A fractionation strategy for Saccharina latissima algal biomass was developed utilizing chelating extraction salt solutions to mediate the liberation of components. Alginate, cellulose, laminarin, mannitol, protein, and inorganic salts were quantified in fractions reveal their individual dissolution patterns. Chelation power identified as a key parameter liberating alginate increasing yield extracted The most efficient achieved using aqueous sodium citrate solution, producing an alginate-rich soluble fraction salt-poor insoluble rich cellulose protein. Extractions at decreased pH shown be beneficial because they M/G ratio concentrated protein from which it can easily recovered; these effects could by switching traditional carbonate solution with that have chelation capacity lower pH. cyclic demonstrated reused multiple extractions buildup concentrations other valuable components solution.
