QUESTION
The average specific gravity of skimmed milk is?
OPTIONS
(A) 1.035 to 1.037
(B) 1.028 to 1.030
(C) 1.030 to 1.032
(D) 1.032 to 1.034
ANSWER
(A) 1.035 to 1.037
EXPLANATION
Removing fat increases the specific gravity of milk because milk fat is less dense than the serum phase. Skim milk therefore commonly has a specific gravity around 1.035–1.037, higher than ordinary whole milk. Hence, option (A) is correct.
