不同装烟密度对烤后烟叶品质和评吸质量影响 　　摘 要：为了研究装烟密度对烤后烟叶品质及评吸质量的影响，为密集烤房烘烤工艺完善提供依据，设低密度（装鲜烟50kg/m3） 、中密度（装鲜烟60kg/m3） 、高密度（装鲜烟70kg/m3） 3个装烟密度，对比分析了装烟密度对烤后烟叶外观质量、经济性状、化学成分及感官评吸品质的影响。结果表明：（1） 装烟密度为中密度时，烟叶结构疏松，颜色金黄至橘黄，色度强，烤后烟叶的外观质量表现较好。（2）装烟密度为中密度时，上等烟和中等烟比例最高，均价最高，经济效益最高。（3）提高装烟密度能够极显著地降低烟叶还原糖和淀粉的含量，中密度处理的糖碱比表现最好，最为接近优质烟叶标准。（4）中密度处理的烟叶香气量和劲头最好，感官评吸质量最佳。综合认为，烤烟密度为60kg/m3时最佳。 关键词：装烟密度；烟叶品质；评吸质量 中图分类号 S572 文献标识码 A 文章编号 1007-7731（2013）15-126-03 The Effect of Different Loading Density on Tobacco Quality and Sensory Evaluation Quality Zhang Peng （China Tobacco Shandong Indusrial Co.，Ltd.，Jinan 250100，China ） Abstract：In order to study the effect of loading density on tobacco chemical components and smoking quality，we designed three different loading densities（50kg/m3，60kg/m3 and 70kg/m3） and tried to identify the best one for tobacco quality. The results were as follows：（1） in the medium loading density，tobacco leaf structure was loose，the color was yellow to orange，and the appearance of the tobacco leaf quality performance was better.（2） In the medium loading density，the rate of high-grade and middle-grade tobacco leaves was highest among these three different treatments，and the economic return was also better.（3） Improving the smoke density could significantly reduce tobacco reducing sugar and starch content. The sugar/nicotine ratio of medium density treatment was the best.（4） In the medium loading density，tobacco aroma and momentum were the best，sensory evaluation scores highest quality. Comprehensive thought，flue-cured tobacco best when density is 60kg/m3.
