基于主成分分析和聚类分析的再造烟叶综合品质评价

Comprehensive Quality Evaluation of Reconstructed Tobacco Leaves Based on Principal Component Analysis and Cluster Analysis

为探究再造烟叶综合品质评价的关键指标,并建立品质评价方法体系,选取不同类型的再造烟叶共12种,对其进行了理化指标、致香成分的测定和感官质量的评价。针对测定结果,运用相关性分析、主成分分析,筛选出再造烟叶品质评价的10个关键性指标,对数据进行分析处理后,得到再造烟叶综合评价模型,可对再造烟叶综合品质进行量化。结合聚类分析结果,发现综合评价模型有效,且与感官评价结果一致。本文的研究结果为再造烟叶综合品质的量化评价和加工工艺研究提供了较为科学的理论基础和科学依据。

In order to explore the key indicators for comprehensive quality evaluation of reconstituted tobacco leaves and establish a quality evaluation method system,a total of 12 different types of reconstituted tobacco leaves were selected,and their physical and chemical indicators,aroma components,and sensory quality were measured.Based on the measurement results,correlation analysis and principal component analysis were used to select 10 key indicators for evaluating the quality of reconstituted tobacco leaves.After analyzing and processing the data,a comprehensive evaluation model for reconstituted tobacco leaves has been obtained,which can quantify the comprehensive quality of reconstituted tobacco leaves.Based on the clustering analysis results,it was found that the comprehensive evaluation model is effective and consistent with the sensory evaluation results.The research results of this article provide a scientific theoretical basis and scientific basis for the quantitative evaluation of the comprehensive quality of reconstituted tobacco leaves and the study of processing technology.
