The enzymology of milk and other products is of enormous significance for the production and quality of almost every dairy product. Milk itself is a complex biological fluid that contains a wide range of enzymes with diverse activities, some of which have identifiable functions while others are present as an accidental consequence of the mechanism of milk secretion. Over time milk enzymology has become an incredibly essential component of milk and other dairy product production, and with advancing technology and processing techniques, its importance is at its peak. 
Dairy Enzymology presents an expansive overview of the enzymology of milk and other dairy products, focusing on the use of indigenous and endogenous enzymes in milk and exogenous enzymes in cheese processing. A full section is dedicated to the enzymology of bovine milk, focusing on the main families of indigenous enzymes as well as their potential significance in the mammary gland plus the technological significance for the properties of dairy products. Implications for the manufacture and ripening of cheese plus the use of enzymes such as alkaline phosphatase for measuring heat treatment in milk are explored in full, and the role of milk protease plasmin and other indigenous enzymes in the age-gelation is focused on. Further sections focus on enzymes found in raw milk and enzymes deliberately added for manufacture or modification of properties and the manufacture of food ingredients from dairy-derived ingredients. The key bacterial families are discussed in depth as well as their known contributions to the quality of dairy products. 

With its comprehensive scope and fully up-to-date coverage of dairy product enzymology, this text is a singular source for researchers looking to understand this essential dairy processing aspect.
