Abstract
Aqueous slurries of physically and/or chemically modified starch solids, having high starch solids levels, are purified by means of ultrafiltration. An ultrafiltration system is started by circulating water and then the modified starch slurry is added to raise the starch solids level of the stream fed to the ultrafiltration unit to between 20 and 32% by weight. Water is added to the ultrafiltration system, preferably at the same rate at which water is removed from the system in the permeate. After the desired level of purification is achieved the slurry is concentrated to above 35% and then dried.
