Abstract: The technology of by complex coacervation method to prepare coacervates,and the coacervates dried to prepare Vitamin A microcapsules by spray drying was investigated. Single factor and orthogonal test were done and evaluating indicator is encapsulation efficiency. The following optimum processing conditions for preparing vitamin A microcapsules were obtained: pH 4.2,impeller rotational time 20min,the ratio of core material to wall material 3:1,temperature 45℃.

Key words: vitamin A, microcapsule, complex coacervation, spray drying, encapsulation efficiency
