What does MAP mean in conjunction with vacuuming?
Many soft and formable foodstuffs are either squashed when vacuuming or not enough air can be extracted to pack them safely. This is where the MAP process comes in. MAP means Modified Atmosphere Packaging – after vacuuming, the vacuum bag or MAP tray is injected with a protective gas tailored to the product. This significantly prolongs the shelf life of the food (MAP table).
