Abstract :In this study, a series of gelatin and chitosan hydrogel beads were prepared via covalently crosslinking of these polymers. At the first step, three types of gelatin beads were obtained by dropping polymer solution into Glutaraldehyde insert ignore into journalissuearticles values(GA);-oil emulsion. While the concentration of polymer solution was varied from 7% to 14%, the concentration of crosslinking solution kept constant. Secondly, two types of chitosan beads were prepared by ionic gelation interaction procedure using Sodium Tripolyphosphate insert ignore into journalissuearticles values(TPP); as crosslinker. 1% of polymer solution was dropped into TPP solutions at different concentrations. At the last step, the different series of gelatin hydrogels were prepared by cutting the crosslinked polymer roads to form beads.  Swelling behaviors of all the hydrogel beads were studied by changing time at constant temperature and pH. Swelling percentages insert ignore into journalissuearticles values(S%); increased with time initially, and then remained constant at close to 24 h. In general, it was determined that the gelatin hydrogel beads were much more swellable than the chitosan beads.
