研究烟草香精微胶囊化后在加热卷烟中的应用效果，采用复凝聚法制备烟草香精亚微米微胶囊，优化制备工艺，表征理化特性，并研究其在加热卷烟降温段的感官效果，以及在气溶胶中逐口释放行为。结果表明：（1）复凝聚法制备烟草香精亚微米微胶囊最佳工艺条件为，壳聚糖量0.18%，芯材量0.40%，乳化剂量0.30%，该条件下平均粒径为219.40 nm，包埋率为71.80%。（2）分析红外谱图的特征峰及峰强度可知烟草香精被成功包埋；分析热重曲线图可知烟草香精亚微米微胶囊具有较好的热稳定性。（3）添加烟草香精亚微米微胶囊加热卷烟感官质量较对照明显提升，当添加量为10 mg/支时，感官评吸效果最好，可减轻刺激性，柔和烟气，提高香气质，增加香气量，减少逐口感官香气的差异性。（4）添加亚微米微胶囊的加热卷烟气溶胶中逐口香味物质总含量增加48.68%，数量增加6种，增加主要为L-薄荷醇、糠醇、茄酮等物质。
Abstract：To study the application effect of microencapsulated tobacco flavor in heated cigarettes, the complex coacervation method was used to prepare tobacco flavor submicron microcapsules. The preparation process was optimized, the physical and chemical properties were characterized, and the sensory effects of the submicron microcapsules in heated cigarettes, as well as the puff-by-puff release behavior in aerosol were studied. The results showed that(1) The optimum conditions for the preparation of tobacco submicron microcapsules by complex coacervation method were 0.18% chitosan, 0.40% core material, and 0.30% emulsifier dosage. Under this condition, the average particle size was 219.40 nm, and the encapsulation rate was 71.80%.(2) By analyzing the characteristic peak and peak intensity of the infrared spectrum, it was evident that the tobacco flavor was successfully entrapped. By analyzing the thermogravimetric curve, it showed that tobacco flavor submicron microcapsules had good thermal stability.(3) The sensory quality of heated cigarettes by adding tobacco flavor submicron microcapsules was significantly improved compared with the control. When the addition amount was 10 mg/cigarette, the sensory evaluation effect was the best, which could reduce the irritation, soften the smoke, improve the flavor quality, increase the aroma amount, and reduce the puff-by-puff difference of sensory aroma.(4) The total content of aroma components in the aerosol of heated cigarettes with submicron microcapsules increased by 48.68%, and the number increased by 6 kinds, mainly including L-menthol, furfuryl alcohol, solanone, among others.
