PROBLEM TO BE SOLVED: To provide a method for relatively easily producing a gel composition containing the decomposed product of the galactose part in galactoxyloglucan, and a gel composition produced by the production method.SOLUTION: Provided is a method for producing a gel composition provided with the following steps (1) to (3): (1) a step where the decomposed product of the galactose part in galactoxyloglucan and a water based solvent are mixed at a room temperature (2) a step where the mixture obtained in the step (1) is cooled or frozen and (3) a step where the mixture cooled or frozen in the step (2) is heated so as to be gelled to obtain a gel composition containing the decomposed product of the galactose part.SELECTED DRAWING: None
