QUESTION
Efficiency of pasteurization is measured by?
OPTIONS
(A) pH test
(B) Lipase test
(C) Amylase test
(D) Phosphatase test
ANSWER
(D) Phosphatase test
EXPLANATION
Adequacy of milk pasteurization is routinely assessed by the alkaline phosphatase test because this native milk enzyme is inactivated by proper pasteurization conditions. pH, lipase, and amylase tests are not the standard indicators of successful pasteurization. Hence, option (D) is correct.
