Kombucha

Kombucha is a fermented beverage obtained from tea and added sugars (mainly sucrose). It is advisable to check the evolution of the fermentation process, promoted by the symbiosis of bacteria and yeasts used to produce it, in order to be able to stop it once the optimal sugar level has been reached which allows the desired taste and organoleptic characteristics to be obtained. Furthermore, the analysis of sugars allows the prompt recognition of a possible fermentation arrest.

Determination of Fermentable Sugars in Kombucha

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

Test type: End Point. Time testing: [uni] Analysis sessions with multiple samples are possible for up to a maximum of 16 tests for CDR KombuchaLab and 3 tests for CDR KombuchaLab Junior.<h3>Sample treatment</h3>For precise and repeatable analysis, degas the sample using the ultrasonic bath (code 222062) and clarify it, if necessary, using the centrifuge (code 222061). Dilute the sample with the included dilution kit, as required by the method.

Method

Fermentable sugars (glucose, fructose and sucrose) in the presence of NAD+ react with glucose oxidase, developing NADH. The concentration expressed in g/L is determined through the stoichiometric ratio 1:1 with the total quantity of sample sugars.

Test Principle

The calibration curve of the CDR KombuchaLab &nbsp;instrument, obtained by comparing the CDR method with the enzymatic method for the determination of glucose, fructose and sucrose, confirmed an excellent linearity of the system over the entire measurement range.
