Question

Coconut oil is fatty substance, hence must be composed of fatty acids. Then why doesn't it taste sour?

Answer 1

There are two reasons:

Explanation:

First: The fatty acids are not there in the form of free acid in coconut , but bound into more complex compounds (fats).

()

In 100gm dessicated coconut you will get about 65 to 66 gram of fat, which is made of fatty acids attached to glycerol by ester bonds.

Second: even pure fatty acids won't taste very sour . As the carbon chains get longer, the acid part has less and less influence on the taste. Sensation of fat on tongue is distinct but there is no particular term for it.
