大豆球蛋白酶解物的抗氧化性及汞离子结合特性的研究
The antioxidant activities and Hg-binding properties of soy glycinin hydrolysates
摘要
Abstract
The antioxidant activities and Hg-binding properties of reduced soy glycinin hydrolysates were studies comparing with that of non-reduced soy glycinin hydrolysates.Results indicated that the content of sulfhydryl group was 120 μmol/g,which was 100-fold of that of non-reduced soy glycinin hydrolysates.The molecular weight of reduced hydrolysates was smaller than non-reduced hydrolysates and their hydrophobic distributions were similar.The IC50 of Super oxygen anion free radical,hydroxyl free radicals and DPPH radical of reduced hydrolysates were 18 mg/mL,20 mg/mL and 0.7 mg/mL,respectively.The Fe3+ reducing power was 0.557 when the concentration of peptide was 2 mg/mL.The Hg-bingding mass was 8 mg/g.The antioxidant activities and Hg-binding capacities of reduced soy glycinin hydrolysates were higher than those of non-reduced hydrolysates.It was indicated that reduced soy glycinin hydrolysates possessed potent potential in mercury detoxification.关键词
