摘要： 采用气质联用仪对四川省6种白肋烟晾房(竹笆涂泥晾房、全板晾房、黑膜夹草晾房、全黑膜晾房、黑膜推杆晾棚、小青瓦晾房)晾制后烟叶中性香气成分进行了定量分析,并卷制单料烟进行感官评吸以确定最有利于提高白肋烟香气质量的晾房种类。结果表明,不同晾房晾制的中部叶总中性物质含量的排序为竹笆涂泥晾房>黑膜夹草晾房>全黑膜晾房>黑膜推杆晾房>全板晾房>小青瓦晾房,上部叶的排序为竹笆涂泥晾房>黑膜夹草晾房>黑膜推杆晾房>全板晾房>全黑膜晾房>小青瓦晾房,去除新植二烯后以黑膜推杆晾房晾制的烟叶总中性香气物质含量最低。竹笆涂泥晾房和黑膜夹草晾房巨豆三烯酮、大马酮、二氢猕猴桃内酯等主要类胡萝卜素类降解成分、茄酮及上部叶的氨基酸和糖类降解产物都较高,小青瓦和全板晾房晾制的中部叶总中性香气成分和上部叶类胡萝卜素降解成分含量多处于较低水平,黑膜推杆晾房和全黑膜晾房烟叶西柏三烯降解产生的茄酮含量显著低于其他晾房。中部叶感官评吸得分排序为竹笆涂泥晾房>黑膜夹草晾房>全黑膜晾房>黑膜推杆晾房>全板晾房>小青瓦晾房。

Abstract: GC/MS was used to analyze the contents of neutral aroma components for upper and middle stalk position air-cured leaves from 6 different curing barns, and experimental cigarettes were made to conduct sensory evaluation.Results showed that the total contents of neutral volatile aroma components for middle position leaves followed the order of bamboo-mud barn＞black plastic with grass barn＞all-black plastic barn＞plastic covering structure＞wooden plate barn＞tile-roofed barn, and for upper position leaves the order was bamboo-mud barn＞black plastic with grass barn＞plastic covering structure＞wooden plate barn＞all-black plastic barn＞tile-roofed barn.When neophytadiene was deducted from the total, the lowest level was for plastic curing structure.High contents of carotenoid catabolites ( megastigmatrieonel,β-damascone et al) and cembratriendiol catabolite ( solanone) in both stalk position leaves, and phenylalanine and sugar catabolites in upper stalk position leaves were found for bamboo-mud barn and black plastic with grass barn.Lower levels of aroma components in middle stalk position leaves and carotenoid catabolites in upper stalk position leaves were found for wooden plate barn and tile-roofed barn.The lowest content of solanone was found in cured leaves from plastic covering structure and all-black plastic barn.The sensory evaluation score followed the order of bamboo-mud barn＞black plastic with grass barn＞all-black plastic barn＞plastic covering structure＞wooden plate barn＞tile-roofed barn．
