Pentosans are polymers composed of pentoses. In contrast to cellulose, which is composed of hexose (glucose) monomers, pentosans are derived from five-carbon sugars such as xylose. Pentosan-rich biomass is the precursor to furfural.
The pentosan content has been determined for many natural materials:
- 29-25%: oat hulls, cottonseed hulls, barley,sugarcane bagasse, sunflower husks
- 24-20% wheat straw, flax shives, hazelnut shells, birchwood, eucalyptus wood
- 8% pinewood
- 3% peanut shells
Pentosans can act as heparinoids, glycosaminoglycans which are derivatives of heparin.
They can have an influence on bread quality.
