Why do we preserve food?
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. It’s economic.
What are the basic principles of food preservation?
The basic principle of food preservation includes:
- Preservation or delay of microbial decomposition: That is archived by:
- Keeping out microorganisms (asepsis)
- Removal of microorganisms,i.e., by filtration.
- Hindering the growth of activity of microorganisms,i.e., by low temperature, drying, anaerobic conditions, &
Why do we preserve food Class 5?
