摘　　要：为扩大八角油树脂在食品中的应用,采用喷雾干燥法研究了八角油树脂微胶囊工艺,通过单因素实验和正交实验确定适宜的壁材组合为阿拉伯胶:麦芽糊精的质量比为3:7,壁芯的质量比为1:6.胶液浓度为30%。在40℃、50 MPa条件下均质2次。喷雾干燥参数:蠕动泵转速20 r/min、进风温度140℃、出风温度70℃时包埋率可达92%。To expand the application of aniseed oleoresin in foods the preparation technology of aniseed oleoresin micmcapsules by spray drying was studied. The optimum parameters obtained through single factorial and orthogonal experiments are as follows： the wall material being composed of arabic gmn and malt dextrine at a ratio of 3 to 7, the rate of wall material to core material being at 1 to 6, liquid concentration being 30 % ; twice homogenization at 50 Mpa and 40 ℃. The optimum spray drying conditions are wriggle pump speed 20 r/min, enter temperature 140 ℃ and outlet temperature 70 ℃. The degree of encapsulation is as high as 92 %.
