The modified atmosphere concept for packaged goods consists of modifying the atmosphere
surrounding a food product by vacuum, gas flushing or controlled permeability of the packthus controlling the biochemical, enzymatic and microbial actions so as to avoid or decrease
the main degradations that might occur. This allows the preservation of the fresh state of the
food product without the temperature or chemical treatments used by competitive preservation
techniques, such as canning, freezing, dehydration and other processes.

The normal composition of air is 21% oxygen, 78% nitrogen and less than 0.1% carbon
dioxide. Modification of the atmosphere within the package by reducing the oxygen content
while increasing the levels of carbon dioxide and/or nitrogen has been shown to significantly
extend the shelf-life of perishable foods at chill temperatures!!
