What is Rennet?

Rennet is a complex set of enzymes produced in the stomachs of ruminant mammals, traditionally derived from the lining of calves' stomachs. It plays a crucial role in the cheese-making process by coagulating milk, leading to curd formation.

Rennet is primarily used to make cheeses by splitting milk proteins, allowing them to form solid curds and leaving the liquid whey behind. While animal-derived rennet is traditional, microbial and plant-based alternatives are available for vegetarians. Health evidence mainly concerns its role in digestion rather than direct health impacts from consumption.

When spotted on labels, consumers might consider whether the rennet is animal-based, microbial, or plant-based, depending on dietary preferences and ethical considerations.

Commonly found in: Cheese, Dairy desserts, Processed cheeses
