PURPOSE:To provide the subject inhibitor containing an organic solvent-soluble material of fermented rice as the active component, useful for prevention of a spot or a freckle due to sunburn, capable of production from inexpensive recedily available raw materials and excellent in safety. CONSTITUTION:The objective inhibitor contains an organic solvent-soluble material of fermented rice as the active component preferably in an amount of >=0.0001wt.%. In addition, rice wine lees obtained as a by-product in production of refined rice wine is used as the raw material fermented rice in general. The organic solvent-soluble material of fermented rice is obtained, e.g. by dispersing rice wine lees in ethanol, homogenizing it using a homomixer, carrying out centrifugal separation, then evaporating ethanol from the resultant supernatant under a reduced pressure and subsequently further adding ethanol thereto. |
