凉山烤烟还原糖含量状况及其与感官质量的关系

目的]研究凉山烤烟还原糖含量状况及与其与感官质量的关系.方法]以凉山州主产烟区烤烟样品为材料,运用多重比较和灰色关联度分析方法,分析了凉山10个烟区177份烟叶样品的测试数据.结果]凉山烟区烟叶还原糖平均含量为29.76％,烟叶还原糖含量多分布在22.50％～ 35.00％;还原糖平均含量在部位间的分布特征表现为上部叶＞中部叶＞下部叶.高、中、低还原糖含量组别间的香气量、余味、杂气、回甜感、成团性得分和评吸总分的差异均达到了1％极显著水平,不同组别间的香气质和细腻度得分的差异达到了5％显著水平;感官质量各指标与还原糖的关联顺序为余味＞杂气＞回甜感＞干燥感＞刺激性＞香气质＞细腻度＞香气量＞成团性.结论]该研究为凉山地区烟叶质量的提高、烟叶香吃味的改善以及烤烟原料的合理利用提供参考依据.

Study on the Reducing Sugar Content and its Relationship with Smoking Quality of Flue-cured Tobacco in Liangshan

Objective] The research aimed to study the reducing sugar content and its relationship with smoking quality of flue-cured tobacco in Liangshan.Method] Take that the flue-cured tobacco samples in the main producing area of Liangshan Prefecture as material,the 177 tobacco samples that taken from 10 tobacco-growing areas of Sichuan Liangshan weer analyzed by the multiple comparisons and grey correlation analysis method.Result] The average reducing sugar content of flue-curd tobacco was 29.76％ in Liangshan.And the reducing sugar content of most samples was between 22.50％-22.50％.The distribution of reducing sugar content in different parts was upper leaves ＞ middle leaves ＞ lower leaves.Dissimilitude of aroma amount,aftertaste,mixed gas,aftertaste sweet feeling,conglobation and total score of smoking quality between high,medium and low reducing sugar content were reached 1％ significant level.Dissimilitude of aroma quality and exquisite degrees between different groups were reached 5％ significant level.Correlations between different indicators of smoking quality and reducing sugar were：aftertaste ＞ mixed gas ＞ aftertaste sweet feeling ＞ dry feeling ＞ irritating＞ aroma quality ＞ exquisite degrees ＞ aroma amount ＞ conglobation.Conclusion] The study provides the reference for improving the quality of tobacco leaves,improving the aroma and taste of tobacco and the rational use of raw flue-cured tobacco in Liangshan region.
