Question

What is the main function of lactic acid produced by LAB in milk?

विकल्प

• To develop a soft texture

• To increase the vitamin B₁₂ content

• To coagulate and partly digest milk proteins

• To produce carbon dioxide gas

Answer 1

The lactic acid produced by LAB causes coagulation and partial digestion of milk proteins, converting the milk into curd. This acidification is the key chemical process that transforms the liquid milk into the solid curd product, while also improving its nutritional value and preservative properties.
