Relationship Analysis of Smoking Quality and Exterior Feature of Flue- cured Tobacco in Chenzhou

[Objective] To study the relationship of sensory smoking quality and appearance quality of Chenzhou Hunan flue- cured tobacco.[Method]Selecting 90 flue- cured tobacco samples,the appearance quality and sensory evaluation test scores were statistically analyzed.[Result]The results indicated that: tobacco appearance quality indicators and sensory evaluation of the quality of the samples ranged between small,there are some differences of different levels of tobacco in the appearance factors and sensory evaluation,but the variation is a low variability. Sensory irritation index of tobacco smoking and appearance quality indicators of maturity,identity,oil was a significant negatively correlated,concentration and organizational structure was a significant negative correlation. Score of smoking and maturity,development status,identity,oil was a significant positive correlation,with other indicators did not reach the level of significant correlation. By stepwise regression analysis,Chenzhou tobacco smoking area and sensory scores appearance quality indicators multiple regression equation: Y = 42. 213 +0. 971Xmaturity+ 0. 569 Xoil,this equation showed that the smoking quality was positively correlate with the maturity and oil,and these 2 factors had the influence degree of 95% on the smoking quality. [Conclusion] The study can provide a certain theoretical basis for scientific and rational selection of raw tobacco,optimization of leaf formula,rational use of tobacco leaf resource,and improvement of flue-cured tobacco quality.
