Answer 2

Answer:

Five common methods of food preservation are 1) refrigeration, 2) canning, 3) pasteurization, 4) drying, and 5) the addition of preservatives.

Explanation:

1) Refrigeration:

• The primary function of a refrigerator is to keep food cool. Food stays fresher for longer when it is kept cold.
• Refrigeration's primary concept is to slow down the action of germs (which all food includes) so that the microorganisms take longer to destroy the food.

2) Canning:

• Canning is a method of preserving a variety of foods by placing them in jars or cans and heating them to a specific temperature.
• To protect the food's safety and quality, high heat kills bacteria and inactivates enzymes.

3) Pasteurization:

• Pasteurization is a food processing procedure that uses a mild heat treatment to destroy hazardous germs (pathogens) and extend the shelf life of a product.

4) Drying:

• Food drying, often known as "dehydrating," is a process of preserving food by removing enough moisture from it to prevent bacteria, yeast, and moulds from growing.

5) Adding preservatives:

• Food is preserved with preservatives to prevent spoiling caused by bacteria, moulds, fungus, and yeast.
• Preservatives extend the shelf life of food by keeping it fresh for longer periods of time.
• Food preservatives are also employed to slow or prevent colour, flavour, or texture changes, as well as to postpone rancidity.
