| 摘要:为解决卷烟赋香过程中香精易挥发、留香期短的技术难题，提升卷烟感官品质与稳定性，本研究以烟草香精（TE）为芯材，以明胶（GE）和烟草纳米纤维素（JCNF）为壁材，通过复凝聚法制备GE/JCNF@TE微胶囊。通过单因素实验考察壁材浓度、壁材比、芯壁比对微胶囊粒径和包埋率的影响，确定最优制备条件为壁材浓度2.0% (w/v)，壁材质量比6∶1，芯壁质量比1∶1。在最优条件下制备的GE/JCNF@TE微胶囊香精包埋率最高（63%），Zeta电位为-23.12 mV，平均粒径为(1.23±0.05) μm，且具有良好的热稳定性。此外，GE/JCNF@TE微胶囊具有良好的pH稳定性和缓释性能，在28天烟草香精的释放率为55%，展现出平稳、持久的释放行为，烟草香精保留率显著高于单壁微胶囊。 |
| Abstract:To solve the technical problems of easy volatilization and short fragrance retention period of flavor during cigarette flavoring, and to improve the sensory quality and stability of cigarettes, this study used tobacco essence (TE) as the core material, gelatin (GE) and tobacco nanocellulose (JCNF) as the wall materials, and prepared GE/JCNF@TE microcapsules by the complex coacervation method. The optimal preparation conditions were determined by investigating the effects of wall material concentration, wall material ratio, and core-to-wall ratio on the particle size and encapsulation efficiency of the microcapsules through single-factor experiments: wall material concentration of 2.0% (w/v), wall material ratio of 6∶1, and core-to-wall ratio of 1∶1. The microcapsules prepared under the optimal conditions exhibited the highest encapsulation efficiency (63%), with a Zeta potential of -23.12 mV and an average particle size of (1.23±0.05) μm, as well as excellent thermal stability. In addition, the GE/JCNF@TE microcapsules showed good pH stability and sustained-release performance. During the 28-day release test, the release rate was 55%, demonstrating a steady and prolonged release behavior, with the tobacco essence retention rate being significantly higher than that of single-wall microcapsules. |
