摘要
壳聚糖无毒、无害,易于生物降解,不污染环境,是一种理想的微胶囊壁材。以壳聚糖为壁材,采用喷雾干燥工艺对香精进行微胶囊化,通过对乳液稳定性能的测定评价了大豆卵磷脂、蒸馏单甘酯和吐温6 0复配乳化剂的性能,系统的探讨了壁材浓度、乳化剂用量、芯壁比等对微胶囊化效果的影响,确定了最佳工艺条件;测试并分析了微囊的形貌、包埋率和释放率等质量指标。
Chitosan is an ideal microencapsulation material because it is a bio-degradable natural polymer without toxicity. Essence microcapsules were prepared by emulsification-spray drying method. The morphology and release properties of the microcapsules were tested. The influencing factors including concentrations of chitosan, emulsifier and loading essence were discussed and an optimal formula was proposed.
