Parmesan cheese is a beloved staple in many kitchens, but is it vegetarian? The answer is complicated. While Parmigiano-Reggiano, the style of cheese that Parmesan is modelled after, is not vegetarian, some versions of Parmesan cheese can be vegetarian. The difference lies in the use of rennet, an enzyme derived from the stomach lining of calves or other young ruminants, which is used in the production of Parmigiano-Reggiano. However, some manufacturers of Parmesan cheese use vegetable-based or microbial-based enzymes, making their products suitable for vegetarians. This topic highlights the importance of reading food labels and understanding the ingredients in our food.

Rennet: a coagulant derived from animal stomach lining
The traditional method of making Parmesan cheese, like many other cheeses, involves the use of rennet, a complex mixture of enzymes produced in the stomachs of ruminant animals. These enzymes play a crucial role in the cheese-making process, specifically in the coagulation of milk. While there are alternative sources of coagulating agents used in cheese production, such as microbial transglutaminase or vegetable-based rennet, traditional Parmesan cheese typically relies on animal-derived rennet. This raises the question of whether Parmesan cheese is suitable for vegetarians, given that it involves the use of an animal product.
Rennet is a crucial component in cheese production, and its primary function is to curdle milk, initiating the separation of curds and whey. The curds are then processed further to create cheese, while the whey may be used in other dairy products or as a nutritional supplement. Calf rennet, in particular, has been highly valued in the cheese-making industry due to its effectiveness and the unique characteristics it imparts to the final cheese product. However, the use of animal-derived rennet presents a challenge for vegetarians and those looking to avoid animal-based products.
The stomachs of ruminant animals, such as calves, contain multiple enzymes that break down milk for digestion. These enzymes are collectively known as rennet or rennin. Traditionally, obtaining rennet involved slaughtering young, unweaned calves and extracting the enzymes from their stomach linings. This practice raised ethical concerns among vegetarians and those promoting animal welfare. As a result, alternative sources of rennet have been developed, but traditional Parmesan cheese producers often stick to the traditional method, considering it a key factor in the distinctive flavor and texture of their cheese.
Animal-derived rennet is obtained from the inner mucosa layer of the stomach, which is where the enzymes responsible for milk coagulation are produced and secreted. These enzymes act on the proteins in milk, causing them to aggregate and form a solid mass, or curd, which can then be further processed into cheese. While the use of animal-derived rennet is traditional in Parmesan cheese-making, it's important to note that modern alternatives, such as microbial rennet and vegetable-based coagulants, can also be used to produce cheese suitable for vegetarians.
The process of extracting rennet from animal stomachs has been optimized to ensure efficiency and maximize yield. The stomachs are carefully cleaned and prepared, and the enzymes are extracted using a brine solution. This extraction process results in a liquid or paste containing the active enzymes. The solution is then typically concentrated and purified to create a more potent form of rennet that can be easily stored and transported. The use of animal-derived rennet has been a longstanding tradition in cheese-making, but with increasing awareness of vegetarian and vegan diets, as well as animal welfare concerns, there is a growing trend toward alternative coagulants.
In summary, rennet is a crucial component in the cheese-making process, particularly in the production of traditional Parmesan cheese. Its source, derived from the stomach lining of ruminant animals, has been a matter of concern for vegetarians and those seeking animal-product alternatives. While traditional Parmesan cheese often relies on animal-derived rennet, modern alternatives offer vegetarian-friendly options without compromising on flavor or texture. The use of rennet remains a key factor in the unique characteristics of many cheeses, but with a growing number of consumers seeking vegetarian options, the demand for alternative coagulants is also on the rise.

Vegetarian alternatives: some Parmesan is made with microbial or vegetable rennet
Parmesan cheese is not always vegetarian. While some Parmesan cheese is made with microbial or vegetable rennet, which is suitable for vegetarians, other Parmesan cheese is made with animal rennet, derived from the inner lining of the fourth stomach of calves, goats, or lambs. This non-vegetarian variety is the traditional way of making Parmigiano-Reggiano, the style of cheese that Parmesan is modelled after. According to European Union law, Parmigiano-Reggiano must contain animal rennet. However, products labelled simply as Parmesan can be made with vegetarian rennet.
In the US, there are many brands that make Parmesan cheese without animal rennet, and some British cheeses are also being made and labelled as vegetarian. In the US, Trader Joe's and Whole Foods both label the source of rennet used in their generic-brand cheeses, and many of these are vegetarian. Some vegetarian Parmesan brands include Organic Valley Shredded Parmesan, BelGioioso Vegetarian Parmesan, and Kraft Grated Parmesan, although the latter occasionally contains lipase, which is animal-derived. Other vegetarian-friendly brands include Cabot, Lucerne (white cheeses only), and Laughing Cow.
While it may be harder to find vegetarian Parmesan in Europe, it is not impossible. In Portugal and Spain, some traditional sheep's cheeses, including La Serena and Zimbro, use vegetarian thistle rennet, and some Iberian cheeses like Azeitão are traditionally made using plant rennet. In the UK, some supermarkets offer alternatives to animal rennet, and in Germany, a company was forced to rename a cheese called Parmesello, suggesting that true Parmesan must contain animal rennet.
When shopping for vegetarian Parmesan, it is important to read the labels carefully. While some products will clearly state that they use "vegetarian enzymes", "vegetable rennet", "microbial enzymes", or "non-animal enzymes", others may not specify the source of their rennet. In the US, cheesemakers are not required to specifically label animal rennet, so it is worth checking the company's FAQ page or asking a knowledgeable cheesemonger for advice.

Parmigiano Reggiano: the traditional Italian Parmesan is not vegetarian
Parmesan cheese is a general term with multiple interpretations. Authentic Italian Parmesan, or Parmigiano Reggiano, is a PDO (Protected Designation of Origin) cheese. This means that it must be produced in specific regions of Italy, such as Parma, Reggio Emilia, Modena, and Bologna, and made using traditional methods. These methods include using milk produced in these regions and feeding the cows locally grown forage.
Parmigiano Reggiano is crafted from only three ingredients: rennet, salt, and raw, unpasteurized milk. The rennet used in Parmigiano Reggiano is derived from the inner lining of the fourth stomach of calves, usually slaughtered for veal. The calf stomachs are ground and soaked in an enzyme extraction solution, and the end product is not vegetarian by most standards. While all cheeses labeled Parmigiano Reggiano contain animal-derived rennet, some Parmesan cheeses do not.
In the US, there are many brands that make Parmesan cheese without animal rennet, and there are also some vegetarian versions of European cheeses on the market. Stores like Whole Foods sell clearly labeled Parmesan cheese alternatives made with vegetarian enzymes. When in doubt, it is best to check the labels to ensure that the product is truly vegetarian.
While it is possible to find vegetarian Parmesan cheese at the grocery store, Parmigiano Reggiano, the traditional Italian Parmesan, is not vegetarian.

Food labels: it's important to check the ingredients list for enzymes or rennet
Parmesan cheese is a beloved staple in many kitchens, but vegetarians may be surprised to learn that their favourite cheese may contain animal products. The reason for this is the use of rennet, which is usually derived from the stomach lining of a young grazing animal, such as a calf. This is an issue for vegetarians because rennet is pretty crucial to the Parmigiano-Reggiano production process.
However, there is some good news for vegetarians who love Parmesan. Firstly, while traditional Parmigiano-Reggiano is not vegetarian, it is possible to find vegetarian Parmesan cheese at the grocery store. For instance, Organic Valley Shredded Parmesan makes a vegetarian-friendly version, and producers like BelGioioso also have their own vegetarian versions. In addition, some stores like Whole Foods sell clearly labelled parmesan cheese alternatives made with vegetarian enzymes.
Furthermore, while animal rennet is more commonly used in European cheeses, there are more and more vegetarian rennet cheeses on the market. In fact, Chad Galer, the vice president of food safety and product research at the Dairy Management Inc., estimates that more than 98% of rennet used in US-produced cheeses is from non-animal sources. This is partly due to a cultural trend toward plant-based eating, but also because non-animal rennet is cheaper for cheesemakers and makes the final product kosher.
So, what is a hungry vegetarian who loves Parmesan to do? Well, it's important to check the ingredients list for enzymes or rennet. If you see ""enzymes" on the food label, this could refer to either animal, plant, or microbial enzymes, so be sure to check. If you see "rennet", this is most likely animal rennet, which is not vegetarian. However, if you see "microbial enzymes", “vegetable rennet”, or "vegetarian rennet", the cheese should be vegetarian-friendly.
In addition to checking the ingredients list, you can also look for a kosher label on cheese products, which means that the product did not interact with meat. And, if you're ever in doubt, you can always opt for a vegan alternative. With the revolution in plant-based alternatives, you may be pleasantly surprised by how decent a vegan imitation of your favourite cheese can taste.

Taste: some say vegetarian Parmesan tastes different
The use of animal rennet in the production of Parmesan cheese is a concern for vegetarians. Rennet is an enzyme used to clot milk, and it is traditionally derived from the inner lining of the fourth stomach of calves, goats, or lambs. This means that Parmigiano-Reggiano, which must be produced in specific Italian regions and according to traditional methods, is not vegetarian.
However, the term "Parmesan" can also refer to similar cheeses that are not produced in these regions or according to these methods. In the US, there are many brands that make parmesan cheese without animal rennet, and some commenters note that they have found vegetarian Parmesan to taste the same as non-vegetarian Parmesan.
On the other hand, some sources claim that vegetarian Parmesan does have a noticeably different flavor. This may be because non-animal rennet alternatives, such as vegetable rennet derived from plants, are fussier to work with and may impart a subtly different flavor profile.
While some vegetarians may be comfortable consuming animal rennet, others may prefer to seek out vegetarian Parmesan or alternative cheese options. Some popular alternatives to Parmesan include nutritional yeast, which has a similar flavor profile, and Gran Kinara cheese, a vegetarian alternative.
