Determination of Total Acidity in vinegar

The total acidity of the vinegar is the sum of its titratable acidities when it is titrated to pH 7 against a standard alkaline solution. It is a very important quality parameter for vinegar.


Test Principle

The total acidity reacts with a proper chromogen to decolorize it. The magnitude of discoloration, measured at 620 nm, is proportional to the total acidity value in the sample.


Calibration curve

The calibration curve showed a good linearity of the system on the whole measuring range, compared to reference method.
