Why are chips packets filled with air? Is there any reason or just to earn profit? When looked for answering I got a lot of information.
Chips package are flushed with nitrogen gas to prevent the food from stale. Nitrogen gas prevent the growth of bacteria and fungi. Nitrogen usually will not react with food. Instead of flush with nitrogen gas if we fill these oxygen gas food will easily become rancid. Because oxygen is always ready to react with other molecules. The brings chemical changes and bacteria become to grow in presence of oxygen.
Then the food smells bad and causes digestion problem Also, Nitrogen gas flushed in package prevent the chips from cracking while transport. .So finally getting unbroken, crispy, spicy snack packs.
