河南烟区烤烟中性致香物质的区域分布

Regional distribution of neutral aroma components of flue-cured tobacco leaves in Henan province

以2011—2013年河南7个烟区26个样点的烤烟C3F烟样为材料,研究烤烟中性致香物质的区域分布。结果表明:洛阳烟区烤烟的类胡萝卜素降解产物含量较低(芳樟醇和巨豆三烯酮3除外),棕色化产物含量也较低(2–乙酰基吡咯、5–甲基糠醛除外);许昌烟区烤烟的其他苯丙氨酸类物质含量较高(苯甲醇除外);南阳和三门峡烟区烤烟的茄酮含量显著低于驻马店烟区的,显著高于漯河烟区;各烟区烤烟新植二烯含量差异无统计学意义;中性致香物质总得分呈现南高北低、西低东高的规律。

The regional differences of neutral aroma components of flue-cured tobacco leaves were studied on C3F tobacco samples collected from 26 sampling points in Henan from 2011 to 2013. The results showed that the contents of carotenoid degradation products in tobacco leaves from Luoyang except linalool and megastigmatrienone3 were all significantly lower compared to other regions; the contents of Millard reaction components of Luoyang except 2-acetyl pyrrole and 5-methyl furfural were also significantly lower. The contents of PHE degradation products in tobacco leaves from Xuchang except benzyl alcohol were significantly higher than those from other regions. The solanone contents in tobacco leaves from Nanyang and Sanmenxia were both significantly lower than those from Zhumadian while higher than those of Luohe. The neophytadiene contents in tobacco leaves showed no significant difference among different sampling points. The total scores of neutral aroma components in tobacco leaves from the South were high, from the North were low while those from the East were high, from the West were low.
