Question

Which gas is flushed in a bag of chips to prevent the chips from getting oxidized?
1. Oxygen
2. Nitrogen
3. Hydrogen
4. Helium

Answer 1

Correct Answer - Option 2 : Nitrogen

The Correct Answer is Nitrogen.

 

• Nitrogen is used during the packaging process to exclude and remove air and prevent oxidation. 
• Oxygen is highly-reactive and it combines with other molecules, which results in food spoiling or losing its' freshness.

 

Rancidity

• Rancidity, condition produced by aerial oxidation of unsaturated fat present in foods and other products which gives unpleasant odor or flavor.
• When a fatty substance is exposed to air, its unsaturated components are converted into hydroperoxides, which break down into volatile aldehydes, esters, alcohols, ketones, and hydrocarbons.
• This gives out bad smell.
