Question:
The presence of which of the following enzyme in milk is used as an index of the efficiency of pasteurization?
The presence of which of the following enzyme in milk is used as an index of the efficiency of pasteurization?
Show Hint
Phosphatase: pasteurization indicator.
Inactivated by pasteurization.
Phosphatase test confirms proper pasteurization.
Inactivated by pasteurization.
Phosphatase test confirms proper pasteurization.
Updated On: Aug 18, 2026
- Catalase
- Phosphatase
- Peroxidase
- Lactoperoxidase
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Pasteurization efficiency is tested using enzyme activity.
Certain enzymes are used as indicators.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the enzymes used for pasteurization testing.
Step 3: Detailed Explanation:
Phosphatase is used as an index of pasteurization efficiency.
It is inactivated at pasteurization temperature.
Catalase is not an indicator.
Peroxidase is more heat-stable.
Lactoperoxidase is also heat-stable.
Thus, phosphatase is the correct enzyme.
Step 4: Final Answer:
Phosphatase is used as an index of pasteurization efficiency.
Hence, the correct option is (B). \bigskip
