Many consumers are surprised to learn that traditional mozzarella cheese is made using rennet, an enzyme complex often derived from the stomachs of young calves. However, the answer to "Does mozzarella have renin?" is not a simple yes or no, as modern cheesemaking uses various coagulants. Today, you can find a wide range of mozzarella options that are suitable for vegetarians.

An enzyme called rennet is a key ingredient in cheesemaking, used for milk coagulation. Rennet has historically come from the stomachs of young ruminant animals. Today, cheeses are made with animal, microbial, or plant-based rennet.

Over 90% of factory-made cheese worldwide now utilizes microbial or fermentation rennet, making many cheeses suitable for vegetarians. However, whether a cheese is truly vegetarian depends entirely on the type of coagulating enzyme, known as rennet, used during production.

According to Dairy Management Inc., over 98% of US-produced cheeses use non-animal rennet, making them suitable for vegetarians and pescatarians. However, not all cheese is created equal, and pescatarians must consider the ingredients to ensure their choice aligns with their diet.
