Abstract

Abstract: In order to explore the effect of tobacco essential oil microcapsules on cigarette paper flavoring，firstly，tobacco essential oil was prepared by water distillation. Then complex coacervation method was employed to prepare tobacco essential oil microcapsules with tobacco essential oil as the core material，chitosan as the wall material，and span⁃80 as the emulsifier，and the embedding yield was determined.Subsequently，scanning electron microscopy，laser particle size analyzer and infrared spectrum analyzer were used to characterize the physical and chemical properties of microcapsules.Finally，the microcapsules were used to flavor cigarette paper，and the sensory evaluation and smoke composition analysis of the flavored cigarettes were carried out.The results showed that the average particle size of tobacco essential oil microcapsules prepared with chitosan as the wall material and tobacco essential oil as the core material was 221. 1 nm，and the embedding yield was 75.3%.The prepared tobacco essential oil microcapsules showed smooth and plump spherical surface through scanning electron microscope.The infrared spectrum analysis of tobacco essential oil，chitosan and tobacco essential oil microcapsules showed that tobacco essential oil was embedded in chitosan by comparing their characteristic absorption peaks.The results of sensory evaluation showed that the flavored cigarettes were significantly improved.When the tobacco essential oil microcapsules and tobacco essential oil were compounded at a volume ratio of 1∶2，the aroma effect was more significant，and the sensory evaluation score could reach 86.6.Compared with the control（ie.cigarettes without flavoring），the contents of nicotine，alcohols，aldehydes，acids，esters and ketones in the smoke components of the cigarettes with compound flavors were increased，and the aroma，taste and strength of cigarettes were improved.

摘要： 为探究烟草精油微胶囊在卷烟纸加香的效果，首先通过水中蒸馏法制备烟草精油，采用复凝聚法，以烟草精油为芯材、壳聚糖为壁材、司班-80为乳化剂，制备烟草精油微胶囊并测定包埋产率，然后采用扫描电子显微镜、激光粒度仪和红外光谱分析仪等对微胶囊的物理化学性质进行表征，最后将微胶囊进行卷烟纸加香并对加香后的卷烟进行感官评价和烟气成分分析。结果表明，以壳聚糖为壁材、烟草精油为芯材制备烟草精油微胶囊的平均粒径为221.1 nm，包埋产率为75.3%。通过扫描电子显微镜对制备的烟草精油微胶囊观察发现，其呈现表面光滑饱满的球状。对烟草精油、壳聚糖和烟草精油微胶囊进行红外光谱分析，通过对比三者的特征吸收峰可以证明烟草精油被包埋在壳聚糖中。感官评吸结果表明，加香后的卷烟感官质量均有明显改善。烟草精油微胶囊与烟草精油按体积比1∶2复配后加香效果更为显著，感官评吸得分可达86.6。与未加香空白组卷烟相比，添加复配溶液的卷烟烟气成分中烟碱、醇类、醛类、酸类、酯类、酮类成分的含量均有提高，卷烟香味、吃味和劲头均得到改善。
