The insoluble dietary fibre of the samples studied (Table
3) is characterized by its high content in glucose, followed
by galactose and arabinose, as well as important amounts
of uronic acids and xylose. The remaining monomers, mannose,
rhamnose and fucose, are present in smaller amounts.
From this composition it can be deduced that the insoluble
fibre comprises basically cellulose and hemicelluloses. In
the latter polysaccharides, the arabinogalactan are strongly
represented, as indicated by Hisamatsu, Fukumoto, Noda,
Teranishi, and Yamada (1995). AOAC plus hydrolysis
gives values slightly higher than the Englyst method, both
for the soybean seeds and the okara. On studying the
