The Ethanol (Liquid Ready) assay kit is a rapid (~5 min), method for the specific measurement and analysis of ethanol in wine, beverages, foodstuffs and other materials. Supplied as a “ready to use” liquid stable formulation that is suitable for manual auto-analyser and microplate formats and is simple, reliable and accurate.
Suitable for manual, auto-analyser and microplate formats.
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 Spectrophotometer (D-MQWAVE).

Determination of ethanol concentration in Kombucha beverages: Single-laboratory validation of an enzymatic method, First Action Method 2019.08.
Ivory, R., Delaney, E., Mangan & McCleary, B. V. (2020). Journal of AOAC International, qsaa122.
The Ethanol Assay Kit is an enzymatic test kit developed by Megazyme for the determination of ethanol in a variety of samples. The kit has been validated in a single laboratory for use with Kombucha fermented drinks, fruit juices and low-alcohol beer samples. The commercially available Ethanol Assay Kit (Megazyme catalogue no. K-ETOH) contains all components required for the analysis. Quantification is based on the oxidation of ethanol to acetaldehyde by alcohol dehydrogenase and further oxidation of acetaldehyde by acetaldehyde dehydrogenase with conversion of NAD+ to NADH. The single laboratory validation (SLV) outlined in this document was performed on a sample set of eight different commercial Kombucha products purchased in Ireland, a set of five Cerilliant aqueous ethanol solutions, two BCR low-alcohol beer reference materials, two alcohol-free beer samples and two fruit juice samples against SMPR 2016.001 (1). Parameters examined during the validation included Working range, Selectivity, Limit of Detection (LOD), Limit of Quantification (LOQ), Trueness (bias), Precision (reproducibility and repeatability), Robustness and Stability.
