A process for producing an unsaponifiable matters-enriched rice bran oil which comprises recovering unsaponifiable matters and ferulates from the residue obtained by collecting edible oil during the refining process of rice bran oil, concentrating the unsaponifiable matters and ferulates thus recovered, esterifying the same if desired, and adding the product obtained to edible rice bran oil, with the unsaponifiable matters-enriched edible rice bran oil thus obtained having improved qualities and exhibiting excellent physiological functions.
