| 中文摘要: |
| 以β-环状糊精和阿拉伯胶为壁材，通过喷雾干燥法制备大鲵油微胶囊。通过单因素实验和正交实验研究进风口温度、进料速率、均质时间和均质转速对大鲵油微胶囊包埋率的影响，并研究微胶囊产品的理化性质。结果表明：大鲵油微胶囊制备的最佳工艺条件为进风口温度190?℃、进料速率3.5 mL/min、均质时间9 min和均质转速10 000 r/min，在此条件下大鲵油微胶囊包埋率达到94.73%。所得微胶囊水分含量为(305±0.04)%，休止角为(35.41±0.37)°，休止角在30°~45°之间，堆密度为0.28 g/cm3，粒径为5~10 μm，表面油和总油含量分别为0.58 g/100 g和11.07 g/100 g；微胶囊粉末黏度小，形状规则，表面光滑，流动性较好。表明所得大鲵油微胶囊品质良好。 |

| With β-cyclodextrin and arabia gum as wall material, Chinese giant salamander oil microcapsule was prepared by spray drying method. The effects of air inlet temperature, feeding rate, homogenization time and homogenization speed on the embedding rate of Chinese giant salamander oil microcapsule were studied by single factor experiment and orthogonal experiment, and the physicochemical properties of microcapsule were studied. The results showed that the optimal preparation conditions of Chinese giant salamander oil microcapsule were obtained as follows: air inlet temperature 190?℃, feeding rate 3.5 mL/min, homogenization time 9 min and homogenization speed 10 000 r/min. Under these conditions, the embedding rate of Chinese giant salamander oil microcapsule was 94.73%. The moisture content, repose angle, bulk density and particle size of microcapsule were (3.05±0.04)%, (35.41±037)°, 0.28 g/cm3 and 5-10 μm, respectively. The repose angle was between 30° and 45°. The contents of surface oil and total oil were 0.58 g/100 g and 11.07 g/100 g， respectively. The Chinese giant salamander oil microcapsule powder had lower viscosity, regular shape, smooth surface and good liquidity. The quality of the Chinese giant salamander oil microcapsule obtained was good. |
