Abstract
An entirely aqueous method for concentrating water soluble polysaccharides having molecular weights of at least about 50 kDa. The method comprises evaporating a water soluble polysaccharide-containing solution until surface film formation occurs, and harvesting the resulting film which is enriched in the polysaccharide. The polysaccharide may be of plant or animal origin, and includes polysaccharides such as guar gum, xanthan gum and pectin.
Claims14
An isolated water soluble mixed linkage (1→3)(1→4) beta glucan-enriched solid film formed from a water soluble mixed linkage (1→3)(1→4) beta glucan-containing solution by heating said solution to allow evaporation therefrom, whereby a solid film enriched in beta-glucan is formed on and isolated from the surface of said solution, such that most of the impurities present in the solution prior to film formation are left behind in the solution when compared to the amount of impurities present in the formed film wherein said water soluble mixed linkage (1→3)(1→4) beta glucan has a molecular weight of at least about 50 kDa.
A method for preparing concentrated water soluble polysaccharide having a molecular weight of at least about 50 kDa by evaporating water from an aqueous water soluble polysaccharide-containing solution, whereby a solid film enriched in polysaccharide is formed on the surface of said solution, and separating said solid film from said aqueous water soluble polysaccharide-containing solution, such that most of the impurities present in the solution prior to film formation are left behind in the solution after said separation when compared to the amount of impurities present in the formed film.
