酶法对烟梗丝降解效果的研究

目的]寻求不改变现有制梗丝工艺条件的酶处理技术,以提高烟梗丝的内在质量。方法]基于现有制梗丝技术和洗梗工艺条件,通过加酶洗梗处理,对烟梗的主要组成成分进行适量降解,并通过单因子试验和正交试验,比较果胶酶MG（0.32 U/g）、木质素酶MM（500 U/g）和纤维素酶MQ（1 000 U/g）降解烟梗丝的效果,确定其最佳用量。结果]方差分析表明,果胶酶以及纤维素酶对烟梗的降解效果非常显著。烟梗水解试验的最优工艺条件为：MG浓度为0.10%,MQ浓度为0.10%。在该浓度水平下,烟梗降解率可达32.50%～37.18%。结论]利用酶技术可有效降解烟梗丝中的纤维素和果胶质,可根据贮梗时间对水解产物的含量进行有效调控,从而有助于促进中间香味质的转化,提高烟梗丝的内在质量。

Research on Degradation Effect of Tobacco Stem-silk by Enzyme Treatment

Objective] The study aimed to seek for enzyme processing technology without changing the existing process conditions of making the stem-silk,so as to improve the immanent quality of tobacco stem-silk.Method] Based on the existing technology of making stem-silk and the existing process conditions of washing stem,through the treatment of adding the 3 enzymes to wash the stems,the main composition of tobacco stem were moderate to be degraded,and through the single factor test and the orthogonal test,the effe...
