Vacuum packing

From Wikipedia, the free encyclopedia

Vacuum packing is a method of storing food and presenting it for sale. Appropriate types of food are stored in a vacuum environment, usually in an air-tight bag or bottle. The vacuum environment removes atmospheric oxygen and any free moisture making it very difficult for bacteria or fungi to grow thus preventing the food from spoiling. Vacuum packing is commonly used for storing dry foods such as cereals, nuts, cured meats, cheese and smoked fish.

Vacuum-packing products using bags, canisters, bottles, or mason jars are available for home use.
