D-Fructose/D-Glucose test kit, an enzymatic UV-method for the measurement and analysis of D-fructose and/or D-glucose in plant and food products.

Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.

UV-method for the determination of D-Fructose and D-Glucose 
in foodstuffs, beverages and other materials

Principle:
                        (hexokinase)
(1) D-Glucose + ATP → G-6-P + ADP

                         (hexokinase)
(2) D-Fructose + ATP → F-6-P + ADP

          (glucose-6-phosphate dehydrogenase)
(3) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+

    (phosphoglucose isomerase)
(4) F-6-P             ↔             G-6-P

Kit size:                            110 assays (manual) / 1100 (microplate)
                                          / 1100 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 13 min
Detection limit:                 0.66 mg/L
Application examples:
Wine, beer, fruit juices, soft drinks, milk, jam, honey, dietetic foods,
bread, bakery products, candies, desserts, confectionery, ice-cream,
fruit and vegetables, condiments, tobacco, cosmetics, pharmaceuticals,
