    • Disclosed is a process comprising: mixing a soy protein-containing material with an aqueous medium; removing the non-solubilized solids from the slurry to form an alkaline liquid containing solubilized soy protein; adjusting the pH of the solubilized soy protein liquid to between about 3.8 and about 6.6, to precipitate soy protein from the liquid; separating the precipitated soy protein from the pH-adjusted soy protein liquid; resolubilizing the separated soy protein precipitate in an aqueous medium at a pH of from about 1.8 to 3.2; treating the resolubilized soy protein with at least one water-soluble calcium salt to form a calcium-enriched soy protein mixture; precipitating soy protein from the calcium-enriched soy protein mixture by adjusting the pH of the mixture to between about 3.8 and about 6.6; separating the precipitated soy protein from the calcium-enriched soy protein mixture; and washing to form calcium-enriched soy protein isolate having selectively reduced manganese concentrations.
    • 公开了一种方法,其包括:将含大豆蛋白的材料与水性介质混合; 从浆液中除去未溶解的固体以形成含有溶解大豆蛋白的碱性液体; 将溶解的大豆蛋白液体的pH调节至约3.8至约6.6,以从液体中沉淀大豆蛋白; 将沉淀的大豆蛋白与pH调节的大豆蛋白液体分离; 将分离的大豆蛋白沉淀物在约1.8至3.2的pH下在水性介质中重新溶解; 用至少一种水溶性钙盐处理所述再溶解的大豆蛋白以形成富含钙的大豆蛋白混合物; 通过将混合物的pH调节至约3.8至约6.6,从富钙大豆蛋白混合物中沉淀大豆蛋白; 将沉淀的大豆蛋白与富钙大豆蛋白混合物分离; 并洗涤以形成具有选择性还原的锰浓度的富钙大豆蛋白分离物。
