摘要
为探讨碳酸钾（K2CO3）对烟丝中挥发性、半挥发性香味成分含量的影响,采用实验室模拟烘丝,按烟丝质量0.5％,0.9％,1.3％,1.7％和2.1％的用量将K2CO3水溶液均匀施加于烟丝,平衡48 h后,于设定条件（温度110℃,风速1.57 m/s和转速12 r/min）下烘丝至含水率为12％～13％,再用甲基叔丁基醚萃取烟丝并进行GC/MS检测.结果表明：①K2CO3对烟丝的外观有显著影响,当施加比例超过烟丝质量的1.3％时,部分烟丝变黑;②加入K2CO3后,烟丝中酯类、酸类组分含量呈规律性降低趋势;醇类组分和巨豆三烯酮类组分含量增加.
In order to investigate the effects of potassium carbonate （K2CO3） addition on the volatile and semi-volatile aroma component content in cut tobacco,cut tobacco drying was simulated in a laboratory,K2CO3 solution was uniformly sprayed on tobacco at levels of 0.5％,0.9％,1.3％,1.7％,and 2.1％ （w/w） separately.After equilibrium for 48 hours,tobacco was dried at the set conditions （temperature 110 ℃,air velocity 1.57 rn/sec and rotating speed 12 r/min） to moisture content of 12％-13％,then extracted with tert-butyl methyl ether and determined by GC/MS.The results showed that：1） the appearance of tobacco was significantly affected by K2CO3,some cut tobacco turned black when the addition rate of K2CO3 exceeded 1.3％ （w/w）.2） K2CO3 addition decreased the contents of esters and organic acids in tobacco regularly,increased the contents of alcohols and megastigmatrienones.
