| Acidity in Orange Juice |
| Log #17A Titration Application Note |
| Total acidity of orange juice is determined using the first derivative titration technique. NaOH titrant is added to a volume of deionized water containing an accurately weighed 1 gram juice sample, and an Orion ROSSTM Combination pH electrode. The Orion 960 Titrator PLUS determines the endpoint and calculates the total acidity of each sample.
