Question

Amount of which vitamin increases after conversion of milk into curd?

(A) Vitamin B₁₂

(B) Vitamin A

(C) Vitamin C

(D) Vitamin B₆

Answer 1

Correct option is (A) Vitamin B₁₂

Microorganisms such as Lactobacillus and others commonly called Lactic Acid Bacteria (LAB) grow in milk and convert it into curd.

During growth, the LAB produce acids that coagulate and partially digest the milk proteins. A small amount of curd added to the fresh milk as inoculums or starter contain millions of LAB, which at suitable temperature multiply, thus, converting milk to curd, which also improves its nutritional quality by increasing vitamin-\(B_{12}\) .

Answer 2

The correct option is (A) Vitamin B₁₂
