Abstract:

Gastro-resistant complex microcapsules were prepared with freeze-dried powder of immune colostrum fermentedwith Bifidobacterium adolescentis as core material by air suspension technique. Opadry was determined as the optimal wallmaterial based on film-forming property, spraying capacity, dissolution rate, enteric solubility, acid resistance and storagestability. The optimal coating concentration and mass ratio of core to wall material were 15% and 10:3, respectively, whenspraying capacity and microcapsule performance were taken into account.

Key words: Bifidobacterium adolescentis, IgG, microcapsule, capsule wall
