恩施主产烟区烤烟质量综合评价

对恩施主产烟区生产的烤烟的物理特性、化学成分、感官质量与中性致香物质含量的状况进行了分析,并在不同产地间进行了比较.结果表明,恩施烤烟拉力较小,厚度、单叶重和叶面密度均较适宜,平衡含水率和含梗率较高;总糖、还原糖、烟碱含量较高,糖碱比值较大,总氮、氯和挥发碱含量较适宜,氮碱比值较低,化学成分尚欠协调;香气质好量足,感官评吸质量较好,烟叶配伍性强,利用价值较高.不同产地闻烤烟的物理特性、化学成分和感官质量均存在显著差异.5大类中性致香物质及其总量均在不同产地间存在显著差异,其中成丰和宣恩的中性物质总量较高.

Quality Evaluation of Flue-cured Tobacco in Main Tobacco-growing Areas of Enshi

The physical characteristics,chemical components,sensory quality and neutral aroma matters in main tobacco-growing areas of Enshi were analyzed and compared.The result indicated that Enshi tobacco had smaller pull,adequate thickness,proper weight per leaf and leaf density,higher equilibrium moisture content and stem ratio;higher total sugar,reducing sugar,nicotine content and the ratio of sugar to alkali;adequate nitrogen,chlorine,total volatile base content;lower nitrogen alkali ratio;so the chemical components was not very concordant;better sense organ quality made Enshi tobacco has stronger compatibility,higher value.The physical characteristics,chemical components and sense organ quality had significant differences in different areas.Five neutral aroma matters and total neutral aroma matters had significant differences in different areas;total neutral aroma matters of Xianfeng and Xuanen were higher than other areas.
