以胡萝卜渣中的纤维为原材料,研究纤维素酶和半纤维酶对胡萝卜纤维的长度、宽度以及还原糖浓度和聚合度的影响,并对在胡萝卜纤维改性过程中纤维素酶和半纤维酶协同作用的机理进行探讨。结果表明,纤维素酶和半纤维素酶复合使用比单一酶对胡萝卜纤维改性效果明显。在两者的协同作用下,可以改善纤维表面的细纤维化,提高纤维的酶解产率,降低纤维的聚合度。

This paper studied the influence of cellulase and hemicellulase on the length,width,sugar content and polymerization degree of carrot pomace fiber.The mechanism of synergy of cellulase and hemicellulase modified carrot fiber was analyzed.The result indicated that the complex application of cellulase and hemicellulase was more obvious effect than the single enzyme.And the synergism of cellulase and hemicellulase could improve the thin fibrosis of the fiber surface,enhance the production rate of enzymolysis fiber,and reduce the polymerization degree of the fiber.
