Pentosan

Polysaccharide

Polysaccharide

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.
