Test Eggs for L-lactic Acid and Butyric Acid
The CDR FoodLab tests freshness and quality
Rapid L-lactic acid and butyric acid tests on eggs
Determine shelf life of baked products
Test egg colour and cholesterol
Validated alternative to reference or titration methods
Eggs Quality Control
The CDR FoodLab provides quick and easy measurement of the quality of eggs, determining multiple parameters such as butyric acid, an indicator of fertilised eggs, and lactic acid, an indicator of freshness. Simple to use, the software guides the user step by step through the egg test methods and pre-filled reagent vials simplify sample preparation. Tests are completed in a few minutes, facilitating real time process adjustments and improving quality control. The CDR FoodLab is used to measure the lactic and 3-hydroxybutyric acid levels in eggs used in food products
Parameters: L-Lactic Acid, D-3-hydroxybutyric Acid, Total Acidity, Cholesterol, Colour, Xanthophylls
Automated microbiology tests for liquid and frozen egg are also available of the BacTrac 4300.

Egg Tests
Acidity
In some preparations for food products containing eggs, some specific enzymes are added in order to free the fatty acids. The total acidity test allows to check the total quantity of acidity and to monitor the enzymatic reaction. This test allows to check the acid content of the egg products in order to control the hydrolase activity.
Lactic Acid
The verify of the hygienic condition of the eggs used in the preparation of egg products, is based on the analysis of indicators of microbial metabolism such as lactic acid. The total bacterial count is not a suitable index because it is reduced by the pasteurization treatment. To ensure that the handling of eggs and egg products is made in respect of the rules of hygiene, the regulation (EC) No 853/2004 states that the lactic
acid content must not be greater than 1000 mg / kg of dry matter.
Cholesterol
The average content of cholesterol in eggs is constant. Therefore, it is possible to use this test to determine the amount of eggs contained in a specific food preparation.
D-3-Hydroxybutyric Acid
The pasteurization of egg products is based on the use of not high temperatures, because egg proteins are sensitivity to heat. For this reason, the use of bad eggs, increases the health risk and reduces the shelf-life of the fresh egg products. The use of incubated or decayed eggs can be detected verifying the presence of some organic acids indicative of metabolic products and microbial decomposition such as succinic acid, lactic acid and D-3-hydroxybutyric acid. The best method currently highlighting this fraud is the test of D-3-hydroxybutyric acid, very low in fresh eggs (<1mg/kg), but much higher in incubated or decayed eggs. The N.853/2004 regulation (CE) states that the level of D-3-hydroxybutyric acid in egg products should not exceed 10mg/kg of dry matter. The analysis is usually carried out by extraction and gas chromatography.
Colour
The colour is an important quality control parameter for the egg which allows to determine the category of the egg-product.
How It Works
Features
Innovative Technology
The use of innovative photometric technology means the reading cell guarantees high sensitivity, a very wide measuring range and excellent repeatability of the analysis results thanks to innovative LED light sources with fixed wavelengths (ultraviolet – visible spectrum, power up to 6 O.D.).
Online Help
The system is easy and intuitive, everyone can use it. Analyses are carried out in just a few steps. In addition, it has a help function that guides you step by step through the test procedures.
Multitasking Mode
The multitasking mode reduces analysis time by making it possible to perform several analyses of the same sample simultaneously, or different determinations of the same parameter on a batch of different samples. During an analysis session you can start another one and put the first one in the background. You can return to background analysis with one click.
Internal Memory
The analyser is equipped with an internal memory capable of storing thousands of analysis results that can be viewed on the display or exported via the USB or Ethernet port.
Barcode/QR Code Reader
The analyser connects with barcode or QR code readers. The sample code is automatically displayed on the analyser. It is possible to associate all the analyses performed on that sample.
PC/Intranet Connection
You can share analysis results by connecting the analyser to your intranet via the Ethernet port or export them by connecting the analyser via the USB port to a host computer.
Maintenance/Service Free
No calibration is necessary because the instrument is supplied pre-calibrated. The analysers use LED light sources and therefore no periodic maintenance is required.
