| 摘 要： | 利用河南省郏县步进式烤房研究了变黄期与定色期拉长烘烤时间对烟叶中性致香成分含量的影响。结果表明：①拉长了变黄和定色时间的3个处理T2,T3,T4均提高了烟叶中性致香成分总量；②苯丙氨酸类、类胡萝卜素类、类西柏烷类、新植二烯类致香物质含量在42℃变黄拉长12 h处理(T2)最高；定色期54℃定色拉长12 h的处理(T3)较正常烘烤处理(T1)只提高了类胡萝卜素类及新植二烯类产物含量；在变黄期与定色期均拉长12 h处理(T4)的棕色化产物含量在4个处理中最高,且T4处理与正常烘烤处理T1相比,苯丙氨酸类、类胡萝卜素类、新植二烯类致香物质含量提高,类西柏烷类物质含量降低。

| Abstract: | Using the stepping flue\|curing bam in Henan, effects of prolonging the time of yellowing and leaf drying on neutral aroma constituents of tobacco leaves during curing were studied. The results indicated as follows:① All of the treatments which prolonged the time of yellowing and leaf drying could increase the content of neutral aroma constituents.② The content of phenylalanine products, carotenoid, cemdrenoid, neopytadiene were highest in the treatment of T2 which prolonged the time of yellowing; Compared with normal cured treatment T1, T3 which prolonged the time of leaf drying only increased the content of carotenoid and neopytadiene. The content of maillard reaction products were the highest in the treatment of T4 which prolonged the time of yellowing and leaf drying. Compared with T1, the contents of phenylalanine products, carotenoid, neopytadiene increased and the content of cemdrenoid decreased in treatment of T4． |
