What is vacuum sealing and how does it work?
Vacuum sealing is a method of packaging that removes air from the container before sealing it. This process helps to extend the shelf life of food by slowing down spoilage, preventing freezer burn, and inhibiting the growth of bacteria and mold. By creating a vacuum, the oxygen that contributes to these processes is minimized, thus preserving the freshness and quality of the packed items.
The vacuum sealing process typically involves placing food or items in a specially designed plastic bag or container. A vacuum sealer machine then removes the air from the bag and seals it tightly, often using heat. This results in a compact package that is not only easier to store but also reduces the risk of freezer burn compared to traditional storage methods.
