Brown seaweed consists of about 2000 species, making it the second most abundant group of marine algae. Fucoidan (FU) is composed of fucose, uronic acids, galactose, xylose and sulphated fucose. Alginate (AG) is gelling in presence of divalent ions like calcium and consequently it is widely used as a food ingredient. Recently, the extraction methods employing ‘green technology’ have been preferred these technologies allow for the extraction of natural ingredients without the need of toxic or chemical solvents in various industry. In this regard, pressurized liquid extraction (PLE) is an excellent choice for the production of extract with functional activity from brown seaweed. Deep eutectic solvents (DESs) were recently discovered, which can be used as an alternative solvents to conventional solvents. In the process of PLE, DESs will be employed as a solvent at elevated temperature under pressure modifies the dielectric constant and changes its polarity, thus selectively extracting different classes of compounds. The objectives of this study was to PLE combine with DESs as a green technology can be used for the extraction of FU and AG from brown seaweed. |
