potato chips manufactures fill the packets of chips with a gas. Name the gas that is filled &state the reasons for its filling
Answers
Answer:
Nitrogen gas
Explanation:
because it prevents to oxidation with air and prevents stale noss of chips
so they use air along with nitrogen gas
Answer:
HERE IS YOUR ANSWER!!!!
Explanation:
Potato chips bags are not full of air but of nitrogen gas. This is done to prevent the chips from oxidizing, which is part that makes them go stale.
Oxygen is very reactive and likes to combine with other molecules whenever it can, causing chemical changes to take place.Another reason is to prevent rancidity. Nitrogen prevents the oxidation of the fats and oils.
A packet of chips is vulnerable to getting squished. Squished chips are subpar. You could put the chips in a solid container that resists squishing, but that makes the package bulky and expensive.
Gases provide good protection from breakage and the air is a very common gas.
Remember that a lot of packaging is either bubbles of air (bubble wrap) or or foamy soft shapes.( air trapped in a solid).
The problem with air is that it contains oxygen. Oxygen however, is chemically corrosive, and will cause the chips to spoil quickly.
Nitrogen is a gas in the air so is readily available. Nitrogen does not affect the food, and when released into the air has no affect. (It forms only a tiny % increase of nitrogen to your local air.
Unlike oxygen ( an oxidising gas),nitrogen is inert. Nitrogen inhibits the growth of aerobic bacteria,which in turn,helps elongating the shelf life of the chips.
Also,the cushion of nitrogen prevents the chips from being crushed while they are transported in bulk from the factory to the stores.
