    • Soybean proteins are manufactured from soybean protein concentrates. The soybean protein concentrates may be prepared by washing defatted soybean with an alcoholic aqueous solution. The soybean protein concentrates are dispersed in water and then adjusted to a neutral to slightly alkaline pH range or dispersed in an aqueous solution which was previously adjusted with ammonia to be in an alkaline pH range, thus providing a neutral to slightly alkaline aqueous dispersion. The afore-mentioned soybean proteins in this aqueous dispersion are solubilized by the action of a neutral protease. The insolubles in the aqueous dispersion thus prepared are then removed to produce an aqueous solution containing solubilized proteins from which solid proteins are recovered.
    • 大豆蛋白质由大豆蛋白浓缩物制成。 大豆蛋白浓缩物可以通过用醇水溶液洗涤脱脂大豆来制备。 将大豆蛋白浓缩物分散在水中,然后调节至中性至微碱性pH范围,或分散在预先用氨调节至碱性pH范围的水溶液中,从而提供中性至微碱性水性分散体。 这种水性分散体中的上述大豆蛋白质通过中性蛋白酶的作用而溶解。 然后除去如此制备的水分散体中的不溶物,以产生含有溶解的蛋白质的水溶液,从中回收固体蛋白质。
