These microparticles include: alginate and alginate CMC microcapsules prepared by emulsion coacervation process (ECP), alginate and gelatin microcapsules prepared by spray drying process (SDP), and alginate microbound. The results show these five microparticulate forms of VB 1 can reduce leaching significantly compared to crystalline form VB 1, and the leaching rates at different intervals, diameters and encapsulation efficiencies ( EE ) are significantly different among all kinds of microparticles (ANOVA, P <0.05). The leaching properties of the five microparticles are in accord with Higuchi equation. Based on the regression equation, the half loss time ( T 50 ) is determined.In conclusion, the alginate CMC microencapsule is a potential tool to reduce leaching of water soluble vitamins.展开更多
