Question

In golden days, cheese was prepared by
A. Aspergillus
B. Rennet enzymes
C.Clostridium bacteria
D.None of the above

Answer 1

Hint: Cheese is a dairy product and is made from milk by the coagulation of milk casein. In golden days the cheese was made from the enzyme present in the stomachs of animals like sheep, camel.

Step by step answer:Cheese is a dairy product that is made from the milk by coagulation of the milk casein. The origin of cheese was around when the sheep were domesticated. In ancient times animal skins and the inflated organs were used as storage vessels for the food. Rennet is an enzyme that is derived from the stomachs of the calves, goats, and the lambs, it is used for the production in cheese as the chymosin which is present in it is a protease which curdles the casein in milk and is a key component. Casein is a milk protein, the cleavage causes the caseins to stick to the other cleaved casein molecules and it forms a network which clusters better in the presence of the calcium and the phosphate and thus it is used in the process of cheese making which is from the calcium phosphate that is the poor goat milk.
Hence, the correct option is ‘B’.

Note: CThe process of cheese was accidentally discovered when the milk was stored in a container that was made from the stomach of an animal and it resulted in the milk to curd and whey from the rennet enzyme.
