Calcium caseinate is a spray-dried milk protein powder whose surface has been treated with food-grade glyceryl monooleate. It disperses readily in water to form a stable colloidal suspension, and exhibits a mild flavor with excellent flavor stability. As a natural ionic calcium source, its calcium ions form stable chelate structures with the phosphate groups on serine residues in casein molecules, endowing it with superior bioavailability. Once ingested, it can be directly and efficiently absorbed by the intestinal tract, enabling effective calcium supplementation without the need for additional vitamin D. At the same time, this ingredient possesses multiple food functional properties including thickening, viscosity building, emulsification, and foaming. In food systems, it not only fortifies nutrition but also improves texture, achieving an integrated "calcium supplementation + texture modulation" effect, making it particularly suitable for formulations with flavor sensitivity.
Application Scope
① Health care and pharmaceutical fields: As a high-quality calcium source and protein supplement, it is widely used in calcium tablets, oral liquids, protein powders, and other nutritional health products as well as pharmaceutical formulations.
② Food processing industry: Leveraging its outstanding thickening, emulsifying, and foaming capabilities, it can be flexibly added to nutritionally fortified beverages, processed cheese, fermented yogurt, baked bread, and other products, enhancing calcium content while optimizing mouthfeel and stability.
