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

Determination of the Acetic acid in cider

Acetic acid, often referred to volatile acidity, can be produced by several yeasts and bacteria present in cider. It may form during fermentation, secondary product, or during storage due to the deterioration of finished cider.

Method

Test Principle

Through an enzymatic reaction, acetic acid is converted into piruvic acid, which reacts with NADH producing NAD+ and D-Lactic acid. The reduction of absorbance, measured at 366 nm (end-point), of the NADH solution is proportional to the quantity of acetic acid present in the sample.
