湖南浓香型产区烟叶的香气特性

为明确湖南浓香型产区烟叶香气特性评价指标的区域特征和空间分布特征，对来自湖南烟区的44个烟叶样品进行感官评价。结果表明：①湖南浓香型产区烟叶香气质尚好至较好，香气量尚足至较足，香气尚透发至较透发，微有枯焦气和木质气；②不同地区之间香气质差异显著，香气量、透发性、枯焦气和木质气则无统计学差异；③香气质呈从东南部向西北部递减的趋势分布，香气量呈从南部向北部递减的趋势分布，透发性呈从东北部向西南部递减的趋势分布，枯焦气呈从东北部、西南部分别向中部递减的趋势分布，木质气呈从东北部向南部递减的趋势分布；榆香气质、香气量和透发性年度间较稳定，枯焦气和木质气年度间有差异。

Aromatic Characteristics Distribution of Burnt-sweetness Type Tobacco Leaves from Hunan Province

44 tobacco leaves samples from Hunan burnt-sweetness type tobacco-growing areas were analyzed by sensory e-valuation in order to ascertain the regional characteristics and spatial distribution of aroma characteristics. The results were as follows：①The aroma quality of flue-cured from Hunan burnt-sweetness type tobacco-growing areas was from less good to good, characterized as aroma quantity was from much to more;the diffusiveness was from less good to good;the ligne-ous odour and scorched odour were tiny. ②There were significant differences among the different prefectures for the aroma quality, non-significant differences among the different counties for the aroma quantity, diffusiveness, ligneous odour and scorched odour. ③The Kriging interpolation map indicated that the spatial distributions of the scale of aroma quality with a trend that decreased from southeast to northwest, that of aroma quantity with a trend that decreased from south to north, that diffusiveness with a trend that decreased from northeast to westsouth, that of scorched odour with a trend that de-creased from both northeast and southwest to central region, that of ligneous odour with a trend that decreased from north-east to south. ④Aroma quality, aroma quantity and diffusiveness were annual stability, scorched odour and ligneous odour were annual decrease.
