Nitrogen is an inert gas and does not easily react with these substances. On the other hand, oxygen reacts with food substances and makes them rancid. Thus, bags used in packing food items are flushed with nitrogen gas to remove oxygen inside the pack. When oxygen is not present inside the pack, rancidity of oil and fat containing food items is avoided.

To prevent the oxidation of oil and fat present in food items, nitrogen gas is flushed in food packets products formed due to oxidation of oil and fat have unpleasant smell and taste due to rancidity. Flushing food items containing fat and oil with nitrogen prevents rancidity.

Nitrogen is an inert gas which does not react easily with other elements. But oxygen reacts with food materials. To remove oxygen present in packing it is burned with Nitrogen. If there is no oxygen in the pack it prevents oxidation. Hence oil and fat containing food items are flushed with nitrogen.
