Abstract: Modified and insoluble starches are utilized for eliminating natural organic substances/contaminants from liquids and in particular from liquids used for food applications, such as drinking water, beverages, fruit juices or syrups, as well as natural water, industrial process water, or wastewater.

Abstract: A substantially boron-free method for making a cationic guar comprising: reacting particles of polysaccharide with a derivatizing agent to produce derivatized polysaccharide particles, washing the particles, and contacting, prior to or after the step of washing, the particles with a crosslinking agent compound. Also disclosed are methods for making crosslinked derivatized polysaccharides that include contacting particles of a polysaccharide with a first crosslinking agent and/or second cross-linking agent in an aqueous medium under conditions appropriate to intra-particulately crosslink the particles. The first and/or second crosslinking agent can include a copper compound, a magnesium compound, a calcium compound, an aluminum compound, p-benzoquinone, glyoxal, a titanium compound, a dicarboxylic acid, a dicarboxylic acid salt, a phosphite compound or a phosphate compound.
