摘　　要：用不同试剂比较其对丝素的溶解性，结果表明：可用ＣａＣｌ２热溶液代替ＬｉＢｒ作为丝素溶剂。溶解后的丝素溶液经透析去离子，再冷冻离心后即可在聚乙烯板上２５Ｃ成膜，丝素膜经甲醇、戊二醛β化处理后，性能稳定，可作为固相酶优良载体。Experin1ents of cocoon degumming were carriedout with different solvent,concentration of solvent,boiling time and variety of silkworm。The results showed that thebest degumming solvent are seponated olive-oil and scouring agent,the optimum concen-tration and boiling time of solvent were obtained.There were obvjous difference in:ericincontent in different varieties of silkworm.The difference is mainly deternmined by heredity ofsilkworrn.
