Ever body knows that in order to maintain the long shelf life of a packaged food, we displace oxygen by infusing nitrogen in the package. Nitrogen maximizes the food durability and prevent it from getting spoilt.
Purpose of using Nitrogen in Food packaging Nitrogen is used in packaged food to displace oxygen. Bacteria uses oxygen to grow and thrive on organic material because oxygen carries moisture which is a favourable condition for bacteria to grow. By removing oxygen, it gets difficult for bacteria to grow and the food will not get oxidized. Oxidization can cause the food to become inedible and foul-smelling. The best example of oxidization is a cut or bitten apple that gets dark and brown after a few minutes it is cut/bitten. This process is of displacing oxygen and flushing nitrogen in packaged food is known as Modified Atmosphere Packaging (MAP). MAP is a method of increasing the shelf life of food products by packaging them in nitrogen atmosphere that prevents it from getting spoilt.
