The present invention addresses the problem of providing a method for efficiently producing uniform microparticles of curcumin and/or γ-oryzanol at a higher yield. The target microparticles are produced by dissolving a starting material in a solvent to give a starting material solution and then subjecting the starting material solution to crystallization by a poor solvent method to thereby deposit the starting material. To prepare the starting material solution, curcumin and/or γ-oryzanol are used as the starting material(s) and ethanol is used as the solvent. The starting material(s) and the solvent are stirred in a pressurized state at a temperature of 78.3-130°C inclusive to give the starting material solution. Then, the starting material solution thus obtained is subjected to crystallization by the poor solvent method and thus the target microparticles are produced.
