Abstract: A soy isoflavone concentrate that has an isoflavone content of 50 wt. % moisture free basis (“mfb”) or greater. The process for producing the soy isoflavone concentrate uses a combination of an ultrafiltration process and a liquid-liquid extraction to obtain a high soy isoflavones concentration without the need for additional extraction or purification steps. A soy isoflavone concentrate is provided having at least 50 wt. % isoflavones (mfb), inclusive of at least 15 wt. % daidzin (mfb), at least 20 wt. % genistin (mfb), and at least 4 wt. % glycitin (mfb). A process for producing the soy isoflavone concentrate includes the steps of providing soy molasses or soy solubles, diluting the soy molasses with water, ultrafiltering the solubles from the water-diluted soy molasses to obtain a permeate, and extracting the permeate with ethyl acetate to obtain an extract that has at least 50 wt. % isoflavones (mfb).

Abstract: A soy protein material having a very low isoflavones content and a high saponins content is produced by a process that involves removal, by adsorption, of isoflavones from a soy protein material obtained by removing fiber from soy flour or flakes. The soy protein material also has a high Nitrogen Solubility Index (“NSI”). The low isoflavones, high saponins soy protein material has at least about 55.0 wt. % protein, less than about 200 &mgr;g/g isoflavones of total dry matter and at least about 1000 &mgr;g/g soyasapogenols of total dry matter. The process for producing the low isoflavones, high saponins soy protein material involves removing fiber from a defatted soybean material and obtaining a liquor that is subsequently pasteurized. Next, sugars and other small molecular weight components are optionally removed from the liquor using membrane separation to increase the protein content of the final material.

Abstract: A process to obtain a highly soluble, low viscosity, salt tolerant gelling vegetable protein product. When introduced into a suitable meat injection brine, the protein product is capable of forming a firm sliceable meat piece with high water retention and no visible signs of the injected brine. When included in gel-based food products such as meat analog formulas, the protein product is capable of forming the desired gel structure, such as firm, sliceable meat-like pieces.

Abstract: A soy protein isolate that has increased amounts of isoflavones and saponins and a high Nitrogen Solubility Index (“NSI”) is produced by a process that involves ultrafiltration and the avoidance of isoelectric precipitation. The soy protein isolate has at least about 90.0 wt. % protein of total dry matter; an isoflavone content of at least about 1.0 mg/g isoflavones of total dry matter; a Nitrogen Solubility Index (“NSI”) of at least about 75%; and wherein a solution of about 12.0 wt. % of the soy protein isolate in water at a temperature of about 22° C. has a viscosity of less than about 500 centipoise (cp). The isolate is high in saponins and has at least 2.0 mg/g soyasapogenols. The process for producing the soy protein isolate involves removing fiber from a defatted soybean material and obtaining liquor that is subsequently pasteurized.

Abstract: A soy protein concentrate having desirable flavor and functional properties, which is low in non-digestible oligosaccharides. The soy protein concentrate is substantially free of galactinol, a component which is present in soybeans which are developed to have a low non-digestible oligosaccharide content. The soy protein concentrate is also rich in isoflavones and also has a high Chymotrypsin Inhibitor (“CI”) content. The method for manufacturing the soy protein concentrate uses an enzyme such as a glycosidase enzyme, and retains the natural level of isoflavones occurring in soybeans.

Abstract: A Bowman-Birk Inhibitor Concentrate (BBIC) that has a high protein content. The BBIC is made from conventional soybeans using ultrafiltration, without acid or alcohol extraction or acetone precipitation.

Abstract: A soy protein with a high molecular weight. The high molecular weight soy protein has desirable flavor and functional properties, such as high water solubility and emulsification and low sedimentation and viscosity. The method of manufacturing the protein uses soy flour and aggregates its low molecular weight proteins into high molecular weight proteins without using aqueous alcohol to modify the structure of the protein.

Abstract: A method for manufacturing a soy protein concentrate having a low non-digestible oligosaccharide and high isoflavone content. The soy protein may have high saponin content. The method includes the use of a membrane in an ultrafiltration process to separate non-digestible oligosaccharides from protein, while retaining isoflavones and saponins with protein. The soy protein concentrate with a low non-digestible oligosaccharide and high isoflavone and saponin content is useful as a milk substitute and in drink mixes as well as an ingredient in other nutrition and health products.
