Ketogluconic, lactic, citric, succinic and many other organic acids are products that rely on a platform manufacturing technology. This means that most modern manufacturing facilities apply – to a large degree – the same processes. In both cases, the key step in the production process involves a fermentation followed by purification of products using at least one ion exchange step.
Application of a continuous countercurrent ion exchange technology for purification of these products result in significant advantages. In this memorandum, the effect of continuous ion exchange technology on purification of ascorbic acid will be elucidated.
