Sodium caseinate is the sodium salt of casein, a milk protein, appearing as a white to light yellow lyophilized powder with no distinct odor. It has variable molecular weight (around 20,000 g/mol subunits), high solubility in water (50 mg/mL), forming colloidal solutions with pH 6.5-7.5. Hygroscopic and stable, produced by acid precipitation of casein followed by sodium neutralization.
