What is Modified Atmosphere Packaging (MAP)?Modified atmosphere packing (MAP) packs are produced by evacuation and gas flushing. This combination gas usually consists of carbon dioxide, nitrogen and oxygen.

A gas flushing for modified atmosphere is incorporated prior to heat-sealing of the container.

What gases are application in Modified Atmosphere Packaging (MAP)?Combination gases as follows is very often used

Oxygen (O2): in high concentration inhibits the growth of aerobic microorganisms.

Nitrogen (N2): mainly used as a stabilizing gas to maintain the pack volume for protection during handling or as transportation packaging.

Carbon dioxide (CO2): reacts with water to form carbonic acid, which helps to lower the PH. This atmosphere inhibits the growth of micro-organisms.

Why has Modified Atmosphere Packing (MAP) become popular?In the case of fresh meat and poultry, fresh pasta and baked products, and fresh-prepared foods, the modified atmosphere compliments refrigeration to retard chemical and/or microbiological deterioration of the food.

Packaging many fresh fruits and vegetables in a modified atmosphere with selected low oxygen content and elevated carbon dioxide content reduces respiration, with resulting increase in shelf life.
