Abstract
Methods for production of ethanol, distiller's corn oil, and enhanced co-products are disclosed. Methods include obtaining a mixture of one or more co-products of an alcohol production process, which may include wet cake, performing hydrolysis of polysaccharides in the mixture to generate fermentable sugars, fermenting the fermentable sugars in the mixture to produce alcohol, distilling the mixture to remove alcohol from the mixture thereby producing alcohol-containing distillate and enhanced whole stillage, removing released oil from the fermented mixture before distillation and/or from the enhanced whole stillage after distillation, and recovering enhanced wet distiller's grains, enhanced thin stillage, and/or enhanced dried distiller's grains. Compositions disclosed herein include enhanced dried distiller's grains having a crude protein content of at least 45% on a dry weight basis and having a total fat content of less than 10% on a dry weight basis.
