Rennet /ËrÉnÉ¨t/ is a complex of enzymes produced in the stomachs of ruminant mammals. Rennet is used in the production of most cheeses. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. This helps young mammals digest their mothers' milk.ennet can also be used to separate milk into solid curds for cheese making and liquid whey. In addition to chymosin, rennet contains other important enzymes such as pepsin and a lipase. The mammal must be killed to obtain its rennet. Non-animal alternatives for rennet are suitable for consumption by vegetarians.
