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 and its derivatives

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

Method

Test type: End Point.

Time testing: 6 minutes.

Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR FoodLab® and 3 tests for CDR FoodLab® Junior.

Sample treatment

Filter the sample before analysing.

Principle of the test

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.
