CDR FoodLab® is the chemical analyzer for quality and process control that allows you to determine a wide range of parameters of many foods, animal feeds and pet foods.

Reducing sugar test in tomato derivatives

The analysis of Reducing Sugars (glucose and fructose) with CDR FoodLab® allows you to quickly and easily quantify the concentration of the analyte inin tomato derivatives.

Method

Test Principle

Glucose and fructose react with a complex enzyme with the consequent production of NADH. The increase in absorbance, measured at 366 nm in the end-point, is directly proportional to the concentration of the analyte.

Calibration Curve

Comparative tests, on samples of tomato performed between the reference method and the CDR FoodLab® method, made in a leading tomato production company, have confirmed a very good alignment between the two systems.
