不同产地香料烟内在化学成分及致香物质分析

收集了国内外6个产地不同等级的香料烟样品，对其内在化学成分、必需营养元素和挥发性致香物质等进行了分析。结果表明，不同产地香料烟中总糖含量为11．71％～32．18％，烟碱含量为0．59％～1．72％，淀粉含量为4．98％～10．65％，石油醚提取物为4．85％～6．50％；香料烟中单糖含量远高于双糖，在双糖中蔗糖含量较高，调制后的烟叶中几乎不含麦芽糖；几种必需营养元素在不同产地香料烟中的含量变化范围较大，这些元素与香料烟中糖和烟碱含量之间表现出不同的相关性；不同产地香料烟内含有的致香物质成分大体上一致，但在含量上却有明显的差异。

Analysis on chemical components and flavor substance in oriental tobacco of different producing areas

Different grades of oriental tobacco samples from6producing areas at home and abroad were collected and analyzed for chemical components,necessary nutrition elements and volatile flavor sub-stance.The results showed that the contents of total sugar of oriental tobacco samples from different pro-ducing areas were11.71%-32.18%,the contents of nicotine were0.59%-1.72%,the contents of starch were4.98%-10.65%and extractions of petroleum ether were4.85%-6.50%.The contents of monosaccha-ride were much higher than that of bisaccharide in oriental tobacco.The contents of saccharose were high-er in the bisaccharide.There was little maltose in the air-cured oriental tobacco leaves.The contents of several necessary nutrition elements varied much and were correlated with the contents of sugar and nico-tine differently.The kinds of main flavor components in oriental tobacco from different areas were more or less alike,but the amounts were obviously different.
