The rye bran consisted of 25.6% AX, 4.2% β-glucans and a total DF
content of 36%. The oat bran consisted of 5.2% AX, 10.2% β-glucans
(3.3% soluble β-glucans) and a total DF content of 18.4%. The barley
fibre used in this study had an AX content of 20.8% and a total DF
content of 63.2%. It had a total β-glucan content of 32%, including a
very high proportion of soluble β-glucans, 22.3%. Most of the AX were
insoluble: 91% of the rye bran AX, 98% of the oat bran AX and 89%
of the barley fibre AX.
