摘要[目的]明确仓库气氛调控剂对贵州省特定温湿度条件下片烟醇化效果的影响。[方法]选取2011年度黔西南地区的B2X、B2C、B3B和黔南地区B2X、C3F、B2B 6个等级的片烟，进行气调养护贮存2年，以常规密封贮存为对照进行比较；再将醇化2年后的片烟按前处理继续贮存1年，进行延展性试验，通过测定样品的内在理化指标和感官质量评价来分析其影响程度。[结果]6个等级片烟经密封降氧贮存后，片烟颜色转深得到一定程度上的抑制；烟叶评吸综合得分与对照相比基本一致，随时间增加综合得分均有所上升；理化指标测定结果显示，密封降氧处理对烟叶的影响与正常贮存效果基本相同，总糖、还原糖和总植物碱含量均有所下降，糖碱比更趋向于最适。[结论]气调剂的使用对片烟的醇化进程抑制影响较小。

Abstract[Objective] In order to identify the impact of airregulating agent on aging tobacco quality in Guizhou specific temperature and humidity conditions. [Method] The six grades of tobacco， B2X， B2C， B3B of southwest， and B2X， C3F， B2B of southern Guizhou Province in 2011 were selected to sealed deoxygenation aging for two years. After the pretreatment， the tobacco were continue to be stored for one year as extensibility experiment， and the normal aging group as controls. For analyzing the degree of influence， the physical and chemical analysis and artificial smoking value of the measured tobacco were tested. [Result] The results showed that composite score of artificial smoking value in six grades of tobacco with airregulating agent aging are consistent compared with the control group， and the tobacco color from overdarkening during aging were inhibited under said condition to a certain extent. The overall score is increasing with time. Physical and chemical analysis showed that the effect of sealed deoxygenation aging to tobacco as same as the control group. The total sugar， reducing sugar and total alkali of tobacco has declined， and the sugar/nicotine ratio tends to be more optimal. [Conclusion]There are no inhibition effect on putting airregulating agent to tobacco aging process.

煙叶醇化的实质是将烟叶中不利的品质成分在特定的环境条件下，经过连续的生物化学反应最终转换成有利的品质成分[1]。在这一过程中烟叶会受到物理因素（环境温度、相对湿度、空气含氧量）和生物因素（包括微生物、酶等）及烟叶醇化工艺（烟叶含水率、烟叶包装差异）等的影响，其中物理因素在醇化过程中起着极其重要的作用[2-5]。目前，为提高烟叶醇化品质，多釆用物理处理、添加活性物质、发酵工艺改造、加料醇化以及胶囊方法等各种技术来改善烟叶醇化条件[6-7]。……
