Abstract
A novel process for making an isoflavone concentrate product from soybeans which includes diluting solubles from alcohol-extracted hexane-defatted soybean flakes to about 10% to about 30% solids, separating undissolved solids from the diluted soy solubles and drying the separated solids to make a product having at least 4% by weight isoflavones. The soy isoflavone concentrate product is then used in a liquid or dry beverage, food or nutritional product.
Claims20
A method for making an isoflavone product by separating undissolved solids from solubles from alcohol-extracted hexane-defatted soybeans, with said solids forming said product having at least 4% isoflavones by weight of dry matter and a genistin to daidzin ratio of about 1-3 to 1.
A method for making an isoflavone product by aqueously separating undissolved solids from desolventized solubles from alcohol-extracted hexane-defatted soybean flakes without substantial conversion of daidzin to daidzein, with said solubles having a genistin to daidzin ratio of about 1-1.5 to 1 and said solids forming said product having at least 4% isoflavones by weight of dry matter, about 50% carbohydrate by weight of dry matter, less than 40% protein by weight of dry matter, about 5-10% saponins by weight of dry matter and a genistin to daidzin ratio of about 1.5-2 to 1.
A method for making a phytochemical product by aqueously separating undissolved solids from alcohol-extracted soy solubles, with said solids forming said product having at least 4% isoflavones by weight of dry matter and at least 4% saponins by weight of dry matter.
