Lactic Acid test in Egg and Egg Products
CDR FoodLab® Touch is an innovative analysis system which simplifies and speeds up the procedures traditionally used allowing to determine the Lactic acid quickly: 5 minutes for sample preparation, testing time 8 minutes. The sample can also be used for the determination of D-3-hydroxybutyric acid: it’s possible to perform both tests on the same sample with a considerable saving of time.

Test type: End point
Testing time: 8 minutes.
It is possible to carry out several test sessions with a maximum of 16 samples.
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 *300385: suitable for 100 tests
Code *300388: suitable for 20 tests
The reagents have a shelf-life of 12 months.
Processing – Sample Volume – Measuring Range
Powdered egg, mixed egg and egg white, yolk diluited. Transfer part of the solution obtained in a centrifuge tube and centrifuge for 5 min
It ‘s possible to test both Lactic and D-3-hydroxybutyric acid on the sample prepared.
