Abstract
A corn-to-ethanol production process is disclosed. The process includes the steps of dry-milling corn kernels to form a corn flour; combining the corn flour with water to form a mash; extracting corn oil from the mash; fermenting the mash thereby producing beer and carbon dioxide; distilling the beer to produce ethanol and whole stillage; and processing the whole stillage to produce wet distiller's grains with solubles (WDGS) and/or dried distiller's grains with solubles (DDGS). The step of extracting corn oil from the mash includes the sub steps of: optionally wet-milling the mash; separating the mash to produce a light phase and a heavy phase; adding an alkanesulfonic acid to the light phase; extracting corn oil from the light phase; and combining the light phase having the corn oil extracted therefrom with the heavy phase to reform the mash.
