The Food Saver, and other appliances like it, allow you to vacuum seal food in a plastic bag. While the bags are somewhat expensive, any Food Saver owner will tell you that the cost is more than made up by the food it saves. Leftovers like lasagna and casserole will no longer become freezer burned, even if left in the freezer indefinitely. If you have dry goods that you are not intending to use anytime soon, such as baking cocoa, spices, or raisins, then you can seal them in a Food Saver bag and keep them in a cupboard.

For shoppers who like to buy in bulk, a Food Saver is a must. It allows you to buy foods that come in a large package and then repackage them yourself so that they will keep well. This idea works with anything from meat and poultry to dry goods like rice and flour. Bulk purchases are only a good value if you can use and enjoy your entire purchase. The Food Saver makes that possible.

Because Food Saver bags are both airtight and watertight, they provide an excellent way to pack snacks like granola, candy, or jerky to take on outdoor excursions. Even if your backpack gets drenched, your food will be perfectly dry and fresh.

The Food Saver can cost over $200, and replacement bags can cost roughly $0.50/foot. However, there are several other vacuum sealers on the market.
