Question

Fatty food become rancid due to the process of
(A) oxidation
(B) corrosion
(C) reduction
(D) hydrogenation

Answer 1

Hint: To solve this question, firstly refer to what is rancidity and as we know it is associated with fatty food materials such as butter, oil and animal fats and so on. So, we can find out the process which is responsible for the fatty foods becoming rancid.

Complete answer:
We have been provided that fatty foods become rancid,
We need to tell the process responsible for this,
So, for that:
Firstly, we know that rancidity is basically the spoilage of especially fatty food in such a way that it becomes unsafe for consumption,
So, we need to find the reason behind it,
So, the first process that we have been given is oxidation,
So, as we know that oxidation is a process in which a compound reacts with oxygen to get oxidized,
And this is what happens when unsaturated fatty acids or lipids present in the fatty food reacts with atmospheric oxygen, and then the food become rancid and undesirable for consumption,
The next option that we have corrosion,
And we know that when iron comes in contact with oxygen and moisture a brown layer is formed on the metal, which is corrosion,
The next option is reduction,
We know that in reduction basically electrons taken up by the substance reduced are supplied by another substance,
The last option that we have is hydrogenation,
We know that during hydrogenation process the compound react with molecular hydrogen,
So, from this we can say that fatty food become rancid due to the process of oxidation,

So, we can say that the correct option is (A).

Note:
Rancidity has certain limitations that the substance which becomes rancid smells bad and also the taste of the food becomes bad, so it is unfit for consumption.
