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.

L-Lactic Acid test in Egg and Egg Products

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: non sample treatment, testing time 8 minutes.



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.

Calibration curve

CDR method shows a very good correlation with Official Method.
