ELECTRODIALYSIS METHODS FOR PURIFICATION AND RECOVERY OF GLUCONIC ACID DERIVATIVES

A process for purifying and concentrating a gluconic acid derivative, such a s 2-keto-L-gulonic acid, comprising introducing a non-viable and/or acidified fermentation medium or an in-vitro reactor medium comprising at least the gluconic acid derivative and/or salt thereof to electrodialysis thereby...
