  摘 要:為明確我國不同生態(tài)區(qū)云煙87煙葉主要化學(xué)成分及感官風(fēng)格差異,采用描述性統(tǒng)計、方差分析和簡單相關(guān)分析法對西南高原、黔桂山地、武陵秦巴和南嶺丘陵4個生態(tài)區(qū)共288個云煙87煙葉樣品進行了對比分析。結(jié)果表明,西南高原生態(tài)區(qū)上部葉“高糖低堿”、中下部葉“高糖中堿”,特征香韻為清甜香且與總糖相關(guān)系數(shù)(0.679)最大,余味好,刺激性和雜氣。磺鹕降厣鷳B(tài)區(qū)上部葉“高堿低鉀”、中下部葉“高糖低氮”,特征香韻為正甜香且與總氮相關(guān)系數(shù)(0.503)最大,香氣質(zhì)和香氣量高;武陵秦巴生態(tài)區(qū)上部葉“高堿中糖”、中下部葉“高糖高堿”,特征香韻為正甜香且與總糖相關(guān)系數(shù)(0.455)最大,香氣質(zhì)、香氣量、濃度、勁頭和余味均較。荒蠋X丘陵生態(tài)區(qū)上部葉“高堿高鉀低糖”、中下部葉“高鉀低糖”,特征香韻為焦甜香且與還原糖相關(guān)系數(shù)(0.529)最大,濃度高、勁頭大。

  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 “l(fā)ow 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.
