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.
