Etymology

The term 'casein' derives from the Latin word 'caseus', meaning 'cheese'. The discovery of casein as a distinct protein dates back to the 19th century when scientists began to isolate and study proteins from milk. It was first analyzed in the 1820s, and its importance as a nutrient was recognized shortly thereafter. Casein is not just vital in nutrition; it has significant applications in industrial processes. For example, casein can be used in adhesives and in the food industry as a food additive, emulsifier, and stabilizer. As a protein, it has unique properties that make it particularly useful in a variety of products, extending beyond nutrition into commerce and manufacturing.
