Which Gas is included in Fry Chips Packets for safety?

Everyday Science Mcqs /
Which Gas is included in Fry Chips Packets for safety?A. Nitrogen gas
B. Carbon dioxide
C. Oxygen
D. Hydrogen

Potato chips packets are filled with air but with NITROGEN GAS.This is done to prevent Oxidising which ultimately results in stale .Oxygen is a very reactive gas and it’s molecules react with air, moisture and result in staling of food .Since nitrogen is less reactive than oxygen hence the packets are filled with NITROGEN gas .
