There is provided an improved process for the separation and purification of plant proteins by initially separating the chloroplastic and cytoplasmic protein fractions, further treating the chloroplastic protein fraction enzymatically and extracting out other unfavorable substances. The resulting chloroplastic fraction has favorable properties close to that of the cytoplasmic fraction and is thus valuable for human consumption.

A process for the separation and purification of plant proteins from the pressed juice of green plants comprising (a) coagulating a chloroplastic protein fraction in form of a green sludge from said juice at a temperature below 50°C. in the presence of an inorganic flocculating agent; (b) separating said green sludge from a remaining juice and subjecting the sludge in an aqueous suspension to a protease enzyme until about 5% by weight of the protein components are degraded; (c) extracting said sludge after enzymatic treatment with at least one polar solvent such that the water to solvent ratio is at least 80:20 to remove pigments and lipids from protein; (d) isolating an extracted pigment and a lipid concentrate by distilling off the solvent and drying the residue, and (e) isolating a cytoplasmic protein fraction by coagulating the remaining juice from step (b) at a temperature of about 80°C., separating and drying the protein precipitate.
