Aims & Objective of Cooking


What is Cooking?
Cooking is a chemical process where in raw materials are exposed to heat to get a finished
product of a certain desired quality with a change in physical state also.

Aims of cooking

Objectives of Cooking:
  • Improves the taste and food quality
Cooking improves natural flavour and texture of food. For example roasting groundnuts,
frying onions and papads, cooking rice and roasting coffee seeds improve the flavour.
Cooking meat with spices, rice with spices in making pulav, frying cashew nuts in ghee,
addition of turmeric, curry leaves, pepper in pongal, blend flavour with one another during
cooking.
Too much of cooking lowers the flavour as flavouring compounds are
volatile. Over cooked pulav, does not taste as good as well cooked pulav.
  • Destruction of microorganisms
Microorganisms are present everywhere and some are useful in making curd, cheese and
bread. Some are harmful and cause infections or produce toxins, e.g. clostridium botulism
and salmonella. Some moulds produce toxins. Aspergillus flavus produces aflatoxin in
groundnuts, cereals and spices. This aflatoxin is a health hazard.
One of the most important method of protection of food against harmful
micro organism is by the application of heat. Cooking food to the required
temperature for a required length of time can destroy all harmful
microorganisms in food e.g. pasteurised milk.
Tapeworm or its larvase which infests pork can be killed by proper
application of heat. By cooking, food is made safe for consumption.
  • Improves digestibility
Cooking softens the connective tissue of the meat and the coarse fibres or cereals, pulses
and vegetables so that the digestive period is shortened and gastro intestinal tract is less
subjected to irritation. Cooking improves the texture hence it becomes more chewable.
Cooking also bursts the starch granules of pulses and cereals so that the starch digestion is
more easier, rapid and complete. When dry heat is applied to starches they are converted to
easily digestible dextrins. Cooking increases the access to enzymes and improves
digestibility.
  • Increases variety
By cooking, same food can be made into different dishes. For example rice can be made
into plain, pulav, lemon rice, biriyani, or combination with pulses into idli. Wheat can be
made into chapatis, puri, paratha or halwa.
  • Increases consumption of food
Cooking improves the texture and makes the food chewable. Improvement in texture and
flavour by cooking increases the consumption of food to meet our nutritional requirement.
  •  Increases availability of food
Raw egg contains avid in which binds biotin making biotin unavailable to the body. By
cooking, avid in gets denatured and biotin is available to the body.
Trypsin inhibitors present in soyabean and duck egg get denatured on
cooking and availability of protein is improved. Toxic substances from
kesari dhal can also be removed by boiling it and throwing away the water.

Objective of cooking
  1. Retaining the nutritive value of the food.
  2. Retaining the original colour of the food.
  3. Prevent the clash of colour.
  4. Avoid undercooking
  5. Avoid overcooking

    Thanks for your sharing such valuable cooking ideas with us. I'm a big fan of cooking and I love to do it all day. I listen to several famous chefs, try their recipes, and even read blogs and cookbooks too. Anything that'll help me to improve my cooking. Can you please guide me on which cookbook should I read for more ideas? I'm currently reading The Dressing Table and I found it very helpful and enjoyed the recipes a lot. Please share your thoughts as well. Keep posting stuff like this.

ATTITUDE AND BEHAVIOUR IN THE KITCHEN

ATTITUDE AND BEHAVIOUR IN THE KITCHEN What does it take to be a good food service worker? The emphasis of a food service education is on learning a set of skills. But in many ways, attitudes are more important than skills because a good attitude will help you not only learn skills but also persevere and overcome the many difficulties you will face. The successful food service worker follows an unwritten code of behaviour and set of attitudes we call professionalism . Let’s look at some of the qualities a professional must have. POSITIVE ATTITUDE TOWARD THE JOB In order to be a good professional cook, you have to like cooking and want to do it well. Being serious about your work doesn’t mean you can’t enjoy it. But the enjoyment comes from the satisfaction of doing your job well and making everything run smoothly. Every experienced chef knows the stimulation of the rush. When it’s the busiest time of the evening, the orders are coming in so fast you can hardly keep track o...

Introduction to the art of cookery & Culinary history

Introduction  Cookery is defined as a ―chemical process the mixing of ingredients; the application and withdrawal of heat to raw ingredients to make it more easily digestible, palatable and safe for human consumption. Cookery is considered to be both an art and science. The art of cooking is ancient. The first cook was a primitive man, who had put a chunk of meat close to the fire, which he had lit to warm himself. He discovered that the meat heated in this way was not only tasty but it was also much easier to masticate. From this moment, in unrecorded past, cooking has evolved to reach the present level of sophistication. Humankind in the beginning ate to survive. Now also we still eat to survive, however efforts have been made to make the food more enjoyable like cooking meats and vegetables in different ways to make them more easily eaten, digestible and to make them more attractive, palatable and to have wider choice. This is the art associated with the preparation of food. H...
