Abstract: Sodium hydroxide was used to release ferulic acid from wheat bron. The optimal technology was to extract defattedand deproteined wheat bran at 85℃ for 6 h with 0.5% concentration of sodium hydroxide, to release ferulic acid 277.2 mg/100g bran, Addition of sodium sulfite to the extraction solution increased the recovery rate of ferulic acid to 308.7mg/100gbran.Atter the removal of ferulic acid wheat bran was much more easily hydrolyzed by hydrochloric acid and polysaccha-rides hydrolyzing enzymes secreted by Aspergillus niger.This fact suggested that the bran residue could be used to produceoliosaccharides.

Key words: Wheat bran , Ferulic acid , Oligosaccharides
