摘要
研究采用明胶-海藻酸钠复合制备烟用茶树花精油缓释剂,复合型缓释材料明胶与海藻酸钠复合物表现出良好的性能,能够与所选定的茶树花精油复合;对缓释材料最佳工艺条件的研究表明:缓释材料明胶和海藻酸钠复合物中,明胶和海藻酸钠的比例对茶树花精油微胶囊的包埋效率影响最大,其次是茶树花精油与缓释剂质量比,喷雾干燥法进风口的温度对茶树花精油微胶囊的包埋效率的影响最小,得到的最佳工艺条件为明胶和海藻酸钠的比例为20∶80,茶树花精油与缓释剂质量比为1∶8,固形物的含量为40%,喷雾干燥法进风口的温度为180℃。在卷烟中的初步应用研究结果显示:添加茶树花精油微胶囊后,能显卷烟的香气量和香气质略有增加,茶香香韵增加明显。
Gelatin-sodium alginate compound was used to prepare controlled-release material for essential oils from tea flower in these research. Result shows a good match of microencapsnlation substance and a good performance of the controlled- release material of gelatin-sodium alginate, which can well combine with essential oils. Optimization research shows that the quantity ration between gelatin and sodium alginate has the biggest influence on the microencapsulation efficiency of characteristic flavoring substance, following by the quantity ration between essential oils and controlled-release material, while the air inlet temperature of spray drying has the minimal influence on the microencapsulation efficiency. The optimization conditions obtained are： proportion between gelatin and sodium alginate： 20 ： 80; the quantity ratio between essential oils and the controlled-release material： 1 ： 8; the solids content： 40%; the air inlet temperature of spray drying： 180 ℃. The findings in cigarette show that it＇s the best effect when the microencapsulation of the tea flower essential oil is added to the cigarette.
