Together with glucuronic acid, galacturonic acid is one of the organic acids that are developed during the fermentaiton process in kombucha beverage. Their importance is due to their detoxifying, antioxidating and digestive properties.
CDR KombuchaLab: Instruments for the determination of Galacturonic Acid in Kombucha
The instruments are supplied pre-calibrated and ready to use.
The results are expressed according to the reference method.
The methods are simple: there is no need for an equipped laboratory or for specialist personnel.
|CDR KombuchaLab Junior|
Alcohol by Volume
Total Lactic Acid
Yeast Assimilable Nitrogen (YAN)
|Configuration with tailored panel of analyses|
|Simultaneous Sample Analyses||16||3|
|Multiple Analyses on a Sample||–|
Test type: End Point.
Time testing: 4 minutes.
Are possible test sessions with several samples, up to 16 tests for CDR KombuchaLab and 3 tests for CDR KombuchaLab Junior.
Uronate dehydrogenase reacts with galacturonic and glucuronic acids to develop NADH, which is directly proportional to the sample concentration, in g / L.
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.
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 *301040: 100 tests
Code *301045: 10 tests
The reagents have a shelf-life of 6 months
Processing of Sample Volume
For precise and repeatable analysis, the sample must be degassed with the appropriate ultrasonic bath (code 222062) with the mini-centrifuge (code 222061) to separate the solid particles present in the solution.
|Galacturonic Acid [0.1-2 g/L]||0.1 - 2 g/L||0.01 g/L||0.04 g/L|
|Galacturonic Acid [0.03-0.5 g/L]||0.03 - 0.5 g/L||0.01 g/L||0.02 g/L|
