  • Non-phosphorylated peptides from casein-based material
    Patent number: 4740462
    Abstract: Nonphosphorylated peptides and phosphopeptides useful as alimentary products or medicaments are produced by proteolytic enzyme hydrolysis of a casein-based material. Ultrafiltration is used to separate phosphopeptides and nonphosphorylated peptides after hydrolysis. A bivalent cation is added to form aggregates of the phosphopeptides, and the aggregated phosphopeptides are separated from the nonphosphorylated peptides by ultrafiltration. The phosphopeptides form salts, which have dietefic uses, with macroelements such as calcium and/or magnesium and/or oligoelements such as iron and zinc.
