Suggested Gas Mixtures for
Modified Atmosphere Packaging

 

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. The table below lists some of the modified atmospheres that have been applied to common food products.

Topac supples a range of products for the quality control of packages using modified atmosphere.
