摘　　要：采用微波辅助提取酸枣仁油,并以酸枣仁油为芯材,β-环糊精和大豆分离蛋白为壁材,喷雾干燥法制备酸枣仁油微胶囊。通过气相色谱-质谱(GC-MS)、傅里叶变换红外光谱(FTIR)、差示扫描量热仪(DSC)和扫描电镜(SEM)对酸枣仁油和微胶囊成分结构进行分析和表征,提取的酸枣仁油共检测出7种脂肪酸成分,不饱和脂肪酸含量为80.758%,其中单不饱和脂肪酸含量达56.375%,制备的微胶囊包埋率为67.54%。SEM显示,微胶囊颗粒形态完整;DSC分析表明,酸枣仁油微胶囊在常温下表现良好的热稳定性,可以满足食品的加工条件。The spine date seed oil microcapsules were prepared by spray drying method with microwave assisted extraction of spine date seed oil as the core material, β-cyclodextrin and soybean protein as the wall materials. The composition and structure of spine date seed oil and microcapsules were analyzed and characterized by gas chromatography-mass spectrometry(GCMS), Fourier transform infrared spectrum(FTIR), differential scanning calorimeter(DSC) and scanning electron microscope(SEM). Seven kinds of fatty acid components could be detected by microwave-assisted extraction of spine date seed oil. The content of unsaturated fatty acid was 80.758 %, and the amount of monounsaturated fatty acids came up to 56.375 %. The prepared microcapsule embedding rate was 67.54 %. SEM pictures showed that the microcapsule particles were intact in morphology. DSC analysis indicated thermal stability of the microcapsule product was better at room temperature, which could meet the food processing conditions.
