Question:

Match List-I with List-II.

List-I

A. Phosphatase Test

B. Turbidity Test

C. Alcohol-Alizarin Test

D. Platform Test

List-II

I. Check the quality of incoming milk

II. Check efficiency of pasteurization

III. UHT milk

IV. Determine heat-stability of milk

Choose the correct answer.

• A. A-II, B-III, C-IV, D-I
• B. A-I, B-II, C-III, D-IV
• C. A-II, B-IV, C-III, D-I
• D. A-III, B-II, C-I, D-IV

Hint:

Phosphatase test = pasteurization check.

Answer 1

The Correct Option is A

Concept: Different milk tests are designed to evaluate pasteurization efficiency, stability, and quality.

Step 1: Phosphatase Test.

• Detects presence of alkaline phosphatase enzyme
• Used to verify proper pasteurization

Step 2: Turbidity Test.

• Used for UHT milk verification
• Indicates protein denaturation

Step 3: Alcohol-Alizarin Test.

• Determines heat stability of milk
• Color change indicates acidity and instability

Step 4: Platform Test.

• Performed at reception dock
• Evaluates quality of incoming milk

Step 5: Matching.
\[ A \rightarrow II,\quad B \rightarrow III,\quad C \rightarrow IV,\quad D \rightarrow I \] Conclusion: Option (1) correct.
