Question

How does the process of conversion of milk into yogurt occur?

Answer 1

Process of conversion of milk into yogurt:

1. The conversion of milk to yogurt is an endothermic process.
2. The process of fermentation, specifically lactic acid fermentation, transforms milk into yogurt.
3. This occurs in an anaerobic environment, where oxygen is not required.
4. Because milk contains casein, a globular protein, it gets turned into yoghurt.
5. The lactobacillus bacteria, which transforms lactose into lactic acid, can also be found in milk.
6. The pH of milk lowers as a result of the chemical reaction that happens between casein and lactic acid due to the presence of enzymes, causing it to coagulate and release energy.
7. Yogurt is the result of this process.
