Does Vacuum Sealing Remove All Air?
Vacuum sealing removes a significant portion of air present in a bag or container, but it does not remove all air. It depends on the vacuum sealer and the quality of the bag used for sealing. Some air may still remain in the bag, but it is reduced enough to extend the shelf life of food and prevent freezer burn. It is important to note that some items, such as fruits and veggies, release gases and can cause the bag to expand after vacuum sealing, which may result in air pockets.
