Calcium caseinate

Calcium caseinate is a protein produced from casein in skim and sometimes 1% milk. At neutral or acid pH, casein is relatively insoluble in water, and is easily separated from other milk proteins, sugars and minerals. After their removal, the casein is solubilized at a high pH with calcium hydroxide; the solution is then dried (usually spray dried). Calcium caseinate contains about 17% glutamic acid.
