ABSTRACT:
A cold-water-swellable granular starch which affords aqueous solutions or dispersions having high-viscosity and/or excellent clarity is provided. In one embodiment, the granular starch is made cold-water swellable by contact with aqueous alcohol, then derivatized with an .alpha.-halocarboxylic acid, and then isolated under condition which inhibit esterification of the granular starch, e.g. high pH, to afford a starch that has excellent paste clarity. In other embodiments, the cold-water-swellable granular starch is crosslinked to afford a starch that has very high paste viscosity.
