Abstract:
1. A soy protein material, comprising: a protein content of at least about 55.0 wt. % of total dry matter; an isoflavone content of less than about 200 μg/g of total dry matter; and a soyasapogenols content of at least about 1000 μg/g of total dry matter; wherein the soy protein material is prepared by a process comprising the steps of: providing a substantially defatted soybean material; mixing the defatted soybean material with water to form a protein extract and a slurry of insolubles; separating insolubles to form a liquor; heat treating the liquor; ultrafiltering the liquor, using an ultrafiltration membrane having a molecular weight cut-off between about 5,000 and about 60,000; subjecting the retentate liquor to an adsorption process to remove isoflavones; and pasteurizing the isoflavones-depleted liquor.
