Research Progress on Preparation,Characterization and Structure-Activity Relationship of Feruloylated Arabinoxylan Oligosaccharides
In China,a large amount of cereal bran is produced as by-product of cereal processing each year,which is rich in phenolic acids and non-digestible polysaccharides.However,the added value of cereal bran is low due to its low utilization rate.In recent years,feruloylated arabinoxylan oligosaccharides(F-AXOs)have been prepared from cereal bran.F-AXOs are functional oligosaccharides which have been identified as having dual physiological activities of ferulic acid and oligosaccharide,such as antioxidant and probiotic properties,making F-AXOs have broad application prospects.This review summarizes the methods used for the preparation and characterization of F-AXOs from cereal bran and the current knowledge about their structures.Finally,this review focuses on the relationship between the structures and biological activities of F-AXOs and describes the application of F-AXOs in the food industry.This review is expected to provide theoretical guidance for the preparation and application of F-AXOs.
