Rennet意思

Rennet is a complex of enzymes, specifically a proteolytic enzyme called chymosin, that is used in the production of cheese. It is derived from the stomachs of young ruminant animals, such as calves, and is used to coagulate milk, which is a crucial step in cheese making. The rennet works by causing the milk proteins, casein, to clot together, separating the milk into solid curds and liquid whey. This process is essential for the formation of cheese curds, which are then processed further to make various types of cheese. Rennet is available in both animal-derived and microbial forms, with the latter being a vegetarian alternative.
