摘　　要：为提高姜风味成分的稳定性,以麦芽糊精、阿拉伯胶、β-环糊精为壁材采用喷雾干燥法制备姜风味微胶囊。以包埋率为评价指标优化制备工艺,并对微胶囊颗粒理化性质、微观形态及稳定性进行分析。结果表明,微胶囊的最佳制备工艺:进口温度160℃、喷雾空气柱45 mm及芯壁质量比1:5。此条件下微胶囊包埋率可达81.32%,呈现完整球形结构,粒径约为15~20μm,其含水量为2.54%,溶解度为95.5%,休止角为42.18°。GC-MS分析表明,贮藏期间姜风味微胶囊比普通姜粉的风味成分更稳定。因此,最佳条件下制备的微胶囊具有良好的流动性、溶解性且风味稳定性较高,可满足一般食品加工条件,为生姜调味产品的研发与改进提供参考。To improve the stability of ginger flavor components,ginger flavor microcapsules were prepared by spray drying with maltodextrin,gum arabic,andβ-cyclodextrin as wall materials.The preparation process was optimized with the embedding rate as an evaluation index,and the physical and chemical properties,micromorphology and stability of microcapsules were analyzed.Results showed that the optimal preparation process of microcapsules was as follows:inlet temperature of 160℃,spray air column of 45 mm,and core-to-wall mass ratio of 1:5.Under these conditions,the embedding rate of microcapsules could reach 81.32%,showing a complete spherical structure with a particle size of about 15-20μm,water content of 2.54%,solubility of 95.5%,and angle of repose of 42.18°.GC-MS analysis showed that the flavor components of ginger flavor microcapsules were more stable than those of ordinary ginger powder after storage.Therefore,the microcapsules prepared under the best conditions have good fluidity,solubility and flavor stability,which can meet the general food processing conditions.The microcapsules provide a reference for the development and improvement of ginger seasoning products.
