Abstract
Abstract COLD-WATER-SWELLING STARCHES WHICH FORM AQUEOUS PASTES OF EXCEPTIONALLY HIGH VISCOSITY ARE PREPARED BY SUBJECTING, IN A CONFINED ZONE, A SLURRY OF WAXY STARCH, A SOLVENT FOR STARCH, AND AN ORGANIC LIQUID WHICH IS MISCIBLE WITH THE SOLVENT FOR STARCH, TO GELATINIZING CONDITIONS. THE TREATMENT CONDITIONS AND PROPORTIONS OF INGREDIENTS ARE SO SELECTED TO CAUSE FROM 0% TO ABOUT 75% OF THE WAXY STARCH GRANULES TO BECOME FRAGMENTED, AND THE NON-FRAGMENTED GRANULES TO BE NON-BIREFRINGENT. AFTER TREATMENT THE SLURRY ID COMBINED WITH ADDITIONAL ORGANIC LIQUID, AND THE PROCESSED STARCH IS THEN RECOVERED.
