It was investigated whether methylcellulose microcapsules containing 1-giutamine were able to be prepared by using coalescence between two kinds of droplets in W/O emulsion or not. Methylcellulose as the shell material was dissolved in the one aqueous droplets and the tannic acid as the gelation agent for methylcellulose was dissolved in the other aqueous droplets. It was found that methylcellulose microcapsules were able to be prepared by coalescence between the two kinds of droplets. The mean microcapsule diameter and the content rate of 1-glutamine were found to increase with the concentration of methylcellulose. Moreover, it was found that microcapsules were not destroyed in the water phase and 1-glutamine was released through the ungelated part of the microcapsule shell.
