摘要
为探究大黄鱼鱼卵磷脂/麦芽糊精包埋虾青素微胶囊性质,采用喷雾干燥技术制备了大黄鱼鱼卵磷脂/麦芽糊精-虾青素微胶囊,通过测定微胶囊的水分含量、过氧化值、酸价、虾青素包埋率及溶解度等指标,结合场发射扫描电子显微镜、傅里叶红外光谱、热稳定性分析考察了微胶囊的理化性质并进行体外模拟消化研究。结果表明,大黄鱼鱼卵磷脂/麦芽糊精-虾青素微胶囊包埋率高达(90.12±2.01)%,外观呈近球状,表面致密,无明显裂纹,大黄鱼鱼卵磷脂/麦芽糊精-虾青素可形成稳定的微胶囊,并能够在体外模拟消化液中实现缓慢释放。研究结果可为开发大黄鱼鱼卵磷脂作为微胶囊新型壁材提供理论依据。
This study aimed to investigate the physicochemical properties of astaxanthin embedded with large yellow croaker roe phospholipids(LYCRPLs)/maltodextrin(MD)microcapsules.LYCRPLs/MD-astaxanthin(AST)microcapsules were prepared by spray drying technology with AST as core material.The properties of microcapsules were characterized by measuring the water content,peroxide value,acid value,astaxanthin embedding rate,and solubility,combined with field emission scanning electron microscopy,Fourier transform infrared spectroscopy,and thermogravimetric analysis.The sustained-release properties of microcapsules during in vitro digestion were also analyzed.Results showed that the encapsulation efficiency of lecithin/maltodextrin as wall material was as high as(90.12±2.01)%,and the microcapsules were nearly spherical,with compact surface and no obvious cracks.The LYCRPLs/MD and AST could form a stable microcapsule system.In vitro simulated digestion experiments showed that microcapsules could be released slowly in simulated gastric and intestinal fluid.The results provide a theoretical basis for the application of LYCRPLs as a new microcapsules wall material.
