Question

What is food preservation? Describe in detail any four common methods of food preservation.

Accepted Answer

Food preservation is the process of treating the food in a manner to slow down its spoilage, without affecting its nutritional value. Four common methods of preserving food are mentioned below.

1. Boiling: Milk and water are usually boiled to kill any harmful bacteria which could be present in them.

2. Dehydration: Microbes need adequate moisture to grow. Food items such as cereals and pulses are generally dried under the sun to remove the moisture present in them and prevent microbial growth.

3. Canning: The canning process is an air-free packing used to preserve food materials to prevent spoilage. In this process, the food material which is to be canned is heated at a high temperature to kill bacteria and spores. Food items such as vegetables, fish, cooked food, etc., are preserved using this method.

4. Using salt and vinegar: Salt and vinegar create an environment that prevents microbial growth. Food items such as meat, pickles, jams, etc., are stored by this method.
