Relationships between the AX structure, AX solubility of and dynamic viscosity of laboratory scale samples of wholemeal (WM, coloured black), wet distillers grains (WDG, coloured green) and DDGS (D, coloured blue). (A) dynamic viscosity vs. percentage arabinosylation; (B) dynamic viscosity vs. amount of WE-AX; (C) dynamic viscosity vs. percentage of XA3A3XX; (D) percentage of arabinosylation vs. amount of WE-AX.
