| 摘 要： | 目的]对云南大理烤烟的外观质量与感官质量的相关性进行分析。方法]以云南大理烤烟仿制样品为材料,根据GB2635-92烤烟分级标准及有关研究结果,对37个等级烟叶外观质量和感官质量进行综合量化评价,并对数据是否具有参考价值进行统计分析,在此基础上运用简单相关分析和典型相关分析对各项指标间的相关性进行分析。结果]所选37个样品外观质量存在着广泛的变异,感官评价结果符合正态分布,具有较大的参考价值。简单相关分析结果显示,外观质量中的颜色、成熟度、油分、色度及外观总分分别和感官质量中的香气质、香气量、浓度、劲头、杂气、刺激性、余味、燃烧性、灰色及评吸总分之间均存在极显著正相关关系;典型相关分析与简单相关分析的结果基本一致,外观质量与感官评吸各指标之间的关系可概括为2对典型变量内部之间的关系2,对典型变量的典型相关系数分别为0.972 6(P0.01)和0.848 8(P0.01)。结论]该研究可为我国烤烟质量评价体系的建立和优质烤烟的生产提供参考。 |

| Abstract: | Objective]The aim was to study the correlation between the appearance quality and sensory quality of Yunnan-Dali flue-cured tobacco.Method] The appearance and sensory qualities of 37 levels of tobacco cultivated in Dali,Yunnan Province were quantitatively evaluated in terms of the National Tobacco Grading Standard(GB2635-92).A statistical analysis was also conducted to examine whether the data delivers indicative reference values.The correlations among indicators were assessed using simple correlation analysis and canonical correlation analysis.Result] The results indicate that while the selected 37 levels of tobacco vary in appearance quality,the evaluation of sensory quality shows a normal distribution.The appearance qualities are indicative in assessing the sensory qualities.According to the simple correlation analysis,the appearance qualities,including color,maturity,oil content,chromaticity,and total score appearance qualities,are significantly and positively related to each of the following sensory qualities,i.e.,aromatic quality,aromatic quantity,thickness,strength,offensive odor,irritation,aftertaste,combustibility,color of ash,and total score of sensory qualities.The result derived from the canonical correlation analysis is basically consistent with that of simple correlation analysis.The correlation between appearance qualities and sensory qualities can be summarized as a correlation between two sets of canonical variables,with canonical correlation coefficients of 0.972 6(P<0.01)and 0.848 8(P<0.01),respectively.Conclusion]The study provides reference for establishing the quality evaluation system of flue-cured tobacco and production of high quality flue-cured tobacco. |
