Question

Shreya, Alina and Tia were assigned with the task of making curd by their Science teacher. The three girls followed the procedures given below: -a. Shreya-One cup of cold milk + two tablespoon of curd b. Alina-One cup of hot milk + two tablespoon of curd c. Tia -One cup of warm milk + two tablespoon of curd All the three of them left theirbowls undisturbed for 8 hours.Who among the three would be successful in obtaining a well-set curd. Justify your answer giving reasons.

Answer 1

Tia will obtain because for making curd lactobacillus should act and produce lactic acid. They are inactive at very low temperatures or at very high temperatures. They become active only at a specific range of temperature which is given by warm milk.

Answer 2

Heya user,

The prodedure followed by Tia will successfully formed the curd as Curd is made by the bacteria called lactobacillus. This bacteria develops and recreates to make curd in the warm milk only.

On the off chance that the milk is excessively hot or cool, the bacteria won't have the capacity to work legitimately and the curd won't beformed.

Hope this will help you ☺☺
