| 摘 要： | 为深入了解云南烤烟主要化学成分含量及其分布特征,以云南主产烟区烤烟样本为材料,检测分析了327个C3F等级烟叶的30种成分指标。结果表明,云南烟叶中的氯、两糖差、钾/氯值、淀粉、糖/碱值和柠檬酸变异系数较大,受产地生态环境和种植技术的影响较大。烟叶中的糖含量、糖碱比和钾氯比较高,氯含量较低;总糖、还原糖和氯含量分别为30.96%、26.81%和0.24%;糖碱比和钾氯比分别为13.97和11.07。研究得出了云南烤烟中30种主要化学成分指标的频率分布特点,这对各卷烟企业了解云南烟叶化学成分特点和烟叶资源配置具有重要参考价值。

| Abstract: | To find out characteristics of main chemical components and its distribute frequency of flue-cured tobacco in Yunnan province,327 samples graded C3F of flue-cured tobacco from main tobacco planting areas in Yunnan province were analyzed.The results showed that Yunnan tobacco leaf effected much by producing areas and ecological condition,chlorine,TS(total sugar)-RS(reducing sugar),potassium-chlorine ratio,starch,sugar-nicotine ratio and citric acid had higher CVs.Yunnan tobacco leaf characterized high sugar,sugar-nicotine ratio and potassium-chlorine ratio,and low chlorine,its contents of TS,RS,and chlorine were 30.96%,26.81% and 0.24% respectively,the values of sugar-nicotine ratio and potassium-chlorine ratio were 13.97 and 11.07 respectively.The results were important basis for cigarette factories to understand the character of tobacco in Yunnan and scheme tobacco resource. |
