Abstract
A process for the preparation of granular cold water swelling/soluble starches by alcoholic-alkali treatments is disclosed which comprises contacting a quantity of starch granules with respective quantities of an alcohol and a strong base to swell the granules and convert the starch to form having increased cold water solubility. The process can be used on waxy, high amylose, tuber, and normal starches. The resulting cold water swelling/soluble starch preferably exhibits about 50% to 94% solubility in cold water.
