摘要
[目的]研究烘丝工序在来料水分波动较大的情况下不同水分调控模式烘后叶丝香味成分含量的差异性及变化趋势。[方法]分别针对来料水分偏高和水分偏低的情况采用对比论证法分析比较了容积比调控模式和筒壁温度调控模式下烘后烟丝的挥发性有机酸和关键致香物质含量的差异,并通过感官评吸对检测结果进行了验证。[结果]2种调控模式均能保证烘后物料含水率符合设计要求,采用筒内容积比的调控模式,烘后烟丝挥发性有机酸和关键致香物质的含量均高于采用筒壁温度的调控模式;针对挥发性有机酸,筒内容积比调控模式下叶丝中的异戊酸、2-甲基丁酸、苯甲酸和苯乙酸的含量明显高于采用筒壁温度调控模式;针对关键致香物质,筒内容积比调控模式下叶丝中的茄酮、巨豆三烯酮B、巨豆三烯酮D和金合欢基丙酮A的含量明显高于采用筒壁温度调控模式。[结论]研究可为制丝工艺选择合适的对致香成分和感官质量影响最小的控制模式提供依据。
[Objective]In order to study the difference and change trend of the content of the aroma components of silk leaves after drying under different moisture control modes under the condition of large moisture fluctuation in the incoming drying process.[Method]The contrastive analysis was used to analyze the difference of volatile organic acids and key aroma components of baked post-cured tobacco under the volume ratio control mode and tube wall temperature control mode,respectively,in view of the high water content and low moisture content.[Result]Results showed that the two control modes could ensure that the moisture content of the material after drying meets the design requirements.The control mode of the volume ratio of the cartridge was adopted.The contents of volatile organic acids and key aroma components of the cured tobacco were higher than those of the tube wall temperature;For volatile organic acids,the contents of isovaleric acid,2-methylbutyric acid,benzoic acid and phenyl acetic acid in leaf silk were obviously higher than that of tube wall temperature control mode.For the key aroma substances,the contents of silicone,megastigmatrienone B,megastigmatrienone D and acacia-based acetone A in leaf silk were obviously higher than those in control of tube wall temperature mode.[Conclusion]The study can provide a basis for the selection of suitable control mode for the selection of silk making technology which has the least influence on aroma components and sensory quality.
