A method for the production of purified proteins with controlled isoflavones content is disclosed. The method includes providing a plant material containing at least one protein, at least one sugar and at least one isoflavone in a malonyl glycoside form. The method also includes hydrolyzing at least part of the at least one isoflavone in malonyl glycoside form to generate isoflavone in glycoside or aglycones form. The method also includes solubilizing at least part of the at least one sugar to form at least one solubilized sugar. The method also includes separating the at least one solubilized sugar while at about pH less than 10 to form an isoflavone-containing purified protein stream and a sugar-containing stream. A purified protein from a soy-based starting material is also disclosed. The purified protein has a protein concentration of at least about 60 percent. The purified protein is characterized by at least one of: (1) being substantially free of isoflavones in malonyl glycoside form; (2) having a higher concentration of isoflavones content in glycoside or aglycones form relative to the soy-based starting material; (3) being substantially free of an anti-nutritional factor.
