Among the oldest methods of preservation are drying, refrigeration, and fermentation. Modern methods include canning, pasteurization, freezing, irradiation, and the addition of chemicals. Advances in packaging materials have played an important role in modern food preservation.

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.

a)Food preservation is the process of treating and handling food to stop or slow down Food spoilage , loss of quality, edibility or nutritional value and thus allow for longer food storage.

Objectives of Food Preservation

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

What are the five causes of food spoilage? ›

Various factors cause food spoilage, making items unsuitable for consumption. Light, oxygen, heat, humidity, temperature and spoilage bacteria can all affect both safety and quality of perishable foods.

Food processing is the transformation of raw ingredients into food products that can be eaten by physical or chemical means. Food preservation slows or stops food spoilage by various methods, including drying, freezing, pickling, and irradiation.
