Rennet is a complex of enzymes used in the production of cheese, helping to coagulate milk and separate the curds from the whey. The key enzyme in rennet is chymosin, also known as rennin. This enzyme specifically targets and breaks down the kappa-casein protein in milk, leading to the formation of a solid curd. Traditionally, rennet is derived from the lining of the fourth stomach chamber (the abomasum) of young, unweaned calves. This source is known as animal rennet. However, there are also microbial rennets (derived from fungi or bacteria), vegetable rennets (from plants like thistle, nettle, or fig), and genetically engineered or fermentation-produced chymosin (FPC) available. Rennet is essential for making most hard cheeses, such as cheddar, parmesan, and mozzarella, as well as some soft cheeses.
