摘要
为了明确重庆烟区不同鲜烟叶处理技术对烤烟中性香气物质含量的影响,以云烟97为材料,研究了摘除下部烟叶(0、2、3和4片)对烤烟中性香气物质的影响。结果表明,摘除2片能显著提高上部叶的类胡萝卜素降解产物和新植二烯的含量,但也显著降低了中部叶的苯丙氨酸类、类西柏烷降解产物和类胡萝卜素降解产物含量;摘除3片能显著提高中部叶的苯丙氨酸类、类胡萝卜素降解产物和新植二烯含量,同时对上部叶的苯丙氨酸类、棕色化产物类和类西柏烷降解产物含量的提高有显著的促进作用,但也显著降低了中部叶棕色化产物含量;摘除4片显著提高了中部叶棕色化产物和类西柏烷降解产物的含量,但显著降低了上部叶的苯丙氨酸类和类胡萝卜素降解产物含量。致香物质总量显示,不同处理间存在极显著差异,其中,中部叶以摘除3片含量最高,摘除4片次之,对照最低;上部叶含量依次为摘除2片>摘除3片>对照>摘除4片。因此认为,在该生态条件下摘除下部鲜烟叶时以3片为宜。
The objectives of this study were to investigate the effects ofthenumber ofunusablefresh leavesremovedon neutral aroma composition of flue-cured tobacco. A field experimentwith four treatment level（0, 2, 3, and 4leaves removed）was carried outby usingYunyan 97. The results indicated thatthe content ofcarotenoid andneophytadiene in upper leavessignificantly increasedwhen two leaves removed, butthe content ofphenylalanine,vembratriendiol,varotenoid in middle leavessignificantly decreased. The content ofphenylalanine,carotenoid,neophytadiene in middle leaves, and the content ofphenylalanine,maillard reaction products,cembratriendiol in upper leavessignificantlyincreasedwhen 3 leaves removed, butthe content ofmaillard reaction productsinmiddle leavesdecreased significantly. The content ofmaillard reaction products andcembratriendiol in middle leavessignificantlyincreasedwhen 4 leavesremoved,butthephenylalanine andcarotenoid in upper leaves decreased. The total content of neutral aroma componentinflue-cured tobacco wassignificantlyimproveddue toremoval ofthe fresh leaves. The content in middle leavesfrom high to low was： 3leaf removal 〉 3 leaf removal〉 2 leaf removal〉no removal. For upper leaves,the order was 2 leaf removal 〉 3 leaf removal 〉 0 removal〉 4 removal.Therefore,we suggest the 3 leaf removal is the best option.
