Rheological properties (acidity) for olive oil in Palestine

A.M.Bahti, Sh.M.Musameh, I.R.Abdelraziq

In this study, olive oil samples of different storage ages and locations in Palestine were studied. The acidityof the samples was measured. The acidity of olive oil samples from different regionsand different crops showed that acidity increases as a function of storage age. Most of olive oil samples (storage age d” 12 years) acidity did not exceed the international quality standards (< 3.3%). It is worth noting that olive oil can be stored until 12 years without exceeding the international quality standards of acidity in proper conditions.
