摘　　要：为了解脱氧果糖嗪(DOF)的加香效果和使用剂量,对其在烤烟、烤烟叶组、白肋烟叶组、市售低焦油烤烟型卷烟和混合型卷烟、通风滤嘴和加长滤嘴低焦油烤烟型卷烟中的加香效果进行了感官评价,并采用GC/MS法分析了DOF在300、600、900℃下的热裂解产物及添加DOF卷烟主流烟气中的碱性香味成分。结果显示:对烤烟和烤烟叶组,DOF在丰富烟香浓度,改善细腻柔和程度方面有作用,适宜用量20μg/g;对白肋烟叶组,DOF在改善烟气细腻柔和程度,增强凝聚性方面作用较为明显,适宜用量50～100μg/g;市售低焦油烤烟型卷烟(盒标焦油8mg/支)和混合型卷烟(盒标焦油10mg/支)中加入DOF,其香气、谐调、刺激性和余味方面均有所改善;通风滤嘴和加长滤嘴低焦油卷烟中添加DOF,香气量、回甜感和余味方面均有明显改善,干燥程度等方面也有不同程度的改善;DOF的增香机理是,燃吸过程中DOF发生热裂解,释放出大量吡嗪类、吡啶类等小分子重要香味化合物,从而起到增进香气改善吸味的作用。In order to investigate the flavoring effects and dose of deoxyfructosazine （DOF） application, the DOF - added samples of flue-cured tobacco, blended flue-cured tobacco, blended hurley tobacco, commercial low tar Virginia type cigarette and blended cigarette, and low tar Virginia type cigarette with ventilated filter and that with long filter were evaluated. The pyrolysis products of DOF at 300, 600, 900℃ and the basic aroma constituents in mainstream smoke of cigarettes applied with DOF were analyzed by GC/MS. The results were as follows： the recommendable doses of DOF for flue-cured tobacco and blended flue-cured tobacco, blended hurley tobacco, and low tar cigarettes with ventilated filter or long filter were 20, 50-100, and 5-20 μg/g, respectively, at which the smoke aroma was improved, irritation was reduced, and sweetness and aftertaste were increased. The flavoring mechanism of DOF was that a substantial amount of important aroma compounds of pyrazines and pyridines were released from the pyrolysis of DOF during smoking which enhanced smoke aroma and aftertaste.
