低次烟叶发酵制备烟草香料的研究
Preparation of tobacco flavor from discarded tobacco leaves by fermentation
-
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.Abstract: The tobacco concrete from discarded tobacco leaves were prepared by fermentation of aroma producing 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℃ for 7 d.The flavor was extracted by simultaneous distillation extraction and the volatile components of extract were analyzed by GC-MS.Comparing with common tobacco extract,the special aroma components of the extract were:5-methyl furfural,β-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 aroma 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.
