In general, quinoa and amaranth dietary fibres are composed of
xyloglucans and pectic polysaccharides in varying amounts and
structures depending on the fibre fraction. Insoluble fibres from
pseudocereals were mainly composed of homogalacturonans
interspersed with RG-I stretches containing arabinan and galactan
side chains, xyloglucans mainly branched with di- and trisaccharide
side chains, and cellulose. The soluble fractions differed
slightly between quinoa and amaranth. Quinoa soluble fibre was
