Abstract

Previously unrecognized polysaccharide products are extracted from either whole Lesquerella fendleri seed or commercially processed and oil-extracted seed meal or presscake or other seed material. Processes used include the steps of: (1) combining the seed material with an aqueous solution; (2) high speed stirring or sonification of the resultant seed material for the separation of the polysaccharide from the seed; and (3) isolation of the polysaccharide from the aqueous filtrate. The resultant polysaccharides are highly polymeric and enhance solution viscosities over a wide range of pH, bleaching and salt conditions.
