It is often listed as sodium caseinate, calcium caseinate, or milk
protein, whey, whey
protein concentrate, and many more. The biggest and baddest source of
casein (in my experience) is called Milk Protein Concentrate (MPC). This is basically the heroin of casein!! I read about it as my casein research linked to more and more articles.
You can find these casein proteins in food that is creamy. Scientists have isolated the specific proteins that give foods a creamy, dairy-like consistency.
