  • Destruction of micro organisms

Micro organisms are ubiquitous and some are useful in making curd, cheese and bread. Some are harmful and cause infections or produce toxins, e.g., Clostridium botulinum and Salmonella sp. Some moulds produce toxins like Aspergillus flavus produces aflatoxins in groundnuts, cereals and spices which is health hazard.

One of the most important methods of protection of food against harmful micro organisms 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., pasteurized milk.

  • Improves digestibility

Cooking softens the connective tissues of meat and the coarse fibers of cereals, pulses and vegetables so that the digestive period is shortened and gastrointestinal tract is less subjected to irritation. It improves the texture hence it becomes easy to chew and swallow. Cooking also bursts the starch granules of cereals and pulses so that the starch digestion is easier, rapid and complete. It 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, biryani or combination with pulses like idli. Wheat can be made into chapattis, puri, paratha or halwa.

Cooking improves the texture and improvement in texture and flavor by cooking increases consumption of food to meet our nutritional requirement.

  • Increases availability of nutrients

Raw egg contains avidin which binds biotin making biotin unavailable to the body. By cooking, avidin 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. Cooking increases the quality of protein by making some amino acids available to the body.

Studies have shown that when iron pans are used for cooking, the iron content of the food increases. This iron is then made available to the body.
