When we eat chips we find them filled till half of the packet.


During my childhood, I had misconception that manufacturers do this intentionally to make profit but then I understood the purpose.

As chips contain fats and oils in them, they can get rancid.

Rancidity is biochemical reaction of fats getting oxidised to produce foul smell and taste which makes the product unfit for consumption.

So to avoid this, manufacturers fill the packets of chips with nitrogen gas molecules.



Since, Nitrogen gas does not react with fats and oils, the chips are safe from getting rancid.

Moreover, a gas in the bag serves as a cushioning agent and prevents chips from crumbling.

So although we feel it's unfair that packet is filled upto half, it's for a good reason.

So I conclude some things may seem wrong but are for right purpose.
