贵州有机生态烟叶主要化学成分与感官质量的相关分析研究

为探索贵州有机生态烟叶主要化学成分和感官质量的关系，试验对贵州省内7个产区（贵定、兴义、天柱、威宁、务川、道真、遵义）42个样品的主要化学成分和感官质量进行分析。结果表明：各产区样品化学成分较协调，两糖比基本在适宜范围之内，烟碱含量地区间差异不大，多地区上部叶烟碱和氯含量降低。感官评吸质量较好，主要表现为劲头下降，特别是遵义、道真和务川。威宁的清香较显著，飘逸感较好。所测样品香气质、香气量、燃烧性、灰色、评吸总分与糖碱比、氮碱比均呈极显著负相关关系；刺激性与总糖、还原糖含量呈显著正相关关系。

Study on relationship between main chemical components of eco-organic tobacco from Guizhou province and sensory quality

Main chemical components and sensory quality of 42 eco-organic tobacco samples from 6 grades and 7 production sites in Guizhou Province (Guiding, Xingyi, Tianzhu, Weining, Wuchuan, Daozhen, Zunyi) were analyzed to study relationship between main chemical components and sensory quality. The results showed that chemical components of samples of each production site were more coordination. Two sugar ratio substantially was in the appropriate range. The difference of the nicotine content between different areas was little and the nicotine and chlorine content of the upper part of leaf in the multi-region was lower. The sensory quality and tobacco comprehensive quality were better. The strength was declined, especially Zunyi, Daozhen and Wuchuan and the fragrance of the tobacco in Weining was more significant. The aroma quality, aroma quantity, flammability, gray, and smoking total score of the measured samples were highly significant negative correlation with the ratio of sugar to nicotine and the ratio of nitrogen to nicotine. The biting taste was a significant positive correlation with total sugar and reducing sugar content.
