Question

why is food preserved
​

Answer 1

Answer:

Bacteria only need warmth, moisture, and time to rapidly multiply in food, but food preservation inhibits one or more of these conditions and stops their growth.

Answer 2

Answer:

The primary objective of food preservation is to prevent food spoilage until it can be consumed. Gardens often produce too much food at one time more than can be eaten before spoilage sets in.  Preserving food also offers the opportunity to have a wide variety of foods year-round.
