摘要: 通过对高压静电场制备的海藻酸盐/BSA蛋白类物质微胶囊基本性质的研究,结果表明,BSA在微胶囊中仍以晶体的形式存在;配料比、壳聚糖浓度、CaCl2溶液的pH对包封率和芯材载入率有直接的影响;壳聚糖能显著改善微胶囊的体外释放性能,同时,干燥方式的不同,也会对释放性能产生一定的影响。

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.
