A protein product and an extraction method for making the protein product. Raw materials of the product optionally contains macromolecular carbohydrates and/or fat, and the method does not use organic solvents. The protein product contains prolamin and carbohydrates, wherein the prolamin accounts for 70 wt % or above of the protein (dry-basis), the α-prolamin accounts for 75 wt % or above of the prolamin, the β-prolamin accounts for 20 wt % or below of the prolamin, and the γ-prolamin accounts for 6 wt % or below of the prolamin.

The present technology generally relates to food-processing industry, namely to a method of processing brewer's grains. The invention enables to increase the level of extracted food fractions of brewer's grains up to 90-95% and to increase protein content in barley protein concentrate up to 50-65% wt (dry solid). The method implies that brewer's grains are subject to loosening by means of a vibrating screen, grinding in a colloid mill with addition of water or centrate in the ratio from 0.5:1 to 1:1 to brewer's grains in order to produce a pasty homogeneous mass from brewer's grains; and then this mass is subject to processing by means of a screw extractor for its further grinding and division into 2 factions: suspension with the humidity level of 90-95%, and ground husk of brewer's grains with the humidity level of 60-75% suitable for its further industrial use. Then the suspension is supplied to mechanical filtration in order to remove the ground husk, pumped into the container and dried in order to obtain the humidity level of max. 7%.

This paper describes a concentrated sweet potato leaf protein in dried form, along with methods for producing it. The concentrated leaf protein is high in protein content, high in purity, and can have other beneficial components such as polyphenols. The concentrated leaf proteins are suitable for use in food and beverages, as protein supplementation, or as agents for gelling, foaming, whipping and the like.

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

A method and system for producing at least one byproduct from spent grains, such as Brewer's Spent Grains or Distiller's Spent Grains. In one embodiment, the spent grains are preserved via a preservation treatment before being put through a cellulase treatment. The cellulase treated spent grains are then filtered to produce at least one byproduct.

The present disclosure relates to food compositions, particularly pet food compositions, having a high content of plant protein. The plant protein is prepared by processing Brewer's Spent Grain (BSG), having a moisture content of about 15% to about 35% by weight, so as to reduce the particle size of the BSG and separating the processed BSG so as to provide a low particle size, high protein fraction.

Processes for separating and isolating proteins and fats from biomass matter utilizes a pH adjustment of a slurry. The biomass feedstock is derived from commingled animal and/or plant-based streams with highly variable concentrations of fat, proteins and impurities present in the biomass. A wide range of pH adjustment spanning highly acid to highly basic has been shown to be effective at separating the commingled streams into their constituent products. The processes do not rely on the proteins being solubilized into the solution, but rather solubilizing the fat portion, physically separating the constituents and precipitating the fat in a downstream process, resulting in two value streams: a highly digestible protein component and a fat component. The protein component has nutritional value as companion pet, animal and aquaculture feed ingredient and the fat component has value as standalone or blended solid or liquid biofuels, greases or specialty chemicals.

The invention relates to a process for a protein product from thin stillage, the process comprising the steps of: producing a first mixture from i) thin stillage and ii) a first aqueous solution or a first organic solvent; separating a solid phase from the first mixture by means of a first solid-liquid separation; producing a second mixture from i) the solid phase and ii) a second aqueous solution or a second organic solvent, provided that the first mixture and/or the second mixture must contain an organic solvent; and separating a solid phase from the second mixture by means of a second solid-liquid separation, wherein the solid phase comprises or includes the protein product.
