Question

Which enzyme converts milk into curd ?

Answer 1

When pasteurized milk is heated to a temperature of 30-40 °C, or even at room temperature or refrigerator temperature, and a small amount of old curd is added to it, the lactobacillus in that curd starts to grow. This converts the lactose into lactic acid, which imparts the sour taste to curd

Answer 2

Lactobacilllus is the bacteria that converts milk to curd .
This bacteria converts the lactose present in the milk to lactase.
