Abstract
Starch derived from a dry milled cereal grain such as corn or milo is hydrolyzed to provide a sterile aqueous fermentable sugar solution which is especially adapted for fermentative conversion to ethanol with minimum thermal expenditure. Following an initial acid-catalyzed hydrolysis to thin, or liquefy, the starch, substantially all of the water insoluble protein and oil components, and a portion of the water soluble components, e.g., sugars, proteins and vitamins, are separately recovered from the partial starch hydrolysate with the water solubles being recycled to the system. Thereafter, the partial starch hydrolysate is subjected to further hydrolysis in the presence of an acidic cationic exchange resin as catalyst to provide an aqueous solution of fermentable sugar.
