Pepsin and the Vegetarian Diet
Pepsin is a proteolytic enzyme that is crucial for the digestion of proteins in the stomach. It is typically extracted from the stomach lining of pigs and used in various food processing applications, particularly in the production of cheese and other dairy products where it acts to break down proteins to aid in curd formation. It can also be used in the production of certain meat and fish products to enhance texture and flavor.
