IMPROVED STARCH PURIFICATION BY THERMALLY TOLERANT BROAD pH RANGE PROTEOLYTIC ENZYMES

摘要

The present invention is directed to purifying starch granules from starch-bearing crops, preferably maize, which include treating starch granules with a thermally tolerant, broad pH range proteolytic enzyme that is specific for surface-associated proteins. Also disclosed are purified starch granules which are substantially free of surface-associated proteins. Uses of the isolated starch granules are disclosed.
