Abstract: Optimum conditions of a new mineral protein salt made by hydrolysis of soy protein isolate, whose molecular weightwas under 10 kDa chelated with Zinc was studied. The results showed that the best conditions for this chelate was: the concentrationof soybean peptide was 4%,the mass ratio of soybean peptide to Zinc 2.25:1 ,temperature 6℃,pH 5.0,and the chelate time40min.

Key words: soybean peptide, chelation, Zinc
