FRACTIONATION AND ISOLATION OF 7S AND 11S PROTEINS FROM ISOELECTRICALLY PRECIPITATED VEGETABLE PROTEIN MIXTURES

摘要

ABSTRACT OF THE DISCLOSUREThe 7S and 11S proteins of vegetable proteins may be effectivelyfractionated and isolated by selectively extracting 7S proteins from anisoelectrically precipitated mixture of 7S and 11S protein in the presenceof water-soluble salts. The initial 7S extraction is typically conductedat a pH 5.0-5.6. An enriched 11S fraction is recovered by separating thewater-insoluble 11S protein from the water-soluble enriched 7S extract.
