Process For Producing A Fermentation Product

Abstract

The present invention relates to processes of producing a fermentation product from starch containing material comprising (a) forming a slurry comprising the starch-containing material and water; (b) converting the starch-containing material into dextrins with an alpha-amylase; (c) saccharifying the dextrins using a carbohydrate source generating enzyme to form sugars; (d) fermenting sugars using a fermenting organism; (e) recovering the fermentation product to form whole stillage; (f) separating the whole stillage into a liquid fraction thin stillage and solid fraction wet cake; (g) hydrolyzing the thin stillage; (h) recycle a portion of the hydrolyzed thin stillage to steps (a); wherein the thin stillage in step (g) is hydrolyzed using a glucoamylase and/or polygalacturonase.
