摘要

This present study investigated the ability of various soy protein hydrolysates(SPHs)in binding calcium.It was demonstrated that the amount of Ca-bound depended greatly on the SPHs obtained using different proteases,which included:neutrase, flavourzyme,protease M and pepsin.The maximum level of Ca-bound(66.9 mg/g)occurred when protease M was used to hydrolyze soy protein.Peptide fragments exhibiting high Ca-binding capacity had molecular weights of either 14.4 or 8-9 kDa.The level of Ca-bound increased linearly with the increment of carboxyl content in SPHs,and further deamidation on SPHs from protease M improved Ca-binding of the hydrolysate.
