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.

Colour of the Egg and Egg Products

The 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.
