Verified Answer

Ans. Fried food items containing oil and fat get oxidised and become rancid in the presence of air or oxygen. As nitrogen is a comparatively unreactive gas when compared to oxygen, it prevents the oxidation of food item and hence prevents food from becoming rancid. That is why, oil and fat containing food items are flushed with nitrogen gas.
