Question

i) Why do we fill chips packets with nitrogen gas? How does it help? (ii) Name the phenomenon due to which the taste and smell of only food changes when kept for a long time in open. Suggest methods to prevent it.

Answer 1

Answer:

i) We fill chips packets with $N_{2}$ gas to prevent the oil present in the chips to react with atmosphere $O_{2}$.

ii) The phenomenon is called Rancidity. We can prevent this by either doing the above, storing it in air-tight containers, or by refrigerating them.
