Does sodium caseinate contain sodium?

The principal protein fraction of cows' milk. It accounts for about 80% of the protein content and is present in concentrations of 2.5--3.2%. Casein is a mixed complex of phosphoproteins existing in milk as colloidally micelles 50 to 600 nanometers in diameter. Caseins can be separated from the proteins of cows' milk by , high-speed , salting-out with appropriate concentrations of neutral salts, and (or other proteolytic enzymes), and as a coprecipitate with whey proteins. The first three methods yield preparations in essentially their native micellar state, but are http://www.answers.com/topic/impractical for commercial exploitation. Thus, commercial caseins are produced by methods more http://www.answers.com/topic/amenable to industrial practices.The early production of casein isolates was http://www.answers.com/topic/stimulate by their application in industrial products such as paper, http://www.answers.com/topic/glue, paint, and plastics. These applications have been replaced by petroleum-based polymers. Thus the emphasis has shifted to their utilization in food systems, where they add enhanced nutritional and functional characteristics. They are widely used in the formulation of comminuted meat products, coffee whitener, processed http://www.answers.com/topic/cereal products, http://www.answers.com/topic/bakery products, and cheese analogs. http://www.answers.com/topic/cheese-7.

SHORT ANSWER

Yes, that is why it has the word sodium in it's name.
