Abstract
Non-phosphorylated peptides and phosphopeptides useful as alimentary products or medicaments are produced by proteolytic enzyme hydrolysis of a casein-based material. Membrane ultrafiltration is used to separate phosphopeptides which are retained by the membrane in a retentate from the non-phosphorylated peptides which pass through the membrane in an ultrafiltrate. The phosphopeptides in the retentate are disaggregated and are subjected to further membrane ultrafiltration where the phosphopeptides pass through the membrane and are separated from the enzyme. The non-phosphorylated peptides have nutritive value and can be used to form compositions for providing nutrition. The phosphopeptides form salts, which have dietetic uses, with macroelements such as calcium and/or magnesium and/or oligoelements such as iron and zinc.
