Analysis of Xanthophylls

Simple chemical analysis of egg products and eggs thanks to CDR FoodLab with very easy and quick sample preparationXanthophylls are natural pigments added in poultry feed in order to set the colour of the future egg product. The test allows to determine the value of the xanthophylls with an advantageous method and with a minimum waste of food matrix.

CDR FoodLab®  simplifies and speeds up the traditionally used procedures enabling to perform many analyses, in few time and with small quantities of sample as is.

Test principle

The test is based on the photometric reading of the absorbance of the xanthophylls.

Calibration Curve

CDR FoodLab® method shows a very good correlation with the reference method.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
