Question

Fresh milk has a pH of 6. How do you think the pH will change as it turns into curd?

• A. pH will reduce
• B. pH will increase
• C. It become same as milk
• D. None of these

Answer 1

The correct option is A pH will reduce

The pH of fresh milk is 6 which is acidic in nature. This milk is converted to curd by the action of bacteria which further increases the acidity of the curd and decreases its pH value from 6 and it becomes less than 6. The acidic strength increases on going down the pH scale from 7 to 1.
