By heating a solution or paste containing soybean &#x3b2;-conglycinin protein under acidic conditions, it is possible to provide soybean &#x3b2;-conglycinin protein whose high hydration property and high viscosity, which are problematic in various food processing using it or at the time of ingestion thereof, are improved.

Processed soybean &#x3b2;-conglycinin protein

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.
