Abstract

The present invention relates to a process for separating proteins and/or protein fractions from biomass materials, wherein the process comprises the steps, where in the first step biomass material is mixed with an aqueous DES comprising a hydrogen bond acceptor selected from alkali or earth alkaline metal carboxylates and urea as hydrogen bond donor to obtain biomass mixture; the second step the biomass mixture is separated into a non- solubilized fraction and a liquid fraction; and in the third step proteins are separated using technique based on molecular size from the liquid fraction to yield a protein solution, or using technique based on isoelectric precipitation to yield a protein precipitate.
