Question

How can does the process of conversion of milk into yoghurt occur?

Answer 1

Milk is converted into curd or yogurt by the process of fermentation. Milk consists of globular proteins called casein. The curd forms because of the chemical reaction between the lactic acid bacteria and casein. During fermentation, the bacteria use enzymes to produce energy (ATP) from lactose.

Answer 2

Heya Friend,

Here is yoyr answer,

Fresh milk is fermented using lactic bacteria starters or “cultures”: Lactobacillus bulgaricus and Streptococcus thermophilus. The bacteria are added to heated, pasteurized, homogenized milk, and the milk is then incubated at a specific temperature to maximize the activity of the bacteria.

The bacteria convert the lactose to lactic acid, which thickens the milk and gives it the tangy taste characteristic of yogurt.

The yogurt is then cooled and can be flavoured with fruit, sugar, other sweeteners or flavourings. Stabilizers, such as gelatin, may also be added.

Hope it helps you.
