Why do potato chip manufacturers fill the packet of chips with nitrogen?
July 12, 2015 7:07PM
Chip packages are filled with nitrogen gas to stop oxidation, and thus spoilage, of the chips. In the abscence of oxygen they cannot oxidize.
nitrogen being an unreactive gas,retards bacterial growth and keeps the ffod from decaying.
When fats and oils are oxidised, they become rancid and their smell and taste change. Food items containg oil and fat are flushed with nitrogen to prevent rancidity of oil and fat as nitrogen is an inert gas and prevent the oxidation of oil and fats.
Nitrogen is added to the potato chip packet to add strength to
the packaging. Normally aluminum cans are used for packaging
beverages, these beverages are carbonated drinks and the carbon
dioxide present in them provides the internal pressure in the can
and thus gives internal strength to the aluminum can. But in
non-carbonated drinks, there is no carbon dioxide present and so
Nitrogen is added to it to give the required strength to the
To retard (slow) changes of oxidation.
