摘要:
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.
摘要:
A neutral particulate soybean protein having an extremely reduced odor called “soybean odor” which is present in a soybean protein and derived from soybeans and also having an excellent flavor without deteriorating the flavor associated naturally with a processed food product when used in such food. Also a method for producing a neutral soybean protein which comprises heating a soybean protein slurry or solution under acidic conditions followed by neutralization (to pH 6.0 to 8.0) preferably followed by heating again.

The present invention addresses the problem of providing a soybean-derived raw material-containing food or beverage that improves problems with flavor and physical properties, such as the grassy smell caused by soybean raw materials, and markedly improves product quality, in a soybean-derived raw material-containing food or beverage using conventional soybean raw materials such soymilk or tofu. Provided are a milk-substitute composition, and an egg-yolk substitute composition, etc., characterized by including a soybean emulsion composition having a protein content relative to dry material of at least 25 wt %, a fat content (as a chloroform/methanol mixed solvent extract) relative to the protein content of at least 100 wt %, and an LCI value of at least 55%. Also provided are a variety of soybean-derived raw material-containing food and beverages using these compositions.

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.

The object is to fractionate 7S-globulin as well the remaining acid-precipitatable proteins from a soybean with efficiency and at high purities, and provide a highly pure fractionated soybean protein material. Specifically disclosed is a method for producing a fractionated soybean protein material, which comprises the steps of: 1) extracting a protein from a soybean having a 7S-globulin content of 20 wt % or more and a 11S-globulin content of 10 wt % or less relative to the total amount of proteins, thereby producing a soybean protein solution; 2) adjusting the pH value of the soybean protein solution to 4 to 5.5, and heating the resulting solution at 40 to 65° C.; and 3) adjusting the pH value of the heated soybean protein solution to a value ranging from 5.3 to 5.7 and higher than the pH value at the time of the heating the solution, and fractionating the resulting solution into a water-soluble fraction and a water-insoluble fraction.

Disclosed are: a fat-reduced soymilk having a reduced fat content, which is produced by separating a fat from a fat-containing soybean efficiently without relying on an organic solvent; and a novel fat-rich soybean material. Specifically disclosed are: a fat-reduced soybean protein material characterized by 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 characterized by 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.
摘要:
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.

摘要:
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 γ-conglycinin and 24 kDa protein is 2.4 times or less of lipoxygenase protein in soybean proteins.
