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. However, it is also used for storing fresh foods such as Fresh picked vegetables, Fresh meats and liquids such as soup broth and water.

The invention of the first commercially reliable vacuum sealing process is credited to the Hills Bros. coffee company, a San Francisco-founded concern that once commanded the largest share of the American coffee market. Being the first to market with the vacuum seal process was a great boon for the company.

Vacuum packing is also used to keep goods dry and protected from the elements. Some people who engage in "outdoors" activities such as hiking, camping, and climbing will use a motorized vacuum sealer to pack up their t-shirts and other articles of clothing so as to fit much more clothing in their packs.

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