摘要

A process to isolate protein from the meal or oil cake comprising the following steps: • extracting the meal with water to obtain an aqueous solution; • concentrating the aqueous extract to an aqueous solution comprising 5 to 30 wt% protein, preferably 10 to 30 wt% protein; • adding a water-soluble solvent to the concentrated aqueous solution to obtain a protein precipitate; and • separating the protein precipitate from the liquid fraction.
