Vacuum sealing is a food preservation technique that involves removing air from a package before sealing it. This process is typically accomplished using a vacuum sealer machine. The machine suctions the air from the packaging, creating an airtight seal around the contents.
Key Steps in Vacuum Sealing:
1. Preparation: Food items are placed in specially designed vacuum-seal bags or containers.
2. Sealing: The vacuum sealer machine removes the air from the packaging, creating a vacuum and tightly sealing the bag or container.
3. Airtight Barrier: Once sealed, the package forms an airtight barrier around the contents, preventing the entry of air, moisture, and external contaminants.
The benefits of vacuum sealing include:
Extended food freshness and shelf life.
Prevention of freezer burn.
Protection against moisture and air exposure.
Space-saving storage.
Preservation of flavor and nutrients.
