Answer 2

Answer:

Nitrogen is an inert gas and thus does not react with fats and oils present in food substances. But the case with oxygen is different as it makes food rancid by reacting it with food items. Thus packing oil and fatty foods with nitrogen and fatty foods will help to sustain the quality of the food for longer by removing the oxygen before packing.
