摘　　要：为了提高得率,获得烤香浓郁的烟草香料,使用过热水蒸气蒸馏-干馏集成技术制备烟草香料,比较了水蒸气蒸馏法、干馏法与过热水蒸气蒸馏-干馏集成技术在得率、物质组成、香气特征及品吸口感方面的差异,结果表明:(1)水蒸气蒸馏法得率为0.11%,主要化学成分为新植二烯(44.88%)、茄酮(10.14%),其香气特征以清香、草香为主,缺乏烤香、焦甜香。(2)干馏法得率为1.17%,主要化学成分为烟碱(24.77%)、糠醇(6.69%)、甲基环戊烯醇酮(1.14%),香气较丰富,呈现烤甜香。(3)过热水蒸气蒸馏-干馏集成技术得率为10.98%,主要化学成分为烟碱(25.84%)、甲基环戊烯醇酮(7.11%)、糠醇(6.72%)、乙基环戊烯醇酮(5.59%)、糠醛(4.51%)、愈创木酚(4.45%),香气丰富,烟气成团性好,刺激和杂气减少。过热水蒸气蒸馏-干馏集成技术可得到不同香气风格的烟草干馏香料,用于加热卷烟中提升了抽吸品质,在大幅度提高得率的同时解决了单一提取方法下烤香味不足及容易焦糊等问题。In order to increase the yield,get tobacco spices with strong roasted aroma,tobacco flavors were extracted by the superheated steam distillation-cracking process integrated technology,the yield,substance composition,aroma characteristics and taste of the steam distillation,cracking process and superheated steam distillation-cracking process integrated technology were analyzed and compared.The results showed that:(1)the yield of steam distillation method was 0.11%,the main substances obtained by steam distillation were neophytadiene(44.88%)and solanone(10.14%).Its aroma characteristics were mainly fragrant and grassy,lacking roasted aroma and burnt-sweet aroma;(2)The yield of cracking process was 1.17%,the main substances obtained by cracking process were nicotine(24.77%),furfuryl alcohol(6.69%),methyl cyclopentenolone(1.14%),etc.The aroma was rich;(3)The yield of integrated technology of superheated steam distillation-cracking process was 10.98%,the main substance obtained by the integrated technology were nicotine(25.84%),Methylcyclopentenolone(7.11%),furfuryl alcoho l(6.72%),3-Ethyl-2-hydroxy-2-cyclopenten-1-one(5.59%),furfural(4.51%),guaiacol(4.45%),the aroma was more abundant.This technology can obtain tobacco cracking process flavors with different aroma styles,which can be used in heating cigarettes to improve the smoking quality.While greatly improving the yield,it solves the problems of insufficient roasted flavor and excessive burnt flavor with a single extraction method.
