Cooking

The diversity of cooking worldwide is a reflection of the myriad nutritional, aesthetic, agricultural, economic, cultural and religious considerations that impact upon it.

Cooking frequently, though not always, involves applying heat in order to chemically transform a food, thus changing its flavor, texture, appearance, and nutritional properties. There is archaeological evidence of cooked foodstuffs (both animal and vegetable) in human settlements dating from the earliest known use of fire

Effects of cooking

Food safety

If heat is used in the preparation of food, this can kill or inactivate potentially harmful organisms including bacteria and viruses. The effect will depend on temperature, cooking time, and technique used. The temperature range from 4°C to 60°C (41°F to 140°F) is the "food danger zone." Between these temperatures bacteria can grow rapidly. Under the correct conditions bacteria can double in number every twenty minutes. The food may not appear any different or spoiled but can be harmful to anyone who eats it. Meat, poultry, dairy products, and other prepared food must be kept outside of the "food danger zone" to remain safe to eat. Refrigeration and freezing do not kill bacteria, but only slow their growth.
