摘要： A method for recovering amino acids, which comprises supplying a mixed solution containing inorganic acid salts, amino acids and non-electrolytes such as saccharides to a first-step resin layer comprising an Na type or K type strongly acidic ion exchange resin; separating an effluent into at least a first fraction containing coloring matters, acidic amino acids and ashes, a second fraction containing neutral amino acids and saccharides, and a third fraction containing betaines; supplying the second fraction to a second-step resin layer comprising at least one resin selected from the group consisting of NH 4 type, Ca type and Mg type strongly acidic ion exchange resins, and optionally further supplying it to a third-step resin layer comprising an Mg type or Ca type strongly acidic ion exchange resin different from the resin of the second-step resin layer, thereby recovering various kinds of amino acids contained in an effluent.
