Sodium caseinate
Sodium caseinate is casein made water soluble. Casein is precipitated from pasteurized skim milk with acid (acid casein), washed, then neutralized with sodium hydroxide and spray or roller dried. The result is a powder of about 90% protein that dissolves readily and is widely used as an emulsifier, whitener and protein source in coffee creamers, processed meats, bars, nutrition drinks and cheese analogs.
Suppliers sell different products under the same name. Specify the one you need.
Fine powder that dissolves quickly; the common grade for drinks and creamers.
Coarser powder with different flavor and solubility, used in some meat and bakery applications.
Grades sold by solution viscosity, chosen to fit emulsions, coatings or drinks.
Grades made to tighter micro and specification limits for medical nutrition and supplement use.
Compare each result with your own specification when the lot arrives.
Store sealed in a cool, dry place away from strong odors. Caseinate is fairly stable as a dry powder, but moisture causes caking and warm storage causes off-flavors over time. Shelf life is set by the supplier's specification, with a retest for aged stock.
Record protein, pH and viscosity for each lot, since viscosity differences change emulsion and drink texture. Note the drying method and rotate first-expired, first-out.

Suppliers are in alphabetical order and none pays to appear. Each claim is checked against the supplier’s own website on the date shown. Ask for the specification sheet and a recent COA before you order, and confirm details with the supplier.
Common forms include spray-dried, roller-dried, low-viscosity and high-viscosity grades and pharmaceutical or nutritional grade. Ask each supplier for the specification sheet of the exact grade they quote.
