Which gas is filled in packets of chips to reduce rancidity?
Answer and explanation
Correct answer: Nitrogen
The oils and fats in chips can react with oxygen in air and become oxidised, causing rancidity. Filling the packet with nitrogen reduces the amount of oxygen present. Nitrogen is relatively unreactive, so it slows the oxidation of oils. Carbon dioxide may be used in the packaging of some foods, but nitrogen is commonly used in packets of chips.
