研究了猪血多肽与铁盐进行螯合反应的条件,并测定了猪血多肽铁螯合盐的成分。试验表明:氯化亚铁适合作为多肽与铁进行螯合反应的铁源,猪血多肽铁螯合盐的最佳制备工艺条件为,pH值5、多肽与亚铁盐质量比4∶1、多肽溶液浓度3.0%,猪血多肽铁螯合盐的主要成分是多肽和铁,其质量分数分别为70.02%和12.23%。

The chelating reaction condition was studied between pig blood polypeptide and molysite.The ingredients of pig blood polypeptide-iron were also determined.The results showed that ferric chloride was suitable as iron source in chelating with pig blood polypeptide;the best condition was pH 5,the ratio of polypeptide and iron was 4∶1,solution concentration of polypeptide was 3.0%.The main contents of pig blood polypeptide-iron were polypeptide and iron with mass percents 70.02% and 12.23%,respectively.
