Abstract: The present invention relates to a method of processing macroalgae in which superheated water is used in an initial pre-treatment step prior to extraction of a polysaccharide. In particular, the invention relates to a process for obtaining polysaccharide (e.g. alginate) from macroalgae or a part thereof. Certain aspects of the invention relate to a process for obtaining polysaccharide from macroalgae which results in enhanced polysaccharide yield and/or a shortened treatment time when compared to conventional extraction methods.

Abstract: The present invention is a method of extracting the oxygen-containing flavor and fragrance compounds from oils obtained from natural products. Extraction is accomplished by the use of cold water typically below 100° C., but more typically below 50° C., to produce a weak aqueous solution. The oxygen-containing compounds are then concentrated by adsorption on to an appropriate solid material and then washed off by an organic solvent, such as ethanol. The resulting product is a solution in the organic solvent.
