Abstract: A dry-milling process for the production of dried distiller's grains with solubles (“DDGS”) includes the steps of dry-milling corn kernels to form a corn flour comprising corn fiber; combining the corn flour with water to form a mash; separating the corn fiber from the mash; treating the separated corn fiber with a composition; combining the treated corn fiber with the mash having the corn fiber separated therefrom to form a slurry; fermenting the slurry to produce beer and carbon dioxide; distilling the beer to produce ethanol and whole stillage; and processing the whole stillage to produce DDGS. The composition includes an alkanesulfonic acid, water, an enzyme, and optionally a surfactant.
