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.

Fractionated soybean proteins and method for producing the same

An edible material containing soybean cell walls having a good taste is produced by providing dehulled and hypocotyl-removed soybeans without substantial swelling by water absorption; soaking and heating the soybeans in hot water to which an alkali has been added under the conditions of: Log(Hr)+0.0333 Temp.gtoreq.2.4, wherein Log(Hr) represents the common logarithm (to base ten) value of a soaking time (hours), and Temp represents a soaking temperature (.degree.C.); and then crushing the soybeans.
