^aTotal dietary fibre calculated as the sum of fructan and total dietary fibre analyzed by the Uppsala method.

^bExtractable dietary fibre calculated as the sum of fructan and extractable dietary fibre analyzed by the Uppsala method.

^cCalculated from arabinose, xylose and extractable galactose residue values assuming that the arabinose to galactose ratio is 0.69 in extractable arabinogalactan.

^dCellulose and resistant starch calculated as the difference between total β-glucan and the glucose residues analyzed by the Uppsala method.
