  • Soybean phosphopeptide calcium and method for producing thereof
    Patent number: 7048955
    Abstract: The present invention relates to soybean phosphopeptide calcium and method for producing thereof, wherein the soybean phosphopeptide calcium is produced by calcium-binding reaction of soybean phosphopeptides which are obtained from hydrolysis with hydrolase followed by chemical phosphorlyation of soybean protein using polyphosphate salts or inversely from the procedure of chemical phosphorlyation before hydrolysis with hydrolases. The optimum conditions for the sequential reactions of enzymatic hydrolysis, phosphorylation and calcium binding were established. The soybean phosphopeptide calcium has a high solubility in water and an efficient absorption rate of calcium in a living body.
