Abstract:
The emulsification-internal gelatin method is used to formulate alginate gels and alginate-chitosan microcapsules;Diffusion properties of the alginate gels and alginate-chitosan microcapsules also were investigated with spectrophotometry by the permeability to VitaminB12.The swellability of the alginate gels and alginate-chitosan microcapsules also were investigated,and the influence of the swellability on permeability also was investigated.The results show that the permeability and swellability of alginate-chitosan microcapsules was lower than alginate gels.
