Solution
Rancidity:
Rancidity is the process by which fats and oils undergo total or incomplete oxidation or hydrolysis when exposed to air, light, or moisture, or by bacterial action, resulting in an unpleasant taste and odour.
Packet of chips is not filled with oxygen:
During the chip packaging process, air and, in particular, oxygen is eliminated.
The goal is to prevent the chips from becoming oxidized, which would cause them to become stale or soggy.
Because oxygen is highly reactive, it tends to interact with other molecules, causing chemical changes that may damage the chips.
Packet of chips is filled with nitrogen:
Nitrogen is a relatively stable and non-reactive gas.
A 'nitrogen atmosphere' is thought to be beneficial, particularly for food storage.
Nitrogen is a harmless gas that is used in the packing process. Food and beverage industries continuously utilize nitrogen as it has inert nature and does not allow food to oxidize.
