- The content of minerals and dietary fibre in different fractions of oats was investigated. The oat kernel (pericarp, testa, germ, aleurone, endosperm), accounting for 70 % of the oat seed, had a dietary fibre content of 11·5 g/100 g (dry weight basis); of this 23 % was soluble fibre components, mainly β-glucans. In contrast to most other cereals the amount of soluble fibre was distributed throughout the whole kernel. The oat husk, accounting for the remaining 30 %, has a considerably higher dietary fibre content than the kernel, 83·9 g/100 g. Most of the fibre in the husk (~ 99 %) was insoluble polymers containing cellulose and considerable amounts of xylans and lignin. The minerals associated with the fibre complex in the husk were mostly (~ 97 %) present in the insoluble fibre fraction (50 % of the Si and 30 % of the K). On the other hand, most (~ 70%) of the minerals in the kernel, were associated with the soluble fibre components (〉 50% of the Ca, Fe, Mn and P), probably the β-glucans and/or the phytic acid. Fe and Cu were the only minerals that were found to any greater extent in the insoluble fibre fraction in the kernel (~ 20%). Most of the phytate (〉 90%) was found in the soluble fibre fraction.
