General description

Casein is a collective term given for a family of phosphoproteins generally found in the milk of mammals. It has wide applications in the paints, medical, plastics, and food industries. It is used to form self-healing-protective coatings. Edible casein films are used in food packaging applications as a good barrier to oxygen to protect products from oxidation. The Casein-based adhesive is used as a bottle-labeling adhesive for beer and soda bottles.

Application

Casein can be used as:
  • An adhesive in the preparation of magnesium composite applicable as a fire retardant coating used in the wood industry.
  • A superplasticizer in the self-leveling underlayment (SLU) formulation.

Biochem/physiol Actions

Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.
