Casein is produced from pasteurized skimmed milk of approximately 3% total solids, in which the casein is precipitated by the action of heat and acid. About 80% of the protein in milk is casein. The acids used to precipitate casein can be mineral acid (hydrochloric or sulphuric) where the resulting product is generally termed as acid casein, or lactic acid producing lactic casein. Casein is separated and washed before drying.
Industrial Grade Casein have good binding properties and are used for the manufacture of paper coatings, match box, adhesives, paints, concrete, textile fabrics and cosmetics.
