主 题：β-carotene microcapsule powders flowability Hausner ratio repose angle
摘 要：The flowability of five kinds of microencapsulation powders,with differentβ-carotene contents and by two alternative particle-forming technologies ***-drying and starch-catching beadlet technology,was meas- *** actual flow properties of the five powders were compared based on bin-flow test,and three flow indexes (Hausner ratio,repose angle and flow index)were *** was found that the repose angle is the most suitable index to reflect the flowability of these powders for the particle properties would not be altered due to compaction or tapping during the measuring *** size and particle size distribution play most important roles in the flowability of these granular materials,which was also influenced by other factors like shape,surface texture,sur- face roughness,*** with wall material of gelatin and a layer of modified starch absorbed on the sur- face showed excellent flowabilities and good mechanical properties,and they are favorable for tabletting to supply β-carotene.
