Transparent acid drink containing acid-soluble casein phosphopeptide

摘要

A transparent storage stable acidic beverage or other alimentary product containing casein phosphopeptide is obtained by reacting casein with trypsin, precipitating insoluble components at acid pH, adding a divalent cation such as calcium to the reaction medium, recovering the reaction product, and adding the casein phosphopeptide to a mixture to produce a beverage or product having beneficial solubilizing effects on calcium.
