Lactic Acid test in Egg and Egg Products

Simple chemical analysis of egg products and eggs thanks to CDR FoodLab® with very easy and quick sample preparationThe N.853/2004 REGULATION (CE) states that the level of lactic acid in egg products should not exceed 1000 mg/kg of dry matter

CDR FoodLab® is an innovative analysis system which simplifies and speeds up the procedures traditionally used allowing to determine the Lactic acid quickly: testing time 8 minutes

Check out how to test L-Lactic Acid in egg products


Test type: End point
Testing time: 8 minutes.
It is possible to carry out several test sessions with a maximum of 16 samples.

Test principle

L-Lactic acid reacts, by an enzymatic reaction, with a phenolic derivate and forms a pink colored complex. The absorbance of the complex, read at 505 nm is directly proportional to the concentration of L-lactic acid in the sample. The result is expressed in ppM.

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.

Code *300429: suitable for 100 tests

Code *300428: suitable for 20 tests 

The reagents have a shelf-life of 12 months.


Powder Egg: reconstitute the sample with distilled water.

Liquid Egg: as it is.

Measuring Range

Test Measuring Range Resolution Repeatability
Lactic acid liquid egg 5 - 4000 ppm 0.1 ppm 8 ppm
Lactic acid powder egg 100 - 6000 ppm 1 ppm 70 ppm

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.
