Sodium caseinate

Sodium caseinate (CAS 9005-46-3), also known as casein sodium salt, is a milk-derived protein produced by neutralizing acid casein with sodium hydroxide. It functions as an emulsifier, stabilizer, and protein source across food manufacturing and pharmaceutical applications.

In processed meats, coffee creamers, and dairy analogs, it binds water and fat simultaneously, improving texture and extending shelf life. Infant formula and clinical nutrition products rely on it as a high-bioavailability protein source.

This ingredient features favorable amino acid profiles suited to specialized dietary formulations. Bakery and confectionery manufacturers use it to improve dough handling, moisture retention, and crumb structure in finished products.

In pharmaceutical tablet coatings and nutritional supplements, it acts as a binder and controlled-release matrix component. Sodium caseinate is supplied as a spray-dried or roller-dried white to cream powder for various uses.

Spray-dried grades are preferred where solubility and dispersibility are critical. Standard commercial grades include food-grade and FCC-compliant specifications, with edible and feed grades also available depending on end-use requirements.

High-protein content variants, typically 85 to 90 percent protein on a dry basis, are commonly offered for nutritional and functional food applications. This ensures high quality and performance across diverse industrial sectors.
