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

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 evalu-ation 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 flue-cured tobacco raw materials were in line with the quality of Yun-nan tobacco; The total sugar and reducing sugar of H4 brand cured tobacco were higher than of the high quality tobacco leaves 0.76% and 10.3%, 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 nitro-gen, 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.%[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。
