Title (EN) IMPROVED BIOREFINERY OF BROWN MACROALGAE
(FR) BIOAFFINAGE AMÉLIORÉ DES MACROALGUES BRUNES
Abstract:
(EN) 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.
(FR) La présente invention concerne un procédé amélioré de bioaffinage des macroalgues brunes, qui comprend : (a) la mise en contact des macroalgues brunes avec un système de solvant comprenant au moins 30 % en poids de solvant organique, pour obtenir des macroalgues extraites sous forme de résidu solide et une liqueur ; et (b) le bioaffinage des macroalgues extraites. Les inventeurs ont découvert que la mise en contact de l'étape (a) conduit à une déshydratation efficace et rentable des macroalgues, avec perte de jusqu'à 95 % en poids de leur humidité interne sans avoir besoin de recourir à des techniques de séchage consommatrices d'énergie. De ce fait, le bioaffinage aval des macroalgues extraites est considérablement facilité.
