High pH recovery of neutral amino acids |
| abstract |
Neutral amino acids can be recovered from an aqueous solution by the steps of:n 1) forming a concentrated solution of said amino acid which solution has a pH above the solution pKa of the acid 2) removing base uniformly from the solution so as to form solid particles of the neutral amino acid at a pH above the solution pKa of the neutral amino acid. 3) recovering said solid particles from the solution. This method provides a product that is highly pure without the need for organic solvents. In a preferred embodiment, the solution is first concentrated and then filtered at high pH. This high pH filtration avoids the need for conventional ion exchange treatments. |
