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

Answer 1

The formation of lactic acid is what turns the milk into curd; therefore, it will result in the pH changing below 6.

Answer 2

The pH of milk is 6. As it changes to curd, the pH will reduce because curd is acidic in nature. The acids present in it decrease the pH.
