Casein is a protein which is commonly found in mammalian milk, which is about eighty percent of protein in cow milk and around twenty to forty five percent in human milk. In milk, these proteins are found as suspensions in the form of micelles. As a source of food, casein supplies amino acids, carbohydrates and two important minerals calcium and phosphorous.
Casein has a wide variety of applications. Casein paint is a water-soluble, fast-drying medium which is used by artists. Until the advent of acrylic paint, it was widely used by commercial painters as the material of choice. Glues which are based on casein, water, sodium hydroxide and hydrated lime were earlier popular for woodwork and aircraft making. Cheese is prepared by the coagulation of casein.
