Research Progress on Distribution, Forms and Preparation Methods of Ferulic Acid in Wheat

Ferulic acid is a beneficial human health phenolic acid that reduces the risk of serious diseases such as diabetes, cholesterol, heart disease and cancer. Ferulic acid is the highest content phenolic acid in wheat, mainly concentrated in wheat bran. With the improvement of people’s awareness of health care, the preparation and function of ferulic acid in wheat bran have been paid more and more attention. The methods of preparing ferulic acid from wheat bran generally include alkaline hydrolysis, biological enzyme and biological fermentation, and many studies have assisted the above preparation methods by physical means, such as ultrasonic and high temperature steam, etc. In this paper, the distribution and form of ferulic acid in wheat and the method of preparing ferulic acid from wheat bran are summarized, and the advantages and disadvantages of the method of preparing ferulic acid from wheat bran are analyzed, so as to provide some references and ideas for the development, research and industrial production of ferulic acid in wheat bran.
