OILSEED PROTEIN CONCENTRATE AND PROCESS FOR THE PRODUCTION THEREOF

摘要

A process for producing a protein concentrate from oilseed from a plant of a family selected from the group consisting of Brassicaceae, Cannabaceae, Pedaliaceae, Rosaceae, and Fabaceae, preferably Brassicaceae. The method comprises the successive steps of: a) providing a presscake from at least partially dehulled oilseed; b) washing said presscake by mixing it with a first hydrous-alcohol solvent to obtain a washed presscake, and eventually separating said washed presscake from said first hydrous-alcohol solvent, to obtain a washed, an eventually separated, presscake, wherein said first hydrous-alcohol solvent has an alcohol concentration ranging from 60 % to 75% w/w; and c) washing said washed, and eventually separated presscake by mixing it with a last hydrous-alcohol solvent to obtain a protein-containing solid and separating said protein- containing solid from said last hydrous-alcohol solvent to obtain a protein concentrate, wherein the alcohol concentration of the final hydrous-alcohol solvent is about the concentration of the azeotrope.
