Question

What is the best pH range for the growth of most bacteria in milk and milk products?

• A. 5 to 6
• B. 6.0 to 7.7
• C. 8 to 9
• D. 3 to 5

Hint:

Regular pH monitoring of milk products helps maintain their quality and safety standards.

Answer 1

The Correct Option is B

Most bacteria grow optimally in a neutral to slightly acidic environment. The pH range of 6.0 to 7.7 is ideal for bacterial growth in milk and milk products. This range corresponds to the natural pH of fresh milk, making it conducive to microbial activity. Beyond this range, either an acidic or alkaline environment inhibits bacterial growth. Monitoring pH levels in dairy products ensures their safety and helps in preventing spoilage.
