CDR CiderLab the easy-to-use analysis system to optimise your cider production process by obtaining results in real time.

Determination of Citric acid in cider

Citric acid is an organic acid found in fruit and fruit juices used in cider production. It can also be formed by yeasts during fermentation and, therefore, measuring it can be an important indication for the producer.


Test principle

Through an enzymatic reaction, citric acid is converted into oxalacetate and then into malate that reacts with NADH producing NAD+. The reduction of absorbance, measured at 366 nm (end-point), of the NADH solution is proportional to the quantity of citric acid present in the sample.
