- •
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.
