Process for isolating oil-seed proteins using liquid fluorocarbons

摘要

Cereal or other protein-containing material is ground and mixed with a liquid fluorocarbon whose density is adjusted to 1.35 to 1.45. The resulting slurry is centrifuged, whereby to produce a protein fraction floating on the surface of the liquid, a bottom phase composed mainly of starch, and an intermediate fluorocarbon phase containing fat. The protein phase can be easily separated from the remainder, dried, and used as a dietary supplement or The like. the starch and fat components can also be readily separated from the centrifuged slurry.
