摘要
【目的】分析不同打叶风分单元片烟化学成分的差异性及变化趋势,为打叶后片烟的分类复烤、醇化及工业应用提供参考依据,以期进一步提升烟叶原料的模块化水平、均质化水平和纯净化水平。【方法】以2018年云南石林红大C3F初烤烟叶为研究对象,在打叶工序稳定生产的条件下,对各级打叶风分单元(四级打叶单元11个风分口)分离的片烟进行多次取样,测定其常规化学成分、多酚类化合物和致香成分含量,并进行单因素方差分析和聚类分析。【结果】(1)不同打叶单元及风分口片烟的各项化学成分含量均存在一定的差异性和规律性变化趋势;一级打叶单元片烟的总氮、莨菪亭及醛类致香成分含量较高;二级打叶单元片烟的糖类、总植物碱、绿原酸和芸香苷含量较高;三级打叶单元片烟的醇类、酮类和酯类致香成分含量较高;四级打叶单元片烟的钾、氯及酸类致香成分含量较高。(2)三类化学指标的聚类结果显示:四级打叶单元11个风分口的片烟样品可以聚成三大类,分别为一级和二级打叶单元、三级打叶单元以及四级打叶单元。【结论】不同打叶风分单元的片烟内在化学品质存在明显的分类现象,可以为分类复烤和差异性醇化工艺的改进提供参考依据。
[Purpose]Differences and trends of chemical constituents of tobacco strips separated from different threshing and pneumatic separation units were analyzed to provide reference for classified redrying,aging and industrial application of tobacco after threshing and further improve the mod-ularization,homogenization and purification level of tobacco raw materials.[Method]The fluecured tobacco of Hongda C3F in Shilin,Yunnan Province in 2018 was taken as the research objects.Under the condition of stable production in threshing process,tobacco strips separated from different threshing and pneumatic separation units were sampled many times and their routine chemical components,polyphenols and aromatic components were determined.In the end,single factor variance analysis and cluster analysis were conducted.[Results](1)There were some differences and regularities in the contents of various chemical components in tobacco strips separated from different threshing and pneumatic separation units.The contents of total nitrogen,scopolamine and aldehydes were higher in tobacco strips in the first threshing and pneumatic separation units.The contents of sugars,nicotine,chlorogenic acid and rutin were higher in tobacco strips in the second threshing and pneumatic separation units.The contents of alcohols,ketones and esters were higher in tobacco strips in the third threshing and pneumatic separation units.The contents of potassium,chlorine and acid aromatic compounds were higher in tobacco strips in the fourth threshing and pneumatic separation units.(2)According to the results of the cluster analysis based on the above three kinds of chemical indexes and the strips samples from eleven separators of four threshing units could be divided into three categories(the first and second threshing units,the third threshing units,and the fourth threshing units).[Conclusion]There are obvious classification phenomena in the inherent chemical quality of tobacco strips with different threshing and pneumatic separation units,which can provide reference for the improvement of classified redrying and differential aging processes.
