doi:10.15933/j.cnki.1004-3268.2022.06.019

Abstract

Abstract: In order to study the preparation technology of cinnamyl alcohol microcapsules and their application effect in cigarette，the cinnamyl alcohol microcapsules were prepared by spray drying with sodium alginate extracted from kelp and gelatin as composite wall materials and cinnamyl alcohol as core material and added into cigarette products.The content of cinnamyl alcohol and the embedding rate of prepared cinnamyl alcohol microcapsules were 27.2% and 82.1%，and the average particle size was 8.1 μm.The structure of cinnamyl alcohol microcapsules was characterized by Fourier transform infrared spectroscopy.The results showed that cinnamyl alcohol was effectively embedded in the microcapsules.The addition of cinnamyl alcohol microcapsules（50 mg/stick）in cigarette filter rod could enhance the aroma of cigarettes，improve the smoothness and softness of smoke，and increase the moist feeling.The puff⁃by⁃puff release of cinnamyl alcohol microcapsules was uniform and stable.After 60 days of storage，the content of cinnamyl alcohol in total smoke of cigarettes decreased slowly from 2.34 μg/stick to 2.08 μg/stick，and the storage stability was improved.

摘要： 为研究肉桂醇微胶囊的制备工艺及其在卷烟中的应用效果，以海带中提取的海藻酸钠和明胶为复合壁材、肉桂醇为芯材，采用喷雾干燥法制备肉桂醇微胶囊，并添加于卷烟制品中。制备的肉桂醇微胶囊样品中，肉桂醇含量为27.2%，包埋率为82.1%，平均粒径为8.1 μm。通过傅里叶红外光谱仪对肉桂醇微胶囊进行结构表征，发现肉桂醇能有效包埋于微胶囊中。将肉桂醇微胶囊添加于卷烟滤棒中进行感观评价，结果显示，最适宜的肉桂醇微胶囊添加量为50 mg/支，具有增强卷烟香韵，改善烟气的细腻、柔和度，增加润感的作用，且逐口释放均匀稳定；放置60 d时，抽吸过程总烟气中肉桂醇含量从初始的2.34 μg/支缓慢下降到2.08 μg/支，贮存的稳定性明显提高。
