摘要

•In Brewers’ spent grain (BSG) arabinose did not justify all branches present in xylan.•Mass spectrometry (MS) analysis assigned other substituents than arabinose on xylan.•MS analysis revealed also hexose residues attached to arabinoxylans.•BSG presents glucuronoarabinoxylans and acetylated arabinoxylans.•The BSG is a potential source of a large screening prebiotic by-product.
