Acid Casein is a food-grade high-protein milk derivative produced by acid precipitation of skim milk at isoelectric pH (4.6).We supply bulk Acid Casein sourced from leading China manufacturers, available in powder form to meet global food industry demand. Our Acid Casein is widely used in caseinate production, beverages, sports nutrition products, confectionery protein enrichment and technical applications.
Acid Casein is manufactured by acidifying pasteurised skim milk with hydrochloric or lactic acid to pH 4.6, precipitating casein, followed by washing, dewatering and drying.
It is an insoluble, water-white to cream coloured powder used as the raw material for sodium, calcium and potassium caseinates, and directly in protein-fortified foods, beverages and industrial adhesives.
