Vegetable enzymes, also known as vegetable rennet, are derived from plants such as thistle, melon, safflower, and fig leaves, and are commonly used in cheese production as a vegetarian-friendly alternative to animal rennet, which is made from the stomachs of young animals. Vegetable enzymes are considered a vegetarian source because they do not contain animal products. However, it's important to note that some cheeses are made without any form of rennet, using acids like vinegar or citrus juice to curdle the milk instead. In addition, vegan cheeses are manufactured without using animal milk, instead opting for plant-based alternatives such as soy, wheat, rice, or cashew, which are coagulated with acids or other methods.

What You'll Learn
Vegetable enzymes are vegetarian-friendly and derived from plants
Vegetable enzymes are suitable for vegetarians as they are derived from plants and do not contain animal products. This means that no animal parts end up in the cheese. Vegetable rennet is made from plants such as thistle, melon, safflower, fig leaves, and fig tree bark. Certain cultures have also used nettles, cardoon thistles, mallow, and ground ivy or creeping Charlie. Thistle is commonly used in the Mediterranean to make cheeses such as feta, mozzarella, and ricotta.
Some cheeses are made without any form of rennet at all, including softer cheeses like cream cheese, paneer, rubing, and other acid-set varieties. These are made by coagulating milk with an acid like vinegar or citrus to curdle the milk.
Vegetarian rennet can also be made using microbes, which is called microbial rennet. This is made from the products of fungi or bacteria, such as molds like rhizomucor miehei. These molds are made in controlled conditions in a fermenter and then purified and concentrated to make them safe for human consumption. Microbial enzymes may increase the bitterness of cheese, especially mature varieties, and are therefore more commonly used by high-yielding cheese manufacturers.
Fermentation-produced chymosin (FPC) is another vegetarian-friendly option, which can be used to make kosher and halal cheeses. This method is more often used in industrial cheesemaking in North America and Europe due to its lower cost compared to animal rennet.

Rennet is traditionally made from the stomachs of young animals
Rennet is a complex set of enzymes that curdle the casein in milk, separating it into solid curds and liquid whey. This process is essential in the production of cheese, particularly harder varieties such as mozzarella, parmesan, or cheddar. Rennet is traditionally sourced from the stomachs of young ruminant mammals, such as goats and calves. The inner mucosa of the fourth stomach chamber, or abomasum, is removed and treated to extract rennet, which contains the key enzyme chymosin.
The use of animal rennet has been largely replaced by more modern processes and alternative sources of rennet. This shift is partly due to the limited availability of ruminant stomachs and the desire for vegetarian-friendly cheese options. Traditional animal rennet is now less common, with less than 5% of cheese in the United States made using this method.
One alternative to animal rennet is microbial rennet, produced by microorganisms such as fungi, yeast, or mold. These microbes are genetically modified to produce the same enzymes found in the stomach of a ruminant animal, resulting in a product that is safe for vegetarians. Microbial rennet, also known as fermentation-produced chymosin (FPC), has been commercially available since 1990 and is widely used today. FPC offers several advantages over animal rennet, including higher production yield, better curd texture, and reduced bitterness.
Another source of rennet is plants, with various plant-based coagulants available. Thistle plants, such as artichokes and nettles, are commonly used to produce plant rennet, particularly in the Mediterranean and Portugal. Other plants with coagulating properties include fig juice, dried caper leaves, mallow, and ground ivy. These plant-based alternatives have been explored since Roman times, as mentioned by Homer in the Iliad.

Rennet can also be made from plants, like thistle, or microbes
Rennet is a key ingredient in cheesemaking, separating milk into solid curds and liquid whey. It is traditionally derived from the stomachs of young animals, typically calves, though also lambs and goats. However, rennet can also be made from plants, like thistle, or microbes.
Vegetable rennet is derived from plants and is considered a vegetarian cheese enzyme as it does not contain animal products. Thistle is a common source of vegetable rennet, particularly in the Mediterranean, where it is used to make cheeses like feta, mozzarella and ricotta. Other plants that can be used to make rennet include fig tree bark, nettles, cardoon thistles, mallow and ground ivy or creeping Charlie.
Microbial rennet, also known as vegetarian rennet, is created in a lab and is sometimes derived from mushrooms or moulds, such as rhyzomucor miehei. This type of rennet is made by growing the moulds in controlled conditions in a fermenter, then purifying and concentrating them so that they are safe for human consumption. Microbial rennet is often preferred by cheese manufacturers as it is less expensive than animal rennet and can produce a higher yield. However, it may increase the bitterness of cheeses, particularly mature ones.
Genetically modified enzymes are another option for vegetarian rennet. These enzymes are less bitter than microbial enzymes and are also less expensive to produce. They are recognised as vegetarian-friendly by organisations like The Vegetarian Society.

Microbial rennet is made from fungi or bacteria
Rennet is a complex set of enzymes traditionally produced in the stomachs of ruminant mammals and used to separate milk into solid curds and liquid whey during the production of cheese. However, animal rennet has become less common, with less than 5% of cheese in the United States being made using it today. This has led to the use of alternative sources of rennet, such as vegetable rennet, microbial rennet, and fermentation-produced chymosin.
Microbial rennet, in particular, is derived from fungi or bacteria that can produce a coagulating enzyme. It is considered vegetarian-friendly and has several advantages over animal rennet, including bulk production, unlimited availability, lower cost, and no risk of disease transmission. The most widely used microbial rennet is produced by the fungus Rhizomucor miehei, also known as R. miehei. This fungus is found in many outdoor locations and is used to make a variety of cheeses, including soft and short-hold cheese varieties.
Other examples of fungi used to produce microbial rennet include Aspergillus niger, Kluyveromyces lactis, R. pusillus, A. oryzae, and Irpex lactis. These microorganisms are widely used for rennet production in cheesemaking. Additionally, microbial rennet can be produced by fermentation, which is currently the most commercialized method for producing rennet.
The use of microbial rennet from fungi or bacteria offers a suitable alternative to animal rennet, providing benefits such as higher production yield, better curd texture, and reduced bitterness. It is important to note that microbial rennet is different from vegetable rennet, which is derived from plants with coagulating properties, such as fig, thistle, and mallow.

Some cheeses are made without rennet, using acid or vinegar
Vegetable rennet, or vegetable enzyme, is derived from plants that naturally produce the enzyme chymosin, which is necessary for cheesemaking. These plants include artichokes, thistle, nettles, cardoon thistles, mallow, ground ivy, and creeping Charlie. Thistle is commonly used in the Mediterranean to make feta, mozzarella, and ricotta.
Vegetable rennet is a comparatively new product and technique in cheesemaking. It is a great option for making vegetarian-friendly cheeses and cutting back on animal products. However, it is important to note that animal rennet and vegetable rennet are not interchangeable.
Soft cheeses such as chevre, queso, and paneer can be made using lemon juice, vinegar, or citric acid. For mozzarella, a small amount of acid is needed in addition to rennet. The type of acid used can impact the coagulation process, with vinegar or citric acid causing quick curdling and rennet causing slow curdling.
