QUESTION
Milk fat is easily separated from milk?
OPTIONS
(A) Because it is lighter than other constituents
(B) Because it is not uniformly mixed in milk
(C) Because it has more specific gravity
(D) Because it has less specific tension
ANSWER
(A) Because it is lighter than other constituents
EXPLANATION
Milk fat has a lower density than the aqueous phase of milk, so fat globules tend to rise and can be separated by gravity or, much more efficiently, by centrifugal separation. The fat is dispersed as an emulsion rather than being simply “not uniformly mixed,” and it does not have greater specific gravity. Hence, option (A) is correct.
