摘　　要：研究比较了丝素的氯乙酸热改性、氯乙酸微波催化改性和乙二胺四乙酸固相微波催化改性等几种接枝改性方法 ,结果表明 :前 2种方法丝素接枝率很低 ,最高接枝率分别仅为 7.2 %和 4 .5 % ;而采用乙二胺四乙酸固相微波催化方法丝素接枝率最高可达到 6 3.8% ,大大改良了丝素的分子结构和性能。Three denaturation methods for sericin were compared, i.e. chloroacetic heat denaturation, chloroacetic microwave catalyzed denaturation and EDTA solid phase microwave catalyzed denaturation. The ingraft rate of the first two methods was low, being 7.2% and 4.5%, respectively, while that of the third method was as high as 63.8%. Thus EDTA solid phase microwave catalyzed denaturation substantially improved the molecular structure and quality of sericin.
