Question

Lactic acid bacteria (LAB) grow in milk and convert it to curd and also improve its nutritional quality by increasing:

• A. Vitamin A
• B. Vitamin B${}_{12}$
• C. Vitamin B${}_{16}$
• D. Vitamin C and A

Answer 1

The correct option is B Vitamin B${}_{12}$

Microorganisms such as Lactobacillus and others commonly called Lactic Acid Bacteria (LAB) grow it milk and convert into curd. During growth, the LAB produces acids that coagulate and partially digest the milk proteins. A small amount of curd added to the fresh milk as inoculums or starter contains millions of LAB, which multiply at a suitable temperature, thus converting milk to curd, which also improves its nutritional quality by increasing vitamin B${}_{12}$.
