Zusammenfassung:Microcalorimetric methods have been developed for continuous analytical control of glucose, lactose and sucrose concentrations in solutions in biotechnological processes. The methods are based on the Malprade reaction. The carbohydrate concentrations were detected on a flow-mix microcalorimeter. The accuracy of measurements of the carbohydrate concentration (2–4 mM) in solution is 1–2%. Other components common to biotechnological solutions (amino acids, ammonium ions, urea and acetate) have virtually no influence on the results.
