Colour of the Egg and Egg Products

Simple chemical analysis of egg products and eggs thanks to CDR FoodLab with very easy and quick sample preparationThe colour is an important quality control parameter for eggs. It allows to determine the category of the eggs and eggproducts. The test is based on the photometric reading of the absorbance of the beta-carotene, a pigment naturally present in eggs.

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 beta-carotene.

Calibration Curve

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

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
