Spoilage of oil can be detected by which fatty acid : -
A
Oleic acid
B
Linolenic acid
C
Linoleic acid
D
Erucic acid
Detailed Solution
Erucic acid is a long chain (C22) monounsaturated fatty acid present in large amounts in mustard and rapeseed oil.
High erucic acid content is considered harmful (it is linked to heart damage in animal studies), so it is used as an indicator of the quality of edible oils; low erucic acid varieties (e.g. canola) have been developed.
So, as per the answer key, spoilage (poor quality) of oil is detected by erucic acid.
