| 摘 要： | 研究脱胶条件对蚕丝木瓜蛋白酶脱胶效果的影响.由单因子实验选出合适的酶质量浓度、温度、时间、pH值范围,用正交实验优化脱胶条件.结果表明.木瓜蛋白酶能有效地脱除丝胶:脱胶率和丝的强力损失率,随着酶质量浓度增加、pH值及温度的升高和脱胶时间的延长而上升;正交实验证实酶质量浓度是影响脱胶率的丰要因子,酶脱胶时间是强力损失的主要影响因素;综合考虑脱胶率和强力损失率,确定生丝木瓜蛋白酶脱胶的2个较好工艺条件为:一是酶质量浓度3 g/L、pH6、温度85℃、时间60 min;二是酶质量浓度3 g/L、pH8、温度65℃、时间90 min.

| Abstract: | This study investigated whether the degumming conditions had effect on mulberry silk degumming with papain.It used single-factor experiment to pick up the proper enzyme quality-concentration,temperature,time,pH value range,and then obtained optimized degumming conditions by orthogonal experiment.The results indicated that papain can effectively remove sericin.The results of the single-factor experiments showed the degumming loss rates and silk degumming strength loss rate are increasing with the enzyme conc... |
