Determination of Sugars in Soft Drinks
Measuring sugars (glucose, fructose, and sucrose) in soft drinks is essential to ensure product quality, guaranteeing that each batch maintains the same level of sweetness, preserves a taste consistent with market expectations, and complies with the concentration stated on the label.
Method
Sample treatment
Degas using the ultrasonic bath (code 222062) before taking the sample. Dilute the sample with the included dilution kit, as required by the method.
Principle of the test
The glucose and fructose present in the sample are determined enzymatically and therefore are not influenced by the presence of the remaining reducing sugars. The redox reaction is read at 366 nm (end-point) and the value is directly proportional to the concentration of glucose and fructose in the sample.
