By removing oxygen when storing foodstuffs, you can extend the shelf-life of the food you are storing. For example, meat will normally last about six months in the freezer, but if you vacuum seal the meat first and then freeze it, it can last up to two years. Vacuum sealing is also good for storing food such as nuts, which contain fats and which normally go rancid in oxygen.
Here are the best vacuum food storage solutions on the market:
