Beschreibung
Zusammenfassung:	This invention discloses carrier beads comprising a hydrocolloid polymer comprising at least one inert filler material, wherein the at least one filler material provides improved properties including increased mechanical strength and/or reduced porosity relative to a bead without said at least one filler. The beads are useful per se or for delivery of active agents. Methods for preparation of the beads and the uses thereof are described particularly for controlling the rate of release an active agent from said bead.
