河南烤烟主要化学成分与吸食品质的关系

Relationship between Major Chemicals of Flue-cured Tobacco and Its Smoking Quality in Henan Province

通过对河南5个烟叶产地150份烟叶样品的检测分析,发现河南烟叶总体上属于"浓偏中和中偏浓"香型,典型的浓香型有所淡化。相对而言,平顶山、驻马店烟叶浓香风格比较明显。河南烟叶烟碱、氮碱比、糖碱比以及硫含量与烟叶浓香风格彰显程度之间存在较明显的规律性关系。统计结果显示,在一定范围内,河南烟叶烟碱、总氮、两糖比与吸食质量水平之间呈极显著的负相关关系;总糖含量、还原糖含量、糖碱比和氮碱比与吸食质量水平之间呈极显著的正相关关系。并分析了河南烟叶浓香特征彰显程度较高时和吸食质量水平较高时的烟叶主要化学成分适宜区间。

We collected 150 leaf samples of flue-cured tobacco from five counties in Henan Province and tested their major chemical components and smoking quality. The results showed the odor types of Henan flue-cured tobacco were full-bodied, but some of them were no longer typical. The odor type of flue-cured tobacco in Pingdingshan and Zhumadian were more typical. There were close relationships between the nicotine contents, the ratio of total nitrogen contents to the nicotine, the ratio of the total sugar contents to the nicotine and the sulphur contents. The statistical results showed that there were significant negative correlation between the nicotine contents, total nitrogen contents, the ratio of the reducing sugar contents to total sugar and the smoking quality, significant positive correlation between the total sugar contents, the reducing sugar contents, the ratio of the total sugar contents to nicotine and the smoking quality within the specific limits, and all of their correlation were significant at 1% level. The chemical components suitable ranges were discussed when their odor type were more typical and had upper smoking quality.
