Acid Casein or Casein (acid) is the principal, non-heat-coagulable milk protein (a phosphoprotein) obtained by acid precipitation of skim milk, often at its isoelectric point (pH 4.6). Acid Casein's chemical character is defined by a complex polymeric structure rich in essential amino acids, making it a complete protein. Versatility stems from its molecular size: as the whole protein, it functions as a strong binder, emulsifier, and nutritional fortifier in food and industrial coatings. When subjected to acid hydrolysis (becoming Casein Hydrolysate, CAS 65072-00-6), it transforms into a highly soluble mixture of free amino acids and short peptides, which is utilised extensively in biochemistry and cell culture media as a high-purity nitrogen source. Known by Acid Precipitated Casein by Acid Casein supplier and Lactein by Acid Casein manufacturer. We are globally established nutraceutical suppliers, from sourcing to manufacturing scaling, through comprehensive regulatory documentation (CoA), manufacturing compliances, traceability, and consistent worldwide supply capabilities, ensuring reliable lead times and quality assurance across all grades.
