| 中文摘要: |
| 为探究河南、 贵州、 云南、 福建 4 个典型生态区烤烟品种 K326 烟叶香型风格差异形成的物质基
础， 对其 B 2 F 烟叶的主要化学成分及中性致香物质含量进行分析。 结果表明： 不同香型风格烤烟主要化学成分
的差异具有一定的区域性， 清香型烟叶总糖、 还原糖、 钾含量较高， 而烟碱、 总氮、 氯含量较低； 浓香型烟叶烟
碱、 总氮、 氯、 钾含量较高， 总糖、 还原糖含量较低； 中间香型烟叶总糖低于清香型而高于浓香型， 还原糖低于
其他香型， 烟碱高于其他香型， 总氮高于清香型而低于浓香型， 钾、 氯含量介于浓香型和清香型之间。 不同香
型风格烤烟中性致香物质含量的差异也存在一定的区域性， 浓香型烟叶美拉德反应物、 西柏烷类反应物、 类胡
罗卜素降解产物含量较高， 而新植二烯含量相对较低； 清香型烟叶新植二烯含量较高； 中间香型烟叶美拉德反
应物、 芳香族氨基酸降解产物含量介于清香型和浓香型之间。 |
| 英文摘要: |
| To study the material foundation of aroma type styles of flue-cured tobacco derived from distinct ecological
regions， tobacco leaves from four typical ecological regions including Fujian， Yunnan， Henan， Guizhou， were served as
materials， and the main chemical components as well as neutral aroma components were analyzed. The results showed that there
were regional diversity of chemical components among different aroma type styles of flue-cured tobacco. Of which， for clean
aroma style flue-cured tobacco， the total sugar and reducing sugar level， and potassium content were high， whereas the total
nitrogen and chlorine content were low； for enriched aroma style flue-cured tobacco， the nicotine， total nitrogen， chlorine level and potassium content were high， however， the total sugar level and reducing sugar content were low； the total sugar level in intermediate aroma style flue-cured tobacco was higher than that in clean aroma style flue-cured tobacco while lower than that inenriched aroma style flue-cured tobacco. Among these three aroma type styles， the reduced sugar level in intermediate aroma style flue-cured tobacco was the lowest while the level of nicotine in this style was the highest， and the level of total nitrogen， chlorine，and potassium in this style were between the enriched aroma style and clean aroma style flue-cured tobacco. The regional diversity also existed in flavor aroma components among the different aroma type styles of flue-cured tobacco. The contents of maillard reaction products， cembrane degradation products and carotenoids degradation products in the enriched aroma style flue-cured tobacco leaves were high compared with other styles， but the level of neophytadiene was low. The neophytadiene content of clean aroma style flue-cured tobacco leaves was high， and the contents of maillard reaction products and aromatic amino acid degradation products of intermediate aroma style flue- cured tobacco were between the enriched aroma style and clean aroma style. |
