Rennin, also known as chymosin, is an enzyme that can be easily found in the rennet. It is usually produced by the 4 th stomach chamber of the cows, called abomasum. Infants have gastric chief cells that produce rennin in order to clot the milk and promote a much better absorption.hus, the stomach can digest and absorb milk proteins, which is extremely important for the human body. In case the stomach doesnât produce enough rennin, the milk is not digested properly and the calcium cannot be absorbed in the bones and body. So, young mammals are the only ones that can produce rennin enzymes.
