Vacuum packaging extends shelf life because it removes oxygen from around the food. There is no one formula to determine how long that will extend shelf life of all foods. Companies that use vacuum packaging perform shelf life studies on their products and it will vary from product to product or even manufacturer to manufacturer. It also depends upon the quality of the product when it is packaged. Home vacuum packaged food may not last as long as commercially packaged product.

Also remember that vacuum packaging does not take the place of proper storage.
