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 a preliminary acid-catalyzed hydrolysis of the starch to provide a sterile hydrolysate slurry, the slurry is further hydrolyzed in the presence of added aqueous non-fermentable carbohydrate to reequilibrate the hydrolysis reaction in favor of increased production of fermentable sugar, primarily glucose. 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 sterile hydrolysate either before or after the further hydrolysis step with the water solubles being recycled to the system to effect reequilibration of a further quantity of hydrolysate.
