The present invention relates to a method for producing rice bran oil from rice bran. Rice bran oil can be obtained by subjecting brown rice to refined rice (meaning rice milling, hereinafter referred to as osei and then subjecting rice bran generated when white rice is obtained to a suitable pretreatment and solvent extraction.
PURPOSE: To provide a method for preparing a rice bran edible oil whose physiological activity is strengthened. CONSTITUTION: In a process for purifying an edible oil such as a rice bran oil, non-saponified products and ferulic acid are recovered from edible oil- removed residues, concentrated and, if necessary, further esterified.
