Abstract: The present inventors found that the natural flavor intrinsic to soybean is retained more than ever before when soybean is processed to prepare a processed soybean material having a specific lipid content, a dietary fiber content, an acid-soluble component content and a protein content, whereby the present problems were solved. More specifically, the processed soybean material of the present invention is such that, on a solid weight basis, (1) a content of lipid, extracted with a mixed organic solvent wherein a ratio of chloroform to methanol is 2:1, is 10 to 40% by weight, (2) a dietary fiber content is 5 to 40% by weight, (3) a potassium content is 1% by weight or less, (4) a protein content is 30 to 65% by weight, and (5) a sum of ?-conglycinin and 24 kDa protein is 2.4 times or less of lipoxygenase protein in soybean proteins.

Abstract: A fat-reduced soybean protein material containing a protein and a carbohydrate at a total content of 80 wt % or more in terms of dried form content, containing a fat (as an extract from a chloroform/methanol mixed solvent) at a content of less than 10 wt % relative to the content of the protein, and containing campesterol and stigmasterol (as plant-derived sterols) at a total content of 200 mg or more relative to 100 g of a fat; and a soybean emulsion composition containing a protein at a content of 25 wt % or more in terms of dried form content, containing a fat at a content of 100 wt % or more in terms of dried form content relative to the content of the protein in terms of dried form content, and having an LCI value of 60% or more.

Abstract: Disclosed is a process for fractionating soybean protein into 7S globulin, 11S globulin or a lipophilic protein at a high purity with good efficiency, which relates to a fractionation technique for soybean protein into proteins having characteristic properties (7S globulin, 11S globulin and a lipophilic protein) and which is a process practicable at a food industrial level. It is found that soybean protein can be fractionated into 7S globulin, 11S globulin or a lipophilic protein at a high purity with good efficiency by extracting soybean milk from processed soybean which has been subjected to a water-insolubilization treatment specific to a desired protein and fractionating the resulting soybean milk or soybean curd refuse into the desired protein.

Abstract: It is intended to provide a soy protein gel which has such gel properties that have never been obtained hitherto and is excellent in taste and color tone, and a soy protein food taking advantage of the gel properties. It has been found out that gel properties can be modified at an extremely elevated level and thus the desired soy protein gel can be obtained by preparing a gel by using a soy protein material in which the lipophilic protein content is reduced and conducting the gelation with the utilization of not only heat but also the action of a protein crosslinking enzyme.

Abstract: It is intended to prepare noodles and noodle skins, in particular, wheat flour-free noodles and noodle skins, which comprise a soybean protein composition at a high ratio. By adding a water-extracted less denatured soybean protein to noodles and noodle skins, noodles and noodle skins containing a large amount of the soybean protein can be obtained. Further, it is possible to obtain wheat flour-free noodles and noodle skins and starch-free noodles and noodle skins.

Abstract: The present invention is to provide a method for obtaining more efficiently isolated-soy protein, which has excellent gelation properties and shows neither bitterness nor astringency characteristic to soybean, while reducing the amount of water used in a soy protein manufacturing plant and thus lessening burden on the environment owing to the reduction in discharged water. It is a method for producing isolated-soy protein, including: an acid-washing step of washing defatted soybeans with an aqueous medium in a region of pH 3.0 to 5.0 to extract and remove whey components; an extraction step of extracting protein from acid-washed soybean slurry obtained in the acid-washing step with an aqueous medium in a neutral to alkaline region and then removing an extraction residue; and an isolation step of separating the extract solution obtained in the extraction step into water and protein while holding it in the neutral to alkaline region.
