The Analysis of Relationship between the Appearance Quality and Sensory Evaluation Index in Flue-cured Tobacco Leaves
摘要
Abstract
The multivariate analysis was done on the relationships between the appearance quality and sensory evaluation index in flue-cured tobacco leaves in Yunnan tobacco-growing areas. The results in-dicated that: (1) Descriptive statistics results showed that the their variable amplitudes were less between the external appearance quality indicators and sensory evaluation index in sample range, Every index average scores belongs to the medium to high level, the coefficient variation was little. (2 ) Relative coefficients results showed that sensory evaluation index in flue-cured tobacco leaves with the appearance quality indicators was significant correlation (P <0. 05) ; ash with the appearance quality indicators relative degree was relatively low. (3 ) Canonical correlation analysis results showed that theCanonical variable I significant difference at 1 % level ( λ1 = 0. 922 6 * * ) , quality of aroma, volume of aroma, concentration, undesirable taste, biting taste, after taste, combustibility and the external appearance quality indicators were close relationship. This linear combination explained the quality of appearance was improved will help to improve the quality of the senses, canonical variable II significant difference at 5% level ( λ2 =0. 745 7 * ) , u2 mainly described the comprehensive character for color of leaves, leaf structure, etc. , v2 mainly described the comprehensive character of ash, concentration, the rest of 4 typical correlation coefficients were not significant. (4) Finally, dual selection stepwise regression equation was constructed for the appearance quality and sensory evaluation index in flue-cured tobacco.关键词
