Isomerization is a chemical process of transformation of a molecule into its isomeric form. The new molecule has the same chemical composition but the atoms are arranged in a different way, resulting in different physical and chemical properties.
Isomerization is applied by Vogelbusch for the conversion of glucose into fructose to increase the sweetness of the product. The resulting isoglucose syrup is further processed to commercial high fructose syrups.
The process is designed using immobilized enzymes in a set of parallel operated fixed bed reactors. In consideration of the aging of the enzymes, process parameters (flow, temperature) are adjusted for each reactor to ensure stable syrup properties at a constant feed rate to the system. Maximizing productivity and lifetime of the enzymes is achieved by appropriate treatment of the feed stream.
„Our expectations have been totally satisfied. It's been three years working at full capacity and we are very pleased with the work done on this plant."Lic. Adrián Urquía, Promaiz S. A., Bioethanol Plant, Alejandro Roca, Cordoba, Argentina
