Abstract The objective of this work was to investigate the feasibility of inducing complex coacervation by atomizing an emulsion of gelatin/ginger oil over a gum Arabic solution, which would be a first step towards continuous process configuration. The influence of gelatin:gum Arabic ratio was investigated regarding capsule formation by atomization. In addition, the effects of emulsion concentration on coacervation by atomization and by batch stirring were studied. Gelatin:gum Arabic ratio strongly affected the capsule formation. The gelatin concentration affected the size of capsules for both methods, whereas the increase of gelatin concentration did not affect encapsulation parameters for atomized capsules. The diameter of microcapsules varied from 57 to 85 μm, encapsulation efficiency varied between 89.74 and 98.7%, and encapsulation yield ranged from 21 to 88%, with the atomization process resulting in higher encapsulation yield. The results indicated that microcapsules produced by atomization were comparable with capsules produced by batch stirring.

雾化复合凝聚法微囊化姜油：聚合物比例和壁材浓度的影响

摘要 这项工作的目的是研究通过在阿拉伯树胶溶液上雾化明胶/姜油乳液来诱导复合凝聚的可行性，这将是实现连续工艺配置的第一步。研究了明胶：阿拉伯树胶比率对雾化胶囊形成的影响。此外，研究了乳液浓度对雾化和间歇搅拌凝聚的影响。明胶：阿拉伯树胶比率强烈影响胶囊形成。明胶浓度影响两种方法的胶囊大小，而明胶浓度的增加不影响雾化胶囊的封装参数。微胶囊的直径从57到85微米不等，包封效率在89.74%到98.7%之间，包封率在 21% 到 88% 之间，雾化过程导致包封率更高。结果表明，雾化生产的微胶囊与间歇搅拌生产的胶囊相当。
