基于卷烟品牌的云南省烟叶基地烟叶常规化学成分隶属度评价

　　摘要 [目的]研究云南中烟基地单元烟叶的内在化学成分质量状况。[方法]采集76个在滇原料基地的C3F烟叶样品并进行常规化学成分分析，采用基于云南中烟卷烟品牌H1、H2的隶属函数及层次聚类分析进行评价。[结果]76个基地单元主要化学成分总体协调。H1品牌烤烟原料总氮比优质烟叶高12.08%；H2、H3品牌烤烟原料符合云南优质烟叶标准；H4品牌烤烟原料总糖、还原糖分别比优质烟叶高0.76%、10.3%。烟叶总糖、还原糖、钾，G1集团基地分别比G2集团基地高38.1%、2.27%、7.34%；总氮、氯分别低4.69%和11.11%；烟碱相近。H2与H3主要化学成分差异不显著；H3与H4主要化学成分除总氮差异显著外，其余差异均不显著；H4与H2无显著差异。[结论]G2和G1集团基地单元烟叶较优，可为基地单元的建设提供理论参考。

　　Abstract [Objective] The aim was to understand the quality of the chemical components of tobacco in Yunnan Province. [Method] The C3F samples were collected from 76 base units in Yunnan Province and their conventional chemical components were analyzed， and the evaluation was carried out based on the membership function and hierarchical cluster analysis of cigarette brand H1 and H2 in Yunnan. [Result] The results showed that major chemical components of 76 base units were of totally coordination. The total nitrogen of the H1 brand was higher than that of the high quality tobacco leaves 12.08%； H3 and H2 brand fluecured tobacco raw materials were in line with the quality of Yunnan tobacco； The total sugar and reducing sugar of H4 brand cured tobacco were higher than of the high quality tobacco leaves 0.76% and 103%， respectively. The total sugar， reducing sugar and potassium of tobacco leaves of G1 Group base were high than that of G2 Group base 38.1% and 2.27%， 7.34%， respectively； total nitrogen and chlorine were low 4.69% and 11.11%； nicotine is similar. The main chemical components of H2 and H3 were not significant； The main chemical components of H3 and H4 were significantly different from the total nitrogen， the rest were not significant； No significant differences between H4 and H2. [Conclusion] The leaves quality of tobacco base unit of G2 groups were better than that of G1 groups. Therefore， the evaluation provides a theoretical reference for the construction of the base unit.

　　烟叶中主要化学成分的含量及其比值，在很大程度上决定了烟叶及其制品的烟气特征，直接影响烟叶品质的优劣[1]。云南省是我国优质烤烟产区，也是我国最大的烟叶产地[1]。云南地处低纬度高原，光照充足，气温变化稳定，雨量适中，雨热同季；所产烟叶色泽金黄，组织细致，油润丰满，吸味清香、醇和，是重要的卷烟原料。不同地区的气候、土壤营养和栽培技术条件不同，所产烟叶的化学成分存在较大变异[2-3]。应用化学指标对烟叶质量进行科学评价，对卷烟工业合理利用烟叶具有重要意义[4]。对烟叶质量的综合评价方法主要有模糊概率[5-8]、灰色系统理论[9]、聚类分析[10]等，但基于卷烟品牌的隶属度研究鲜见报道。笔者对云南76个基地单元烟叶化学成分进行基于卷烟品牌隶属度的评价分析，以期为云南烟叶原料基地单元建设和卷烟工业企业选择和利用烟叶原料提供依据。
