Ferulic acid,one kind of phenolic acid, is mainly produced from oryzanol, a by-product of rice bran processing. It has many physiological functions, including antioxidation, antitumor and free radical scavenging. However, the poor solubility of ferulic acid in water and oil systems have limited its application. The physiological functions and preparation method of ferulic acid, as well as the research progress in high utilization value for hydrophilic and lipophilic derivatives of ferulic acid were reviewed, which could provide some available information for its synthesis and application, expand the application range of ferulic acid and improve the utilization value of rice bran. |
