摘要:
对我国8个典型浓香型烟叶产区(安徽皖南、广东南雄、河南许昌、河南漯河、河南南阳、湖南浏阳、湖南郴州、山东潍坊)X2F、C3F和B2F等级的烟叶,共计72个烤烟样品主要化学成分及其派生值进行分析和评价。结果表明,不同地区烟叶化学成分的差异主要表现在总糖、还原糖、钾、糖碱比和钾氯比几个方面,安徽皖南、广东南雄、湖南郴州和湖南浏阳4个南方浓香型烟区总糖、还原糖和钾含量较高,糖碱比与钾氯比较大,河南许昌、河南漯河、河南南阳和山东潍坊4个黄淮烟区与之相反;安徽皖南、广东南雄、湖南郴州、湖南浏阳产区钾氯比适宜,河南许昌、河南漯河、河南南阳、山东潍坊产区糖碱比较适宜。

Abstract:
To improve the quality of tobacco leaves,72 tobacco leave samples with three grades were collected from 8 aromatic flue-cured tobacco production areas(Anhui Wannan,Guangdong Nanxiong,Henan Xuchang,Henan Luohe,Henan Nanyang,Hunan Liuyang,Hunan Chenzhou and Shandong Weifang) and were analyzed for evaluating their main chemical components.The results showed that the changes of chemical components observed mainly in the aspects of total sugar,reducing sugar,potassium,chlorine,total sugar/nicotine and K/ Cl.The content of total sugar,reducing sugar,potassium and the ratio of sugar/nicotine,K/Cl were higher in the tobacco leave samples from southern production areas(Anhui Wannan,Guangdong Nanxiong,Hunan Liuyang and Hunan Chenzhou) than from the production areas of Yellow River and Huai He River(Henan Xuchang,Henan Luohe,Henan Nanyang,Shandong Weifang).The ratio of K/Cl in samples from four former areas was favorable and the total sugar/nicotine in samples from four latter was appropriate.
