| Abstract:The effects of the crude enzyme of white-rot fungus treatment of the RMP pulp of the tobacco stem on the degradation rate of lignin, and the physical properties of the tobacco sheet were studied. The result indicated that the optimum conditions of treatment were as follows: enzyme dosage 15 IU/g, treatment time 3 h. Under above conditions, the degradation rate of lignin was 33.48%, the tensile strength and softness of the sheet was 9.13 N·m/g and 518 mN respectively. Moreover, through smoking test of the tobacco sheet treated with crude enzyme, the results indicated that the woody smell and stimulation reduced obviously, the quality was improved compared with the tobacco sheet without treatment. |
