PURPOSE: To enable efficient production of ferulic acid which is useful as a starting material for medicines, agrochemicals, cosmetics, pigments or foods by utilizing the waste products or by-products in the production of rice salad oil (rice bran oil) and rice fatty acids from rice bran.
CONSTITUTION: The waste product and/or by-products obtained in the production of rice salad oil and rice fatty acids from the starting substance containing α-oryzanol, preferably rice bran, for example, alkali oil lees or fatty acids are alkali-hydrolyzed to give a solution containing alkali salts of ferulic acid of about 70 to 90wt.% purity. Then, the solution is acidified to precipitate free ferulic acid, which is separated by filtration. The collected ferulic acid is dissolved in hot water (at about 90 to 100°C), then the solution is cooled down to crystallize out pure ferulic acid of the trans-form.
