Rennet

Caution

Enzyme

Rennet is an enzyme used in cheesemaking, traditionally derived from the stomach lining of young mammals, but it can also be sourced from plants and microbes.

What is Rennet?

Rennet is a complex set of enzymes that plays a crucial role in the cheesemaking process by coagulating milk, leading to curd formation. Traditionally, rennet is obtained from the fourth stomach of unweaned calves, but it can also be sourced from microbial and plant origins, such as fungi and thistle plants, making it suitable for vegetarians and vegans. This distinction is important for those following specific dietary restrictions.

Why People Avoid Rennet

Many people, particularly those following a vegan diet, avoid rennet because traditional animal rennet is derived from the stomach lining of unweaned calves, making it an animal product. Ethical considerations and dietary preferences lead individuals to seek non-animal-derived rennet, which is made using microbial fermentation or extracted from plants, thus aligning better with vegetarian and vegan principles.
