<p>LIQUID CYCLONE PROCESS A process for the recovery of protein from vegetable protein material is disclosed which involves differential settling and separation of protein bodies and cellular debris from the material by hydro cyclone separation. The process includes the steps of grinding vegetable protein material to a particle size range of less than about 40 microns, preferably less than about 10 microns followed by admixing the ground material with an aqueous suspension medium having a pH of 4.5, separating the protein bodies from the non-proteinaceous material by hydrocyclone separation into underflow and overflow streams, the underflow stream substantially containing intact protein bodies, the overflow stream substantially containing cellular debris and recovering the solids from both streams. The underflow stream which is separated from the aqueous suspension medium provides protein concentration of at least 68% by weight. Further processing of the underflow stream by hydrocyclone separation removes additional soluble salts and carbohydrates to provide protein solids of at least 68 to 82% by weight. The novel process of the instant invention provides for the simultaneous purification and separation of protein bodies from vegetable proteinaceous material to form a protein concentrate.</p> |
