Is Rennet vegan?

Q: Is Rennet vegan?

Rennet is not reliably vegan. It can come from plant or animal sources. A supplier declaration is needed to confirm the origin. Rennet is a complex of enzymes, primarily chymosin, used in cheesemaking to coagulate milk into curds and whey. Traditionally extracted from the stomach lining of young ruminants, it can also be produced from microbial or fungal sources, or via recombinant biotechnology.
