| 摘 要： | 为制备含玉米低聚肽的紫苏籽油微胶囊，选择阿拉伯胶、可溶性大豆多糖、辛烯基琥珀酸淀粉钠（HI-CAP 100）、酪蛋白酸钠和大豆分离蛋白5 种乳化剂，并添加不同质量分数的玉米低聚肽制备紫苏籽油乳状液，筛选出制备紫苏籽油乳状液的最适乳化剂及最佳的玉米低聚肽添加比例；进而采用喷雾干燥法制备高载油量的玉米低聚肽紫苏籽油微胶囊，筛选和评价高载油量玉米低聚肽紫苏籽油微胶囊的壁材。结果显示：HI-CAP 100制备的紫苏籽油乳状液的液滴粒径主要分布在0.1～2 μm之间，并且玉米低聚肽添加量为5%时，乳状液的不稳定性指数为0.275，粒径为（0.76±0.02）μm；以HI-CAP 100为壁材经喷雾干燥制成的目标微胶囊（载油量≥50%）表面油含量为3%，表明HI-CAP 100对紫苏籽油的包埋效果较好，并且微胶囊粒径分布均匀，表面较光滑适合作为高载油量玉米低聚肽紫苏籽油微胶囊的壁材；通过加速贮藏实验证明玉米低聚肽与茶多酚棕榈酸酯复配，能提高紫苏籽油微胶囊的抗氧化性。

| Abstract: | In this study, five different emulsifiers, gum arabic, soluble soybean polysaccharide, starch sodium octenylsuccinate(HI-CAP 100), sodium caseinate and soybean protein isolate(SPI) were separately used to prepare perilla seed oil emulsions with the addition of different concentrations of corn oligopeptide. We selected the optimal emulsifier and corn oligopeptide concentration for further preparation of microcapsules with high oil loading by spray drying. We chose and evaluated the optimal wall material for maximum oil loading. The results showed that the droplet size of perilla seed oil emulsion prepared using HI-CAP 100 as the emulsifier was mainly distributed between 0.1 and 2 μm;upon the addition of 5% corn oligopeptide, the particle size was small, only(0.76 ± 0.02) μm, and the instability index was 0.275. The surface oil percentage of the microcapsule prepared using HI-CAP 100(with oil loading ≥ 50%) as the wall material was 3%, indicating good microencapsulation efficiency, and the microcapsule exhibited uniform particle size distribution and smooth surfaces. Accelerated storage tests proved that combination of corn oligopeptide and tea polyphenol palmitate could effectively improve the antioxidant capacity of perilla seed oil microcapsules. |
