Determination of Glycerol in Kombucha
Glycerol is a substance produced by yeasts during alcoholic fermentation. In Kombucha this compound, based on its concentration, can determine a consistent effect on the organoleptic characteristics. The determination of its concentration in the finished product and above all its monitoring during fermentation constitute a fundamental aspect of quality control during the production process.
Method
Test Principle
Glycerol, in the presence of an enzyme and a suitable chromogen, reacts causing the formation of a pink colour. Absorbance at a wavelength of 505 nm is proportional to the concentration of glycerol in the sample.

Calibration Curve
The calibration curve of the CDR KombuchaLab, obtained by comparing the CDR method with the enzymatic method for the determination of glycerol in Kombucha, confirmed excellent linearity of the system over the entire measurement range.
