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.

Sugars analysis on Potatoes

Glucose and fructose are the most important sugars to analyze in tubers both as a qualitative parameter and as a process control. These sugars can be precursors of acrylamide in frying products; knowing their value on potatoes, before being processed, allows to avoid problems during cooking. The glucose and fructose content can be determined together (kit codes *300380 and *300384) or separately (kit codes *300335 and *300355).

Method

Test type: End Point.

Testing time: 4 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

Mix the sample to obtain a homogeneous pulp. Carry out a 1:1 dilution of the sample with distilled water and add 70% perchloric acid in these proportions: 100g of potato + 100g of water + 0.6 ml of perchloric acid. Centrifuge for 5 minutes at 12000 rpm. Collect the supernatant for analysis.

Principle of the test

The fructose and glucose present in the sample are determined enzymatically. 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.
