What is MAP (Modified Atmosphere Packaging)?
MAP (Modified Atmosphere Packaging) is a process used to extend the shelf life of a food product without the need to freeze. The product is first placed in a suitable tray and a vacuum is applied to remove the majority of the air. The vacuumed air is then replaced with a gas mixture that will prolong the shelf life of the product and also retain the appearance of the food. The tray is then heat-sealed with a suitable film to encapsulate the product and the gas mixture for a recommended duration.
