PROBLEM TO BE SOLVED: To provide a production method of a gelatinous food product holding hydrogen gas bubbles each having a visible size； and to provide a gelatinous food product obtained by the production method.SOLUTION: A gelator is added into aqueous solution having a raised temperature, and agitated to be cooled, and to heighten a viscosity of the aqueous solution. When the viscosity is heightened to a degree just before gelation, hydrogen gas bubbles each having a visible size are supplied into the aqueous solution, and when rise of hydrogen gas bubbles is stopped by visual observation caused by more viscosity increase by cooling, supply of the hydrogen gas bubbles is stopped.SELECTED DRAWING: Figure 2【課題】 視認できる大きさの水素ガス気泡が保持されたゲル状食品の製造方法とこの製造方法によって得られるゲル状食品を提供する。【解決手段】 昇温した水溶液（水を含む）にゲル化剤を添加して攪拌しつつ冷却することで水溶液の粘度を高め、ゲル化直前まで粘度が高まった時点で前記水溶液へ視認できる大きさの水素ガス気泡の供給を行い、冷却による更なる粘度上昇で目視による水素ガス気泡の上昇が停止した時点で水素ガス気泡の供給を停止する。【選択図】 図２
