Abstract:
The results from the comparison of iron source selection were showed that ferrous chloride was more suitable for the preparation of soybean peptide chelate iron. According to the study of the optimal process for soybean piptides chelate with different kinds of iron source by using the response surface method. The optimum condition was that mass ratio of small-peptide and ferrous salt was 4∶1, reaction pH was 5.0, reaction temperature was 40℃ and ion average chelating rate reached to 56.81%. In the pilot of workshop manufacturing, the soybean small-peptide chelated iron’s yield was 78.3%, chelating rate was 82.39%, the soybean protein content of small peptide chelate iron sample was 78.94%, iron content was 10.87%. The analysis test by infrared spectroscopic (IR) and Ultra Voilet Spectroscopy (UV), and the comparison for absorption peak between soybean small-peptides and soybean small-peptide chelated iron showed that there was obviously change in absorption in different IR wavelength infrared weak position, and the small soybean peptide chelate iron samples (Fe2+) also changed obviously in the UV wavelength displacement, so it was proved that small soybean peptide chelate iron(Fe2+) had been in complex compound. And its construction was forecast.
