Answer 2

Answer:

TL;DR _ To prevent spoiling of food from oxidation

Explanation:

• Rancidity is the process of a change in the flavour and taste in food containing oil and fats.

• Oil and fat foods consists of fatty acid molecules having hydrogen ions. when oxygen is in contact with these food, then the substitution destabilises the molecule as the oxygen replaced the hydrogen ions through oxidation. thus the food emits out other odd chemical fragments and we perceive the odd and unpleasant smell of the rancid food.

• Therefore, to overcome this problem, the chips manufacturers often flush in nitrogen ( an inert gas ) which prevents the oxidation to an extent. the chips containing oil and fat is thus retained without spoil.
