Abstract: 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.

Abstract: The invention provides a process for producing a baked food of wheat flour by using a soybean protein in which NSI shows a low denature value of 40 or more, the content of solid component extracted with a solvent mixture of chloroform and methanol (2:1) is 2.0 wt % or less, and the crude protein content is 63% or more. When wheat flour in dough is replaced with the soybean protein at a small ratio, baked foods of wheat flour which are resistant to freezing and show good texture even after thawing in a microwave oven can be obtained. Moreover, a process for making a baked food mainly comprising soybean proteins, which has a good taste and texture and is appropriately taken by human, can be provided by replacing most part or all of wheat flour with a soybean protein.

Abstract: 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.
