The 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
Method
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.
Processing
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 |
