密集烘烤不同装烟方式对烤后烟叶中性致香物质含量的影响

Effects of Different Loading Methods on Aroma Content in Bulk Curing Barn

为了探索密集烤房不同装烟方式与烤后烟叶香气物质的关系,进行了密集烤房挂竿、散叶、插签和烟夹4种装烟方式的试验。结果表明:1)不同装烟方式烤后烟叶中性致香物质总含量大小为散叶>插签>挂竿>烟夹,与挂竿处理相比,散叶处理的中性致香物质总量增加了10.94%,插签处理增加了8.48%。2)散叶处理在类胡萝卜素降解产物类、棕色化反应产物类、苯丙氨酸降解产物类、类西柏烷降解产物类以及新植二烯等香气成分类上均有增加;插签处理的中性香气物质增加主要在类胡萝卜素降解产物类、新植二烯含量上,分别增加了8.54%和12.16%;烟夹处理苯丙氨酸类致香物质的苯甲醛、苯甲醇、苯乙醛、苯乙醇含量均有所增加。综合认为,散叶和插签装烟方式可以增加烤后烟叶的中性致香成分含量,烟叶的香气物质含量与装烟方式密切相关。

Abstract： The aroma constituents were tested by using four types of tobacco loading, including common loading leaf with pole, loose-leaf accumulation, sticking tobacco leaves and loading leaf with clip, in order to investigate the relationship of different loading method and aroma constituents of tobacco leaves in bulk curing barn. Results： 1） The content sequence of neutral aroma constituents was loose-leaf sticking^pole~ clip, compared with common loading leaf with pole, the neutral aroma constituents of loose-leaf accumulation and sticking tobacco leaves were increased by 10.94% and 8.48% respectively. 2） Loose-leaf accumulation increased the contents of degraded carotenoid products, maillard reaction products, phenylalanine products, cembratriendiol products and neophytadiene, sticking tobacco leaves increased the contents of degraded carotenoid products and neophytadiene by 8.54%, 12.16% respectively; clip increased the contents of phenylalanine products（benzal dehyde, benzal alcohol, phenyl acetaldehyde and phyenyl ethylalcohol）. In general, the aroma constituents were increased in loading of loose-leaf accumulation and sticking tobacco leaves, the aroma constituents of tobacco leave had a close affinity to loading method.
