Reactive extraction of amino acids mixture in hydrolysate from cottonseed meal with di(2‐ethylhexyl) phosphoric acid

BACKGROUND: In recent years there has been a noticeable growth of amino acid utilization throughout the world. How to separate and purify amino acids from fermentation broths or protein hydrolysates in an effective and low cost way is increasingly becoming an urgent problem. The utilization of solve...

Description
Summary:BACKGROUND: In recent years there has been a noticeable growth of amino acid utilization throughout the world. How to separate and purify amino acids from fermentation broths or protein hydrolysates in an effective and low cost way is increasingly becoming an urgent problem. The utilization of solvent extraction technology for amino acids separation offers one solution. RESULTS: Extractions of individual amino acids in aqueous solution with di(2‐ethyl‐hexyl)phosphoric acid (D2EPHA) are dominated by aqueous pH and their hydrophobicity. The degree of extraction of amino acids increases with increasing pH (1.0
