Answer 1

Flushing nitrogen gas in food products prevents rancidity as it cuts off the supply of oxygen and moisture, which can lead to foul smell and bad taste of the food product. Nitrogen does not react with the food product to make it unhealthy whereas oxygen and mositure together do.

Answer 2

Answer:

When the chips are surrounded by unreactive gas nitrogen, there is no oxygen of air to cause its oxidation and make it rancid, as nitrogen is an inert gas and does not react easily. So, bags used in packing food items are flushed with nitrogen gas to prevent them from becoming rancid.
