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.

Fractionated soybean protein material, processed soybean suitable for the material, and processes for production of the soybean protein material and the processed soybean

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 a conventional soybean raw material such soymilk or tofu. Provided are a milk-substitute composition, an egg yolk-substitute composition, and a composition for improving renal function, etc., characterized by including a reduced-fat soybean protein material having a total protein and carbohydrate content relative to dry material of at least 80 wt %, a fat content (as a chloroform/methanol mixed solvent extract) relative to the protein content of less than 10 wt %, and a total campesterol and stigmasterol (as plant-derived sterols) content of at least 200 mg relative to 100 g of fat. Also provided are a variety of soybean-derived raw material-containing food and beverages using these compositions.

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.

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&#xb0; 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.

Method for production of fractionated soybean protein material

A soybean protein beverage having an excellent taste and mouthfeel and high storage stability with preventing formation of a precipitate at a weak acidic region as well as its production process are shown. Said beverage utilizes as its protein source low-phytic acid &#x3b2;-conglycinin obtained by fractionating and purifying &#x3b2;-conglycinin which is a soybean protein fraction and further decomposing and removing phytic acid bound to the resultant &#x3b2;-conglycinin to increase the solubility at a weak acidic region.

Protein beverage

A method for fractionating a soybean protein into highly pure 7S globulin and 11S globulin efficiently in an industrial scale is provided, said method comprising warming a solution containing a soybean protein under a weakly acidic condition followed by fractionating at pH 5.6 to 6.6 into a soluble fraction and an insoluble fraction. If necessary, a treatment with a phytase may also be employed in the production method to fractionate into a 7S globulin and a 11S globulin.

The present invention provides a neutral fat reducing composition which reduces a blood neutral fat safely and efficiently, and whose active ingredient is a soybean protein containing 50% or more of a 7S globulin fractionated from a soybean protein and 0.2% or less of phytate based on the proteins. Its effect is further enhanced by removing a oil-body-associated protein and reducing a chloroform methanol-extractable oil fraction.

Composition for diminishing neutral fat in blood

A method for fractionation of soybean protein into a 7S globulin-rich fraction and an 11S globulin-rich fraction which comprises treating a soybean protein-containing solution with an enzyme or an enzyme preparation having an activity of decomposing phytic acid to thereby separate into a soluble fraction and an insoluble fraction at a specific pH value.
