The present invention provides a reduced-cost production method for an acidic xylooligosaccharide, the production method including a step for depolymerizing a plant-derived starting material. The depolymerization step is preferably a heat treatment step, and the average degree of polymerization or the molecular weight of the acidic xylooligosaccharide that is produced can be controlled by regulating P as expressed in the formula, in which T represents absolute temperature, and t represents heat treatment time. |
