  Watersoluble components of Pinus pinaster wood ...

  Abstract. Aqueous fractionation of wood has been proposed as a suitable processing method for biorefineries. When treatments are performed under low severity conditions, watersoluble components (which could be detrimental in further processing stages) are removed, whereas polysaccharides, lignin, and other waterinsoluble constituents remain in solid phase with little alteration.
