Question

( long answer question ) why food needs to be preserved​

Answer 1

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.

Answer 2

Answer:

Food preservation slows down the activity of disease-causing bacteria or kills bacteria in food altogether. Preserving food keeps it from spoiling too quickly and allows it to last for weeks or even months.
