Many people are surprised to learn that not all cheese is vegetarian. This is because a lot of cheese contains rennet, an animal-derived enzyme that helps milk separate into curds and whey during the cheese-making process. Animal rennet is traditionally obtained from the stomach lining of ruminant animals like cows and goats, and is therefore not considered vegetarian. While some cheeses, like queso fresco and cream cheese, are made with an acidification process, most types of cheese, including cheddar, are made with animal rennet. However, it's important to note that not all cheddar cheese contains rennet, and there are vegetarian alternatives available.

What You'll Learn
Rennet is an enzyme that coagulates milk during cheese-making
Rennet is an enzyme that plays a crucial role in the coagulation of milk during cheese-making. This process, which separates the curds from the whey, is essential in the production of many types of cheese. While some cheeses can be made without rennet, using acids like lemon juice or vinegar for coagulation, many traditional cheeses, including cheddar, Swiss cheese, and mozzarella, often contain animal rennet.
Animal rennet is derived from the lining of the stomach of ruminant animals, such as cows, goats, sheep, and even pigs. It is obtained after slaughtering the animal, which is why it is not considered vegetarian. For vegetarians and those wishing to avoid animal products, the presence of rennet in cheese can be a concern. Some cheesemakers have started using microbial or vegetable rennet, which is derived from plant sources or molds, offering vegetarian-friendly options. However, it is important to note that cheesemakers are not required to specify the type of rennet used on their packaging, making it challenging for consumers to make informed choices.
The use of rennet in cheese-making has been a topic of discussion and concern for those with dietary restrictions or ethical concerns. The presence of animal rennet in cheese means that many cheeses are not suitable for vegetarians or those wishing to avoid animal-derived products. This has led to an increase in the availability of vegetarian cheese options, with some brands offering alternatives made with microbial or vegetable rennet. However, the lack of clear labeling can make it difficult for consumers to identify vegetarian-friendly cheeses.
To address this issue, some organizations, such as the Vegetarian Resource Group, provide resources and guides to help consumers identify rennet-free cheeses. Additionally, some companies, like Simply Grassfed, offer cheese made with organic animal rennet, ensuring transparency and providing options for those who prefer animal-based products. The use of fermentation-produced rennet, which is vegetarian-friendly, has also gained popularity in the cheese industry, as it closely mimics the flavor and quality of traditional animal rennet while minimizing the risk of a bitter taste.
In summary, rennet is an important enzyme in the cheese-making process, contributing to the coagulation of milk. While animal rennet has been traditionally used, the consideration for vegetarian and ethical preferences has led to the development of alternative sources, such as microbial and vegetable rennet. However, the lack of standardized labeling practices can make it challenging for consumers to make informed choices. As a result, consumers often have to rely on independent research, lists, and resources provided by organizations dedicated to vegetarian or vegan lifestyles.

Rennet is often derived from the stomach lining of calves, goats, sheep, or pigs
Rennet is an enzyme that helps coagulate the milk during the cheese-making process. It is traditionally derived from the stomach lining of ruminant animals, including calves, goats, sheep, and pigs. These animals are often slaughtered for their meat, and the use of rennet in cheese-making is considered harmful to animals, making cheese containing rennet non-vegetarian.
Cheddar cheese, being a hard cheese, often falls into the category of non-vegetarian cheeses due to the presence of animal rennet. However, it is important to note that not all cheddar cheeses contain rennet, and some may be made with alternative ingredients or processes. Some cheese varieties, such as cream cheese, cottage cheese, and Indian cheese, are typically made without rennet, providing vegetarian-friendly options.
The use of animal rennet in cheese has come under scrutiny, with many vegetarians and conscious consumers avoiding cheeses containing it. This has led to an increase in the availability of vegetarian cheese options, which use plant-based or microbial rennet. These alternatives are derived from vegetable sources or developed synthetically in a laboratory setting. However, it is worth noting that some consumers express concerns about the potential use of genetically modified organisms (GMOs) in these vegetarian alternatives.
While some countries have labeling requirements for cheese, such as the United States' FDA GRAS (Generally Regarded as Safe) regulation, it is not always mandatory to specify the type of rennet used. This can make it challenging for consumers to identify vegetarian-friendly options. To address this, various resources are available, such as websites and mobile applications, that provide lists of vegetarian cheeses and fast-food guides, helping consumers make informed choices when purchasing cheese.

Cheddar is a hard cheese that usually contains rennet
While some cheese can be vegetarian, a lot of it is not. This is because animal rennet is commonly used in the cheesemaking process, and producers are not required to specify whether they have used animal or vegetable rennet on their packaging. This can make it challenging for consumers to identify vegetarian-friendly options. However, there are some resources available, such as the Vegetarian Resource Group, which provides lists of vegetarian-friendly cheeses and fast-food options.
To make cheese vegetarian, alternative coagulants can be used in place of animal rennet. These include acids like lemon juice or vinegar, which can be used to coagulate the milk without the need for rennet. Additionally, "microbial enzymes" are widely used in the industry as they are a consistent and inexpensive coagulant. These are synthetically developed in a lab and function similarly to animal rennet.
It is important to note that some soft cheeses, such as cream cheese, cottage cheese, and Indian cheese, typically do not contain rennet as it is not usually necessary for their firming process. However, some cottage cheeses may contain gelatin, which is derived from animal sources. For those seeking vegetarian or vegan options, it is always important to carefully read the labels and do some research on the specific product or brand.

Vegetarian rennet is made from plants or microbial moulds
Animal rennet is commonly used in cheesemaking. It is derived from the lining of the fourth stomach of a young ruminant, typically a calf. However, animal rennet is not vegetarian-friendly, and many cheese lovers are surprised to learn that not all cheese is vegetarian. This has led to the development of vegetarian rennet, which is made from plants or microbial moulds.
Vegetarian rennet derived from plants is characterised by its coagulating properties. The use of plants for coagulation is quite traditional, with certain regions relying primarily on plants to coagulate their curds. For example, the Extremadura region of Spain uses the traditional "tortas" coagulated with the cardoon thistle. Other plants with coagulating properties include nettles and artichokes. The plants are soaked in water to extract a thickening enzyme similar to chymosin, which is the enzyme found in animal rennet. However, plant-based rennet can yield inconsistent results and affect the flavour of the cheese, which may be undesirable depending on the cheesemaker's intent.
Microbial rennet is another type of vegetarian rennet. It is derived from moulds that produce a coagulating enzyme similar to chymosin. These moulds are fermented in a laboratory before being concentrated and purified to create microbial rennet. Microbial rennet is considered vegetarian-appropriate, but it has a reputation for occasionally causing bitterness, especially in aged cheeses. Additionally, microbial rennet can be tricky to use during the cheesemaking process and does not yield consistent results, making it less widely used.
While vegetarian rennet made from plants or microbial moulds provides an alternative to animal rennet, it is important to note that some people still have concerns about its use. Some believe that vegetarian rennet does not produce as good a depth of flavour as animal rennet. Additionally, there are concerns about the use of genetically modified organisms (GMOs) in some types of vegetarian rennet, particularly microbial rennet. In the United States, the FDA has passed GMO rennet as GRAS (Generally Regarded as Safe), and cheesemakers are not required to specify the type of rennet used on their labels.
