What is the main reason for filling potato-chip packets with nitrogen gas?

Answer and explanation

Correct answer: To prevent oxidation of oils and fats and reduce rancidity

Chips contain oils and fats that can react with oxygen in air. This oxidation causes rancidity, producing an unpleasant smell and taste. Nitrogen is relatively unreactive and reduces the amount of oxygen in the packet. Therefore, option A is correct; nitrogen does not make chips sweet or increase their moisture.
