Objective To research the key technology of chelation reaction of soybean protein hydrolysates chelating calcium, and the improvement of chelating rate with the pulses electric field(PEF) as an assistant method. Methods Eggshell and soybean protein hydrolysates were used as raw material, and chelating rate was used as testing indexes. To optimize chelation rate of the soluble complexes formed during calcium binding by soybean protein hydrolysates, 4 important parameters (pH value, temperature, time and mass ratio) were examined in this experiment. Results According to one-factor-at-a-time and response surface experiment, the regression model was:Y=94.96-0.074X1+0.30X2-0.14X3-0.45X4+0.012X1X2+0.060X1X3+0.37X1X4-0.32X2X3+0.64X2X4-0.085X3X4-0.42X12-0.93X22-0.34X32-0.15X42, the optimum preparation conditions of soybean protein hydrolyzates product chelating with calcium were obtained as follows: soybean protein hydrolyzates/calcium mass ratio of 1:1.75, pH 8.0, electric field intensity 15 kV/cm, and frequency 1200 Hz. Under these conditions, the chelation rate achieved to 95.38%±0.18%. Conclusion A scientific basis was provided for soluble complexes formed during calcium binding by soybean protein hydrolysates.
