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.

Disclosed is a method for preparing a protein isolate displaying a purity higher than 80% from plant parts, the method including the following successive steps: a) washing the plant parts in acidic conditions, thereby obtaining acid washed plant parts; b) contacting the acid washed plant parts with an alkaline solution; and c) recovering the liquid fraction thereby obtaining a protein isolate displaying a purity higher than 80%. The method does not include any acidic precipitation step.

The group of inventions relates to the food industry, namely, to a method and device for processing brewer's spent grains. The invention makes it possible to obtain a gluten-free protein drink with a protein content of at least 10.0 wt. % dry weight. The principle of the invention is based on the technology of preparing brewer's spent grains for the extraction of nutrients and their extraction by mechanical processing on the proposed industrial line. The essence of the method lies in the fact that brewer's spent grains are loosened on a vibrating screen, crushed in a colloid mill, with the addition of water in a ratio of 0.5:1 to 1:1 with respect to the grains, to obtain a paste-like homogeneous mass, and then this mass is processed in a screw extractor for further grinding and separation into 2 fractions, namely: a suspension with a water content of 90-95%, which all nutrients remain in, including the proteins of the brewer's spent grains, and crushed husks of the brewer's spent grains with a water content of 60-75% suitable for further industrial use. Then, the suspension is subjected to removing suspended particles to obtain the final product—vegetable milk (protein drink), which is pumped into a storage tank.

The present disclosure provides fish-derived peptides with ACE inhibitory activity, and methods of producing peptide isolates comprising the fish-derived peptides. The present disclosure also provides pharmaceutical products, dietary supplements, and functional foods including the peptide isolates, and method of lowering blood pressure of a subject by administering to the subject one or more of the fish-derived peptides.

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.
