Optimization of preparation process of Enteromorpha prolifera polysaccharide-iron and its structure characterization
摘要
Abstract
The optimal chelating conditions for Enteromorpha prolifera polysaccharide-iron were investigated by response surface methodology(RSM).It was characterized through fourier transform infrared(FTIR) spectroscopy and X-ray diffraction.Results showed that the optimal reaction conditions were temperature 54 ℃,chelating time 3.8 h,the mass ration of polysaccharide and ferric iron 3.9∶ 1,and pH7.5.The chelating rate could reach 19.6％.The FTIR indicated that the hydroxyl and carboxyl groups were chelated with Fe3+.The generation of E.prolifera polysaccharide-iron was further confirmed by X-ray diffraction to provide scientific basis for the high-value utilization of E.prolifera resource and the exploitation of a new iron supplement.关键词
