Question

Bactofugation of milk prior to cheese making prevents.

• A. Souring of milk
• B. Late blowing in cheese
• C. Early blowing in cheese
• D. Hold development during storage

Hint:

Clostridium spores = Late blowing defect → removed by bactofugation.

Answer 1

The Correct Option is B

Concept: Bactofugation is a process used in dairy industry to remove bacteria and spores from milk using centrifugal force.

Step 1: Understanding bactofugation.

• Milk is subjected to high-speed centrifugation
• Heavier bacterial spores are separated

Step 2: Problem in cheese making.
Clostridium spores:
• Survive pasteurization
• Cause gas formation in cheese
• Lead to “late blowing” defect

Step 3: Effect of bactofugation.

• Removes spores
• Prevents gas formation
• Improves cheese quality

Step 4: Evaluating options.

• Sour milk → Not main function
• Late blowing → Correct
• Early blowing → Caused by coliforms
• Hold development → Irrelevant

Step 5: Conclusion.
Thus, bactofugation prevents late blowing.
