A method for obtaining one or more fiber rich and one or more protein rich fractions from spent grain, SG, the method comprising: dehydrating (S1) wet spent grain, WSG, into dehydrated spent grain, DSG, by arranging the WSG on at least one dehydration surface, wherein the dehydration surface comprises a net with apertures arranged to allow air to penetrate without the spent grain falling through, and wherein a conditioned air movement system is arranged to move air over, under the dehydration surface as well as through the apertures, and comminuting (S2) the DSG by a comminution reactor comprising a spinnable shaft and two or more processing chambers, separated by segmented divider plates, wherein each processing chamber comprises one rotor disc attached to the shaft and one or more vortex generators placed at respective apex corners of stationary side walls of the processing chambers, wherein the DSG is fed into the comminution reactor and fiber-rich and protein-rich fractions are liberated from the DSG by means of a non-linear vortex flow of DSG and liberated products generated in the processing chambers.

The present invention provides a novel IL-1β and/or IL-6 expression inhibitor and use thereof. The IL-1β and/or IL-6 expression inhibitor in accordance with an aspect of the present invention contains a component derived from alcoholic fermentation lees.

The present invention relates generally to corn dry-milling, and more specifically, to methods for producing a high protein corn meal from a whole stillage byproduct produced in a corn dry-milling process for making ethanol and a system therefore. In one embodiment, a method for producing a high protein corn meal from a whole stillage byproduct includes, in a corn dry-milling process for making ethanol, separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. The thin stillage portion is separated into a protein portion and a water soluble solids portion. Next, the protein portion is dewatered then dried to define a high protein corn meal that includes at least 40 wt % protein on a dry basis.

A method and system for improving ethanol production from biomass are provided which includes adding at least one separation aid to stillage, that is preferably whole stillage, that contains oil and/or fat generally in the form of an emulsion, to form a treated stillage prior to centrifuging the stillage, and centrifuging the treated stillage in at least one centrifuge to separate at least a portion of the solids content from the treated stillage. The separation aid contains at least one anionic surfactant, at least one non-ionic surfactant, at least one organic solvent that is miscible in water, and water, and optionally at least one lecithin. Treated stillage products are also provided which can contain the indicated separation aid.
