Analysis of Monosaccharide Composition and Ferulic Acid Content in Corn Bran Subjected to Different Treatments

Abstract

Abstract: Refined corn bran (RCB) obtained by removing starch and protein was treated with acid or alkali to obtain acid hydrolysate (HAC) and alkaline hydrolysate (HAL). The monosaccharide composition and ferulic acid content of RCB, HAC and HAL were analyzed by HPLC. The results showed that the major components of HAC were feruloylated arabinoxylan, containing 44.5% of xylose, 20.8% of arabinose and 4.5% of ferulic acid. HAL was mainly arabinoxylan, containing of 50.3% xylose, 24.5% of arabinose and trace amount of ferulic acid. RCB contained 3.5% of ferulic acid.

Key words: refined corn bran, acid hydrolysate, alkaline hydrolysate, monosaccharide, ferulic acid
