Application of Factor Analysis in Sensory Evaluation of Tobacco Raw Materials
摘要
[Objective] This study aimed to analyze the main sensory quality indexes of reconstituted tobacco materials. [Method] The factor analysis was performed to analyze sensory quality of reconstituted tobacco raw materials. [Result]The results showed that the contribution rate was 87. 791% and four factors were obtained via factor analysis. The factor loading of factor 1( aroma quality,aroma amount,offensive odor,after-taste) was relatively large. Factor 2 was the exterior factor. Factor 3 was momentum factor. Factor 4 was the concentration factor. The comprehensive scores of samples from different regions demonstrated a descending order of Hubei,Yuxi,Chuxiong,Honghe,Dali,Kunming,Hunan,Henan,Fujian,Qujing,Baoshan,Guizhou,Zhaotong,Chongqing,Puer,Wenshan,Guangdong,and Jiangxi. [Conclusion] The factor analysis results provided a theoretical basis for subsequent sensory evaluation of reconstituted tobacco.
