How Vacuum Sealing Extends Shelf Life
Principle

Limitations
Vacuum sealing does not kill bacteria already present. It is not a substitute for proper refrigeration or safe handling. Anaerobic bacteria (like botulism) can still grow in low-oxygen environments at unsafe temperatures.
Example Calculation
Vacuum-sealed cheese stored in the freezer (normally 5 days in fridge).
- 01Normal fridge life = 5 days
- 02Freezer extension factor = 3x
- 03Vacuum sealed freezer life = 5 x 3 = 15 days
- 04This is a rough estimate; hard cheese lasts much longer.
