It may then bring several question to the mind like why we do cook, how cooking affect the food ,does cooking has negative or positive effect on the food and the types of cooking method available. If you have ever pondered about cooking on itself, this is why this write up is written which is to educate potential readers about cooking generally..
The process of subjecting foods to the action of heat is termed as cooking.Foods like fruits, vegetables and nuts are eaten raw but most of the foods are cooked to bring about desirable changes.Cooking is one of the most popular food preparation activity in the world.
Cooking as food processing activity is done because of the following reasons:
Cooking as a process involves the use of heat, a food is a chemical and biological material which tends to be affected by heat. Most of the time if the food is subjected to what is called overheating the following are bound to happen.
Yes of course, there are several cooking method. Cooking requires heat and Heat may be transferred to the food during cooking by conduction, convection, radiation or by the energy of microwaves—electronic heat transfer.The following are the types of cooking method.
It is cooking foods by just immersing them in water at 100°C and maintaining the water at that temperature till the food is tender.It is the most simple method. It does not require special skill and equipment but if not done at the right temperature and time of cooking there may be loss of nutrient.
When foods are cooked in a pan with a well-fitting lid at temperature just below the boiling point 82-99°C of the liquid in which they are immersed the process is known as simmering.
This involves cooking in the minimum amount of liquid at a temperature of 80-85°C that is below the boiling point.
This is a gentle method of cooking in a pan with a tight-fitting lid, using small quantities of liquid to cover only half the food.
This method requires the food to be cooked in steam. This is generated from vigorously boiling water or liquid in a pan so that the food is completely surrounded by steam and not in contact with the water or liquid.
A relatively small increase in temperature can drastically reduce cooking time and this fact is utilized in pressure cookers.
It consists of placing the food below or above or in between a red hot surface. When under the heater, the food is heated by radiation only.
When food is cooked uncovered on heated metal or a frying pan the method is known as pan broiling.
Here food gets cooked by hot air. Basically it is a dry heat method of cooking but the action of dry heat is combined with that of steam which is generated while the food is being cooked.
This is the cooking with the aid of solar energy. The source of heat is obtained from the sun.
