Method of removing isoflavones and phytates

摘要

Methods for sequentially removing isoflavones and phytates from an active surface by utilizing an aqueous medium for isoflavone removal and an aqueous medium for phytate removal. The aqueous medium for isoflavone removal contains at least one alcohol and at least one acid. The aqueous medium for phytate removal is either a relatively stronger acidic solution, a basic solution, or with some active surfaces may be an aqueous solution of pH 2-7, which is essentially free of alcohol and organic solvents. The use of the methods disclosed allows sequential isolation of isoflavones and phytates, compounds which may then be utilized in various foods for human consumption.
