The values represent the average ± standard deviation. Values in the same row with the same lower-case letter showed no significant difference (p < 0.05). ‘avDP’ and ‘avDS’ represent the average degree of polymerisation of water extractable arabinoxylans (WE-AX) and the average degree of arabinose substitution, respectively. Total AX refers to the total arabinoxylan content in the sample of which in % water extractable arabinoxylan are illustrated in row 3. The richness of WE-AX is related to the total arabinoxylan content of the individual sample
