ABSTRACT:
A novel protein isolate derived from vegetable oilseed protein is disclosed that is substantially free of impurities. More particularly, a novel soy protein isolate is disclosed which is substantially devoid of color and lacks the characteristic "beany" flavor of soybeans. The protein isolate is produced by extracting a ground oilseed material, such as soybean meal, with an alkaline extractant to provide an alkaline protein extract with a pH of at least about 9.5, passing the alkaline extract through activated carbon to deflavorize and decolorize the protein material, followed by precipitation and isolation of the deflavorized protein.
