摘　　要：以低次烟叶为原材料,将其水提物,添加10%的葡萄糖,接种1%的金星产香酵母SP—3,灭菌后在30℃的条件下发酵7 d,制备出特色烟草浸膏.采用同时蒸馏萃取法萃取烟草浸膏的致香成分,并利用气相色谱-质谱联用进行分析.结果表明该特色烟草浸膏中有5-甲基糠醛、β-苯乙醇、乙酰基吡咯、巨豆三烯酮、3-甲基吲哚等特殊香味成分.在100 g烟丝中,添加0.01～0.05 g的特色烟草浸膏能与烟香谐调,增大香气量,烟气柔和细腻、余味纯净,比没有经过发酵的普通烟草浸膏的加香效果更好.The tobacco concrete from discarded tobacco leaves were prepared by fermentation of aroma pro- ducing yeast XINJING SP-3. The process was as following： extract of discarded tobacco leaves was added 10% glucose and 1% yeast. After sterilization, the tobacco extract was fermented at 30 ~C for 7 d. The fla- vor was extracted by simultaneous distillation extraction and the volatile components of extract were ana- lyzed by GC-MS. Comparing with common tobacco extract, the special aroma components of the extract were ： 5-methyl furfural,/3-phenyl ethyl alcohol, acetyl pyrrole, megastigmatrienone, 3-methyl indole, etc. Addition of 0.01 g to 0.05 g special tobacco flavor to 100 g cigarette could augment and enhance the aro- ma and taste of smoking tobacco and reduce irritancy of the smoking cigarette. The special tobacco flavor could preferably improve the aroma property of tobacco than the normal tobacco flavor.
