Intended Use

For the quantitative in vitro determination of Glucose/Fructose in wine, beer, and fruit juices. This product is suitable for both manual and automated use.

Clinical Significance

Sugars play a key role in the wine making process. Glucose and fructose are found in honey, sweet fruits and vegetables. Fructose is sweeter than glucose and is used in the production of many diet foods. Glucose with fructose is one of the two principle sugars of sweet wines and is an important indicator of grape ripening. Glucose is high during ripening and fructose high in over ripe grapes. Two in one kit: the dual kit enables the determination of both glucose and fructose.


UV method. Glucose is measured enzymatically utilizing both hexokinase and glucose - 6- phosphate dehydrogenase. The total sugar content (glucose + fructose) is determined by converting the fructose - 6- phosphate (F-6-P) to glucose-6-phosphate (G-6-P) by phosphoglucose isomerase (PGI). The G-6-P is then converted to gluconate-6-phosphate and the NADH formed is stoichiometric with the amount of total sugars.

Fructose content = Total sugar - glucose content.
