Abstract
The present invention concerns an improved process for biorefinery of brown macroalgae, which comprises: (a) contacting the brown macroalgae with a solvent system comprising at least 30 wt % organic solvent, to obtain extracted macroalgae as solid residue and a liquor; and (b) biorefining the extracted macroalgae. The inventors have found that the contacting of step (a) results in an efficient and cost-effective dewatering of the macroalgae, wherein up to 95 wt % of the internal moisture of the macroalgae could be lost without the need for energy-consuming drying techniques. As such, the downstream biorefinery of the extracted macroalgae is greatly facilitated.
Claims20
A process for biorefining brown macroalgae, comprising:
- (a) contacting the brown macroalgae with a solvent system comprising at least 30 wt % of a ketone organic solvent, wherein water is expelled from the macroalgae, to obtain extracted macroalgae as solid residue and a liquor comprising expelled water;
- (b) biorefining the extracted macroalgae;
- and
- (c) isolating mannitol from the liquor by separation of the organic solvent and water.
