Why are potato chips often packed in nitrogen-filled packets?
ANitrogen makes the chips heavier and easier to transport
BNitrogen reacts with oils to improve flavour
CNitrogen helps prevent oxidation of fats and delays rancidity
DNitrogen removes all moisture by dissolving it
Answer & Solution
Correct answer: C. Nitrogen helps prevent oxidation of fats and delays rancidity
Rancidity is caused by oxidation of fats and oils. Filling packets with nitrogen reduces contact with oxygen, so oxidation slows down and the food stays fresh longer.
