Instrumentation for MAP
Modified atmosphere packaging is a technique used to to extend the shelf life and freshness of a wide range of food products. The technique involves modifing the normal atmosphere of the air inside the food package by changing the proportions of Oxygen, Nitrogen and Carbon Dioxide. Different foods and degradation agents react differently to the presence and concentration of these three gases.

Modified Atmosphere Packaging (MAP) involves the modification of the head space gas in a package in order to prolong the shelf life of the product it contains. (food, pharmaceuticals etc.) The success of MAP depends on the packer's ability to correctly prepare the product and to control the concentrations of head space gas within the desired limits.
Topac offers a range of instruments related to the study and implementation of MA (modified atmosphere) and CA (controlled atmosphere) packaging.
