging. Food can be transported either hot or cold, which impacts the delivery and the equipment needs in the receiving kitchens and in transportation. The food can be sent to the receiving kitchens bulk or pre-plated, which impacts the equipment and labor needed at the receiving kitchen. In addition, food production and delivery schedules must be coordinated.
Centralized (or commissary) foodservice systems are used in many types of foodservice operations. Perhaps the application of centralized foodservice systems that is most easily visualized is in the airline industry. There is a central production facility on or near the airport property where the food is prepared, pre-plated, sealed, and either chilled or frozen. The pre-plated meals are placed in closed carts, and the trays with the cold items are assembled and placed in closed carts. These carts are transported by truck to the airplane (satellite), where the food is placed in the galley. The plates requiring rethermalization are placed in convection ovens by the caterer. Once the airplane is airborne, the stewards assemble and distribute meals. Assembly usually only consists of placing the passengers’ choice of hot entrée on the tray that contains all of the cold items. Once the airplane lands at its destination, the caterer sends a truck to the airplane to get the used carts, trays, and dishes and returns them to the central food production facility for washing and sanitizing. At the same time, the airplane is supplied with the meals required for the next flight.
Many restaurant corporations centralize food production, too. Williams Sonoma, located in San Francisco, operates three Bay Cafes. They produce the gourmet sandwiches, salads, soups, and baked goods at the original restaurant and transport them to the other two restaurants.
There are many examples of centralized foodservice systems in schools, and the numbers have expanded dramatically in the past 20 years. Many of the large school districts located in urban areas use central production, including school districts in cities such as San Bernardino, California; Louisville, Kentucky; Boston, Massachusetts; Minneapolis, Minnesota; St. Paul, Minnesota; Columbus, Ohio; Cleveland, Ohio; Dayton, Ohio; Portland, Oregon; Philadelphia, Pennsylvania; and Pittsburgh, Pennsylvania. There are many more urban school districts using centralized foodservice systems. They also are being used in medium-sized school districts, such as Elko, Nevada and Corvallis, Oregon.
Advantages of Centralized Foodservice Systems
There are many advantages of centralized foodservice systems:
Fully-equipped kitchens are not needed in each school, saving equipment costs—thus, when schools are aging and equipment needs to be replaced, a central food production facility eliminates the need for some equipment at the receiving kitchen. This also is very advantageous for school districts in which growth is rapid. When building new schools, full production kitchens are not needed, which results in space savings and lower building costs.
Disadvantages of Centralized Foodservice Systems
There are several possible disadvantages to centralized foodservice systems:
The ready-prepared foodservice system has been in use for many years. In readyprepared foodservice systems, food is produced onsite, held chilled or frozen, reheated, and served to customers on site. Food production can be scheduled at any time, since food is prepared and stored frozen or chilled for later rethermalization and service. This system also allows multiple-day production to be done at one time. For example, if chili is on the menu two times in the next 30 days, the total amount of chili can be made at one time, which reduces labor costs. For this foodservice system, food is purchased all along the food processing continuum. For example, some items may be purchased from the none end, and require full preparation. Soups, entrees, casseroles, and sauces would likely be fully prepared on site from ingredients purchased at the none end of the food processing continuum. Other items may be purchased with some processing, while others may be purchased fully prepared, only requiring portioning and service.
Advantages of Ready-Prepared Foodservice Systems
There are several advantages of ready-prepared foodservice systems. Some of the main advantages include:
Disadvantages of Ready-Prepared Foodservice Systems
There are several possible disadvantages of ready-prepared foodservice systems:
The assembly-serve foodservice system traditionally has been the least common, although that is changing due to the current operating environment. In today’s environment labor is scarce and expensive. Also, there are many choices in foods that can be purchased that only require heating and serving. In assembly-serve foodservice systems, food is purchased at the middle to complete end of the food processing continuum. The purchased food is stored either frozen or chilled for later use. It is then portioned, reheated, and served to customers.
Advantages of Assembly-Serve Foodservice Systems
There are several advantages of assembly-serve foodservice systems. The main advantages include:
Disadvantages of Assembly-Serve Foodservice Systems
There are several possible disadvantages of assembly-serve foodservice systems:
Combination Systems
Often, foodservice operations in school districts have characteristics of more than one of the foodservice systems. For example, school districts that have central production facilities may prepare some items in the central kitchen and some food items in the receiving (satellite) kitchens. This often is done to ensure the highest quality for a food item that is popular with students.
Another example of combination systems within a district is when a central kitchen is used to prepare meals for the elementary schools and conventional kitchens are used to prepare meals for middle and high schools. This often is a more cost-effective method for serving large numbers of meals while still meeting the needs of the students.
In yet another example, some districts will centralize one function such as a bakery. All baking will be done in a central site and the baked products distributed to schools throughout the district. Other production would be done in the individual schools.
There are many ways that these systems can be combined to increase the efficiency of an operation and meet the unique needs of a school district. The factors that will influence these decisions will be discussed in later chapters.
MENU PLANNING.
The english dictionary defines menu as the ‘bill of fare’ It is a list of dishes available in an outlet with an indication of their price. Menu can be alternatively defined as a systematic compilation of F & B arranged in a proper sequence to be served to a guest who is willing to pay for it. Hence, a menu is a took by which a catering establishments informs its customer about what food it has to offer.
The exact origin of menu is difficult to trace. It is clear however that in the days of monarch of ancient europe, a menu was presented at the table. Formal F&B service had its beginnings at banquets hosted by kings in honour of visiting dignitaries. The banquets had an extensive choice of food served in two main sections. The first section consisting of 25 to 45 dishes served to guest on the table. A single large table around which the guests would be seated. This course was called ‘entree’ as it was served before the entry of the guests. After these dishes were finished, they were cleared by the waiters and a next set of 20-40 dishes came to releve them. Hence, these dishes were called ‘relevée’. Some monarchs listed these dishes on a large board as a programme of food on offer. This was around 16th century is considered the earliest evidence of the origin of menu as we know it today.
As time went by the menu became smaller and more copies of menu were made available to the guests. The end of 1800’s and the early 1900’s saw Escoffier bring in havoc changes like recipe, standardization, menu compilation, portion control and discovery of some of today’s most popular dishes.
Menu is one the most important tools for an F&B organisation. Planning of menut depends on the following:
1. Class of restaurant.
2. Type of menu- fixed or individually priced.
3. Capablity of the kitchen staff.
4. The physical infrastructure for cooking and serving.
5. Language of the menu.
6. Type of clientele.
7. Seasonality and availability of raw materials.
8. Pricing of the menu.
Of there some of the points which require a detailed look include:
1. Type of clientele:
which depends on-
> religion and culture
> average spending power
> age group
> occupation
> nutritional and emotional requirement of clients.
2. Infrastructue and skills: these include-
> ability of chefs to consistently prepare menu items
> availabity of equipments to prepare dishes
> storage capacity to hold raw materials, semi-finished and finished foods
> ability of the waiting staff to serve properly.
3. Language of the menu: these include-
> menu should be written in a single language only
> language used should be simple
> spelling and sequence should be correct
> explanation of fish in one or two line under each fish should be provided
> in tablé dé hôte menu, the colour of dishes, cooking methods, garnishing and seasoning should not repeat.
Food science – menu planning
INTRODUCTION
In the past few decades, people ate in restaurants occasionally to celebrate a special event such as an anniversary, a birthday, or an achievement. It was an outing to look forward to, and if one indulged, it did not matter as these outings were rare.
Today, the scenario is different. Eating out has become a way of life. Education and employment has taken many of us away from home, and the mother’s role now has an added responsibility of contributing to the family income. Modern day compulsions have made eating out a necessity. No longer does one find time for the traditional fare of yesteryears and depends on the caterer for the following:
1. Food for festivals and celebrations
2. Meals at the work place
3. Ready-to-eat meals picked up on the way home from work
4. Snacks and sweetmeats for daily consumption
5. Preserves, pickles, papads, etc.
6. All meals served in institutions such as hospitals, school/college cafeteria, mess or dining hall, and boarding schools.
The number of reported cases of diabetes, hypertension, obesity, heart attacks, etc. is on the rise and so is the number of meals consumed away from home. This is not surprising because if one indulges practically everyday, it is bound to result in ill-health because of malnutrition. The caterer’s role has become more significant as the responsibility now lies with the caterer for planning nutritionally adequate meals. Menu planning is the key to overcoming this problem.
DEFINITION
Menu planning is defined as a simple process which involves application of the knowledge of food, nutrients, food habits, and likes and dislikes to plan wholesome and attractive meals.
The caterer who is responsible for providing meals has to decide on various aspects such as:
1. Menu
2. Serving size
3. Food cost
4. Suppliers and quantities to be purchased
5. Standardized recipes to be followed
6. Type of service
7. Meal timings
8. Clientele
The aim of menu planning is to:
1. Meet the nutritional needs of the individuals who will be consuming the food
2. Plan meals within the food cost
3. Simplify purchase, preparation, and storage of meals
4. Provide attractive, appetizing meals with no monotony
5. Save time and money
6. Minimize overhead expenditure, i.e., fuel, electricity, water, labour.
Menu planning is the most important aspect of planning and organization in the food industry. It is an advance plan of a dietary pattern over a given period of time.
Menus are of the following types:
Table d’hôte or fixed price menu It includes two or three courses at a set price. Each course may offer a choice of dishes.
A la carte On this menu, dishes are individually priced and the customers can compile their own menu which may be one, two or more courses.
Banquet menus These are special menus for banquets or functions.
Institutional menus Hospital menus, boarding school menus, and Industrial canteen menus.
Menu may be cyclic which means they are compiled to cover a specified period of time. The length of the cycle may vary and is decided upon by the management. A number of menus are set up and repeated. They are often modified to take into account variations, which may arise for a number of reasons.
FACTORS INFLUENCING MEAL PLANNING
Many factors influence the acceptability of a meal. Customers select what appeals most to them from a menu card based on individual likes and dislikes, budget, popularity of items, etc. However, while planning meals the following factors need to be considered.
Nutritional Adequacy
The most important consideration in menu planning is to ensure that the meal fulfils the nutrient needs of the individual consuming the meal. For example, if the meal is planned for an Indus trial worker, it must meet the RDAs for that age group. Foods from all basic food groups should be included in each meal so that the meal is balanced and nutritionally adequate. Nutrient needs may be modified for hospital diets (therapeutic diets).
Economic Considerations
The spending power of the clientele has to be kept in mind and meals have to be planned within the budget. Low cost nutritious substitutes should be included in the menu to keep the costs low. The food cost should be maintained, if the organization has to run profitably.
Food Service
Menus should be planned in relation to the type of food service, whether it is cafeteria, seated service, buffet, etc.
Equipment and Work Space
The menu should be planned keeping the available equipment and workspace in mind. Deep freezers, refrigerators, grinders, dough kneaders, deep fat fryers, boilers, etc. should be adequate.
Leftover Food
An effective manager should consider as to how leftovers could be rotated to obtain maximum profit. Adequate storage space and hygienic standards should be ensured to minimize the risk of contamination and spoilage of food.
Food Habits
Food habits of the customer is another important criteria which needs to be considered as food served has to be acceptable to the customer. Special attention should be paid when a particular type of community is catered to. Religious considerations should be known to the meal planner.
Availability
Some fruits and vegetables are seasonal. During the season the cost is reasonable and quality is better. Today, practically all fruits and vegetables are available throughout the year because of advanced preservation technology. However, seasonal fruits and vegetables should be given preference. Regional availability influences menu planning. For example, fish and sea food is fresh and cheaper in coastal areas.
Meal Frequency and Pattern
The meal timings and number of meals consumed in a day, whether meals are packed or served at the table, also influences the selection of food items on the menu. The age, activity level, physiological state, work schedule, and economic factors need to be known before planning meals for institutional catering.
Variety
This is one of the most important considerations while planning meals. A variety of foods from the different food groups should be included. The term variety means
1. Variety in food ingredients
2. Variety in recipe
3. Method of cooking
4. Colour, texture and flavour
5. Variety in presentation and garnish.
A meal should look attractive and be appetizing. A judicious blend of flavours, attractive colour combinations and different textures make food enjoyable and interesting. The method of cooking used for different items on the menu should vary.
For example, two deep fried items would make the meal heavy. Simple processes such as fermentation and sprouting not only contribute to improved flavour and digestibility, but also enhance the nutritive value of the meal.
A well planned meal which is nutritionally adequate would have a good satiety value and prevent the occurrence of hunger-pangs before it is time for the next meal. The nutritional adequacy of a meal in an a la carte service depends on the food choices made by the customer. It is the duty of the caterer to offer adequate, nutrient dense foods to the clients, to choose from.
PLANNING BALANCED MEALS
Meal planning involves proper selection of food to ensure balanced meals. In Chapter 20 on balanced diets we have studied how food is classified into five basic food groups to help us plan balanced diets. We have also read that food can be classified on the basis of its source, the nutrients present in it, or on the basis of its functions into 3 – 11 groups. These food groups help us in planning balanced meals which supply all essential nutrients. In this chapter we will study the three basic food groups classified on the basis of functions performed by nutrients as this is the simplest way to ensure adequate nourishment to the body.
The three main functions performed by food are:
1. Providing energy
2. Body building and maintenance
3. Regulation of body processes and protection against infection.
On the basis of functions performed, food is classified into the following three groups.
1. Protective/regulatory foods
2. Body building foods
3. Energy giving foods
Protective/Regulatory Foods
All fruits and vegetables – green leafy and other vegetables and all fruits are included.
Green leafy vegetables, Rich in carotene and
Orange, yellow and red ascorbic acid. Also
Fruits and vegetables, contain minerals, fibre,
Citrus fruits. And carbohydrates.
Body Building Foods
Foods rich in protein are included in this group. Nuts and oilseeds also provide fats.
All animal proteins Protein, vitamin and mineral
Pulses, nuts and oilseeds Protein, vitamin, mineral,
fibre,oils.
Energy Giving Foods
This group provides mainly carbohydrates and fats, along with proteins, some vitamins and minerals, and essential fatty acids. Foods included in this group are :
1. Cereals and millets, Carbohydrate rich roots and tubers. with other nutrients.
2. Sugars and jaggery Only carbohydrates.
3. Fats and oils Mainly fats.
While planning meals one should ensure that foods from all three groups is included in each meal. This classification is simple and easy to use for menu planning.
STEPS IN PLANNING BALANCED MEALS
1. Collect information regarding the customer with respect to
• Age
• Gender
• Activity level
• Religion
• Socio-economic background
• Food habits
2. Check the RDAs for energy and proteins
3. Prepare a food plan, i.e., list number of servings from each food group to meet the RDA.
4. Decide on number of meals.
5. Distribute servings for each meal.
6. Select foods within each group and state their amount.
7. Plan a menu.
8. Cross check to ensure that all food groups are included in requisite amounts.
Using the above steps, plan a balanced diet for a day.
Example : planning balanced meals for college students residing in a hostel.
1. Basic information
Age : 16 – 18 years
Gender : Male
Activity : Moderate
Religion : Hindu
Background : Urban, middle income families
Food habits : Cosmopolitan
2. Recommended Dietary Allowance for

EFFECT OF QUANTITY COOKING AND PROCESSING ON NUTRIENTS
Almost all foods consumed today need some form of cooking and processing before it is fit for service and consumption. Fruits and vegetables used in salads or for chutney are consumed uncooked. The nutrients we receive from the meals we consume depend to a large extent on cooking and processing practices which are being used. While some amount of nutrient loss is inevitable, cooking has many benefits which are listed below.
Benefits of Cooking Food
1. Cooking increases palatability
2. Cooking makes food easier to digest by destroying anti-digestive factors such as trypsin inhibitor in soya beans.
3. Pathogenic micro-organisms are destroyed.
4. Shelf life is increased by destruction of spoilage organisms and denaturation of enzymes.
5. The appearance of food improves, e.g., cooked meat versus raw meat.
Common Food Processing Techniques
1. Removal of unwanted outer layers, e.g., potato peels, inedible shells and scales of fish, and pea pods, and removal of inedible seeds, stones, etc.
2. Cutting, slicing, micing, grinding, or reducing the size of vegetables, fruits, meat, etc.
3. Liquefaction and emulsification, milling and blending.
4. Heat treatment – blanching, cooking by various methods such as boiling, frying and roasting.
5. Incorporation of air – beating, whipping, aeration of soft drinks.
6. Extrusion.
7. Dehydration, freeze drying, deep freezing, etc.
8. Fermentation.
Food prepared in large quantity in institutional kitchens or in food processing plants is more prone to loss of nutrients, if adequate care is not taken to retain or preserve the nutrient. This is because if food is cooked in bulk, the pre-preparation begins hours in advance, e.g., vegetables have to be cut in advance and if these are not blanched and refrigerated to inactivate enzymes, oxidative losses of labile vitamins will continue at room temperature. Apart from nutritive value, the crisp texture of salads is also lost and phenol containing vegetables will discolour and turn brown, making the dish unattractive and unappetizing.
Effect of heat on nutrients
Cooking has beneficial effects on carbohydrates because of gelatinization of starch, favorable browning reactions such as Maillard reaction and caramelization of sugar which gives colour and flavour to food.
Proteins too take part in Maillard reaction along with sugar. Enzymes which catalyse undesirable enzymatic reactions in fruits such as apple and pears, and vegetables such as potato and brinjal are inactivated on blanching or cooking these foods. Enzymes which hasten oxidative destruction of vitamin C or ascorbic acid are denatured by blanching. Proteins get denatured by heat.
The chemical reactions that take place when oil is heated continuously during deep fat frying bring about hydrolysis, oxidation and polymerization of the oil.
The moisture from the foods being fried hydrolyse fat into free fatty acids, mono and diglycerides and glycerol.
The release of moisture, high frying temperatures of 160-190degrees C, presence of carbonized crumbs in the oil and oxygen from the atmosphere during frying brings about oxidation of the oil. Repeated use of the frying medium forms thermal and vitamins. These products undergo polymerization and increase the viscocity of the oil. The oil darkens in color, has a lower smoke point and foams when used for frying. Such oil should be discarded. Fat soluble vitamins dissolve in fat used for deep frying specially if the food to be fried is not well coated.
Effect of alkali
Alkali is used during cooking and processing to soften vegetables, make pectin soluble, and dissolve hemicelluloses. It is also used as lye(sodium hydroxide) to peel vegetables during processing. A pinch of sodium bicarbonate added to green vegetables helps in brightening the green colour. However, B-complex vitamins and ascorbic acid are destroyed in an alkaline medium. The use of alkali to hasten the cooking process for vegetables and pulses should be discouraged. Excessive cooking in an alkaline medium not only destroys vitamins but makes the texture mushy and gives a soapy taste to the product.
Effect of acid
An acidic medium while cooking helps preserve water soluble vitamins and retards enzymatic browning of certain fruits and vegetables. Vegetables and pulses take a longer time to cook in an acidic medium as acids precipitate pectin and hardens vegetables.
Effect of washing and soaking
While preparing food, water soluble vitamins and minerals leach out into the cooking or washing water. These losses can be minimized by washing the uncut fruit or vegetables and not soaking the cut vegetables in water.
Soaking grains and pulses in water is beneficial as soaking increases digestibility and reduces cooking time.
Effect of sprouting and fermentation
Soaking whole grains overnight in water and tying them in a muslin cloth to allow them to germinate has many beneficial effects.
1. In sprouted grains, the dormant seed becomes active and synthesizes vitamin C.
2. Partial breakdown of carbohydrates, proteins and fats begins making it easier to digest.
3. The bio-availability of nutrients especially calcium and iron increases.
4. The active seeds synthesize vitamin C and thiamine, riboflavin and niacin content increases.
Exposure to air or oxidation
Exposure of finely divided foods to oxygen of the air reduces the vitamin C content by oxidation. The enzyme ascorbic acid oxidase is released when fruits and vegetables are cut. The enzyme activity is temperature dependent and can be inactivated by blanching or by storing cut fruits and vegetables at refrigeration temperatures or by adding acid.
Vitamin A is destroyed on exposure to air. The colour of cut carrots
(carotene) fades due to oxidation and B-complex vitamins are also affected.
Milling
Whole meal flour contains all nutrients present in the grain. In flour with 100% extraction no nutrients are lost. Low extraction flours (45% extraction) are light in color and are mainly starch with some protein and fat. Approximately 70% of all B-complex vitamins, minerals and dietary fibre present in the whole grain are lost during milling.
Polished rice(the form in which rice is consumed) loses 75% vitaminB1 or thiamine, while parboiling helps in retaining some of the vitamin.
Cooking and processing practices vary widely from one region to another, hence no authentic information on exact losses can be known. While cooking has both adverse and beneficial effects, proper practices can minimize the adverse effects and maximize the benefits so that food can become more wholesome and safe.

The release of moisture, high frying temperatures of 160˚C – 190˚C, presence of carbonized crumbs in the oil and oxygen from the atmosphere during frying brings about oxidation of the oil. Repeated use of the frying medium forms thermal and vitamins. These products undergo polymerization and increase the viscosity of the oil. The oil darkens in colour, has alower smoke point, and foams when used for frying. Such oil should be discarded. Fat soluble vitamins dissolve in fat used for deep frying specially if food to be fried is not well coated.
Effect of alkali
Alkali is used during cooking and processing to soften vegetables, make pectin soluble, and dissolve hemicellulose. It is also used as lye (sodium hydroxide) which is a caustic alkaline chemical to peel vegetables during processing. A pinch of sodium bicarbonate added to green vegetables helps in brightening the green colour. However, B-complex vitamins and ascorbic acid are destroyed in an alkaline medium.
Balanced Diet
INTRODUCTION
Nutrients are needed by humans in specific amounts to ensure good health and well-being. These nutrient needs are met by eating the right kinds and amounts of food, if a diet is planned and given to an individual with the correct kinds and proportions of different nutrients, and he is asked to follow it everyday, it will become monotonous. Also a diet which is acceptable to one individual may not be acceptable to another individual for many different reasons such as food preferences, customs, food habits, age, economic reasons, and allergies.
RECOMMENDED DIETARY ALLOWANCES
While planning balanced diets, we need certain guidelines regarding the kinds and amounts of nutrients that require for maintenance of good health. The RDA is the guideline stating he amount of nutrients to be actually consumed in order to meet the requirements of the body. The RDA is based on requirements.
The requirement for a particular nutrient is the minimum level that needs to be consumed to perform specific functions in the body and to prevent deficiency symptoms. It should also maintain satisfactory stores of the nutrients in the body.
Recommended dietary allowances are based on a person’s requirements for different nutrient. In other words
Recommended Dietary Allowances = Requirement + Margin of safety
The margin of safety is added to take care of factors such as:
1. Losses during cooking and processing
2. Short periods of deficient intake
3. Nature of the diet
4. Individual variations in requirements.
For example the requirement of iron in western countries is 10 mg for adult men and 15 mg for adult women respectively, while Indian RDAs suggest an intake of 28 mg for adult men and 30 mg for adult women. This is because the form of iron consumed varies and the factors interfering with absorption of iron such as phytates in cereals and larger proportions of nonhaeme iron present in Indian diets. The requirement for vitamin C or ascorbic acid is actually 20 mg, but since the vitamin is easily destroyed during pre-preparation, cooking, and storage. The recommended intake is twice the requirement and is 40 mg/day.
The RDAs apply to healthy individuals and are set high enough to cover individual variation. They are based on gender, age, body size, activity level, and special physiological state. Disease and drugs prescribed for treatment for one or more nutrients.
RDAs for Specific Nutrients
The RDAs are expressed in metric units such as kilocalorie (kCal), grams (g), milligrams (mg), and micrograms (µg).
How much food each individual will need will depend on many factors which have been considered while computing the Recommended Dietary allowances. Factors such as age, gender, and special physiological needs have been kept in mind. The RDA table gives us the quantity of different nutrients to be included in our daily diet. The second important factor we need to know to know to ensure the right selection of food is its nutritive value. Most foods contain more than a single nutrient. The nutritive value of different foods have been analysed in the laboratory and on the basis of this information , food consumption tables have been formulated.
This tables give us the percentage of important nutrients in the edible portion of all foods we consume, we can calculate its nutritive value with the help of food consumption tables. This can be compared with the RDAs which will tell us wether our diet is nutritionally adequate or not. The RDA is a goal to be achived and food is selected so that we reach the goal.
However, this process is time consuming and not at all practical as lengthy calculations are necessary. What is needed is a practical guide which can help individuals to select foods of their choice according to their choice according to their nutritional requirements. Since no single food provides all the nutrients in desirable amount, and all foods differ in their nutrient content, it becomes necessary to divide food into groups to help us consume a balanced diet.
Balanced Diet A balanced diet is one which includes a variety of foods in adequate amounts and correct proportions to meet the day’s requirements of all essential nutrients such as proteins, carbohydrates, fat, vitamins, minerals, water and fibre. Such a diet helps to promote and preserve good health and also provides a safety margin or reserve of nutrients to withstand short durations of emergency.
The safety margin takes care of the days on which we fast, or on a certain day all nutrients may not be consumed. If the balanced diet meets the RDA for an individual;, then the safety margin is already included as the RDA is formulated keeping extra allowances in mind.
A balanced diet takes care of the following aspects:
1. It includes a variety of food items
2. It meets the RDA for all nutrients
3. Nutrients are included in correct proportions
4. Provides a safety margin for nutrients
5. It promotes and preserves good health
6. Maintains acceptable body weight for height
BASIC FOOD GROUPS
One of the simplest ways to plan a balanced diet is to divide foods into groups. Foods are grouped on the basis of the predominant nutrients present in them. They may be classified into three, four, five, seven or eleven food groups. This classification varies from one country to another depending on many factors. For example, in India we do not have milk products or flesh foods as a separate food group because of religion, economic reasons, etc. The five food group classification is used in India as a guide to meal planning. Many factors have been considered while compiling these groups such as availability of food, cost, meal pattern, and deficiency diseases prevalent. Not all foods in each group are equal in their nutrient content. That is why a variety of foods from each group should be included in the diet.
A food group consists of a number of foods which have common characteristics. These common features may be the source of food, the physiological function performed, or the nutrients present.
On the basis of the source of food, at least fourteen groups can be identified, e.g. cereals, pulses, milk and milk products, egg, flesh foods, nujts and oilseeds, sugar and sweetness, fats and oils, root vegetables, other vegetables, green leafy vegetables, fruits, condiments and spices, and miscellaneous foods. This does not simplify the planning of balanced meals. A classification based on nutrients present will ensure that all nutrients made available to the body and offer greater variety within the group.
GUIDELINES FOR USING THE BASIC FOOD GROUP
1. Include at least one or a minimum number of servings from each food group in each meal.
2. Make choices within each group as foods within each group are similar but not identical in nutritive value.
3. If the meal is vegetarian proteins with suitable combinations to improve the overall protein quality of the diet. For example, serving cereal, pulse combinations or including small quantities of milk or curds in the meal.
4. Include uncooked vegetables and fruits in the meals.
5. Include at least one serving of milk to ensure a supply of calcium and other nutrients as milk contains all nutrients except iron, vitamin C, and fibre.
6. Cereals should not supply more than 75% of total calories.
The food guide pyramid is an educational tool that shows the dietry guidelines in the easily understand graphic format. It was originally prepared by the Human Nutrition Information Service and published in 1992 by the U.S. Department of Agriculture. It is meant for use by the general healthy population s a guide for the amounts and types of foods to be included in the daily diet. The pyramid was designed to help teach the concepts of variety, moderation and the inclusion of food types in appropriate proportion in the total diet. The food guide pyramid can be modified for different age groups. Food guide pyramid helps to reduce the risk of chronic diseases and meets the RDA of different nutrients.
FOOD EXCHANGE LIST The food exchange lists are used in meal planning to make a quick and fairly accurate estimation of the nutritive value of diets. These are used to calculate the energy, carbohydrates, fats and proteins content of the meals. The exchange lists were first published by a joint committee of the American Dietetics Association, American Dietetics Association and the U.S. Public Health Services in 1950 and were revised in 1976.
In the making of exchange list, similar foods are grouped together so that specified amounts of all foods listed in that group or exchange, have approximately the same energy, carbohydrates, proteins, and fats content. The nutritive value of specific foods in the exchange may slightly differ from the average value for that food exchange, but on variety of food selected in the daily diet, these differences tend to get cancelled. So any, one food in a particular list can be exchanged for any other food of the same list.
So, an exchange list allows one to make a wider choice in selecting foods within every exchange, while controlling the total energy and fats in the total diet.

THE PREPARATION METHODS FOR FOOD COMMODITIES
COOKING METHODS OF FOOD ITEMS
Cooking methods fall under 2 main categories
This is cooking food completely covered with water, heated to boiling point (100°c) and then left to simmer in a cooking pot with a well fitting lid. The method is suitable for foods like meats, arrow roots, yams, potatoes, maize and beans.
This is cooking food in a small measured amount of liquid that is allowed to simmer.
It is a long slow method of cooking tough hard foods e.g. beef, poultry, vegetables. It is also used for soft foods such as fruits. The aim is to give food enough time to soften and to retain nutrients and flavour.
This is cooking food using steam for steam from boiling water. The steam does not come into direct contact with the food; it comes into contact with the container holding the food. It is a suitable method for cooking fish fillet and cake mixture pudding, spinach.
The methods of steaming include:-
Plate Method procedure
Food in the covered plate is placed over a boiling cooking pan root tubers like yams, arrow roots, potatoes can be cooked in the pan at the same time to economize fuel.
It is similar to boiling but the temperature is kept below 100°c
There are three methods of frying
Shallow-fat frying
Deep-fat frying
Food is cooked in hot oil which completely covers the food. A deep fat fryer or a strong deep pan, a frying basket and a draining spoon are required for the process. It is a suitable method for cooking potato chips, mandazi and samosas
Dry-fat frying
This is cooking food in its own fat in a shallow pan or cooking in a lightly greased pan. The fat or oil used to cook comes from the food being cooked. It is used for cooking bacon and cuts of pork.
In this method of cooking hot dry air is used. It is usually done in an oven.
It is suitable for foods that have enough moisture such as potatoes and flour mixture for cakes, scones and bread.
It is a process of cooking food over a fire such as glowing charcoal. It is suitable for cooking maize, sweet potatoes, yams, arrow roots and fish.
Another way of roasting is cooking food in a heated oven or while it is rotating on a spit. In both cases fat is used to boost the food. It is a suitable method for cooking meat
Foods cooked by grilling are placed over or under the direct heat source and re cooked by radiation. If the food is fairly thick, then only the surface is cooked by radiation and further cooking takes place by condition.
(d) Microwave cooking
Food cooked by conventional methods use heat transfer by convection, conduction and radiation but microwave ovens operates by a different mechanism.

MENU PLANNING
INTRODUCTION
There are many factors to be taken into account when planning a menu and it can be a lengthy task, especially for those tackling it for the first time. However a well planned menu can attract new customers, increase the average spend, increase your sales and keep you one step ahead of the competition. Here you will find useful tips and advice to help, including how to meet Trading Standards requirements, create descriptions that will sell a dish and how to produce professional printed menus.
Basic Menu Planning Principles
The basic menu planning principles listed below and discussed in the following pages are a
good starting point. Keep them in mind as you think about your children’s preferences and
nutrition needs.
The five basic menu planning principles are…
1) Strive for balance
As you work to plan meals that are nourishing, appealing, and taste good, you will want
to strive for balance in a number of ways. As you select and combine foods:
Make sure individual foods, when served together, make a winning combination.
Too many mild flavors make a meal too bland.
Too many strongly flavored foods make a meal unacceptable to children. For
Example, a lunch or supper menu with sausage pizza, Cajun potatoes, coleslaw,
brownie, and milk has too many strong and spicy flavors
Avoid having too many higher fat foods in the same week. In other words, do not
Include sausage pizza in a week’s menu if you are already planning to serve hot
dogs and fried chicken.
Look for ways to use low fat side dishes to balance a higher fat entrée. For example,
with a grilled cheese sandwich, serve carrot and celery sticks.
Serving a variety of foods is important because no one food or group of foods can give
us everything we need for a healthy diet. Variety also makes menus interesting and
appealing. To add variety:
form of food on consecutive days, such as meatballs with spaghetti on Monday and
homemade meat ravioli on Tuesday.
day, soup and sandwiches the next, or perhaps a main dish-salad.
For instance, some vegetables are good eaten raw. If you usually serve a particular
vegetable cooked; serve it uncooked if it is good that way. Or cook it but use a
different recipe or seasoning. In any case, be sure the “different way” of serving is
as appealing as the “usual way.”
periodically. For example, try adding cauliflower, red cabbage, or spinach to a
salad.
Strive for contrasts of texture, flavor, and methods of preparation.
For added appeal, serve a green salad or raw vegetable with spaghetti. Serve a
crisp fruit or vegetable with a burrito, and crisp steamed carrots and broccoli with
meatloaf. Pair toasted garlic bread and cold broccoli salad with homemade cheese
ravioli.
with too many starches or too many sweets lacks contrast as well as balance. So
does a meal with too many heavy foods. If you are serving a hearty casserole, plan
to serve a vegetable or fresh fruit.
bits and strips. A meal with cubed meat, diced potatoes, mixed vegetables, and
fruit cocktail needs more contrast in size and shape foods.
4) Think about color.
Use combinations of colors that go together well, and strive for contrast and maximum
color presentation. A good rule of thumb is to use at least two colorful foods in each
menu for visual appeal.
with turkey, rice, cauliflower, white bread, pears, and milk would lack color contrast.
A better combination would be turkey and cranberry sauce, green peas, whole-wheat
bread, orange slices, and milk.
side dishes as well as entrées. A slice of tomato really brightens up a potato
salad. A fresh sliced grape or strawberry livens up a dish of diced pears or peaches.
Serve broccoli spears with whipped potatoes, for example. Add pimento or green
pepper to corn. Serve a bright red apple and green lettuce with a hamburger,
baked beans, and milk. Serve green peas, apricots with oven fried chicken, mashed
potatoes, and milk.
fruit or a little paprika on vegetables and potatoes for added color.
Your children’s first impression will be how a meal looks. Make sure what you serve
looks good as well as tastes good.
As you plan for color, consider the color of the dishes, plates, or trays to be used as
well as the colors of the foods.
how the food will look when served and decide on the most attractive arrangement.
Family-Style Meal Service
Family-style meal service means serving foods in bowls or dishes on the table. Children
are encouraged to serve themselves, or serve themselves with help from an adult.
Enough food must be placed on the table to provide the full required portion size for all
the children at the table.
Family-style meal service has some advantages…
foods, new tastes, and new menus. Children are often unsure about new
foods. Seeing new foods and watching others serve themselves gets them
interested. They are more willing to try a small serving when they see other
children trying new foods.
When foods are served family-style, children may choose to take a small portion of
food, knowing that the food will still be available if they would like a second serving.
Children feel more in control to judge their hunger and fullness throughout the
meal, knowing that more food is within easy reach.
fingers. Serving themselves gives children time to practice skills like passing,
pouring , and scooping foods. Taking turns, sharing, and politely turning down
foods are all part of the table manners children learn by participating in family-style
meal service.

week to week.
Steps to Successful Menu Planning
In this section, we will look closely at the following steps:
Plan menus well in advance, preferably a month or more ahead of the time they
are to be served. You will want to:
Review previous menus and any other food service records that indicate the children’s
preferences.
Involve children, parents, and other interested parties in the planning.
Select and test food products and recipes.
To be prepared, you will want to pull together a variety of menu resources. These
might include, for example, past successful l menus or recipe files. Check at your local library
for additional resources.
For easy reference, have on hand copies of food production and inventory
records. Also have available publications such as USDA’s Food Buying Guide for Child
Nutrition Programs and Child Care Recipes: Food for Health and Fun.
NUTRITIONAL CONSIDERATIONS
6.0 FOOD PRESENTATION AND GARNISH
6.1 INTRODUCTION
Food presentation is the art of modifying, processing, arranging, or decorating food to enhance its aesthetic appeal.
6.2 FUNDAMENTALS OF PLATING
ESSENTIALS OF FOOD PRESENTATION
If vegetables are improperly cut during presentation will look improper.
If meat is badly trimmed before cooking, a fancy plating design won’t correct it.
Serving attractive food is largely a matter of being neat and careful and using common sense. This is an aspect of the professionalism.
Apart from being neat, effective food presentation depends on developing an understanding of techniques involving balance, arrangement, and garniture.
BALANCE
Balance is mostly used when referring to menu planning.
Some of the points considered are:
PORTION SIZE
Portion sizes are important for presentation as well as costing.
TEMPERATURE
Serve hot foods hot, on hot plates.
Serve cold foods cold, on cold plates
6.3 BUFFET ARRANGEMENT AND APPEARANCE
A buffet is for food display. The appearance sells the food.
The appearance of an abundance of food laid out is exciting and stimulating to the appetite. There are many ways create this look:
A variety of colour is as vital on a single plate.
Flat foods on flat trays on flat tables are uninteresting to the eye.
Replenish items as they become depleted.
Arrange platters so they still have interest even when portions have been removed.
Don’t spread items so far apart that the table looks half empty.
MENU AND SERVING SEQUENCE
COCKTAIL BUFFET
6.4 COLD PLATTER PRESENTATION
The cold platter is the mainstay of the buffet and offers the most opportunity for visual artistry.
Cold platters can range from a simple tray of cold cuts to elaborate constructions of pates, meats, poultry or fish decorated with aspic, truffles, and vegetable flowers.
BASIC PRINCIPLES OF PLATTER PRESENTATION
DESIGNING THE PLATTER
CHEESE PLATTER
Cheese trays are common on luncheon buffets as a main course item and on dinner buffets as a dessert item. Cheeses are presented differently from cold buffets.
Whole cheeses are more attractive than an arrangement of slices. This helps the guest identify the varieties.
An assortment of fresh fish is often included on a cheese tray, this adds a great deal to the appearance of a cheese presentation, and the flavors go well with cheese.
SANITATION
Cold food for buffets presents a special sanitation problem, this is because the food spends a great deal of time out of refrigeration while it is being assembled and decorated and again while it sits on the buffet.
For this reason, it is important to follow all the rules of safe food handling. Keep the food refrigerated whenever they are not being worked on. Also, keep them chilled until the last minute before they are brought out for service.
ENERGY CONSERVATION
Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service. For example, driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques.
Even though energy conservation reduces energy services, it can result in increased financial capital, environmental quality, national security, and personal financial security. It is at the top of the sustainable energy hierarchy.
Individuals and organizations that are direct consumers of energy may choose to conserve energy to reduce energy costs, promote economic security, or maximize profit. However, this can lead to unintended rebound effects, which can negate environmental benefits of conservation unless backstops are instituted to prevent overall consumption increases.

7.3 PREPARATION AND COOKING OF POULTRY
Poultry should be handled with strict sanitary measures during both cooking and preparation. Preparation
Thaw frozen chicken, Rock Cornish hen, turkey, and duck before cooking. All poultry must be thawed at chill temperatures (36°F to 38°F). Never thaw in water.
Thawed poultry should never be refrozen. Refreezing lowers quality and promotes bacterial growth.
Use thawed poultry as soon as possible. Do not hold in refrigeration more than 24 hours. Longer holding lowers quality and risks spoilage.
Whole turkeys, Rock Cornish hens, ducks, and chickens are wrapped in plastic bags. Remove whole poultry from the shipping containers, but leave in the plastic bag. To speed thawing, spread them out so that air can circulate. Cutup or quartered chickens should be thawed in the intermediate carton. If this carton has an overwrapping, remove it.
Turkeys weighing more than 16 pounds require 3 to 4 days to thaw, at 36°F to 38°F. Turkeys weighing less than 16 pounds require 2 to 3 days. Whole chickens and ducks require 18 to 24 hours and Rock Cornish hens need 12 to 18 hours.
Clean all poultry after thawing by removing any spongy, red lung tissue inside the back, loose membranes, pinfeathers, and skin defects. Wash poultry inside and out under cold, running water and drain. Refrigerate until needed.
NOTE: All cutting boards used for preparing poultry must be thoroughly sanitized after each use.
Cooking
Procedures for cooking whole turkeys, Rock Cornish hens, chickens, and ducks are described in the AFRS. Poultry maybe cooked using either moist or dry heat. These methods and their variations are explained as follows.
DRY HEAT METHODS.- Care should be taken to prevent the poultry skin from becoming too hard and dry while it is roasting. To prevent dryness, rub the skin of the chicken or turkey with salad oil or shortening. This is not necessary for duck because of its high fat content. If self-basting turkey is supplied, follow the package instructions for cooking. Place the poultry in an open pan, breast side up, on a V-shaped rack if available. A low oven temperature (350°F) should be used for chicken and Rock Cornish hen. Duck and turkey are cooked at 325°F.
If the bird starts browning too soon, aluminum foil may be placed over it to prevent overbrowning. The formation of a hard, dry crust can be prevented by occasionally basting the bird with pan drippings during roasting.
The Navy procures boneless, frozen, cooked, and uncooked turkey rolls. These rolls consist of light and dark meat. The instructions for preparing each type are included with the specific turkey roll and recipes in the AFRS. The boneless turkey roll is equal in quality and flavor to whole turkey, and it is easier and faster to prepare. It also permits accurate portion control, saves storage space, and eliminates waste. However, roast whole turkeys are often prepared for special meals.
As turkey is larger than most other poultry, it is more difficult to cook to the well-done stage without overdoing it. Care should be taken to cook it no longer than necessary; overcooking will result in the loss of juices and stringy, dry meat. The use of a meat thermometer inserted in the thickest part of the thigh muscle will give the internal temperature of the turkey. When the thermometer registers an internal temperature of 180°F to 185°F, the turkey has reached the required stage of doneness. The AFRS contains a timetable for roasting unstuffed turkeys.
MOIST HEAT METHODS.- In moist heat methods, the water should simmer rather than boil to avoid the toughening effect of high temperature on the fibers. Depending upon the cooking method used, temperatures will vary, but slow to moderate temperatures should be used at all times to develop maximum flavor, tenderness, color, and juiciness.
Intense heat will harden and toughen the protein, shrink the muscles, and dry out the juices, thus producing a less palatable product. All poultry should be cooked to the well-done stage. Follow the AFRS directions for preparation.
Pan-frying.- To panfry poultry, wipe the pieces dry, season them with salt and pepper, and roll them in flour. If a heavier coating (crust) is desired, dip the pieces in batter or a milk and egg mixture and roll them in soft bread crumbs before they are fried. Put approximately one-half inch of frying fat in a heavy frying pan and preheat to a temperature of 360°F to 365°F. Add the pieces of poultry to the hot pan. Turn the pieces frequently. Use tongs or two spoons to turn the pieces. Do not use a fork because puncturing the meat with the tines of the fork allows the juices to escape. Cook until well-done.
Oven Frying.- Dip the pieces of poultry in flour, milk and egg mixture, then into crumbs. Place poultry in a shallow pan. Pour the fat over the pieces to ensure an even coating. Cook in the oven.
Deep-Fat Frying.- To deep-fat fry poultry, wipe the pieces dry, season them with salt and pepper, and roll them in flour. If a heavier coating (crust) is desired, dip the pieces in batter or a milk and egg mixture and roll them in soft bread crumbs before they are fried. Place enough fat in the pan to completely cover the pieces of poultry. Preheat the fat to 325°F, then carefully lower the pieces into the fat. Do not crowd. The chicken may be cooked until done, or it may be browned in deep fat and placed in the oven to complete the cooking. Always allow the fat to regain the proper temperature before reloading the fryer.
The giblets (gizzard, heart, and liver) need no preparation other than ordinary washing in cold water before cooking. One precaution-the liver should be inspected closely to detect any sign of bile contamination. The bile sack is often broken during its removal from the liver. Bile damage is easily recognizable by a greenish brown or yellow color on the liver. Any liver indicating bile damage is unfit to eat and must be discarded.
After washing the giblets in cold water, you should place them in just enough cold salted water to cover, bring to a boil, then reduce the heat and simmer approximately 1 hour or until they are tender. (Livers cook much faster than gizzards and should be cooked separately.) Save the stock and chop the giblets (do not grind) for use in the gravy or dressing. Refrigerate them until they are ready to use
7.4 MEAT
Meat is animal flesh that is eaten as food .Generally, this means the skeletal muscle and associated fat and other tissues, but it may also describe other edible tissues such as offal Often, meat is used in a more restrictive sense—the flesh of mammalian species (pigs, cattle, lambs, etc.) raised and prepared for human consumption, to the exclusion of fish and other seafood, poultry, and other animals. Usage varies worldwide by culture, and some countries such as India have large populations that avoid the consumption of all or most kinds of meat. Game or bush meat is also generally distinguished from that produced by agriculture.
The consumption of meat has various traditions and rituals associated with it in different cultures such as kosher and halal and its production is generally regulated by state authorities as well. This article is mainly focused on that process from primary production to consumption.
The domestication of animals, of which we have evidence dating back to the end of the last glacial period allowed the systematic production of meat and the breeding of animals with a view to improving meat production. The animals which are now the principal sources of meat were domesticated in conjunction with the development of early civilizations:
Other animals are, or have been raised or hunted for their flesh. The type of meat consumed varies much in different cultures, changes over time, and depends on different factors such as the availability of the animals and traditions.
.
7.5 MAIN CONSTITUENTS
Adult mammalian muscle flesh consists of roughly 75 percent water, 19 percent protein, 2.5 percent intramuscular fat, 1.2 percent carbohydrates and 2.3 percent other soluble non-protein substances. These include nitrogenous compounds, such as amino acids, and inorganic substances such as minerals.
Muscle proteins are either soluble in water or in concentrated salt solutions.
Fat in meat can be either adipose tissue, used by the animal to store energy and consisting of “true fats” (esters of glycerol with fatty acids), or intramuscular fat, which contains considerable quantities of phospholipids and of unsaponifiable constituents such as cholesterol.
7.6 RED AND WHITE MEAT
The meat of adult mammals such as cows, sheep, goats, and horses is generally considered red, while fish and domestic chicken and turkey breast meat is generally considered white.

7.7 STORAGE OF MEAT AND POULTRY
Why is Chilling Meat and Poultry Important? | Raw meat and poultry products should be maintained at 40° F or below to greatly reduce the growth rate of any pathogenic bacteria that may be present on their surfaces. Chilling is required of all raw product unless it moves directly from the slaughter line to heat processing or cooking (made into hot dogs or luncheon meats, for example), which destroys pathogens. |
How is Meat and Poultry Chilled and Maintained at the Plant? | Meat and poultry products are chilled immediately after slaughter to acceptable internal temperatures which insure the prompt removal of the animal heat and preserve the wholesomeness of the products. Generally, red meat carcasses (which are above 90° F at the time of slaughter) are chilled in a blast cooler with rapidly moving chilled air, and, in some instances, a cold water shower.
Poultry is required to be chilled to 40° F or less within specified time frames, depending upon the size of the carcass. Whole birds and parts of major size are chilled in ice or ice and water media. Poultry parts are chilled in ice, air or water spray with continuous drainage. Giblets must be chilled to 40° or below within two hours of slaughtering the birds. |
How Does Packaging Prolong Storage Times? | Packaging is a physical barrier to cross contamination. Microorganisms exist everywhere in nature. They are in the soil, air, and water. The simple act of covering food keeps microorganisms from contacting the food. Covered perishable foods can be stored longer and at better quality than uncovered foods. Modified atmosphere packaging (MAP) and vacuum packaging help prolong storage (see following question). Refer to the charts on pages 5 and 6 for recommended storage times. |
How are Meat Products Kept Safe During Transportation? | To prevent rapid growth of pathogenic bacteria, perishable meat and poultry products should be kept cold (40° or below) or frozen (0° or below) during transport from the plant to a refrigerated warehouse or retail store. Microorganisms capable of causing foodborne illness either don’t grow or grow very slowly at refrigerated temperatures of 40°F. Freezing keeps food safe by slowing the movement of molecules, causing any microbes present to enter a dormant stage. There’s also no risk of dripping juices to contaminate nearby products and storage areas. |
How are Meat Products Kept Safe During Loading and Unloading? | One of the extremely important places in handling perishable meat and poultry products safely is the receiving dock. Employees should verify the products are at a safe temperature upon arrival. According to the Food and Drug Administration Food Code (which covers retail establishments, not federal) the temperature must be at 5° C (41° F) when received. Employees should also check the conditions of the packaging materials and the sight and smell of the products.. |
In the Store, How Should Meat Products Be Safely Handled? | To protect perishable food from contamination after receipt at the store, food employees must wash their hands before handling it. Raw foods must be kept separate from cooked ready-to-eat foods during storage, preparation, holding and display. Some local jurisdictions may require food handlers to wear gloves.
Frozen foods must be maintained frozen. When “thawed for your convenience,” frozen food must be kept under refrigeration that maintains the food at 5° C (41° F) or below, or completely submerged under running water following strict guidelines outlined in the Food Code. |
What Types of Food Are Dated? | “Open” dating, or dates you can read, are found primarily on perishable foods such as meat, poultry, eggs and dairy products. “Closed” or “coded” dating might appear on shelf-stable products such as cans and boxes of food. |
Types of Dates | There are several types of dates:
|
Safety After Date Expires | Except for “use-by” dates, product dates don’t always refer to home storage and use after purchase. But even if the date expires during home storage, a product should be safe, wholesome and of good quality — if handled properly and kept at 40° F or below. See the accompanying refrigerator charts for storage times of dated products.
Foods can develop an off odor, flavor or appearance due to spoilage bacteria. If a food has developed such characteristics, you should not use it for quality reasons. If foods are mishandled, however, food borne bacteria can grow and cause food borne illness — before or after the date on the package. For example, if a package of hot dogs is taken to a picnic and left out several hours, the hot dogs wouldn’t be safe to use, even if the date hasn’t expired. Other examples of potential mishandling are products that have been: defrosted at room temperature more than two hours; cross contaminated; or handled by people who don’t use proper sanitary practices. Make sure to follow the handling and preparation instructions on the label to ensure top quality and safety. |
Storage Times | Since product dates aren’t a guide for safe use of a product, the consumer should follow these tips to store the food and use it at top quality.

7.8 FISH
7.9 INTRODUCTION
They are classified according to the type or by the origin e.g. fresh water fish, salty water fish.
They are three main types of fish:
White fish have flesh which is white & dry because of fat which is usually stored in the liver.
The oil is used for vitamin supplement e.g.
it darker in colour &more nutritive &difficult to digest.
They supply plenty of protein but are too expensive.
Fish is a good sauce of protein & people should be encouraged to eat its easier to digest than meat.
8.0 COMPOSITION COD LIVER OIL
The oil is distributed throughout the fish making
It’s a protein food which closely resembles meat in structure & composition but is easier to digest & less satisfying.
A flesh fish is made up of muscles divided into flakes held up together by less connective tissue known as collagen which when cooked by moist heat it changes to gelatin causing flakes to fall apart, its for this reason that fish is more tender than meat &cooks faster &may break up when serving.
Fish is suitable for invalids as it’s easier to eat &digest.
8.1 NUTRITIVE VALUE OF FISH
Protein
Fish is a good source of first class protein ranging from 17.5-20.2%.
Fat (oily fish)
The amount of oil may be up to 15%, while in white fish it’s about 1-4%.

Potatoes are one of the most important of all foods. It’s a starch food and also can be regarded as a vegetable.
Botanically potato is a tuber which is an enlarged underground stem with buds (or eye) that become new shoots.
Potato is a vegetable but because of its high content of starch it serves its function as a starchy food.
Potatoes are classified according to their starch content. The amount of starch determines the use for which they are usually considered most suitable.
Within each group is a range of starch and moisture content e.g. waxy potatoes have different moisture content depending not only on variety of potato but also on growing and storage conditions.

10.0 RICE
Rice is a keystone of the grass family that produces a vast number of grains consumed by humans. It has been under intensive cultivation originating in Asia for over 4,000 years and has since spread across the world, where almost a third of the population depends on rice for vital nutrition. This grass is in the genus Oryza, which is separate from that of wheat, spelt, and similar grass crops, although it resembles them in structure.
Like most grasses cultivated for human consumption, rice is an annual crop that needs to be resown for harvest each year. It is grown in partially submerged fields, also called paddies, and when mature, the plant reaches a height of approximately 3 feet (1 meter). Rice has a classically grass-like appearance, with a small cluster of kernels at the top of a long stalk. It’s harvested when it turns golden, and the resulting crop is threshed to remove the hulls. Many developing nations use the chaff as fuel for electricity generation.
There are many cultivars of rice grown around the world, although they can primarily be broken up into long grain varieties such as jasmine and basmati and short grain styles such as those used to make sushi. If the bran, or outer part of the grain, is left on, the resulting product is considered to be brown rice. If removed, the grain is white rice. Many cultures prefer brown because it has a higher nutritional value than white, including important levels of vitamin B.
Rice is a very versatile grain, which can be ground into flour for the gluten intolerant, cooked slowly in paella, or steamed to accompany a wide array of Asian dishes. Popular dishes with it include sticky rice with mango, which uses a special type of short grain rice that comes in white, brown, and black varieties. The black variety is known in Thailand as “forbidden rice.”
Shorter grain rices tend to stick together better and are used for sushi and other dishes in which it needs to be shaped. Longer grain, such as basmati, is looser and frequently appears as a side dish. Rice is also used in the production of grain alcohols such as sake, popular in Japan.
Some white rice is sold enriched with vitamins and minerals in an attempt to provide more complete nutrition to the purchaser, especially in impoverished regions where it is the primary staple food. Some companies have genetically modified rice in an effort to make it retain more nutrients, but these efforts have not been entirely successful.
10.2 METHODS OF COOKING RICE.
BOILING METHOD
Appropriate Rice: All white rice
Boiling rice is the simplest method of preparation. The boiling method produces tender grains of rice that are not sticky and can be used for garnishes, soups and salads.
STEAMING AND SIMMERING METHODS
Appropriate Rice: All
Unlike boiling, the simmering and steaming methods use a measured amount of liquid to ensure the proper texture of the finished product. The gentler, less agitated heat of simmering releases less starch from the rice, keeping it from becoming sticky. This method yields long grain rice that is tender and fluffy. It is good for rice used as a starch to accompany stews and other entrées. Short grain rice cooked by this method is tender with unbroken grains, as with sushi rice.
Steamed Rice
Essentially cooked in the same manner as simmered rice, this process is performed in a commercial steamer. Rice and measured liquid are brought to a boil on the range, then placed in a shallow hotel pan and cooked uncovered in the steamer. Rice cookers are another variation on steaming and simmering methods. This method produces a consistent product by employing a thermostat and timer that cooks the rice at a simmer for precisely the right amount of time. Rice cooker thermostats can also be set to hold rice hot without overcooking it.
PILAF METHOD
Appropriate Rice: Long grain (white, brown, basmati, etc.)
The pilaf method of cooking rice is characterized by the use of a flavored liquid (usually stock) and the addition of aromatic ingredients. The pilaf method is different from methods previously mentioned, as it begins with sweating aromatic ingredients. The rice is added and coated in the same fat, hence the classical French name riz au gras. Like the simmering method, the liquid used in making a pilaf is measured to ensure proper texture when done.
RISOTTO METHOD
Appropriate Rice: Medium grain or Arborio
Risotto is a classic Italian cooking method for medium grain rice. The risotto method cooks rice at an active simmer while stirring. Hot seasoned liquid is continually added in small amounts until the rice is fully cooked. The result is a hearty dish of medium grain rice bound in a rich sauce thickened by the rice’s own starch. Traditionally Risotto should be rich in flavor and for this reason a seasoned stock or wine are the liquids used. A wide range of additional ingredients can also be added.
10.3 RICE STORAGE:
UNCOOKED:
Milled rice (white, parboiled or pre-cooked):
If stored properly, it can keep for two years on the pantry shelf.
Whole grain rice (brown, red or black):
Long-grain rice: Includes the Indian basmati.
Short-grain rice: The family of Italian Arborio rice, used to make risotto; also used in sushi.
Wild rice: Not really rice at all. Wild rice is a remote relative of white rice, actually a long-grain, aquatic grass.
Brown rice: Healthful, unrefined rice (that means it still has the bran and germ that are removed from white rice) with a slightly nutty flavor.

11.0 VEGETABLES
Vegetables are officially defined as edible roots, stems, leaves and flowers. They form part of our daily meals and it is therefore important to understand the preparation of vegetables changes that occur during preparation and how they are handled.
They are source of nutrients in a meal and especially provide vitamin.
The term vegetable can include part seed, shoots, flowers etc.
11.1 CLASSIFICATION OF VEGETABLES
-watercress
-cauliflower
-kunde
-lettuce
-brussel sprouts
Pumpkins, pepper.
(Wild grown)
11.2 BUYING AND STORING OF VEGETABLES
11.3 VEGETABLE PREPARATION
These vegetables may be either steamed or prepared in a fireless cooker.
The usual way is to cook them in water. Clean the vegetables. Then put them on to cook in enough water to keep from burning, but use no seasoning. When the vegetables are tender there should be only a little fluid left and those who eat of the vegetables should take their share of this fluid, for it may contain as high as one-half to two-thirds of the salts. When served, let each one season to taste. Avoid the use of vinegar and all other products of fermentation as much as possible. Lemon juice will furnish all the acid needed for dressing.
The vegetables may be dressed with salt, or salt and butter, or salt and olive oil, and at times with cream, or with the natural gravy from meats, but avoid the use of flour and milk dressings, usually called cream gravy. These vegetables may also be eaten without any dressing.
The water is drained off from corn on the cob, asparagus, artichokes and unpeeled beets.
Vegetables should not be soaked in water, for they lose a part of their value if this is done. Cucumbers may be soaked in water to remove a part of the rank flavor, before being peeled.
“Spinach” is prepared as follows: Wash thoroughly. Put about two tablespoonfuls of water in the bottom of the kettle. Put over the fire and let the spinach wilt. Its juice will then begin to pour out and the spinach will cook in its own juice. Let it cook slowly until tender. Serve the spinach with its proportion of the juice. At first this will taste rather strong, but after a while a person will not want the dry, tasteless mess that is drained, usually served in hotels and restaurants. If some of the roots are left on the spinach, it tastes milder. The roots contain sugar.
Some of these vegetables, such as summer squash, onions and parsnips may be baked. Onions are very good sliced and broiled, but they should never be fried. Beets are good baked, and especially are this true of sugar beets. Radishes are very delicate and delicious when peeled and boiled, but their preparation is tedious. Egg plant is to be stewed, but not fried. As usually served, dipped in egg, rolled in crumbs and fried it is very indigestible.
Beet greens are excellent. They are best if the beets are pulled very young and both the roots and the leaves are used. Turnip tops, dandelion, mustard and Swiss chard are other greens that are good. All of them are prepared like spinach, except that more water is necessary. However, do not use much water.
Those who say that the various vegetables are unfit to eat and act accordingly are missing some good food. The vegetables all contain crude fibre, but they hurt the stomach and intestinal walls no more than they hurt the mucous membrane of the tongue. They furnish some bulk for the intestines to act upon, which is good and proper. All animals need some bulky food, otherwise they become constipated.
Tomatoes are best raw. If they are stewed they are to be cooked plain. Adding crackers and bread crumbs is a mistake. They taste all right without sugar, but a little may be used as dressing.
“Vegetable soup”: Take equal parts of about four vegetables, any that you like. Slice and cook in plain water until tender. When done add enough water or hot milk to make it of the right consistency. Season to taste. One of the constituents may be starchy, such as potatoes, barley or rice, but the rest should be succulent vegetables.
VEGETABLE CUTS
Chunks A piece of cut vegetable larger than 3.75cm/1¾-inches. Usually cut before cooking. |
|
Cubes Pieces of vegetables from 12mm/½ -inch to 36mm/1½-inches square. Can be cut before or after cooking. |
|
Dice Pieces of vegetables between 6mm/¼-inch and 12mm/½ -inch square. Can be cut before or after cooking. |
|
Grated Thin pieces of vegetables created using a grater. They can be any length depending on the vegetable used but are always wafer thin. |
|
Julienne Strips of vegetables usually 3mm/ ⅛- inch square up to 5cm/ 2 inches long standard. Often a mandoline is used for accuracy. Often used as a garnish. |
|
Mashed Vegetables which have already been cooked until soft then further broken down with a fork or masher. |
|
Matchsticks
Thin “sticks” of vegetables no thicker than 6mm/¼-inch square and 5cm/2-inches long
|
|
Paysanne
Very thin slices of vegetables no larger than 6mm/¼-inch square. Most often used as a garnish |
|
Purée Vegetables which have usually already been cooked until soft then mashed then made smooth by rigorous beating or passing through a sieve. With some vegetables a food processor can be used. |
|
Shred Vegetables cut into thin strips generally no wider than 6mm/¼-inch. Usually done before cooking. |
|
Slices Vegetables cut into similar size flat pieces. Can be lengthways or width ways, from 3mm/⅛-inch to 2.5cm/1-inch thick. The use of a mandoline makes slicing vegetables much easier and you can achieve very thin even slices. |
|
SulfrinoBalls Sulfrino vegetable balls are made with a very small melon scoop, sometimes called a Parisienne scoop, up to 12mm/½-inch in diameter. Most usually used for garnishes. |
There are lots of different ways of cooking vegetables. Each has its own advantages and disadvantages, and each gives the vegetables a particular texture and flavor. Some methods let you use spices; others let you keep the veggies crisper. And some methods are just better suited to certain vegetables.
So which method do you pick? In this section, I’ll go over the different methods for cooking vegetables, and some of their pros and cons.
Boiling is one of the easiest ways to prepare vegetables. All you need is a cooking pot, some water, some vegetables, and maybe a bit of salt. It’s quick and convenient!
But boiling vegetables causes them to lose some of their nutritional value. The boiling water leeches some of the vitamins and nutrients, and even some of the flavor, right out of the veggies. The best way to minimize that nutrient loss is to make sure that they spend as little time as possible in the boiling water. And just how you do that depends on what kind of vegetable you’re boiling.
To learn how to get the most out of your vegetables, check out this article on boiling vegetables for all the details.
Steaming is a great method for cooking vegetables. It cooks the vegetables and softens them up, but because they’re not immersed in water, they don’t lose as many nutrients. It also preserves more of the flavor than boiling does.
And like boiling, steaming is super convenient. Even though you can get a special cooking appliance, a steamer, you really don’t need one. If you have a pot, some water, and a steaming basket, you’re all set. Or if you don’t have a steaming basket, even a colander can do the trick. There’s even a way to steam vegetables using just a pot and a bit of water. What could be easier?
For more information and detailed instructions, check out this article on how to steam vegetables.
Sautéing vegetables, or stir-frying them, mean cooking them over fairly high heat, and stirring them often. The high heat helps them cook quickly, which minimizes nutrient loss. And stirring them keeps them from burning!
Sautéing is a really tasty way to cook vegetables. They keep a lot more flavor than boiling or even steaming, so that you taste how delicious the veggie really is. And it also lends itself really well to seasoning the vegetables. A little bit of oil and spices or a tasty marinade can really make your vegetables go from good to outstanding.
Unlike some of the other methods for cooking vegetables, though, you really have to keep an eye on sautéing vegetables. They can burn pretty quickly!
Find out more about sautéing in this article on how to make sautéed vegetables.
I like to roast vegetables in the fall or winter, when having the oven on warms up the kitchen in a wonderful way, and the smell of delicious food spreads through the house. And a lot of fall vegetables like squash taste so great when they’re roasted.
One of the great things about roasting vegetables is that even though it takes a while to cook, the preparation time is pretty much non-existent – just toss the veggies with a bit of oil and herbs, put them in a baking dish, and let them roast. It’s especially nice when the rest of your meal takes a little more attention, so that you can work on it in peace.
Roasting gives the vegetables a unique flavor that you don’t get by boiling or steaming. Cooking them slowly in the oven helps them caramelize a little bit, bringing out their natural sweetness and enhancing their flavor. And it’s so easy to add a few delicious herbs and spices. Yum!
To find out more about how to do it, check out this article on roasted vegetables.
Some vegetables are just better on the grill. Grilling gives that special cooked outdoors, perfectly browned taste that no other cooking method can match. And you can easily marinate the vegetables, or add some herbs or a sauce to them before cooking to give them some extra flavor.
Zucchini, with just a bit of oil, garlic, salt and pepper is one of my favorite vegetables to grill.
Grilling isn’t quite as convenient as some of the other cooking methods though. For one thing, you need a grill. And that also means it’s usually more of a warm weather kind of meal. But you also have to keep a close eye on the vegetables while they’re cooking. They’ll usually need to be flipped, and checked to be sure they’re not burning. Not as convenient, but well worth the effort!
Braising is a cross between steaming and boiling. Instead of cooking the vegetables by completely immersing them in boiling water, you only add enough water to cover about half the vegetables.
Like steaming, it cooks the vegetables a bit more gently than boiling. But it’s usually a bit quicker than just steaming, since part of the vegetables is in the water. And using just a bit of water means that you don’t lose as many nutrients or flavor, so you get extra delicious vegetables.
12.0 SANDWICHES AND CANAPES
12.1 INTRODUCTION
They are two or more layers of thin slices of bread with sweets or savory fillings.
Fillings are ingredients put in between slices of bread can either be sweet or savory e.g. fruits or vegetables.
Spread are ingredients applied on slices of bread before the fillings are put.e.g.butter, margarine.
12.2 TYPES OF FILLINGS
Savory fillings
Sweet fillings
INGREDIENTS
12.3 TYPES OF SANDWICHES
They are made from two slices of bread or two halves of a roll, a spread and a filling.
They are called simple because they are prepared from just two slices of bread.
Simple sandwiches range from a single slice of cheese or meat between two slices of buttered bread to complex constructions like the submarine sandwich.
They are made with more than two slices of bread and with several ingredients in the filling.
A club sandwich is an example of a multidecker sandwich made of three slices of toast and filled with sliced chicken or turkey breast, mayonnaise, lettuce, tomato and bacon.
It’s made with a single slice of bread like large canapés. The filling or the topping should be attractively arranged and garnished
They are small, fancy sandwiches generally made from light, delicate ingredients and bread that has been trimmed of crusts. They are often cut into fancy shapes. Fillings and spreads can be the same as those for canapés
These are sandwiches in which fillings are wrapped like a Mexican burrito, in a flour tortilla or similar flatbread. They may be served whole or cut in half if large.

Protein foods like
Meats, poultry, fish and shell fish, eggs, cheese cold meats products like salamis, polony, ham, E.T.C
1. Keep the salad off the rim of the plate. Think of the rim as a picture frame and arrange the salad within this frame. Select the right plate for the portion size, not too large or too small.2. Strive for a good balance of colors. Plain iceberg lettuce looks pale and sickly all by itself, but it can be enlivened by mixing in darker greens and perhaps a few shreds of carrot, red cabbage, or other colored vegetable. On the other hand, don’t go overboard. Sometimes just a few shades of green will create a beautiful effect. Too many colors may look messy. 3. Height helps make a salad attractive. 4. Cut ingredients neatly. 5. Make every ingredient identifiable. 6. Keep it simple. |

The wide variety of types of salads make it hard to give advice that applies to al salads, but some standard rules of thumb that you must pay attention to are:
Ø Use the freshest ingredients available | |
Ø Mild tasting vegetables like leafy greens must offer texture to the plate by being crisp, and make sure they are free from sand or blemishes. If serving a dressing , dress the salad by lightly tossing with the dressing prior to service when possible to insure the proper mixture of flavor. | |
Ø You may wish to dress dense or strong tasting vegetables by marinating them a day in advance to balance their flavor. | |
Ø Plate and serve cold salads at the last possible minute in a cold dish | |
Ø Never overcrowd the plate. It is a good idea never to let the salad presentation flow outside of the inner rim of the plate. |
13.7 SALAD BAR ARRANGEMENT
Making up a salad bar is an easy way to entertain during summer. As with meal preparations like this, there are no exact recipe amounts, as this is more of an idea rather than an actual recipe.
Steps
Set up a table to lay out your salad bar.
Cover the table with a pretty tablecloth suitable for the occasion.
Place the flatware and plates at the start of the salad bar service.
Arrange the salad bar items on the table.
Make sure to keep hot foods hot and cold foods cold. In other words have something to keep foods at the appropriate temperature.
Chilled salad dressings such as Ranch, French, Blue Cheese or Italian
Have your guests pick up their appropriate dinnerware, flatware and napkins before moving down the salad bar to select their salad fixings.
13.8 DRESSINGS
Sauces for salads are often called “dressings”. The concept of salad dressing varies across cultures.
In Western culture, there are three basic types of salad dressing:
13.9 INGREDIENTS USED IN SALAD DRESSING
The Oils
Generally speaking, any oils labeled “vegetable oil” or “salad oil” are fine for making a basic dressing. You could also use any light, neutral-flavored oil like safflower, canola or soybean oil. One of the most common variations is to substitute olive oil for salad oil. If you do this, make sure you use extra virgin olive oil, not the cheaper, “light” varieties. When you consider the wide range of flavored oils that are available today, including such distinctive oils as walnut or avocado, the possible variations on the basic vinaigrette formula are literally endless.
The Vinegars
The most neutral flavored vinegar is white vinegar, but we wouldn’t likely use this in a dressing. At the very least, use white wine vinegar. But the flavors and types of specialty vinegars, like balsamic, sherry or raspberry, are as varied and diverse as can be. Cider vinegar is made from apples and is a good choice for fruity vinaigrettes. Balsamic vinegar, sweet, dark and aged in specially treated wooden casks, is one of the most sublime vinegars you can find. Another interesting choice, especially for Asian-flavored vinaigrettes, is rice vinegar, which is made from fermented rice.
The Juices
Lemon juice is a nice component to add to dressing. It’s usually used to complement and enhance the vinegar, rather than replacing it altogether — although a simple dressing of olive oil and lemon juice drizzled over a fresh summer salad is hard to beat.
For that matter, you can use all kinds of juices in vinaigrettes, not just lemon — though citrus fruits such as lemon, lime and orange juice are used most commonly because of their high acid content. Orange juice adds sweetness in addition to tartness. Each citrus fruit has its own unique flavor profile, but the overall vinaigrette formula is the same.
Egg Yolk
Egg yolk is an essential ingredient in mayonnaise and other emulsified dressings. For safety pasteurized eggs should be used and the finished product should be refrigerated to avoid spoilage.
The Seasonings
A simple dressing doesn’t need more seasoning than a bit of kosher salt and ground white pepper. But minced garlic, onion, shallot and herbs (fresh and dried) are often part of the mix, along with spices such as black pepper, celery seed, and paprika and so on. Other ingredients, such as mustard or Worcestershire sauce, are not uncommon.
Honey happens to be a great addition to a dressing, firstly because it adds sweetness, which is nice sometimes to counterbalance the tartness from your vinegar, citrus or whatever. But also because it helps stabilize the emulsion. A dressing with honey in it will remain emulsified for a long time — certainly longer than it takes to eat a salad. Honey vinaigrettes are great for presentations, where you don’t want the oil and vinegar separating all over the plate.
Toppings and garnishes
Popular salad garnishes are nuts, croutons, anchovies, bacon bits (real or imitation), garden beet, bell peppers, shredded carrots, diced celery, watercress, sliced cucumber, parsley, sliced mushrooms, sliced red onion, radish, French fries, sunflower seeds (shelled), real or artificial crab meat (surimi) and cherry tomatoes. Various cheeses, berries, seeds and other ingredients can also be added to green salads. Cheeses, in the form of cubes, crumble, or grated, are often used, including blue cheese, Parmesan cheese, and feta cheese. Color considerations are sometimes addressed by using edible flowers, red radishes, carrots, various colors of peppers, and other colorful ingredients.
EMULSION IN SALAD DRESSING
Definition: In the culinary arts, an emulsion is a mixture of two liquids that would ordinarily not mix together, like oil and vinegar.
There are two kinds of emulsions,
An example of a temporary emulsion is a simple vinaigrette. You combine the oil and vinegar in a jar, mix them up and they come together for a short time.
The Vinaigrette
We expect a lot from oil and vinegar dressings, or vinaigrettes, as they’re also called. Even the simplest one is asked to do nothing less than defy the laws of nature.
That’s because oil and vinegar don’t mix. No doubt you’ve seen this yourself — shake up a bottle of salad dressing and the two parts come together. But set the bottle down and in seconds they start to separate again, until all the oil is at the top and all the vinegar is at the bottom.
The best we can do is encourage them to come together for a little while, which they will grudgingly do, provided we shake, stir or otherwise mix them up really well.
We call that a temporary emulsion — temporary because the oil and vinegar begin to separate as soon as you stop mixing, stirring or whatever. Here are a few tips and tricks to help your vinaigrettes turn out perfectly every time.
Vinaigrette Variations
Here are a few to get you started:
Mayonnaise is an example of a permanent emulsion, consisting of egg yolks and oil. Egg yolks and oil would not naturally mix together, but by slowly whisking the oil into the egg yolks, the two liquids form a stable emulsion that won’t separate.
Mayonnaise is what’s called an emulsion, which is a fancy way of saying that we’re able to make the yolk of a single large egg yolk hold up to a full cup of oil.
The trick is to add the oil VERY slowly at first, while constantly whisking the yolk. Add the oil too fast and your emulsion will break. Making a one-egg mayonnaise is a bit tricky because you literally have to add the oil a drop at a time at first. If you used three or four yolks you wouldn’t have to worry as much — but using four yolks means you’d make about a quart of mayonnaise!
Hollandaise sauce is another permanent emulsion, which is made of egg yolks and clarified butter.
Certain substances act as emulsifiers, which mean they help the two liquids come together and stay together. In the case of mayonnaise and Hollandaise, it is the lecithin in the egg yolks that acts as the emulsifier. Lecithin, a fatty substance soluble in both fat and water, will readily combine with both the egg yolk and the oil or butter, essentially holding the two liquids together.
In a stable emulsion, what happens is that droplets of one of the liquids become evenly dispersed within the other liquid. The resulting liquid is thicker than the two original liquids were. In the case of salad dressing, oil droplets are suspended within the vinegar.
The following are examples of common salad dressings:
13.0 BREAKFAST PREPARATION
13.1INTRODUCTION
Breakfast is the first meal taken after rising from a night’s sleep, most often eaten in the early morning before undertaking the day’s work. Among English speakers, “breakfast” can be used to refer to this meal, or more commonly, to refer to a meal composed of traditional breakfast foods (such as eggs, oatmeal and sausage) served at any time of day.
Breakfast foods vary widely from place to place, but often include a carbohydrate such as grains or cereals, fruit and/or vegetables, a protein food such as eggs, meat or fish, and a beverage such as tea, coffee or fruit juice. Coffee, tea, juice, breakfast cereals, pancakes, sausages, bacon, sweet breads, fresh fruit, vegetables, eggs, mushrooms, baked beans, muffins, crumpets and toast with butter or margarine and/or jam or marmalade are common examples of breakfast foods, though a large range of preparations and ingredients are associated with breakfast globally.
Nutritional experts have referred to breakfast as the most important meal of the day, citing studies that find that people who skip breakfast are disproportionately likely to have problems with concentration, metabolism, and weight. Other nutrition experts believe the claimed metabolic benefits are a common myth, noting the impact on cognition has been found among children, but not among adults, and explain that the connection with increased weight is likely behavioral compensating with snacks and/or eating more later—and therefore not inevitable.
13.2 EGGS
COMPOSITION
A whole egg consists of a yolk, a white, and a shell. In addition it contains a membrane that lines the shell and forms an air cell at the large end, and two white strands called chalazae that hold the yolk centered.
The yolk is high in both fat and protein, and it contains iron and several vitamins.
Its color ranges from light to dark yellow, depending on the diet of the chicken.
The white is albumin protein, which is clear and soluble when raw but white and firm when coagulated. The also contain sulfur. The white has two parts: a thick portion that surrounds the yolk, and a thinner, more liquid potion outside of this.
The shell is fragile but it is also porous, allowing odors and flavors to be absorbed by the egg and allowing the egg to lose moisture even if unbroken.
GRADES AND QUALITY
GRADES
Eggs are graded on the quality. There are three qualities: AA, A and B.
The best grade (AA) has a firm yolk and white that stand up high when broken onto a flat surface and do not spread over a large area. In the shell, the yolk is well centered and the air sac is small.
As they age, they lose density. The thin part of the white becomes larger, and the egg spreads over a larger area when broken, and the air sac becomes larger as the egg loses moisture through the shell.
MAINTAINING QUALITY
Proper storage is essential for maintaining quality. Eggs keep for weeks if held at 36 degrees F but lose quality quickly if held at room temperature. Store eggs away from foods that might pass on undesirable flavors or odors.
GRADES AND USE.
Grade AA is the best to use for fried or poached eggs. Lower grades spread out too much to produce a high quality product. For hard cooked eggs, use either grade A eggs or grade AA that have been held a few days in the refrigerator.
Grade B eggs are suitable for use in baking, if they have developed no strong flavors, they may be used for scrambled eggs, where the firmness of the whole egg is less important.
SIZE
Eggs are also graded by size. Each size differs from the next by 3 ounces or 85 grams. Most food service operations use large eggs, and recipes in most books are based on this size.
MARKET FORMS
These are most often used for breakfast cookery.
Frozen eggs are usually made from high-quality fresh eggs and are excellent for use in scrambled eggs, omelets, French toast, and in baking. They are pasteurized and are usually purchased in 13.6kg cans. These take at least two days to thaw at refrigerator temperatures.
SANITATION
In the recent years, cases of salmonella food poisoning have been caused by raw or under-cooked eggs. As a result, cooks have been made more aware of egg-related sanitation concerns. Pasteurized egg products are used in more operations.
EGG SUBSTITUTES
Eggs yolks are known to be high in fat and also cholesterol. Efforts to reduce cholesterol in the diet have led to the development of commercial egg substitutes:
Egg substitutes that can be used to make such dishes as scrambled eggs, omelets, and custards are made of pasteurized eggs whites with the addition of a blend of ingredients to substitute for the yolks, such as vegetable oil, milk solids, vegetable gums, and salt, emulsifiers, and vitamins additives. They are sold in bulk liquid form, usually frozen, and be substituted, ounce for ounce, for whole liquid eggs in most egg preparations.
Eggless egg substitutes contain no egg product. They are made of flours or other starches, plus vegetable gums and stabilizers, and, sometimes, soy protein. They are intended for use in baked goods only and are not suitable for use in breakfast egg preparation or custards.
GENERAL COOKING PRINCIPLES
When cooking eggs avoid high temperatures and long cooking times in short do not overcook. Overcooking produces tough eggs, causes discoloration and affects flavor.
Coagulation
Eggs are largely protein, so the principle of coagulation is important to consider.
Eggs coagulate at the following temperatures:
Egg white coagulates or cooks before yolks. This is why it is possible to cook eggs with firm whites but soft yolks.
Also when the eggs are mixed with a liquid, they become firm at a higher temperature.
As the temperature of coagulation is reached, the eggs change from semi liquid to solid, and they become opaque. If their temperature continues to rise, they become even firmer. An overcooked egg is tough and rubbery. Low temperatures produce the best-cooked eggs.
If egg-liquid mixtures such as custards and scrambled eggs are overcooked, the egg solids separate from the liquids, or curdle. This is often seen as tough, watery scrambled eggs.
Sulfur
The familiar green ring you often see in hard-cooked eggs. It is caused by cooking at high temperatures or cooking too long. The same green colour appears in scrambled eggs that are overcooked or held too long in the steam table.
The ring results when the sulphur in the egg whites reacts with the iron in the yolk to form iron sulphide, a compound that has a green colour and a strong odour and flavour.
In order not to achieve green eggs is to use low temperatures and short cooking and holding times.
Foams
Beaten egg whites are used to give lightness and rising power to soufflés, puffy omelettes, cakes, some pancakes and waffles, and other products. Guidelines how to handle egg whit properly:
When separating eggs, be careful not to get any yolk in the white. Yolks contain fats. Use very clean equipment when beating whites.
A small amount of lemon juice or cream of tartar gives more volume and stability to beaten egg whites.
Remove them from the cooler 1hour before beating
Beaten egg whites should look moist and shiny. Overbeaten eggs look dry and curdled and have lost much of their ability to raise soufflés and cakes.
When making sweet puffed omelettes and dessert soufflés add some of the sugar to the partially beaten whites and continue to beat to proper stiffness. (This will take longer than when no sugar is added).The soufflé will be more stable before and after baking.
COOKING EGGS
The term hard-boiled egg is not a good one because eggs should be simmered instead of boiled.
Eggs may be simmered in water to the soft, medium, or hard-cooked stage.
The principles of cooking eggs in the shell are applicable to poached eggs. The only difference between the two items is the shell.
This difference, of course, complicates the cooking process. The object is to keep the eggs egg-shaped- that is, in a round, compact mass rather than spread all over the pan.
Standards of quality for poached eggs.
Fried eggs are an especially popular breakfast preparation .They should always be cooked to order and served immediately. The choice of cooking fat is a matter of taste and budget. Butter has the best flavour, but margarine or oil may be used.
Standards of quality for fried eggs
White should be shiny, uniformly set, and tender, not browned, blistered, or crisp at edges.
Yolk should be set properly according to desired doneness. Sunny-side yolks should be yellow and well rounded. In other styles, the yolk is covered with a thin layer of coagulated white.
Relatively compact, standing high. Not spread out and thin.
Shirred eggs resemble fried eggs, except that they are baked in individual serving dishes rather than fried. They may also be baked with or garnished with a variety of meats and sauces.
Scrambled eggs are cooked to order. They may be made in larger quantities. They should be undercooked if they are to hold for volume service, as they will cook more in the steam table.
Do not overcook scrambled eggs or hold them too long. Overcooked eggs are tough and watery, and they eventually turn green in the steam table.
Scrambled eggs should be moist and soft, unless the customer requests “scrambled hard”
Additions to scrambled eggs
Flavor variations may be created by adding any of the following ingredients to scrambled eggs before serving:
There are different types like plain, French omelette etc. but French omelette remains the most popular
Example:
French omelette
Omelettes are sophisticated scrambled eggs
Elements of preparing omelette:
13.3 BREAD
Bread is a staple food prepared by baking a dough of flour and water and often additional ingredients, such as butter or salt to improve the taste.
White bread (left) and brown bread.
Classic French bread, Boule.
Bread is also made from the flour of other wheat species (including durum, spelt and emmer), rye, barley, maize (corn), and oats, usually, but not always, in combination with wheat flour. Spelt bread continues to be widely consumed in Germany, and emmer bread was a staple food in ancient Egypt. Canadian bread is known for its heartier consistency due to high protein levels in Canadian flour.
Make sure your yeast is fresh. Active dry yeast, sold in individual packets, is the easiest type to use, and keeps well in your pantry. There is always a ‘best if used by’ date on the packages, and you should follow this rigorously. If you are going to take the time to make bread, fresh yeast is essential.
Cake yeast, if you can find it, really makes a wonderful loaf of bread. This form of yeast is fresh, stored in the refrigerator, and is very perishable. When you buy it, use it within 1-2 days, or it may mold.
The temperature of the water, whether used to dissolve the yeast, or added to a yeast/flour mixture, is critical. Until you get some experience, use a thermometer. When the yeast is dissolved in the water or other liquid, the temperature must be 110 to 115 degrees. When the yeast is combined with flour and other dry ingredients, the liquid temperature can be higher; about 120 to 130 degrees.
The flour you choose for your bread also makes a difference in the quality of the final product. Bread flour makes a superior loaf. This flour is higher in protein content, and protein, or gluten, is what gives bread its unique texture.
When water is added to flour, two proteins, glutenin and gliadin, combine to form gluten. Gluten forms a network of proteins that stretch through the dough like a web, trapping air bubbles that form as the yeast ferments. This creates the characteristic air holes of perfect bread.
All purpose flour will also work just fine in most bread recipes. Don’t use cake flour because there isn’t enough protein in that type, and your bread will fall because the structure won’t be able to withstand the pressure of the gasses the yeast creates.
Whole grain flours and other types of flour add color, texture, and flavor to breads. These flour types don’t have enough gluten to make a successful loaf on their own, so all purpose or bread flour is almost always added to provide structure.
The type of liquid you use will change the bread characteristics. Water will make a loaf that has more wheat flavor and a crisper crust. Milk and cream-based breads are richer, with a finer texture. These breads brown more quickly because of the additional sugar and butterfat added to the dough. Orange juice is a nice addition to whole wheat breads because its sweetness helps counter the stronger flavor of the whole grain.
Fats like oils, butter and shortening add tenderness and flavor to bread. Breads made with these ingredients are also moister. Make sure you don’t use whipped butter or margarine, or low fat products, since they contain water. The composition of the dough will be weakened, and your loaf will fail.
Eggs add richness, color, and flavor to the dough and resulting bread. Egg breads have a wonderful flavor. Sugar is the fuel that feeds yeast so it ferments, producing carbon dioxide that makes the bread rise. Some bread recipes don’t use sugar, but depend on sugars in the flour to provide food for the yeast.
Salt is essential to every bread recipe. It helps control yeast development, and prevents the bread from over rising. This contributes to good texture. Salt also adds flavor to the bread. It is possible to make salt-free breads, but other ingredients like vinegar or yogurt are added to help control the yeast growth.
Toppings can change the crust of the loaf. Egg glazes are used to attach other ingredients like nuts or seeds. An egg yolk glaze will create a shiny, golden crust. Egg white glazes make a shiny, crisp crust. For a chewy, crisp crust, spray the dough with water while it’s baking. If you brush milk on the dough before baking, the crust will be softer and tender. Brushing the baked loaf with butter will also make the crust softer. Enjoy experimenting with toppings and the recipes!
The term quick bread usually refers to a bread chemically leavened, usually with both baking powder and baking soda, and a balance of acidic ingredients and alkaline ingredients. Examples include pancakes and waffles, muffins and carrot cake, Boston brown bread, and zucchini and banana bread.(this is where today’s decorative slashing of bread loaves originates from) and taken to the communal oven to bake. These communal ovens with time evolved into the modern bakery.
The rapid expansion of steam produced during baking leavens the bread, which is as simple as it is unpredictable. The best known steam-leavened bread is the popover. Steam-leavening is unpredictable since the steam is not produced until the bread is baked.
Steam leavening happens regardless of the rising agents (baking soda, yeast, baking powder, sour dough, beaten egg whites, etc.).
This is the main factor in the rise of bread once it has been put in the oven CO2 generation, on its own, is too small to account for the rise. Heat kills bacteria or yeast at an early stage, so the CO2 generation is stopped.
Salt rising bread employs a form of bacterial leavening that does not require yeast. Although the leavening action is not always consistent, and requires close attention to the incubating conditions, this bread is making a comeback due to its unique cheese-like flavor and fine texture.[15]
Aerated bread is leavened by carbon dioxide being forced into dough under pressure. The technique is no longer in common use, but from the mid 19th to 20th centuries bread made this way was somewhat popular in the United Kingdom, made by the Aerated Bread Company and sold in its high-street tearooms.
Fats, such as butter, vegetable oils, lard, or that contained in eggs, affect the development of gluten in breads by coating and lubricating the individual strands of protein. They also help to hold the structure together. If too much fat is included in bread dough, the lubrication effect will cause the protein structures to divide. A fat content of approximately 3% by weight is the concentration that will produce the greatest leavening action. In addition to their effects on leavening, fats also serve to tenderize breads and preserve freshness.
Bread improvers are often used in producing commercial breads to reduce the time needed for rising and to improve texture and volume. Chemical substances commonly used as bread improvers include ascorbic acid, hydrochloride, sodium met bisulfate, ammonium chloride, various phosphates, amylase, and protease.
Salt is one of the most common additives used in production. In addition to enhancing flavor and restricting yeast activity, salt affects the crumb and the overall texture by stabilizing and strengthening the gluten. Some artisan bakers are foregoing early addition of salt to the dough, and are waiting until after a 20-minute “rest”. This is known as an autolyse and is done with both refined and whole-grain flours.
In wheat, phenolic compounds are mainly found in hulls in the form of insoluble bound ferulic acid where it is relevant to wheat resistance to fungal diseases.[19]
Rye bread contains phenolic acids and ferulic acid dehydrodimers.[20]
Three natural phenol glucosides, secoisolariciresinol diglucoside, p-coumaric acid glucoside and ferulic acid glucoside, can be found in commercial breads containing flaxseed.[21]
Bread can be served at any temperature; once baked, it can subsequently be toasted. It is most commonly eaten with the hands, either by itself or as a carrier for other foods. Bread can be dipped into liquids such as gravy, olive oil, or soup; it can be topped with various sweet and savory spreads, or used to make sandwiches containing myriad varieties of meats, cheeses, vegetables, and condiments.
PRESERVATION OF BREAD.
Wrap dry, crusty breads in paper. The paper will allow the crust to remain hard and the bread can breathe. Breads wrapped in paper often become stale within a day. If more than a day of preserving is needed, you can wrap the bread in plastic wrap or a plastic bag and then place the bread in a very cold, dark place, such as a cool pantry or freezer. You may need to place the bread in the oven to allow the crust to become hard again if the freezer causes it to soften. If using a plastic bag, squeeze out all of the air.
Store soft bread, such as sandwich bread, in plastic. Put it in the freezer, or a cool, dark place. Do not allow the bread to be exposed to sunlight, which can cause condensation in the wrapper, creating mold on the bread. Sliced loaves stay fresher if frozen and they thaw more quickly than unsliced loaves.
Store soft, enriched breads in a paper bag if you intend on drying the bread out to make bread crumbs. Don’t store it in plastic, or the bread will mold due to moisture and will not become hard.
Allow baked bread to cool before placing it in plastic storage. This will prevent condensation in the bag, which will stop mold from developing.
14.0 MEATS
Whether cured, smoked, fresh, or fried, it’s usually highly seasoned, thrifty cuts of meat, some of them eaten at other times of the day as well that add savory accents and substance to the breakfast plate.
TYPES OF MEATS
Bacon—the cured belly, back, or side of a pig—comes in many incarnations, from American streaky bacons and heavily smoked country styles to paprika-coated Hungarian versions. The brine-cured, loin-cut meat that Americans refer to as Canadian bacon is called back bacon in Canada and the UK and rashers in Ireland; a uniquely Canadian variation, pea meal bacon, is Cuts of bacon
Bacon joints include the following:
Sausage is another adaptable standby, from mild Irish sausage and English bangers to deeply savory American smoked sausage and breakfast links. They can be seasoned as highly as piquant Mexican chorizo or as mildly as sagey American breakfast patties. In the British Isles, blood sausage, also called black pudding, is made of pigs’ blood thickened with oatmeal or barley; in other places, such as France and Spain, bread crumbs or rice is used. White pudding, an Irish specialty, is made with pork, lard, grains, and, traditionally, brains.
Offal makes a breakfast table appearance in many countries: scrapple is a Pennsylvania Dutch pudding of pork scraps, cornmeal, and herbs. Goetta, a German equivalent popular in the Cincinnati area, combines offal and leaner cuts of pork and beef with oats. Both are sliced into patties and fried. In the American South, liver pudding is served, like other potted meats such as Spam and canned corned beef, pan-fried with eggs and potatoes or grits. Cretons, a pork pâté, is eaten on toast in Quebec and in northern Maine.
Fresh or fried cold cuts are another common theme, from German smoked sausage, chunky pork jagdwurst, and fleischwurst to Armenia’s air-dried-beef basturma and the salami-like pork roll.In the heartiest breakfasts, meat moves to the center of the plate, as in the diner classic of griddled T-bone steak with eggs or country ham steak with red-eye gravy, which counts among its ingredients another morning staple: coffee.
15.0 CEREALS
INTRODUCTION
A breakfast cereal (or just cereal) is a food made from processed grains that is often eaten with the first meal of the day. It is often eaten cold, usually mixed with milk (e.g. cow’s milk, soy milk, rice milk, almond milk), juice, water, or yogurt, and sometimes fruit, but may be eaten dry. Some companies promote their products for the health benefits from eating oat-based and high-fiber cereals. Cereals may be fortified with vitamins. Some cereals are made with high sugar content. Many breakfast cereals are produced via extrusion.
The breakfast cereal industry has gross profit margins of 40-45%, 90% penetration in some markets, and steady and continued growth throughout its history.
TYPES OF BREAKFAST CEREALS …….
Nutritionists agree that it’s important to have a healthy breakfast each morning. Cereal is a popular breakfast choice. There is a wide variety of cereals to choose from, including many healthy options and some that aren’t recommended by nutritionists due to high sugar content.
Organic Cereal
STORAGE
Breakfast cereals can become stale, develop odors, lose flavor and even develop mold if improperly stored. Storing your cereal in a proper manner can ensure crisp, fresh cereal for a longer period of time. The ‘best by’ dates are manufacturer estimates of how long the product will remain at peak quality. Most cereals will be safe to consume for a period of time longer than the recommended date. Any cereal that develops mold or a like substance should be discarded for health reasons.
16.0 DAIRY PRODUCTS
INTRODUCTION
Dairy products are generally defined as food produced from the milk of mammals (the Food Standards Agency of the United Kingdom defines dairy as “foodstuffs made from mammalian milk”). They are usually high energy-yielding food products. A production plant for the processing of milk is called a dairy or a dairy factory. Apart from breastfed infants, the human consumption of dairy products is sourced primarily from the milk of cows, yet goats, sheep, yaks, camels, and other mammals are other sources of dairy products consumed by humans. Dairy products are commonly found in European, Middle Eastern and Indian cuisine, whereas aside from Mongolian cuisine they are little-known in traditional East Asian cuisine.

CREAM
Milk, cream and other related dairy products play important roles in cooking.
This is the concentrated, fatty layer that rises to the top of un-homogenized milk. There are various terms for cream, based on its fat content:
TYPES OF CREAM
Half-and-half: This is mainly used for cups of coffee. It contains (surprise, surprise!) one half milk and one-half cream, and 10 to 12 per cent fat.
Whipping Cream: The 30% butterfat in this product allows it to thicken when whipped – but it does not end up as thick as when you whip heavy cream. (This product is mostly known in the USA and unknown elsewhere.)
Light cream: This may be used in recipes for soups and sauces, and contains 18 to 30 per cent fat.
Heavy cream (or double cream): This can be whipped. It doubles in volume when whipped and has 36 to 40 per cent fat.
Sour cream is popular as a topping for baked potato or soups, and as the base for many dips. It is also used in baking recipes, such as Chocolate Cake. Sour cream is made by adding lactic acid to cream. It contains 18 per cent fat, but also comes in low and non-fat (thickened with stabilizers) versions. Plain yogurt can often be used as a substitute for sour cream.
This British invention is integral to the tradition of “afternoon tea,” used as a spread on scones (along with jam.)
Clotted cream is made by heating unpasteurized milk and skimming off the surface layer (which is the clotted cream.)
This French delicacy is a thickened, soured cream that’s often used as a fruit or dessert topping, or as a topping for soup. It has about 28 per cent fat, and is traditionally made with unpasteurized milk. In the U.S., it’s quite expensive.
According to Epicurious, you can make crème fraiche at home by mixing one cup of whipping cream with two tablespoons of buttermilk in a glass container. Let the mixture stand at room temperature for 8 to 24 hours, or until thick. Stir, cover and refrigerate for up to 10 days.
The “whole” in whole milk refers to the fact that it contains the natural 3.5 per cent fat content of cow’s milk. Most milk bought in shops has been pasteurized – heated and then quickly cooled – to kill bacteria, and homogenized so that the cream (milk fat or butterfat) does not separate and rise to the top.
Whole milk is recommended for babies and young children, whose growing bodies need the full fat content. For those of us who aren’t growing (or don’t want to!) there are three common varieties available that are lower in fat: one that contains two-per-cent fat and another that contains 1 per cent. Skim milk contains less than half a per cent of fat.
Milk is available in several varieties:
Lactose-free: This milk has a reduced amount of lactose (the sugar found in milk) for those who are allergic.
Low-Sodium milk: Milk has a naturally high volume of sodium. This milk is for those who are on sodium-restricted diets.
Dry milk: Powdered milk (skim, whole or buttermilk) can be mixed with water to drink or use in recipes. It doesn’t taste quite like fresh milk, though.
Buttermilk came into use as a byproduct of the butter-churning process: Rather than waste the residual liquid, people began to use it in baked goods, soups, dressings and sauces.
Nowadays, buttermilk is made by adding bacteria to milk (often skim milk) to give it a thicker texture and a tangy, yogurt-like flavor. Despite its rich-sounding name, buttermilk is actually lower in calories and fat than regular milk.
In recipes, it can often be substituted in equal proportions for plain yogurt (and vice versa). It can also be used in startcooking.com’s Avocado Soup. Occasional users of buttermilk may want to buy it in powdered form rather than fresh — that way you won’t end up wasting most of the carton when you only needed a cup.
This is canned milk that has had about 6o per cent of the water removed. Because has a long shelf life, it became popular as a milk substitute before refrigeration. These days, it’s mostly used to add creaminess to desserts. If it’s mixed with an equal proportion of water, it can be used to substitute milk.
Evaporated milk is available in whole, low-fat and skim versions. It can also be used to add creaminess to sauces and soups. In Holland, evaporated milk is widely used as a coffee creamer. We use is here at startcooking.com to make Stove-Top Mac and Cheese.
Evaporated milk is not to be confused with sweetened condensed milk (see below), which comes in similar cans.
Evaporated Milk and Sweetened Condensed Milk
This sticky, sweet canned concoction is made with a mix of whole milk and sugar. It’s made by heating the milk and sugar together, which causes the water to evaporate. It’s used mainly in pie fillings (Key Lime Pie, for example), cakes and other desserts. In some countries – particulary Vietnam – sweetened condensed milk is used to flavor coffee.
Startcooking.com uses sweetened condensed milk for Chocolate Fudge, Holiday Cookies, and Pumpkin Pie for Beginners.
Often sold next to cow’s milk in North American grocery stores, soy milk is made from pressed soy beans and water. It has a slight bean taste. Soy milk is the basis of tofu, and is used widely in Asia for both drinking and cooking. It has a similar nutritional breakdown to cow’s milk, but is typically fortified with calcium. It provides an alternative for anyone with lactose or casein (milk protein) allergies. Soy milk comes in 2 per cent fat, and lower fat varieties, natural, sweetened and flavored.
This one does NOT come from a cow. Coconut “milk” is actually the liquid produced from squeezing grated coconut meat, not the liquid that’s sitting inside the coconut. Coconut milk is often used in Thai or Asian curries and soups, as well as sweets and desserts.
Sold in cans, coconut milk has about 17 per cent fat content. It is available in lower-fat versions,
Cheese is a generic term for a diverse group of milk-based food products. Cheese is produced in wide-ranging flavors, textures, and forms.
Cheese consists of proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. It is produced by coagulation of the milk protein casein. Typically, the milk is acidified and addition of the enzyme rennet causes coagulation. The solids are separated and pressed into final form.[1] Some cheeses have molds on the rind or throughout. Most cheeses melt at cooking temperature.
Hundreds of types of cheese from various countries are produced. Their styles, textures and flavors depend on the origin of the milk (including the animal’s diet), whether they have been pasteurized, the butterfat content, the bacteria and mold, the processing, and aging. Herbs, spices, or wood smoke may be used as flavoring agents. The yellow to red color of many cheeses, such as Red Leicester, is normally formed from adding annatto.
For a few cheeses, the milk is curdled by adding acids such as vinegar or lemon juice. Most cheeses are acidified to a lesser degree by bacteria, which turn milk sugars into lactic acid, then the addition of rennet completes the curdling. Vegetarian alternatives to rennet are available; most are produced by fermentation of the fungus Mucor miehei, but others have been extracted from various species of the Cynara thistle family.
Cheese is valued for its portability, long life, and high content of fat, protein, calcium, and phosphorus. Cheese is more compact and has a longer shelf life than milk, although how long a cheese will keep may depend on the type of cheese; labels on packets of cheese often claim that a cheese should be consumed within three to five days of opening. Generally speaking, hard cheeses last longer than soft cheeses, such as Brie or goat’s milk cheese. Cheese makers near a dairy region may benefit from fresher, lower-priced milk, and lower shipping costs. The long storage life of some cheese, especially if it is encased in a protective rind, allows selling when markets are favorable. Additional ingredients may be added to some cheeses, such as black peppers, garlic, chives or cranberries.
A specialist seller of cheese is sometimes known as a cheese monger. To become an expert in this field, like wine or cooking, requires some formal education and years of tasting and hands-on experience. This position is typically responsible for all aspects of the cheese inventory; selecting the cheese menu, purchasing, receiving, storage, and ripening.
CULINARY THEORY 3
INTRODUCTION
Catering systems are complex sociotechnical organizations involving both people and machinery in the production and service of food. Such systems have the key purpose of transforming a diverse combination of ‘inputs’ into desired ‘outputs.’ Systems need to maximize their interdependence with the environment within which they exist. The objective for the management of any system is to find ways of ensuring its long-term survival and growth, often by seeking gains in efficiency and effectiveness in producing its outputs. Different types of catering systems have evolved in recent years as a result of efforts to achieve these goals. These developments have brought with them further technological challenges related to the provision of safe, nutritious, quality food products.
EMERGENCE OF CATERING SYSTEMS
It has been noted that the ‘systems’ approach to management involves viewing organizations ‘holistically’ in order to gain a better insight into these complex situations, rather than merely focusing on individual parts or problems. Systems theory has been applied to a wide range of organizational contexts and has proven valuable in solving problems particularly where the situation is unpredictable and issues causing concern are ill defined or vague. It has been suggested that ‘systems’ terminology was first applied to food production and service operations during the 1950s. The terms ‘catering systems,’ in common use in the UK, and ‘food service system,’ more frequently used in the USA, can be said to have been coined as a result of the ‘systems approach’ being applied to those operations that undertook the production of food and its service to consumers.
A simple definition of the term ‘catering system’ that has been proposed is that it refers to ‘a particular method of organizing the production and service of food.’ It is contended that the application of a systems approach involves defining and describing food production and service operations using ‘systems concepts.’ This enables the component parts, or subsystems, of an operation to be identified and the efficiency of their interaction assessed. Undertaking such a ‘systems analysis’ facilitates the application of ‘problem-solving’ methodologies, which can generate design solutions for the optimization of system performance. Utilization of these techniques, and awareness of the nature of organizations as being complex groups of ‘subsystems’ that need to be monitored and modified according to how efficiently they fulfil their specified objectives, can hence be referred to as ‘systems management.’
Catering systems may be described as systems that have objectives relating to the production and/or service of food products to specified groups of consumers. Such systems normally receive a combination of inputs, which include:
The inputs form the components of a complex set of ‘subsystems’ that act to produce outputs required by the environment within which the system exists. The activity of the subsystems must be ‘managed’ effectively to ensure that they exhibit unity of purpose and exploit potential synergies within the system. The broad aim of any system is to fulfill demand for its outputs with maximum efficiency on a continuous basis. Through effective management that takes account of feedback from the market and environment, and also of ‘feed-forward’ from the manager’s knowledge and experience of similar operations, the system’s continued existence and growth are ensured.
Different views have been put forward by management and systems theorists over the years about the most important focus for managers of sociotechnical systems. In essence, these contentions may be summarized as follows:
The long-term survival of a system will depend on how well it ‘interacts’ with its environment, that is to say, how efficiently it acquires appropriate inputs and how ideally the output it produces match the current and potential demands of the environment. The efficiency with which a system works, and therefore thrives, will depend on ensuring that its subsystems work harmoniously towards common goals that contribute to, and are congruent with, the objective/s of the organization. Catering systems, therefore, have been defined either in terms of the markets that they serve, that is against the context of their environment, or in terms of the differentiation in their internal processes or subsystems. There follows a brief summary of the classifications that can be applied to catering systems in relation to these perspectives.
Catering organizations, as with all ‘systems,’ interact with their environment. In an ideal world, a catering system will produce the exact outputs the ‘environment’ demands in terms of both quantitative and qualitative requirements. A key task in managing such systems involves matching systems output to the requirements of the environment in such a way as to maximize the systems potential to do work. Thus, catering systems have typically been classified in terms of the sector of the environment they serve. The two major sectors into which catering systems are divided are the ‘Cost Sector,’ which, broadly speaking, incorporates all not-for-profit catering activities, and the ‘Profit Sector,’ which includes all profit-orientated organizations.
The ‘Cost Sector’ typically includes all catering systems in the following subsectors:
In 1996, the value of purchases (which equate with sales) in this sector, in the UK, was almost £1.5 billion, ‘Healthcare’, ‘Education,’ and ‘Business and Industry’ sectors each having similar values of £460–475 million. The ‘Profit Sector’ includes catering systems in the subsectors listed below:
In 1996, the value of purchases in the profit sector was over £6 billion, and sales were in excess of £18 billion. The Hotel sector alone accounted for £4.7 billion sales, with Public Houses being the second largest subsector having sales just less than £4 billion. These figures serve to confirm the economic importance of catering systems to the UK economy, which reflects a global pattern in the developed world.
Catering Systems Defined by Their Sub systemic Differentiation
Catering systems may be defined in terms of the differences in the subsystems they contain. Subsystems can be defined in many ways, depending on the analysis being undertaken. In the example of ‘process subsystems’ alone, the possible permutations that can be identified mean that there are potentially innumerable variations in operational systems. Attempts have been made to resolve these variations into viable ‘generic’ groups. There are essentially three major classifications of catering systems into which the minor ‘generic’ variations may all be fitted. These can be summarized as follows:
‘Cook–serve’/Integratedfood-servicesystems, where both the preparation of food and its service are an integral function carried out in a single operation, and there is little delay between preparation and food service. The majority of the catering industry still operates conventional systems of this kind. Food-manufacturing systems, where the production of food and meals is separated or ‘decoupled’ from the service of meals. Such systems encompass the use of chilling and freezing methods to preserve the food and in the past have been referred to as ‘technological catering systems.’ Meals-assembly/food-delivery systems, a recent systems development, in which little or no actual food preparation takes place in the system and the operation focuses on the assembly, regeneration, and service of meal.
COOK–SERVE CATERING SYSTEMS
The cook–serve or integrated catering system represents the conventional approach to catering. These systems operate over a short time scale with the minimum feasible period or ‘time buffer’ between cooking and food service. Where food is cooked to order, or produced in small batches to suit expected demand, it is quite easy to minimize the ‘time buffer,’ but this can be more difficult where food is made in bulk quantities for large numbers such as in institutional food services. The period, over which food is held hot, which, according to UK legislation, must be at a temperature above 63 oC, is largely dictated by the logistics of serving individual customers in each situation.
In cook–serve systems, should food need to be held hot for any appreciable period, time- and temperature- dependent changes occur that reduce both the sensory and nutritional properties of food. Adverse sensory changes can affect the color, texture, and flavor of foods. Losses in heat-labile vitamins such as thiamin and vitamin C also occur. In research, the loss of vitamin C (as measured using the ‘Fluorimetric method’) has frequently been used as an indicator of food quality, as its destruction is time- and temperature-dependent and is accompanied by losses in sensory qualities.
Extended cooking times and hot holding period cause substantial losses not only in cook–serve systems but also in the other systems discussed. It can be imputed that cook–serve systems in many areas of catering have their limitations. This is particularly the case in large-scale institutional catering such as in the healthcare sector. Large hospital food service operations formerly using traditional cook–serve methods and experiencing associated quality problems owing to extended hot holding before service have been at the forefront of the change to food-manufacturing and delivery systems.
FOOD-MANUFACTURING SYSTEMS
Food-manufacturing systems avoid prolonged hot holding of foods as they incorporate a substantial ‘time buffer’ between cooking and food service. This is achieved by chilling or freezing the prepared meals followed by appropriate storage. In this case, a ‘time buffer’ is effectively used to ‘decouple’ the production subsystems of the operation from food assembly and service.
In food-manufacturing systems, food items are prepared in quantity in a large kitchen or centralized production unit, then chilled or frozen usually in multiportion packs, in effect preserving food until required. Products can be regenerated in the required amounts in a satellite kitchen, or using specialized reheating equipment close to the point of service (e.g., in large institutional operations) or within individual units (e.g., in an aeroplane’s galley kitchen in in-flight catering). This approach minimizes the time food is actually hot-held as it should take only the time required to serve food to customers immediately after regeneration, which will minimize potential deterioration.
MEALS-ASSEMBLY/FOOD-DELIVERY SYSTEMS
Food-delivery systems take the concept of ‘decoupling’ to a logical conclusion in that the manufacturing subsystems are completely removed. Food products are ‘bought in’ from specialist manufacturers producing frozen menu items for assembly and regeneration in simple kitchens consisting essentially of reheating equipment, or close to the consumer using specially designed heated trolleys. These catering systems, which do not require the traditional kitchen, may be referred to more aptly as ‘meals assembly systems’ as they only consist of the storage, assembly, regeneration, and service subsystems.
The length of the ‘time buffer’ in these systems is determined by the preservation technique used, being up to 5 days for standard chilled foods and a year for frozen foods. Thus, the time buffer decouples production from service and potentially preserves food quality. This potential can be lost if the food is subjected to another period of hot holding after regeneration. UK guidelines recommend that it should take no longer than 15 min for meals to be served after regeneration is complete. Whilst the food-manufacturing approach aims to improve efficiency by decoupling the major subsystems, ‘meals assembly’ actually simplifies a catering system by removing the preparation and cooking subsystems completely. This allows the caterer to focus on food service and the monitoring of food safety and quality.
Preservation Methods in Food-manufacturing and Meals-assembly Catering Systems
Cook–Freeze
Freezing is a reliable method of preservation as it includes the barrier of the latent heat plateau seen in any time/temperature graph during the thawing of frozen food. This phase change provides a safety factor against temperature abuse, although any partially thawed foods at the surface could potentially cause food-safety and sensory problems. A variation of this is the cook–freeze–thaw system introduced because, once thawed, the food can be treated as for cook–chill. However, the system can be potentially hazardous unless the temperatures are tightly controlled.
Cook–Chill
Cook–chill systems have gained acceptance through consumer preference for minimally processed foods. These are, however, more susceptible to temperature abuse in only having a small barrier to temperature change. Precise temperature control is necessary throughout the whole system.
Sous Vide
Sous vide is a specialist form of cook–chill system in which product shelf-life is extended from the normal 5 days up to as long as 42 days. Sous vide cooking is semi continuous when operated on a large scale but discontinuous in smaller operations. There are particular concerns that all systems employing this method must have appropriate technical expertise to ensure that all the processing equipment and operating procedures are adequately designed so that products receive sufficient heat treatment.
Questions about food safety and quality in sous vide operations have been raised. Food is cooked in sealed plastic bags under a partial vacuum, which slows the rate of heat transfer and could result in underprocessing. This has led to concerns that psychrotrophic pathogens, such as Listeria monocytogenes, Yersinia enterocolitica, Clostridium botulinum, and the like could survive. The most hazardous of these is Clostridium botulinum, some strains of which produce a toxin at temperatures as low as 3.3 degrees C. Although the vegetative cells of Clostridium botulinum are destroyed by heat treatment of not less than 70 degrees C for 2 min at the coldest spot, foods should be heated to 90 degrees C for 10 min to ensure destruction of spores.
Concerns about the safety of vacuum-packaged and modified atmosphere-packaged products have led the Advisory Committee on the Microbiological Safety of Food in the UK to issue a Code of Practice that recommends the use of additional hurdles and the application of the HACCP technique in the manufacture of all such products. The retention of most of the original juices within the package after cooking has led to claims that sous vide processed foods have enhanced sensory qualities. This claim has not been fully supported by research findings to date.
Further Developments in Cook–Chill
As there is doubt that chilled storage alone can assure the safety of sous vide products, recent work has focused on the formulation of products with additional hurdles. This involves the combination of several factors together, which collectively ensure the microbial safety of food, even though each hurdle on its own might be insufficient to maintain safe food. Examples of hurdles are low water activity, low pH, use of modified atmospheres, irradiation, added organic acids and protective cultures. The incorporation of such adjuncts provides hurdles to microbial growth and can also impact positively on safety, nutritional, and sensory aspects. Research indicates that cook–chill produces a product that is inferior in sensory qualities to that produced in cook–serve systems in ideal conditions, but better than that produced in the no ideal or abused situations often found in catering systems.
Meals-Assembly Techniques
In this type of system, menu items are prepared and processed by food manufacturers to a specification prepared by a caterer. Typically, these menu items will include main courses, vegetables, and puddings, plus accompaniments such as sauces. The meals are chilled or frozen, and packaged in bulk foil containers suitable for use in commercial catering operations. After delivery to the catering unit, food is stored appropriately until requisitioned. Meals are then assembled, regenerated usually using forced-air convection ovens, and served. Meals assembly represents a radical change in catering systems. By the year 2000, such systems were being used by almost a fifth of UK NHS hospitals as well being more widely adopted within the profit sector, particularly by pub and fast-food operations.
This type of system has proven popular in healthcare catering, because it offers cost savings by reducing the need for skilled labor and expensive plant and equipment. The meals-assembly system allows the catering manager to concentrate on food-service techniques and monitoring methods, in particular to control time and temperature factors. A quality-management approach is essential for both the manager’s own operation and for their suppliers, the food manufacturers. The final quality of food produced using these new systems are governed by the control of time–temperature parameters throughout the system. Potentially, regeneration is the stage that can affect food quality most adversely, as primary cooking is common to all.
Regeneration
In a meals-assembly system, regeneration usually involves a standard reheat cycle in which a mixed load of chilled or frozen meals is regenerated in a specially designed oven. This means that food can be under- or over-heated as different foods have different thermal characteristics. Owing to food-safety concerns food, is often effectively overheated, with core food temperatures at the end of regeneration in excess of 80oC being usual. The time spent at this temperature level is particularly detrimental to food quality, causing both heat-labile vitamin losses and sensory losses. There is often potential to reduce the severity of the regeneration process whilst still maintaining safety, yet preserving sensory and nutritional quality, but reliable control and monitoring methods are vital.
Various types of equipment can be used for regenerating assembled meals, the most common currently being forced-air convection ovens. Forced-air convection technology gives a fast regeneration time owing to constant air velocity and even temperature distribution. Hot-air convection currents being forced to circulate the oven cavity by a fan achieve this. These currents remove the steam layer from the surface of the food quickly and enable heat to reach the food directly, thus causing a rapid rise in temperature. The heating effect can be enhanced further by the incorporation of steam injection into the oven cavity. The latent heating effect of condensing steam on the surface of the food package promotes faster reheating.
The use of microwaves in regeneration is less common but can be successfully combined with forced-air convection technology. Microwaves alone are better for reheating chilled, rather than frozen, foods because of the different absorbency of microwaves by ice and water, which can cause thermal runaway, and leading to hot spots and cold spots in the product. This can still occur in chilled products because of different dielectric properties in foods of varying compositions. The newer systems of food manufacture and food delivery require strict control throughout heat processing to ensure food safety and maintain consistent quality. New approaches to equipment design include the application of computational fluid dynamics and the use of model-based control design.
FOOD-SAFETY ISSUES IN CATERING SYSTEMS
Temperature control in catering systems is imperative, and monitoring systems have consequently been developed in recent years. Larger units can have computer-controlled temperature-monitoring devices, whereas smaller operators generally rely on making manual checks and keeping manual records. Failure to control time and temperature remains a problem responsible for the majority of food poisoning cases caused by the catering industry. In the UK, there is a mandatory requirement for caterers to identify the steps in the system where hazards can arise and put appropriate control and monitoring measures in place. This relates to the implementation of Hazard Analysis Critical Control Point (HACCP) techniques. Caterers are encouraged to develop modified HACCP approaches based on the Assured Safe Catering methods, but this is expected to be a slow process that will take place over several years.
There is a need to address the safety of individual foods as caterers continue to cause outbreaks of food poisoning owing to the use of contaminated fresh shell eggs. The UK Government has recommended that caterers should make use of heat-treated egg products, pasteurized to eliminate Salmonella enteritidis. Systems used in the catering industry can be seen as a continuum of the techniques used in the food manufacturing industry and therefore can employ similar methods of control. For example, the concept of quality management can be usefully applied. As more food-manufacturing techniques are adopted, and encouraged by regulatory authorities, these techniques should accompany the HACCP approach so that safety and quality issues are both addressed.
CATERING SYSTEMS IN CONCLUSION
There is a need for further research to confirm claims of improved sensory qualities, safety, and nutritional values in food manufacturing and meals assembly systems. Quality changes can occur rapidly, but many variables affect the end result that is often product-specific. The lack of control and standardization in both the catering industry and experimental methods makes comparisons between studies difficult. The fact that technological innovations in catering systems have not introduced new methods of food production but rather, as some have noted, introduced systems of food preservation has not been proven to have had a positive impact on food quality predicted, as a matter of course.
Generally cook–serve catering systems still predominate throughout the food-service industry. It has been found that increased size, certainly in the healthcare sector, tends to dictate whether or not food-manufacturing systems have been adopted. However, recent surveys have indicated that around three-quarters of hospitals in the USA and almost the same proportion in the UK still operate conventional food-service systems.
In recent years, the emergence of food-delivery/meals-assembly systems has offered the opportunity for many smaller catering operations to adopt this type of system. Whilst this development means that catering systems can provide a wider menu with less skilled staff and reduced equipment needs, it has been observed that quality suffers if regeneration of products is poorly controlled and if the aesthetics of meals assembly and customer service expectations are overlooked. It is pertinent to recall that the term ‘catering system’ emerged from the application of systems theory to the management of food-service operations. It should not be forgotten, therefore, that the systems approach is ‘holistic,’ and that any innovation that affects one or more subsystems will also affect the rest of the system, its inputs, and the efficiency and effectiveness with which it produces its outputs.
IN-FLIGHT CATERING
An airline meal or in-flight meal is a meal served to passengers on board a commercial airliner. These meals are prepared by airline catering services.
The first kitchens preparing meals in-flight were established by United Airlines in 1936.These meals vary widely in quality and quantity across different airline companies and classes of travel. They range from a simple beverage in short-haul economy class to a seven-course gourmet meal in long-haul first class.
The type of food varies depending upon the airline company and class of travel. Meals may be served on one tray or in multiple courses with no tray and with a tablecloth, metal cutlery, and glassware (generally in first and business classes).
The airline dinner typically includes meat (most commonly chicken or beef) or fish, a salad or vegetable, a small bread roll, and a dessert.
Caterers usually produce alternative meals for passengers with restrictive diets. These must usually be ordered in advance, sometimes when buying the ticket. Some of the more common examples include:
Condiments (typically salt, pepper, and sugar) are supplied in small sachets. For cleanliness most meals come with a napkin and a moist towelette. First and business class passengers are often provided with hot towels and actual salt and pepper shakers.
During morning flights a cooked breakfast or smaller continental-style may be served. On long haul flights and (short/medium haul flights within Asia) breakfast normally includes an entrée of pancakes or eggs, traditional fried breakfast foods such as sausages and grilled tomatoes, and often muffins or pastry, fruits and breakfast cereal on the side. On shorter flights a continental-style breakfast, generally including a miniature box of breakfast cereal, fruits and either a muffin, pastry, or bagel. Coffee and tea are offered as well, and sometimes hot chocolate.
Food on board the flight ranges in price from free (typically on full-service European and Asian airlines, and on almost all long distance flights) to as much as ten dollars on low-cost airlines. Quality may also fluctuate due to shifts in the economics of the airline industry, with private jet passengers receiving the equivalent of five-star food service.
On the longest flights in first class and business class, most Asian and European airlines serve multicourse gourmet meals, while airlines based in the US tend to serve large, hearty, meals including a salad, steak or chicken, potatoes, and ice cream. Some long-haul flights in first and business class offer such delicacies as caviar, champagne, and sorbet. The cost and availability of meals on US airlines has changed considerably in recent years, as financial pressures have inspired some airlines to either begin charging for meals or abandon them altogether in favor of small snacks (Southwest Airlines). Eliminating free pretzels saved Northwest $2 million annually. The carrier lost nearly $3.3 billion since 2001. Air China has reported that each domestic flight’s meal requires RMB50 (US$7.3) while international flights require RMB70 (US$10).[5] However, this figure varies from airline to airline, as some have reported costs to be as low as US$3.5.[6] Air China is also minimizing costs by loading only 95% of all meals to reduce leftovers and storing non-perishable foods for emergencies.
Meals must generally be frozen and heated on the ground before takeoff, rather than prepared fresh. Guillaume de Syon, a history professor at Albright College who wrote about the history of airline meals, said that the higher altitudes alter the taste of the food and the function of the taste buds; according to de Syon the food may taste “dry and flavorless” as a result of the pressurization and passengers, feeling thirsty due to pressurization, many drink alcohol when they ought to drink water.
Food safety is paramount in the airline catering industry. A case of mass food poisoning amongst the passengers on an airliner could have disastrous consequences. For example, on February 20, 1992, shrimp tainted with cholera was served on airlines Argentines’ Flight 386. An elderly passenger died and other passengers fell ill. For this reason catering firms and airlines have worked together to provide a set of industry guidelines specific to the needs of airline catering. The World Food Safety Guidelines for Airline Catering Revision 3 is offered free of charge by the International Flight Service Association.
Resources are needed for the selection, purchase and storage of food. A caterer must consider the best use of these resources to produce the best results. This unit will expose you to the many resources that you require for efficient selection, purchase and storage of food in your establishment. It will also expose you to the many techniques you need in the market place and the various ways in which you can store your equipment and food to avoid waste. It will also show you how to deal with advertisements to get the best results.
Selection or choice of food is very important in meal management. Providing food in a manner which is satisfactory to many people can be a complicated issue. Many decisions are required and careful thought and planning is important.
FOOD SELECTION
The types of food you select depend on:
The more money you have the more foods you can buy and the greater your choice. People who have a lot of money can afford a variety of meals and can eat away from home. People with small incomes have a limited choice and it becomes a hard task to buy enough food to meet family needs.
If you have a limited food budget, you can save money by buying foods that in season and buying cheaper cuts of meat as well as comparing prices in different shops.
You eat to keep alive and healthy. At the same time most people also eat to enjoy the food. People tend to eat foods they like and avoid those they dislike.
Is there any food you dislike? Why do you dislike it? Is this food very nutritious?
Foods are normally disliked because:-
Of their color, flavor and texture They are new and have never been tried They do not look attractive The food is associated with some ill feeling The way it is cooked is not appealing
Food is enjoyed when it is liked. Food is enjoyed because it provides some sensations for you the aromas and flavors that come from food are detected by special nerves in the sense organs of taste and smell. Sight and temperature also have a great effect on the enjoyment of food. Cooking food often develops the flavor and changes the texture of food. Many foods are traditionally eaten hot or cold. If food is too hot or too cold it true flavor may be masked and it may be uncomfortable to eat.
Another great influence on food choice is advertisement. Advertisements have a way of persuading people to make choices. Food manufacturers and shops advertise their products through television, radio, magazines, newspapers, posters and leaflets.
Good adverts are decent, honest and truthful.
They do not mislead the public about a product.
They show a sense of responsibility to people.
They conform to fair competition behavior different manufacturers and businesses.
Your food choice will also depend on your need for food. Everyone has a biological need for food. It is essential for life without food one becomes weak and ill. People vary in the amount of food they need for reasons like health, age and activity.
Your choice of food will therefore depend on each of these factors. Your nutrition knowledge helps you to choose food that provides the necessary nutrients to meet your needs.
Food purchasing can be a boring or interesting adventure depending on one’s approach to it. To make food purchasing interesting you have to know much about the market place and ways in which you can make the most out of your food budget.
First of all you need to know the factors that determine the cost of the things you want to purchase. Production cost, the season, the market supply of the goods, the demand of the goods, Advertisements, Amount of processing
Factors affecting purchasing;
This is the amount of money used to produce the item. In the case of food, the production cost will include the money spent on cleaning the land, sowing the seeds, harvesting and processing. The final cost of a product is determined by this amount plus others like transportation cost, profit and handling charges.
Seasonal differences in the cost of food occur frequently in Ghana. Food items always cost less when they are in season because they are plenty and so the supply becomes high. When market supply of a commodity becomes high the price of the commodity falls. Food items that are out of season become scarce and therefore their prices are higher.
Usually when many people want a certain item, its price increases.
These are ways in which manufacturers and sellers tell us they have certain goods and services for sale. Advertisements cost money. The cost of advertising a product is added to the production cost to make up the price of a product. The more the advertisement the higher the cost of the product.
Processing adds value to products and it costs money. Foods that are processed to provide conveniences cost more than unprocessed ones.
For most people food budget is one of the largest expenses. Careful planning and shopping can result in substantial savings. Normally if you are rich you tend to spend more money on food and if you are poor you spend less.
Foods are sold in many forms. The form you buy is determined by the storage facilities you have, how much convenience you need and what you want to use the food for. Foods are sold fresh, dried, frozen or canned.
Fresh foods provide most nutrients since processing may destroy the nutrients. Fresh foods are natural and do not require fortification or processing. They therefore cost less. However, because they are fresh they spoil fast.
Frozen foods are much nearer to fresh foods as far as nutrient content is concerned. Freezing prevents the action of enzymes and microorganisms. Microorganisms are minute organisms which we cannot see but which can be very harmful to us and can spoil our food. Frozen foods must be stored in the freezer in useable quantities. Remember that when you thaw a frozen food completely it must be used immediately to avoid spoilage. Thawed foods should not be refrozen.
Dried foods have their moisture removed. Some dried foods like milk powder, can be reconstituted by adding water. Dried foods do not require refrigeration. They are light in weight and take up les storage space.
Canned foods are convenient to use. They will not spoil as long as the can is not punched. Canned foods should be stored in cool dry places. They do not have the taste of freshly cooked foods. They are much more expensive than foods in other forms. They have long shelf life that is they last longer. Unless canned foods are fortified with nutrients they loose most of their nutrient content.
Do not buy processed foods when the following signs are seen:-
Some unscrupulous sellers buy products which have expired from the large shops and sell then in the open markets at prices that are cheaper. Check the expiration dates and shapes of such items before you buy them.
High quality fruits and vegetables are the ones that are ripe, crisp, fine and free from bruises. Nutrients values of fruits and vegetables decrease over a period therefore you should try to buy those that are fresh. Vegetables will usually wither when kept in the sun or kept for too long.
These foods form the staple food in many Ghanaian homes. They are relatively cheap but do not have good keeping quality. They can be used for a variety of food products. They are sold in fresh or dried and powdered forms. Examples of such foods are plantain cassava, yam, cocoyam, water yam, potato and taro. When purchasing these foods care must be taken so that only good quality foods are bought. Roots should be free from bruises since this would make them rot quickly. They must be firm to touch. Softness in roots is a sign of spoilage. They must not start sprouting. Ripped plantain should not have black spots on the skin.
Foods in this group are very expensive and they spoil very quickly. The most expensive animal foods are not necessarily the most nutritious. If you have limited resource you can still get good quality protein from cheap sources such as snails, crabs, sprats and anchovies. Bone in beef is just as nutritious as bone less beef. When buying animal foods, quality and safety are very important consideration. You can tell the quality of animal products as follows: – Meat should have a deep red color with white or creamy fat. Signs of poor quality are very dark brown or green color and yellow fat. When the meat is greenish and smells bad it is of poor quality and not safe for eating. Poultry should have a meaty body with meaty legs and breasts. The skin should not have any discoloration Fish should have firm flesh and shiny skin with a lot of tightly clinging scales. It must have bright and clear eyes and red shiny gills. Disagreeable color, flesh that leaves a dent when pressed and dries skin is signs of spoilage.
Before I leave this topic, let me add that tenderness of meat and poultry depend on the age of the animal and the part of animal bought. The nutritive value is, however, not affected by these.
Eggs may have white or brown shells. The nutritive value is the same. Eggs can be bought fresh or dried.
When buying eggs, look for shells that are rough and not shiny. Test for freshness by putting it in a jar of salt water. When it floats the eggs is stale. Buy eggs that are clean and not cracked.
Milk is sold in liquid or powdered form. Your choice will depend on what you want to use it for and the storage facility you have. Milk can be bought fresh. Its keeping quality is not good especially outside the refrigerator. When milk tin is opened and used the remaining milk should be poured out of the tin and kept in the refrigerator or a cool dry place, well covered.
Legumes include groundnuts, cowpeas and soya beans. Legumes are sold shelled or unshelled. They are sold dry or canned. When buying legumes you must buy the ones that are not infested with weevils. Also they must not be mouldy. It is better to make your own groundnut paste than to buy from the market. Often groundnut paste is adulterated before it is sold in the market.
Cereals are normally sold in grains or in powdered form or as breakfast cereal.
When buying cereals avoid the ones that have weevils or have grown moulds. Mouldy cereals are not good for consumption. Make your own corn dough instead of buying from the market.
Food commodities that are purchased from the market must be stored well if they must keep their quality. As soon as you return from the market you need to group your item into the following categories.
Food is stored mostly because we want to keep it safe and prolong its shelf life. There are three types of food storage. These are:-
Foods that need to be kept dry are usually stored in cabinets or store rooms. Cereals, canned foods packaged foods and other dry food items should be kept in cool dry and clean places in the kitchen. Food should not be stored above refrigerator or cooker or near any heat outlet. The temperatures of these areas are warm and favorable for the growth of microorganisms. Storage areas must be kept clean so, you should wipe spills as soon as they occur to avoid attracting insects.
Refrigerator temperatures should be between O degrees C and 7degrees C. Temperatures in the refrigerator vary depending on the part of the refrigerator. The shelves on the door are not as cold as the inside. This area is good for storing eggs. The lower part of the refrigerator is also not very cold so vegetables can be stored there. Foods stored in the refrigerator must be covered well so that it would not dry out or absorb odors from other foods.
The temperature of the freezer should be – 18 degrees C or below. Frozen foods their original packages in the freezer. Foods to be frozen should be wrapped in moisture and vapors proof wrapping and arranged properly in the freezer.
After shopping for food, store frozen foods immediately in the freezer, so that they will not thaw completely. After this you can store other foods that need refrigeration like eggs. Wash fresh vegetables before storing in the vegetable compartment of the refrigerator. Store yams, potatoes and onions in a cool dry place.
If fruits are not fully ripe they should be kept at room temperature until they are ripe. Then they can be put in the refrigerator. Do not store bananas in the refrigerator because they darken and do not look attractive.
Canned and packaged foods should be placed in a cool and dry cupboard. When opened they must be refrigerated.
FOOD COST CONTROL
Food costs are probably one of the topics most discussed by Caterers and yet it is the one they usually understand the least. We all know we must control costs, but in order to control them we must also be able to measure them effectively. When faced with a food cost problem, many operators try the quick fix of raising prices to offset high costs or reducing prices to increase business volume. In reality this can be counter-productive and actually decrease sales and profit margins. Knee jerk reactions are not appropriate for resolving these issues.
The reason we are in business is the bottom line, of course – making a profit. In order to do so, you must set up operational procedures that will allow you to know and control your food costs.
Ø Standardize your Recipes
The first step is to establish standard recipes for all menu items, including specials. This will give you an accurate picture of what your cost on every item should be – your potential food cost. In fact, just the act of developing standard recipes will give you tremendous insight – you will know more about your operation than you ever did before!
A standard recipe should be developed for every item with more than two ingredients. It should detail all ingredients in the dish as well as a basic cooking and plating procedure. It will tell you if the item can be sold at a profit within your market position and what that profit should be.
Ø Establish Purchase Specifications
The next step in controlling food costs is to establish purchase specifications. These will be determined by what’s on the menu, the standard recipe for each item, production or batch sizes, what’s available in the market and storage capacity. The purchase specification should detail the name of the product, the unit of purchase (pounds, litres, case, dozen, etc.), grade if applicable, appearance, temperature at delivery, type of packaging and any other information that will assist in evaluating the product once it is received.
The control of purchasing is critical to maintaining profitability. You must determine if stock holding is at the proper level. Large levels lead to increased spoilage, shrinkage due to pilfering and higher storage costs. That’s why it’s so important to establish a par stock level that is strictly followed.
Make sure suppliers have copies of the purchase specifications. If you regularly find yourself running low on certain items and sending staff out to purchase these items at retail, you know you’re incurring unnecessary costs. Purchase specifications will help alleviate this problem and allow you to take advantage of lower seasonal prices on a variety of products.
Seek competitive bids on high cost items. Finally, purchase these items in the smallest practical unit size.
A purchase specification should include all important aspects of the product being purchased. This way, your supplier will be certain of the product you are looking for and your receiver will know exactly what to expect.
Sample Purchase Specification
Ø Standardize your Portions
Once you have implemented standard recipes and purchase specifications, the next important step is to standardize portion sizes. The portions should be large enough to satisfy customers without excessive waste. They must reflect the potential food cost and menu price.
Some helpful tips for easy portion control:
portion as much as possible ahead of service in the preparation area; use individual dishes if possible; provide appropriate portion control utensils; Frequently spot check plating for proper portions.
Ø Receipt and Storage
One very important component to food cost control that is often overlooked is the receiving of deliveries and goods. Are you receiving all the items you are paying for and do they adhere to your purchase specifications? Do you have a set of scales to check deliver weights? Are they accurate? Are the prices charged the same as those quoted? Is receiving done in a controlled area? Who is doing spot checks of products received? Have they been trained how to do this?
Control of your storage area is critical to maintaining proper cost controls. All storage areas including walk-in stores/sheds should be locked at all times. Keep tabs on all keys. Make sure that the walk-in fridge temperatures are correct and that the thermometers are checked regularly. Track high cost items against sales constantly against sales. Ensure that all production items are code dated and rotated properly.
NOTE
By using some of these tools, actual food cost should be in line with the potential food cost. If, however, a reduction in food cost is necessary and raising prices is not an option, you may want to consider some other course of action.
Review purchase specifications to identify and source alternative products that will not affect the quality of the finished menu item. Consider long-term purchase contracts on high cost or high volume items – or join a purchasing group. Look at portion sizes to see if there is any opportunity to reduce them without affecting customer satisfaction. Another way of reducing costs is to focus on selling more of your higher GP / lower cost items to offset some of the higher cost / low GP items. Appetizers, soups and desserts tend to be lower in food cost and selling at least one of them, along with a main course dish, to each customer can go a long way towards improving profitability and reducing costs. What are you and your staff doing to promote these items? Look for any loss leaders on your menu and ask yourself if they are really working for you.

INTERNATIONAL DISHES
INDIAN CUISINE
Indian cuisine encompasses a wide variety of regional cuisines native to India. Given the range of diversity in soil type, climate and occupations, these cuisines vary significantly from each other and use locally available spices, herbs, meat, vegetables, and fruits. Indian food is also heavily influenced by religious and cultural choices.
The development of these cuisines has been shaped by Hindu and Jain beliefs, and in particular by vegetarianism, which is a growing dietary trend in Indian society. There has also been Persian influence on North Indian cuisine from the years of Mughal and Delhi Sultanate rule. Indian cuisine has been and is still evolving, as a result of the nation’s cultural interactions with other societies.
Historical incidents such as foreign invasions, trade relations and colonialism have also played a role in introducing certain foods to the country. For instance, potato, a staple of North Indian diet was brought to India by the Portuguese, who also introduced chillies and breadfruit. Indian cuisine has also shaped the history of international relations; the spice trade between India and Europe is often cited by historians as the primary catalyst for Europe’s Age of Discovery. Spices were bought from India and traded around Europe and Asia. It has also influenced other cuisines across the world, especially those from Southeast Asia, the British Isles and the Caribbean.
The history of the Buruuj Training Institute (BTI) dates back to July 2006, when its predecessor, the TJ Computer College, commenced training in Sotik Town, Bomet County. In 2008, TJ computer college relocated to Nairobi.
