Abstract:

The ferulic acid sugar esters prepared from wheat bran hydrolyzed by endo-xylanase were characterized for their antioxidant properties in vitro reflected by the abilities to scavenge hydrogen peroxide as well as hydroxyl and DPPH free radicals and to chelate metals using two synthetic antioxidants, BHT and VC, as the controls. The sugar esters were found to have strong antioxidant properties, which were better than those of free ferulic acid.

Key words: wheat bran, ferulic acid sugar esters, radicals, antioxidant properties
