Abstract:
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.

Claim (Index 3):
The method for producing microparticles from a pressurized and heated raw material solution according to  claim 1 ,\n wherein when a concentration of curcumin in the raw material solution is taken as x (% by weight), a temperature of an ethanol solution of curcumin to be used in the crystallization operation by means of the poor solvent method is made to a temperature y (\u00b0 C.) which is indicated by a formula (1) thereby producing curcumin microparticles\n y\u2265 0.0222 x 3 \u22122.7 x 2 +30.511 x\u2212 12.833\u2003\u2003(1).
