Milk contains a protein called casein. This protein provides milk with its characteristic white colour. It is of high nutritional value because it contains all the essential amino acids required by the man's body.

Lactic acid bacteria present in the curd that is used as the culture, cause coagulation of milk casein and thus, convert it into curd.
