METHODS OF PHOSVITIN EXTRACTION AND PHOSPHOPEPTIDE PREPARATION FROM EGG YOLK

The invention is directed to methods for extracting phosvitin from egg yolk involving contacting the egg yolk or egg yolk protein granules with a solution having a salt concentration of about 10% to form a mixture; optionally, heating the mixture; adjusting the pH of the mixture to separate phosvitin from other proteins; recovering the phosvitin. The phosvitin extract may be dephosphorylated and hydrolyzed to produce phosvitin phosphopeptides.
