摘　　要：以双歧杆菌发酵免疫初乳,采用真空冷冻干燥技术研制成冻干粉,并以冻干粉为芯材、以不同肠溶材料作为壁材,采用空气悬浮微胶囊化的方法制成免疫与微生态双活性肠溶制剂。从不同壁材的成膜性、喷雾性、溶出度、肠溶性、耐酸性、贮存稳定性等方面确定以欧巴代作为微胶囊的壁材,从喷雾性能及微胶囊的性能考虑,包衣液的质量分数为15%,芯材、壁材质量比为10∶3。Gastro-resistant complex microcapsules were prepared with freeze-dried powder of immune colostrum fermented with Bifutobacterium adolescentis as core material by air suspension technique.Opadry was determined as the optimal wall material based on film-forming property,spraying capacity,dissolution rate,enteric solubility,acid resistance and storage stability.The optimal coating concentration and mass ratio of core to wall material were 15％ and 10∶3,respectively,when spraying capacity and microcapsule performance were taken into account.
