Nitrogen flushing is a method used to preserveandprotect food from damage during shipping andstorage.Nitrogen replaces the oxygen in a food storage bag,and itcushions the contents. Unlike oxygen, nitrogen doesn'treactwith foods or affect the flavor or texture, so they stayfresherlonger..
Simply so, why is nitrogen used in packaging?
The presence of oxygen introduces moisture whichcandeteriorate the food quality. Another reason thatnitrogengas is often used for food packagingis to provide apressurized atmosphere that prevents packagecollapse.
what is gas flush packaging? Gas flush consists of an inert gas suchasnitrogen, carbon dioxide, or exotic gases such as argonorhelium which is injected and frequently removed multiple timestoeliminate oxygen from the package. This technique is calledMAP(Modified Atmosphere Packaging).
Also to know is, why nitrogen is flushed in packaged food stuff?
When the chips are surrounded by unreactivegasnitrogen, there is no oxygen of air to cause itsoxidationand make it rancid, as nitrogen is an inert gas anddoes notreact easily. So, bags used in packing food itemsareflushed with nitrogen gas to prevent themfrombecoming rancid.
Is nitrogen packed food safe?
Nitrogen food packaging is used forpreservationand storage because it is a nonreactive gas that isnon-toxic,non-odorous, and is widely available. In fact,nitrogenmakes up 78 percent of the air we breathe. All thesetraits makenitrogen food storage safeandaffordable.
