The present disclosure provides systems and methods for the recovery of protein species from wet mill grain process streams. Systems and methods of the present disclosure may be integrated with a wet mill grain process to separate out protein species that may limit efficiency of the grain process and produce one or more product streams comprising these separated protein species. A feed stream may be fractionated by at least two membranes into retentate and permeate streams. Removing larger proteins through the membrane fractionation may allow previously soluble prolamin products in the permeate stream(s) to precipitate. The recovered protein species may include prolamin, such as zein from a corn grain feed.

The present invention provides a process for the production of a protein powder having an improved solubility and taste profile from brewer's spent grain. The process comprises nanofiltration at a specified applied pressure. The present invention also provides a protein powder produced from brewer's spent grain, a process for producing food or beverage products incorporating the protein powder, and food or beverage products comprising the protein powder.

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.

A process for extraction of crude oil from distillers dried grain solubles and/or distillers dried grains using a solvent extraction process and producing corn distillers meal that may be used as an animal feed supplement is disclosed. The corn distillers meal may be used as a crude protein supplement for use in a livestock feed diet, poultry feed diet, aquatic feed diet or the like. The solvent extracted crude oil may be suitable for other processes, including oleochemical processing for personal care and home care products, biodiesel production, and/or renewable diesel production from hydro-treating the extracted oil to make green diesel fuel.

A process prepares a beverage or beverage component. The process includes an enzymatic treatment of brewer's spent grain including addition of one or a combination of enzymes with alpha-amylase, gluco-amylase, cellulase, xylanase, protease and/or beta-glucanase activity and fermentation by a strain of lactic acid bacteria. The combination of enzymes and enzymatic treatment conditions is such that the lactic acid bacteria produce 4.5 g/L lactic acid and metabolise sugar such that the resulting fermented broth contains less than 2.5% w/w and preferably less than 0.5% w/w residual sugar or the lactic acid bacteria produce 4.5 g/L lactic acid and metabolise sugar such that the resulting fermented broth contains at least 2.5% w/w residual sugar.

The invention pertains to the field of oat protein compositions and production method thereof. In particular, the present invention is directed to an oat protein composition having low lipid content and which does not contain traces of organic solvent and to the production method thereof.

This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.
