Abstract: A method is disclosed for producing protein foods and edible oils from protein and oil containing seeds which comprises disintegrating the seeds in an oxygen-free environment, such that air is prevented from entering in and mixing with said environment, to prevent seed enzymes from producing off-flavors and bitter taste without heat treating seeds to inactivate the enzymes and concomitantly insolubilize the seed proteins. Artificial milk extracted from soybeans using this method has no-beany flavor, bitter taste, or chalkiness. Flaking of soybeans employing this method gives bland flakes without denaturing proteins. Such flakes are suitable for making highly functional palatable protein foods.

Abstract: An equipment is described to produce soymilk without the undesirable beany flavor and bitter taste of ordinary soymilk. The equipment comprises grinding soybeans totally in an aqueous medium at room temperature without trapping any air, cooking the resulting slurry, and separating the undesolved solids to extract soymilk. The fact that no heat needs to be given to soybeans prior to or during the grinding operation, yields very high percentage of solids in soybeans as dissolved solids in soymilk without rendering chalkiness found in the soymilks made employing the hot-grind and blanching methods. The equipment can also be used for making bland nutritional extracts of other protein rich seeds which are known to give rise to flavor problem in foods made from them.
