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.

Where is Sodium caseinate used?

• Food manufacturing and pharmaceuticals: emulsifier, stabilizer, and protein source
• Processed meats, coffee creamers, and dairy analogs: binds water and fat, improving texture and extending shelf life
• Infant formula and clinical nutrition: high-bioavailability protein source
• Bakery and confectionery: improves dough handling, moisture retention, and crumb structure
• Pharmaceutical tablet coatings and nutritional supplements: binder and controlled-release matrix component
• It features favorable amino acid profiles suited to specialized dietary formulations.

Good to know: 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.

Commercial specifications

• High-protein content variants, typically 85 to 90 percent protein on a dry basis
