Animal rennet is made from enzymes found in the lining of un-weaned mammal stomachs
Rennet is a key ingredient in cheesemaking, facilitating the formation of firm curds. It is a general term for enzymes that act on proteins in milk, triggering coagulation. The primary purpose of rennet is to coagulate milk, separating the solid components (casein protein, fat, and minerals) into curds and the liquid into whey (water, lactose, and whey protein).
Animal rennet, in particular, is made from enzymes found in the lining of un-weaned mammal stomachs. These enzymes slow down the digestion of milk, converting it from a liquid to a solid in the mammal's stomach. This process allows the young mammal to absorb nutrients from milk, which is their main source of food. As the mammal ages, these enzymes are no longer produced, which is why rennet is typically sourced from young animals, such as calves, lambs, or kids (baby goats).
Animal rennet has been used in cheesemaking for centuries and is considered traditional. It is derived from the stomachs of ruminants, which include cattle, goats, and sheep. These animals have unique digestive systems that produce the chymosin enzyme, which is essential for cheesemaking.
Animal rennet can be purchased in liquid, paste, or tablet form, and it has a long track record of success in cheesemaking. It is generally easier to work with compared to vegetable rennet, which is a newer product and technique.
The choice between animal and vegetable rennet depends on the type of cheese being made and whether vegetarian-friendly options are desired. While animal rennet is widely used in artisanal cheesemaking, most store-bought cheeses use vegetable rennet in their production.

Rennet is used to coagulate milk, separating the solid components from the liquid
Rennet is used in cheese-making to coagulate milk, separating the solid components from the liquid. It is the general name for enzymes that act on proteins in milk. Rennet contains about 90% chymosin, 10% pepsin, and other enzymes. It is traditionally sourced from the stomachs of ruminants, such as cattle, goats, and sheep, and has been used in cheesemaking for centuries. The enzymes in rennet slow down the digestion of liquid milk by turning it into a solid in the mammal's stomach, making it easier to absorb nutrients.
There are two main types of rennet: animal rennet and vegetable rennet. Animal rennet is derived from the stomachs of unweaned ruminants and has been traditionally used in cheesemaking. It is available in liquid, paste, or tablet form, and manufactured animal rennet is preferred by many cheesemakers due to its controlled potency and predictable results. Vegetable rennet, on the other hand, is a newer product and technique. It is suitable for vegetarians but can produce inconsistent results for beginners.
The choice between animal and vegetable rennet depends on the type of cheese being made and the maker's preferences. Animal rennet is generally easier to work with and has a long track record of success, while vegetable rennet offers the ability to create vegetarian-friendly cheese. The specific type of rennet can vary in source, potency, and form, all of which can affect the resulting cheese.
Rennet plays a crucial role in the coagulation process, triggering the transformation of liquid milk into a solid coagulum or curd. This separation of solids and liquids is essential for extending the shelf life of milk and creating cheese with a high yield. The coagulation occurs when proteins clump together, trapping fat and other solids. The addition of rennet helps extract the maximum amount of milk solids, ensuring a high yield of cheese.
In summary, rennet is a key ingredient in cheesemaking, used to coagulate milk and separate its solid and liquid components. The choice of rennet type and form depends on the specific cheese-making process and the desired outcome. Understanding the properties and effects of different types of rennet is essential for a smooth cheesemaking process and delicious results.

Rennet comes in liquid or dry forms, with liquid being the most common
Rennet is a key ingredient in cheesemaking, used to coagulate milk and form curds. It is derived from enzymes found in the stomachs of ruminants, such as calves, lambs, and kids. These enzymes help young mammals digest milk by curdling it in their stomachs. Rennet serves the same purpose in cheesemaking, curdling milk to separate the solid components (casein protein, fat, and minerals) from the liquid (whey, water, and whey protein).
There are two main types of rennet: animal rennet and vegetable rennet. Animal rennet is the traditional choice, used for centuries, while vegetable rennet is a newer alternative. Animal rennet is sourced from the stomachs of unweaned ruminants and contains the chymosin enzyme necessary for cheesemaking. Vegetable rennet, on the other hand, is suitable for vegetarians but can be challenging for beginners to use due to inconsistent results.
Rennet comes in various forms, including liquid, dry, paste, and tablet. The choice between liquid and dry rennet depends on personal preference and the type of cheese being made. Liquid rennet is the most common form, with most cheese recipes calling for liquid rennet at 200 IMCU per ml. It is often derived from animal sources and is easier to use, with more predictable results. Dry rennet, on the other hand, can be stored in the freezer and lasts longer, but it may be more challenging to work with due to varying strengths.
The specific type of rennet used in cheese can vary depending on the cheesemaker and the desired outcome. While animal rennet has a long history in cheesemaking, vegetable rennet provides a vegetarian-friendly alternative. The choice between liquid and dry forms of rennet further allows cheesemakers to customize their craft, with both options yielding delicious results.

Rennet is not always listed as an ingredient, but it is used in the cheese-making process
Rennet is a key ingredient in the cheese-making process, but it is not always listed as an ingredient on cheese packaging. This is because rennet is used in the process of transforming milk into cheese, rather than being present in the final product.
The purpose of rennet in cheesemaking is to trigger coagulation, or curdling, of the milk. This is achieved through enzymes that act on proteins in milk, causing them to clump together and separate into solid curds and liquid whey. Rennet contains about 90% chymosin, an enzyme originally derived from the stomachs of young ruminant animals like calves, lambs, and kids. The enzymes in rennet slow down the digestion of milk in these young animals, turning it into a solid for easier absorption of nutrients.
While rennet is not listed as an ingredient, it is understood that it is used in the cheese-making process. The absence of rennet as a listed ingredient may be due to the fact that it is considered a process aid rather than an ingredient. However, this lack of transparency can be problematic for consumers who wish to make informed choices about the cheese they consume, especially those who follow vegetarian diets.
The type of rennet used in cheesemaking can vary, with the two main sources being animal and vegetable rennet. Animal rennet is derived from the stomachs of ruminants, while vegetable rennet is a newer product and technique. The majority of store-bought cheeses use vegetable rennet, but many artisanal cheese makers prefer animal rennet due to its long track record of success and ease of use. The specific type of rennet chosen depends on the desired cheese variety, as different forms and potencies of rennet will yield different results.
