Answer 2

Answer:

Food preservation is one of the methods to protect food from unwanted microbial growth. After the food is produced, we store and protect by covering the rice and curry with lids to keep away flies and other insects. By this, we are protecting it from any infection caused by them. This is a short-term condition. Food preservation, on the other hand, is done to preserve food for a longer time.

Following are the important objectives of food preservation:

• To prevent microbial contamination.
• To kill pathogens.
• To minimise food spoilage and food poisoning.
