Question

Oil and fat containing food items are flushed with nitrogen. why?​

Answer 1

Answer:

Nitrogen is unreactive gas as compared to oxygen. Oil and fat present in the food items get oxidised and become rancid in the presence of air or oxygen. But such reaction is prevented in the presence of nitrogen. Therefore, food items like potato chips etc., are packed with nitrogen gas to prevent them from rancidity for a long time.

Answer 2

Answer:

Nitrogen is an inert gas, hence it acts as antioxidant and prevents the oils and fats from oxidation. Thus, oils and fats are flushed with nitrogen to prevent their oxidation and stop odor.
