Which of the following gases is generally used to flush bags of chips by the manufacturers?
Show answer & explanation
Correct answer: B
Explanation
The correct Answer is option 2 i.e. Nitrogen .
Manufacturers flush bags of chips with nitrogen gas to keep them fresh and crisp. Nitrogen prevents the chips from getting crushed and protects them from oxidation and moisture, which can make them stale or rancid. It’s a harmless, inert gas that replaces oxygen inside the packet, ensuring a longer shelf life.
Other options:
-
Compressed air: Contains oxygen and moisture, which would spoil the chips.
-
Oxygen: Promotes oxidation and makes chips go stale quickly.
-
Carbon dioxide: Can alter taste and make the chips soggy over time.
