Answer 1

Hint: Think about the chips packets or the other favorite food item. Gas which is inside them makes the packet look so big. Here is our answer: Nitrogen flushing could be a method accustomed to preserve and protect food from damage during shipping and storage. Nitrogen replaces the oxygen in an exceedingly food storage bag, and it cushions the contents. Unlike oxygen, nitrogen doesn't react with foods or affect the flavour or texture, so that they stay fresher longer.

Complete answer:

Oil and fat containing food items are flushed with nitrogen because nitrogen acts as an antioxidant and it prevents them from being oxidised.

 Nitrogen being an argonon and doesn't easily react with these substances. On the other hand, if the potato chips packets are flushed with oxygen, oxygen would react with food substances and make them rancid. Thus, bags utilized in packing food items are flushed with nitrogen gas to get rid of oxygen inside the pack. When oxygen isn't present inside the pack, rancidity of oil and fat containing food items is avoided.

 Hence the assertion is correct and the rationale is additionally correct.

Therefore, option (A) is correct.

Note: Rancidity could be a condition during which the substance with oil and fats get oxidized once they are exposed to air. A substance is alleged to be rancid when there's a change in smell, taste, and colour. An example of rancidity is when a chips pack is exposed to atmospheric air which ends during a change in taste and odor.
