Disclosed is a method of manufacturing a fluid gel, the method comprising adding metal cations to the gellant dispersion while retaining the pH at no greater than 3 and adding a pH modifying agent to the gellant dispersion to increase the pH of the gellant dispersion to greater than 3.本發明揭示一種製造流體凝膠之方法,方法包括添加金屬陽離子於膠凝劑分散液,同時保持pH不大於3;及添加pH改質劑於膠凝劑分散液,以增加膠凝劑分散液之pH至大於3。
