ABSTRACT:
Disclosed is a process for recovery of amino acids from aqueous mixtures. In particular, it relates to a treatment of said amino acid containing aqueous mixture prior to extraction of the amino acid with a water immiscible organic solution containing a water insoluble extractant for said amino acid. The overall process of the invention which includes the pretreatment and extraction, also includes optional methods of recovering said extracted amino acid from the water immiscible organic solution. Accordingly, the invention also relates to a process for recovery of the amino acid by stripping of the amino acid from the organic solution and precipitation of the amino acid.
