Determination of Fermentable Sugars in Fruit Juices
Measuring sugars (glucose, fructose, sucrose) in fruit juice is essential to ensure product quality, ensuring that each batch maintains the same level of sweetness, preserves a taste consistent with market expectations and respects the concentration declared on the label.
Method
Sample treatment
The sample must be centrifuged (code 222061) before the analysis. 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.
