我国不同生态区云烟87烟叶主要化学成分及感官风格差异

　　摘 要：為明确我国不同生态区云烟87烟叶主要化学成分及感官风格差异，采用描述性统计、方差分析和简单相关分析法对西南高原、黔桂山地、武陵秦巴和南岭丘陵4个生态区共288个云烟87烟叶样品进行了对比分析。结果表明，西南高原生态区上部叶“高糖低碱”、中下部叶“高糖中碱”，特征香韵为清甜香且与总糖相关系数（0.679）最大，余味好，刺激性和杂气小；黔桂山地生态区上部叶“高碱低钾”、中下部叶“高糖低氮”，特征香韵为正甜香且与总氮相关系数（0.503）最大，香气质和香气量高；武陵秦巴生态区上部叶“高碱中糖”、中下部叶“高糖高碱”，特征香韵为正甜香且与总糖相关系数（0.455）最大，香气质、香气量、浓度、劲头和余味均较小；南岭丘陵生态区上部叶“高碱高钾低糖”、中下部叶“高钾低糖”，特征香韵为焦甜香且与还原糖相关系数（0.529）最大，浓度高、劲头大。

　　Abstract： In order to study the differences of main chemical components and sensory styles of Yunyan 87 in different ecological regions of China，using simple descriptive statistics， variance analysis and correlation analysis， 288 Yunyan87 tobacco samples from four typical ecological regions of Southwest plateau， Guizhou mountain， Wulingqinba and Nanling hills were compared and analyzed. The results showed that in the Southwest plateau eco-zone the upper leaves were “high sugar and low nicotine”， middle and lower leaves were “high sugar and middle nicotine”. The characteristic flavor was sweet-smelling and the correlation coefficient with total sugar （0.679） was the largest. Irritation and gas mixture were small. In the ecological zone of Guizhou mountain， the upper leaves were “high nicotine and low potassium”， and middle and lower leaves were “low nitrogen and high sugar”. The characteristic flavor was positive and sweet and the correlation coefficient with total nitrogen （0.503） was the largest. The fragrance and aroma were high. In the Wulingqinba ecological zone， the upper leaves were “high nicotine and middle sugar”， and the middle and lower leaves were “high sugar and high nicotine”. The characteristic flavor of the fragrance was sweet and total nitrogen significant positive correlation coefficient （0.455） was the largest. Fragrance， aroma， concentration， strength and aftertaste were all small. In the Nanlin hills ecological zone， the upper leaves were “high potassium and nicotine and low sugar”， and middle and lower leaves were “high potassium and low sugar”. The characteristic flavor was caramelized and the correlation coefficient of reducing sugar （0.529） was the largest with high concentration and great strength.
