The process for producing a jellylike drink of the present invention comprises a mixing step of mixinga powdery gelling agent with a powdery sweetening agent (I) to obtain a mixed powder and a dissolving step (I) of dissolving the resulting mixed powder in water at not higher than 80°C. According to this process, special production facilities to maintain the system at a high temperature exceeding 80°C are unnecessary, lumps are not formed, and enhancement of production efficiency is feasible. Moreover, because the system is not maintained at a high temperature exceeding 80°C when the gelling agent is dissolved, decomposition reaction of the gelling agent is inhibited, and the water release ratio after the lapse of time is low, so that stable appearance and performance of the product can be kept over a long period of time.
