生物酶脱胶工艺在制备桑皮纤维中的应用

用生物酶(KDN-T01F)对桑皮进行脱胶,分析脱胶过程中的各个影响因素,以残胶率作为衡量脱胶效果的指标.采用单因子分析法找出脱胶过程中各因素的参数范围,在此基础上,通过正交试验制定生物酶脱胶的最佳工艺条件,即在温度为53℃、生物脱胶酶溶液质量浓度为14 g/L、溶液的pH值为9、脱胶时间为12 h和浴比为1:30的条...

Biological enzyme applied to extraction of mulberry fiber

Bio-degumming of mulberry fiber was performed with bioenzyme KDN-T01F, and the factors affecting degumming were investigated, using the amount of residual gum as the index of the result of degumming. Single-factor analysis was adopted to find out the parameters range during degumming, and then orthogonal experiment was used to determine the optimal parameters for bio-degumming, that is, the temperature is 53℃, the concentration of bioenzyme solution is 14g/L, pH =9, liquor ratio is 1:30 and treating time is 12h. Under these conditions, the amount of residual gum reduced from 68.04% to 30.36%. After bio-degumming followed by chemical degumming，the amount of residual gum is as low as 3.88%. This indicates that bioenzyme - chemical degumming method is good for extraction of mulberry fiber.
