Flexible, rapid and simple method for the measurement of citric acid in foods, beverages and other materials

Shipping temperature: ambient

Storage temperature:
- Short term stability: 2-8^oC,
- Long term stability: see individual component labels

Assay format: spectrophotometer, microplate, auto-analyser

Detection method: absorbance - 340

Signal response: decrease

Linear range: 1,0 to 100 µg of citric acid per assay

Reaction time: 5 minutes

Detection limit: 0,491 mg/l

Method recognition: method 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+.
