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

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.
