Betalyser is an automated laboratory system for the quality control and analysis of sugar beet according to official ICUMSA methods. The polarimetrically determined sugar content alone is not sufficient for the calculation of the expected sugar yield, as molasses-forming beet ingredients like potassium, sodium, and a-amino nitrogen have to be considered. The Betalyser system is the ideal tool for analyzing clarified extracted sugar beet brei filtrates on sugar content and the molasses-forming ingredients.
