Filling potato chips packets with nitrogen gas reduces which problem?

Answer and explanation

Correct answer: Rancidity

The oils and fats in chips can oxidise in the presence of oxygen in air, producing an unpleasant smell and taste. This process is called rancidity. Filling the packet with nitrogen reduces the oxygen available, so oxidation of the oils and fats slows down. Rusting involves oxidation of iron, whereas oils in chips undergo rancidity.
