摘　　要：采用复相乳液法,研制了以乙基纤维素为壁材,以碳酸钠为芯材的微胶囊化产品.结果表明:微胶囊化的最佳工艺参数为壁材溶液浓度为8%,保护剂溶液浓度为10%,搅拌速度为600 r/min,油相∶水相为1∶6.以乙基纤维素作为壁材制得的微胶囊化碳酸钠具有较高的产率.Microencapsulation of sodium bicarbonate was prepared by multiple emulsion-solvent evaporation method in which ethyl cellulose was as the wall materials. The results showed that the optimal technology parameters of microencapsulated sodium bicarbonate were as follows： stirring speed 600 r/min, wall-material concentration 8% , protective agent concentration 10% , the ratio of oil to water 1：6. Microencapsulated sodium bicarbonate with ethyl cellulose as the wall material has a relatively higher yield.
