Vacuum Sealer

真空封口機 - 延長食物的保質期

A vacuum sealer is a machine that removes the air from either a plastic bag or another storage container, and then seals the container to prevent any air from coming in. Vacuum sealing keeps food fresh by removing the oxygen, which bacteria and mold need to grow. It also prevents freezer burn, allowing for frozen items to last longer than if frozen without being vacuum sealed.

Another great use for vacuum sealing is sous vide. Sous vide is a cooking process in which food is vacuum sealed in a bag and then cooked in a water bath to a precise temperature. Sealed completely, the bags do not allow for anything to go in or out of the bags making it the perfect vehicle for this cooking method.
