Title
(EN) PLANT-DERIVED RUBISCO PROTEIN PURIFICATION
Abstract
(EN) The disclosure describes methods for the purification of protein- enriched extracts to provide concentrates and isolates and methods for incorporation of such materials into products. The purification methods are adapted for removal of, e.g., chlorophyll and may thus provide lightening the color of the protein-enriched extracts. The methods generally include treatment with peracetic acid and filtrations. A protein composition in the form of a concentrate or isolate is provided, the protein composition including RuBisCO, F2 fraction proteins, or combination thereof extracted from a plant material.
