PRODUCTION OF RAPESEED PROTEIN MATERIALS

摘要

A process of treating meal containing vegetable proteins is disclosed. This process includes the step of extracting the meal with a suitable aqueous solvent in which the vegetable proteins are soluble to obtain an extraction solution. The solubility of the dissolved protein in the extraction solution is then adjusted to precipitate at least some of the protein and therefore obtain a precipitated protein fraction and an unprecipitated protein fraction in solution. The precipitated protein fraction is then separated from the protein fraction in solution, and the unprecipitated protein fraction is separated from the undesirable components in the solution by membrane processing. Each of the protein fractions is then suitably dried to recover the proteins.
