Production of amino acids from amino acid salts.
Electrodialysis is used to remove NaCl from the mother liquid for separation of Amino acids. This not only increases the yield of Amino acid but also reduces the cost of waste water treatment & disposal. Since Amino acids are amphoteric electrolytes having carboxylic acid and amino groups in the molecule, their loss during Electrodialysis can be minimised by adjusting the pH value of the feed to the iso-electric point of the amino acid. Desalination of Phenylananine, Amino Glycerin, Threonine, Lysine, 4-Hydroxy Butyrate, Hydroxyphenylglycine, Amino Butyric Acid, Tryptophan, Arginine, Glutamine, Glutamate, Glycine, Cystine, Leucine, Aspartame, Fumarate, Serine and so on.
Threonine desalination:
The Original process using ion exchange resins is replaced by Electrodialysis. The feed material contains about 2%-3% salt, suspended solids, proteins and saccharides. Ultrafiltration prior to ED is recommended.
Phenylananine desalination:
The Original process using ion exchange resins is replaced by Electrodialysis. The feed material contains about 2%-3% Phenylananine, about 2.5% inorganic salt, proteins and pigments.
