Question

What is rennin?

Answer 1

Hint: Rennin is also known as the chymosin enzyme. This enzyme is present in the ruminant animals mostly. It is present on the lining of the abomasum in the newborn ruminant animals. The ruminant animals like cows have rennin present in their stomach when they are in the young stage.

Complete answer:
Rennin is the enzyme which is known to coagulate the milk and it is also used for making cheese. Rennin is the milk digesting enzyme mostly present in the infants of cows. It is the protein-digesting enzyme that helps in the curdling of the milk and transforms the milk protein into casein. It is found in the fourth stomach of the ruminant animals. The presence of this enzyme helps in the retaining of the milk in the stomach and extends its absorption period. In cheese producing industries this rennin is used to thicken the milk and make cheese. Even curds are formed from them using the rennin as the thickening agent. Rennin is an important enzyme in the infants of the ruminant’s animals as they are the source of the milk digestion. The infants are fed milk in the initial months of their life as they are unable to eat other complex food. The milk produced by the cows should be used by their infants as it is produced for them to feed on. The milk produced by them is not for human consumption. The cow milk alternatives that one can feed on are soy milk, coconut milk, or the oat milk which has higher nutrition than the cow milk.

Note: The rennin is also known as the chymosin enzyme. It is found only in the infants of the ruminant animals. It is missing in adults. Rennin is present in the infants only as it is needed by them to digest the milk they consume.
