湘西烟叶烟气特性感官评价

Sensory Evaluation on Smoke Characteristics of Tobacco Leaves from Xiangxi Areas

为明确湘西烟叶烟气特性的区域特征和空间分布特征,对来自湘西烟区的41个烟叶样品进行了感官评价。结果表明：（1）湘西烟叶烟气细腻程度为尚细腻,柔和程度为尚柔和,圆润感为尚圆润至稍圆润。（2）烟气细腻程度和圆润感标度值县域间差异不显著;柔和程度标度值县域间差异极显著,主要是古丈县烟叶的烟气柔和程度标度值相对较高。（3）不同乡镇之间以列夕乡烟气细腻程度和圆润感标度值最高,红石林镇的烟气柔和程度标度值最高。（4）K326品种的烟气品质较云烟87品种要好。（5）海拔低于600m烟区的烟叶烟气品质相对较优。（6）烟叶细腻程度、柔和程度、圆润感在空间分布上分别以标度值2.8~2.9分、2.6~2.8分、2.5~2.6分为主要分布;烟气特性评价指标的标度值呈斑块状分布态势。

41 tobacco leaves samples from Xiangxi areas were analyzed by sensory evaluation in order to ascertain the regional characteristics and spatial distribution of smoke characteristics. The results were as follows： （1） The smoke of flue-cured from Xiangxi was a little smoothy, a little softness and a little mellow. （2） There were extremely significant differences among the different counties for the smoke mellow, non-significant differences among the different counties for the smoothy and softness; the smoke mellow of flue-cured tobacco from Guzhang County was relatively higher than others. （3）The scale of smoothy and softness of flue-cured tobacco from Liexi town were the highest among the different towns, while the scale of mellow from Hongshilin town was the highest. （4）The smoke quality of ‘K326’ was better than ‘Yunyan87’. （5） The smoke quality of flue-cured tobacco from plant-tobacco areas under 600m altitude was better than others. （6） The Kriging interpolation map indicated that the spatial distributions of the scale of smoke characteristic indexes were plaque. The 2.8 to 2.9, 2.6 to 2.8 and 2.5 to 2.6 were main distribution of smoothy, softness and mellow, respectively.
