摘　　要：试验旨在探究制备松针挥发油微囊的最优工艺。以阿拉伯胶和明胶为壁材,采用复凝聚法制备松针挥发油微囊,单因素试验考察了阿拉伯胶和明胶的比例、芯壁比、成囊温度和复凝聚反应时间对微囊的形成的影响;以微囊的包埋率、载药率和产率的综合评分为评估标准,通过正交试验筛选出松针挥发油微囊的最优条件。结果显示,明胶与阿拉伯胶的比例为1.0∶1.0、芯材与壁材比为1.0∶2.0、成囊温度为35℃时,制备出的松针挥发油微囊的包埋率和综合评分均最高,分别为82.98%和68.92。且微囊表面光滑、形态规则、不粘连、粒径大小均一。研究表明,试验使用复凝聚法制备微囊化效率高,可为挥发油在饲料添加剂领域的应用提供参考。The aim of this experiment was to identify the optimal process for preparing microcapsules of Pinus massoniana needles volatile oil.Using gum arabic and gelatin as wall materials,the microcapsules were prepared using the coacervation method.Single-factor experiments were conducted to investigate the effects of the ratio of gum arabic to gelatin,the core-to-wall ratio,the coacervation temperature,and the coacervation reaction time on the formation of the microcapsules.The encapsulation efficiency,drug loading,and yield were used as the criteria for evaluating the microcapsules,and the optimal conditions for Pinus massoniana needles volatile oil microcapsules were selected through orthogonal experiments.The results showed that when the ratio of gelatin to gum arabic was 1.0∶1.0,the core-to-wall ratio was 1.0∶2.0,and the coacervation temperature was 35℃,the encapsulation efficiency and comprehensive score of the Pinus massoniana needles volatile oil microcapsules were the highest,at 82.98%and 68.92,respectively.The microcapsules had a smooth surface,regular shape,non-adhesive properties,and uniform particle size.The study indicates that the coacervation method used in the experiment is efficient for preparing microencapsulation and can provide a reference for the application of volatile oils in the field of feed additives.
