Publication number: 20150181911Abstract: Feed compositions and methods of making feed compositions are disclosed herein. The feed compositions may include, on a dry weight basis, crude protein in an amount of about 40 wt % or greater, crude fat in an amount of up to about 20 wt %, neutral detergent fiber in an amount of up to about 20 wt %, and lysine in an amount of about 2.55 wt % or greater. The methods involve separating a beer composition produced by a starch-based feedstock-to-ethanol conversion process into bulk solids and a fine solids, and removing liquid from the fine solids, in which the separating and removing are performed in a manner that reduces the total heat exposure of the fine solids as compared to processes relying on distillation to separate beer components and/or cooking to saccharify starch.Type: ApplicationFiled: January 16, 2015Publication date: July 2, 2015Applicant: POET Research, Inc.Inventor: Steven G.

Publication number: 20150181912Abstract: Protein feed compositions and methods of making the protein feed compositions are disclosed herein. The protein feed compositions may comprise zein and are derived from a starch-based feedstock-to-ethanol fermentation conversion process such as a corn-to-ethanol conversion process. Methods of making the compositions include performing a starch-based feedstock-to-ethanol fermentation process in a manner that reduces the total heat exposure of the components of the protein composition as compared to a similar process which uses a cooking process to saccharify starch and/or a distillation process to separate the fermentation beer into ethanol and whole stillage. The process may include centrifugation of the fermentation beer resulting in a bulk solids mixture, extraction of a protein composition from the resulting bulk solids mixture, and desolventizing the extracted protein composition.Type: ApplicationFiled: January 16, 2015Publication date: July 2, 2015Applicant: POET Research, Inc.Inventor: Steven G.
