Question

write the process of making curd from milk?explian the changes that takes place in the milk

Answer 1

1️⃣Milk is converted into curd or yogurt by the process of fermentation.

2️⃣Milk consists of globular proteins called casein.

3️⃣The curd forms because of the chemical reaction between the lactic acid bacteria and casein.

4️⃣During fermentation, the bacteria use enzymes to produce energy (ATP) from lactose.

5️⃣The byproduct of ATP production is lactic acid.

6️⃣Lactic acid acts on the globular proteins present in the milk and denatures them.

7️⃣This denaturation destroys the tertiary and quaternary structures of proteins and the globular proteins are converted into fibrous proteins thus giving a thick texture to the milk due to coagulation of the proteins.
