The pH of the mango juice was measured using hand digital pH
metre (Eutech,Japan), precalibrated with buffers of pH 4.0 and 7.0.
The TA of the juice was measured by titrating with 0.1 N NaOH
previously standardized using standard oxalic acid and the results
were expressed as percentage of citric acid.The TSS in the juice
were determined with a hand digital refractometer(0–30) (Erma,
Japan) at 20 °C. The instrument was calibrated with distilled water
before the analysis.TSS values were expressed as °Brix (Naresh
et al.,2014b).
