What is the head gas analysis?
If you are ordering foods packed in a nitrogen flushed oxygen free container (with or without an oxygen absorber packet added) then ask about the laboratory test results that measure the oxygen content of the head gasses in the container. This is of great importance if you are counting on the extra storage life such packaging will give you. There are but a few companies such as Perma Pak, Ready Reserve, and Walton Feed that actually produce packaged storage foods and most dealers only distribute and retail their products. If the dealer can not produce the manufacturer’s test data measuring the head gasses of the products they are selling then keep looking.
