Method recognition:

Methods based on this principle have been accepted by MEBAK, OIV, EU, ISO2963, AOAC and IFU22 (NOTE:If the enzyme oxaloacetate decarboxylase is present in the sample, some of the oxaloacetate product is converted to pyruvate. Therefore, to ensure citric acid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employed to efficiently convert any pyruvate produced into D-lactate and NAD+).

The Citric Acid test kit is aflexible and simple method for the rapid and reliable measurement and analysis of citric acid (citrate) in foods, beverages and other materials.

Note for Content:The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave
