Parmesan cheese, or Parmigiano-Reggiano, is a specialty hard cheese made from unpasteurized cow's milk. It is produced using specific, traditional methods and ingredients, including calf rennet, an enzyme derived from the stomach of young ruminant mammals. Rennet is used to coagulate the milk and separate the curds from the whey, a process that occurs naturally in newborn animals to curdle milk for better nutrient absorption. While chymosin, the protease found in rennet, can be sourced from plants and fungi, traditional Parmesan production methods dictate the use of animal-derived rennet, making the cheese unsuitable for vegetarians.

What You'll Learn
Parmesan is not vegetarian
Parmesan, or Parmigiano-Reggiano, is a specialty Italian hard cheese made from unpasteurized cow's milk, heavily salted and aged for at least 12 months to cultivate its unique flavor. However, despite being made from cow's milk, it is not strictly vegetarian.
Parmesan cheese is traditionally made with animal enzymes. Rennet, an enzyme used to set cheese, is the culprit behind Parmesan's non-vegetarian status. Rennet is a complex combination of enzymes produced in the stomachs of young ruminant mammals, such as calves, goats, or lambs. In newborn animals, chymosin, a type of rennet, curdles the milk they ingest, aiding in better nutrient absorption. This process is mimicked in cheese-making, where chymosin is added to create curds.
While chymosin can be sourced from plants and fungi, traditional production methods of Parmesan call for animal-derived chymosin. Rennet is extracted by taking a piece of an animal's stomach and dropping it into saltwater or whey with an acidic ingredient to draw out the enzymes. This process is necessary to create a true Parmigiano Reggiano cheese, as defined by the European Union.
The inclusion of rennet in Parmesan has sparked dismay among vegetarians, as it disqualifies the cheese from being considered vegetarian-friendly. The use of animal-derived rennet in cheese-making is not limited to Parmesan, as other varieties like Gorgonzola, Pecorino Romano, Camembert, Gruyère, and Manchego also traditionally contain this ingredient.
In conclusion, Parmesan cheese is not vegetarian due to the use of animal-derived rennet in its traditional production methods. This discovery may come as a surprise to vegetarians who have been consuming Parmesan, believing it to be safe, and highlights the importance of examining the production methods of seemingly vegetarian foods.

Rennet is made from calves' stomachs
Rennet is a complex combination of enzymes produced in the stomachs of ruminant mammals, such as calves. It is an essential ingredient in the production of Parmesan cheese, as it helps coagulate the milk and separate the curds from the whey. Rennet is traditionally derived from animal sources, and its inclusion in Parmesan means that the cheese is not considered vegetarian-friendly.
The process of extracting rennet involves taking a piece of the stomach of a calf and dropping it into saltwater or whey paired with an acidic ingredient. This mixture helps to "draw out the enzymes" needed for cheese production. While chymosin, a type of protease found in rennet, can be sourced from plants and fungi, traditional Parmesan production methods dictate the use of animal-derived rennet.
In newborn calves, chymosin plays a crucial role in curdling the milk they ingest, allowing for better nutrient absorption. Similarly, in cheese-making, chymosin is introduced to create curds, a necessary step in the cheese-making process.
The use of rennet in Parmesan cheese has sparked dismay among vegetarians and those concerned about animal welfare. The extraction of rennet requires harming the animal, and as a result, many people are unaware that Parmesan contains animal-derived ingredients.
To produce vegetarian cheeses, alternative sources of rennet are used, such as fungal, bacterial, or genetically modified microorganisms. However, traditional Parmesan cheese, or Parmigiano Reggiano, as it is officially known, relies on animal-derived rennet as a key ingredient, contributing to its distinctive flavor and texture.

Rennet is used to make Parmesan
Parmesan, or Parmigiano-Reggiano, is a specialty Italian hard cheese made from unpasteurized cow's milk, heavily salted and aged for at least 12 months to cultivate its unique flavor. Rennet is used to make Parmesan. Rennet is an animal byproduct enzyme that helps coagulate the milk and separate the curds from the whey. It is a complex combination of enzymes produced by the stomachs of young ruminant mammals, like calves. In newborn animals, chymosin curdles the milk they ingest, allowing for better nutrient absorption. In cheese-making, chymosin is introduced to create curds. Rennet is extracted by taking a piece of an animal's stomach and dropping it into saltwater or whey paired with an acidic ingredient to draw out the enzymes.
Parmesan must be made using chymosin, or rennin, a protease found in rennet. While chymosin can technically be sourced from plants and fungi, the traditional production methods of Parmesan dictate that the ingredient is animal-derived. Rennet is a must to classify the cheese as a true Parmigiano Reggiano, along with cow's milk and salt, according to the European Union's legal definition.
Parmesan is not considered suitable for vegetarians because of the inclusion of rennet. Vegetarians may also want to avoid other cheeses that traditionally contain rennet, such as Gorgonzola, Pecorino Romano, Camembert, Gruyère, and Manchego.
The production of Parmesan is not animal-friendly, and calves die for the cheese as one of their stomachs is used for solidifying it.

Rennet is an enzyme that curdles milk
In Parmesan cheese production, rennet is used to curdle the milk and separate the curds from the whey. Rennet is a crucial ingredient in the production of Parmigiano Reggiano, the protected designation of origin (PDO) for cheeses produced in specific Italian provinces under Italian and European law.
The use of rennet in cheese-making has come under scrutiny due to its animal origin. Rennet is extracted from the stomachs of young animals, which has raised concerns among vegetarians and those concerned about animal welfare. While chymosin, a protease found in rennet, can be sourced from plants and fungi, traditional Parmesan production methods dictate the use of animal-derived rennet.
The process of extracting rennet involves taking a piece of the animal's stomach and soaking it in saltwater or whey with an acidic ingredient to draw out the enzymes. This traditional method of cheese-making has been a source of dismay for those who are unaware of the animal-derived ingredient in their beloved Parmesan.
While Parmesan is widely known for its distinctive flavor and texture, the use of rennet in its production has sparked discussions about the suitability of the cheese for vegetarian diets and raised questions about animal welfare in the dairy industry.

Calves are killed for Parmesan
Parmesan, or Parmigiano-Reggiano, is a specialty Italian hard cheese made from unpasteurized cow's milk, heavily salted, and aged for at least 12 months to cultivate its unique flavor. It is made using traditional methods and ingredients, which include specific animal ingredients.
Parmesan is not vegetarian-friendly because it contains rennet, an enzyme that helps coagulate the milk and separate the curds from the whey. Rennet is a complex combination of enzymes produced in the stomachs of young ruminant mammals, like calves. To obtain rennet, a piece of the animal's stomach is dropped into saltwater or whey with an acidic ingredient to draw out the enzymes. This process is not possible without harming the animal.
Calf rennet is added to the mixture during the production of Parmesan cheese. The mixture is then left to curdle for 10-12 minutes before being broken up mechanically into small pieces.
As a result, calves are killed to obtain rennet, an essential ingredient in the production of Parmesan cheese. The use of animal-derived rennet in Parmesan production means that the cheese cannot be considered suitable for vegetarians.
