摘要:

为明确烤房类型及排湿方式对烟叶烘烤质量的影响,本研究以常规外排湿热泵密集烤房(开式循环烤房)为对照,采用半叶法研究了内除湿热泵密集烤房(闭式循环烤房)对烤后烟叶主要化学成分、有机酸和中性致香成分含量(质量分数)的影响。结果表明,与开式循环烤房相比,闭式循环烤房烤后烟叶总糖含量显著(p<0.05)提高1.66百分点,还原糖含量显著提高2.30百分点,两糖比显著提高8.2%,糖碱比显著提高8.7%,淀粉含量显著降低3.05百分点,柠檬酸含量降幅为25.3%,2,4-庚二烯酸含量增幅为25.7%,γ-戊酮酸含量增幅为15.6%。变量投影重要性数值(VIP)显示,与开式循环烤房相比,闭式循环烤房烤后烟叶中有14种中性致香成分含量存在较大差异。综上,采用闭式循环烤房进行烘烤能显著提升烤后烟叶总糖、还原糖、2,4-庚二烯酸和γ-戊酮酸含量以及两糖比和糖碱比,可以显著提高部分中性致香成分含量。

Abstract:

In order to clarify the effect of curing barn types and moisture removal methods on the curing quality of tobacco leaves,the effects of the internal dehumidification heat pump bulk curing barn (closed-cycle curing barn)on the contents(mass fraction)of main chemical components,organic acids and neutral aroma components of flue-cured tobacco leaves were studied by half-leaf method,with the conventional moisture exhaust heat pump bulk curing barn (open-cycle curing barn) as control. The results showed that compared with the open-cycle curing barn,the total sugar content of flue-cured tobacco leaves in the closed-cycle curing barn was significantly(p<0.05)increased by 1.66 percentage points,the reducing sugar content was significantly increased by 2.30 percentage points,the ratio of reducing sugar to total sugar was significantly increased by 8.2%,the ratio of reducing sugar to total alkaloids was significantly increased by 8.7%,the starch content was decreased by 3.05 percentage points, the content of citric acid was decreased by 25.3%,the content of 2,4-heptadienoic acid was increased by 25.7%,and the content of γ-pentanoic acid was increased by 15.6%. The variable importance in projection (VIP) values showed that there were significant differences in the contents of 14 neutral aroma components in the flue-cured tobacco leaves of the closed-cycle curing barn compared with the open-cycle curing barn. The total sugar,reducing sugar,2,4-heptadienoic acid and γ-pentanoic acid content,ratio of reducing sugar to total sugar and the ratio of reducing sugar to total alkaloids of flue-cured tobacco leaves were significantly increased by using the closed-cycle curing barn,and the content of some neutral aroma components was significantly increased.
