Determination of Galacturonic Acid in Kombucha

Together with glucuronic acid, galacturonic acid is one of the organic acids that are developed during the fermentation process in kombucha beverage. Their importance is due to their detoxifying, antioxidating and digestive properties.

Method

Sample treatment

For precise and repeatable analysis, degas the sample using the ultrasonic bath (code 222062) and clarify it, if necessary, using the centrifuge (code 222061).

Principle of the test

Uronate dehydrogenase reacts with galacturonic and glucuronic acid to develop NADH, which is directly proportional to the concentration in the sample expressed in g/L.

Calibration curve

The calibration curve of the CDR KombuchaLab, performed using standards with a known concentration of galacturonic acid, confirmed an excellent linearity of the system over the entire measurement range.
