Which Gas is included in Fry Chips Packets for safety?
Correct answer: A. Nitrogen gas
- A. Nitrogen gas
- B. Carbon dioxide
- C. Oxygen
- D. Hydrogen
Explanation
Nitrogen is used because it is largely inert and displaces oxygen inside the packet, slowing oxidation and spoilage of the chips. Carbon dioxide can also be used in some food packaging, but nitrogen is the standard gas for fried-chip packets.
