Key Properties
Rennin, also known as chymosin, is a milk-clotting enzyme derived from the fourth stomach of calves. It plays a crucial role in the cheese-making process by coagulating milk, which is essential for curd formation. This enzyme is particularly valued in the dairy industry for its ability to produce high-quality cheese with desirable textures and flavors. With a molecular weight of approximately 31,000 g/mol, rennin is classified as an enzyme protein and is widely used in both commercial cheese production and dairy science research.
Also known as Chymosin.

- Substance
Rennin appears as an off-white to tan powder or liquid, depending on its formulation. It is soluble in water, allowing for easy incorporation into milk during the cheese-making process. The enzyme exhibits stability under a range of pH conditions, typically functioning optimally at a pH of around 6.0 to 7.0. The melting point is not applicable as it is a protein; however, it is generally stable at refrigeration temperatures. The enzyme's activity can be affected by temperature, with optimal activity usually observed between 30°C and 40°C.

Rennin is primarily used in the cheese-making industry, where it is essential for coagulating milk to form curds. It is utilized in the production of various cheese types, including cheddar, mozzarella, and parmesan. Beyond cheese production, rennin is also employed in dairy science research to study milk coagulation and enzyme activity. Additionally, it finds applications in the production of certain dairy products, such as yogurt and casein, and is sometimes used in the pharmaceutical industry for its enzymatic properties.
