Alcohol in cider

CDR CiderLab: the analysis system for cider to perform quality and process controlsAlcohol content is the measurement of ethanol content etanolo in an alcoholic beverage. In cider constitutes an important quality parameter.

The determination of alcohol by volume with CDR CiderLab is simpler and more rapid than OIV method, OIV methods: it consists in a simple photometric reading and operates on a small sample of cider as is without any distillation.

The analysis has a high repeatibility and reliable. The results you obtain with CDR CiderLab are compliant with the results of OIV reference analytical methods.

Test Principle

Ethanol + NAD+ Test principle of alcohol analysis in wine Acetic Aldehyde + NADH
Ethanol is oxidized in an alkaline environment through an enzymatic reaction and converted in acetic aldehyde in presence of NAD+, which in turns produces NADH. The increase of the absorbance, measured at 366 nm (end-point) is directly proportional to the concentration of ethanol in the sample.

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.

Code *300603: The kit, designed for 10 dilutions (code *300605) and 10 determinations (code *300604)
Codice *300600: The kit is constituted by 10 *300603 kits and allows 100 determinations.

The reagents have a shelf-life of 6 months.

Processing – Sample Volume – Measuring Range

The analysis requests a rapid and simple dilution of the sample. The test is suitable for sweet cider as well, because it is able to measure up to 20% v/v.
