Modified Atmosphere Packaging
MAP - An atmosphere with a gas composition different from that of air is created in the package. The gases mainly used are the following:
CO2 – Antimicrobial effect;
O2 – A reduced oxygen concentration in the head-space of a package below 1-2 %, even to 0.2 % by replacing oxygen with nitrogen and /or carbon dioxide;
- A high oxygen concentration, even 80 % or above is used in order to inhibit microbial growth through oxygen shock;
N2 – Inert gas (equilibrium of atmospheric pressure).
