Cheese Culture Enzymes

Cheese culture enzymes are a complex mixture of enzymes, primarily rennet, used in cheesemaking. They are typically derived from the stomach lining of young ruminant animals (like calves) or produced through microbial fermentation using genetically modified microorganisms. These enzymes help coagulate milk proteins, forming the curd that is essential for cheese production.

Manufacturers add cheese culture enzymes to coagulate milk proteins and produce cheese. They are the key ingredient responsible for transforming liquid milk into solid cheese curds. They are found in a wide variety of cheeses and cheese-flavored products.

Enzymes used in food production are generally considered safe and are subject to FDA regulation. The enzymes used in cheese cultures are typically GRAS (Generally Recognized As Safe) or approved food additives. JECFA has evaluated enzymes used in food processing. At the levels found in food, these enzymes are not expected to pose health risks. There are no widespread health controversies associated with their use.
