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.
L-Lysine is one of the essential amino acids, which cannot be synthesized in the body. The main application of Lysine is animal feed. The global market for food-grade L-Lysine is estimated at over 800,000 ton (2007 figure). The market price for bulk Lysine has dropped significantly over the past decade(s), forcing suppliers to apply more efficient manufacturing technologies.
