Abstract: To compare the compression and consolidation behavior of some kinds of β-carotene powders with different compositions and different particle-forming technologies, their physical characteristics and the microstructure variation during the compression process were analyzedHeckel and Kawatika plots were constructed to reflect the powders compaction behavior, the consolidation mechanism of different powders were analyzed on the basis of these compaction parametersRegarding the β-carotene retention rate changes during the stability experiment, it was found that microcapsules with gelatin as wall material and formed with the starch-catch beadlet technology showed mainly plastic deformation instead of fragmentation and the core material β-carotene would be relatively stable, and these powders were suitable for tabletting..
