What is rancidity ? Why the packets of chips and fries are flushed or filled with nitrogen gas while packing?

It is the foul smell produced by the oxidation of oils and nuts.

Mostly the bitter taste of peanut and food made by frying is due to rancidity .

Normally the oily substances which are not covered properly , react with the oxygen of air and get oxidised thus give a foul smell.

Removal of oxygen avoids the oxidation of fool items. So during packaging nitrogen gas is used to make inert atmosphere .

That is the reason most of the chips are packed with plenty of Nitrogen gas.
