- 摘要:
- 通过铁源筛选比较得知,氯化亚铁比较适合与大豆小肽进行螯合反应制备大豆小肽螯合铁,利用响应面法优化了大豆小肽螯合铁的制备工艺,优化结果为:小肽与亚铁盐质量比4∶1,反应pH5.0,反应温度40℃,得到离子螯合率平均值为56.81%,经中试车间生产试制得到大豆小肽螯合铁的得率是78.3%,螯合率为82.39%,检测大豆小肽螯合铁的主要成分中的蛋白含量为78.94%,铁的含量为10.87%。红外和紫外光谱分析检测结果显示:大豆小肽和大豆小肽螯合铁(Fe2+)红外吸收峰的强度在不同波长位置上有明显的变化,大豆小肽螯合铁(Fe2+)在紫外波长上发生了明显的位移且宽化,表明大豆小肽螯合铁(Fe2+)形成了络合物。同时对大豆小肽螯合铁的结构进行了预测。
- 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.
