Abstract: The basic characteries of alginate/BSA microcapsule processed in high-voltage electrostatic field have been studied.The results showed: BSA was in the crystal form inside the microcapsule ; the ratio of ingredients, added the concentration ofchitosan and the pH of CaCl2 could directly affect the encapsulation efficiency and the core material loading ; and chitosan mightimprove release in vitro considerably. In addition, different drying methods could also influence release performance.

Key words: high-voltage electrostatic field, microcapsule, protein
