Abstract
A method is disclosed for producing glucose from a granular starch substrate including, contacting a slurry comprising granular starch obtained from plant material with an alpha-amylase at a temperature below the starch gelatinization temperature of the granular starch to produce oligosaccharides and hydrolyzing the oligosaccharides to produce a mash comprising at least 20% glucose and further comprising fermenting the mash to obtain ethanol.
