    • Among the various aspects of the invention is a vegetable protein composition having an isoflavone content of less than 0.6 mg aglycone per gram vegetable protein, a ribonucleic acid (RNA) content of at least about 5000 mg/kg, a total inositol phosphate content measured as the sum of an inositol-6-phosphate (IP6) content, an inositol-5-phosphate (IP5) content, an inositol-4-phosphate (IP4) content, and an inositol-3-phosphate (IP3) content of less than about 8 μmol per gram vegetable protein, and less than 0.4 wt.% phytic acid based on the total weight of the vegetable protein composition. Yet another aspect of the present invention is a process for making a vegetable protein composition from a protein-containing material comprising the steps of treating a vegetable protein curd with a phytase enzyme not having protease side activity to form a phytase-treated vegetable protein material; and solubilizing and separating the phytase-treated vegetable protein material to form the vegetable protein composition. The weight ratio of an aqueous extractant to the protein-containing material for the process is from 16:1 to 70:1.
    • 在本发明的各个方面中,植物蛋白组合物的异黄酮含量小于0.6mg糖苷配基每克植物蛋白,核糖核酸(RNA)含量至少约5000mg / kg,总肌醇磷酸酯含量测定为 肌醇-6-磷酸(IP6)含量,肌醇-5-磷酸(IP5)含量,肌醇-4-磷酸(IP4)含量和肌醇-3-磷酸(IP3)含量的总和小于 约8μmol/ g植物蛋白,以及基于植物蛋白组合物总重量的小于0.4wt。%的植酸。 本发明的另一方面是从含蛋白质的材料制备植物蛋白组合物的方法,包括以不具有蛋白酶侧活性的植酸酶处理植物蛋白凝乳以形成植酸酶处理的植物蛋白材料的步骤; 并溶解并分离植酸酶处理的植物蛋白材料以形成植物蛋白组合物。 水提取剂与该方法的含蛋白质的材料的重量比为16:1至70:1。
