Determination of Total Acidity in Cider
With CDR CiderLab, is possible to carry out the analysis of Total Acidity with a simple photometric reading of a sample of cider dispensed in a pre-filled test tube with the appropriate reagent.
There is no need to resort to titration as required by the reference method. The results are correlated with those of the reference method.
Method
Test principle
The total acidity reacts with a proper chromogen to decolorize it. The magnitude of discoloration, measured at 578 nm, is proportional to the total acidity value in the sample.

Calibration curve
The calibration curve of CDR CiderLab, obtained using reference methods, confirms the excellent linearity of the system over the whole testing range.
