Preferred Abstract (Original): 

The dynamic viscosity of olive oil samples of different storage ages in yearly basis from different locations was measured  as a function of temperature. In this study, the overall results of the effect of dynamic viscosity as a function of storage age  in yearly basis indicate a decrease of dynamic viscosity. This work propose three and multi-constant formulas to obtain  more suitable prediction of temperature dependence of dynamic viscosity of olive oil samples from different locations in  Palestine. The best AAD% was calculated using our proposed formulas to be 0%. The relationships between the viscosity  of olive oil samples with temperature and storage age have been found by fitting equations.

Storage Age Dependence of Olive Oil Acidity in Different Locations in Palestine

Preferred Abstract (Original): 
The acidity of olive oil samples of different locations and different storage ages in yearly and weekly basis was measured. In this work, the overall results of the effect of acidity as a function of storage age in yearly basis indicate a deterioration of oil quality. The acidity results for some olive oil samples suggest that the oil can be stored for a period not more than 12 years without deterioration. The overall results of weekly basis of this study indicate that the acidity increased incrementally as a function of storage age. The relationships between the acidity with storage age have been found by fitting equations.

Preferred Abstract (Original): 

The dynamic viscosity of olive oil samples of different storage ages in weekly basis from different locations was measured as a function of temperature. In this study, the dynamic viscosity as a function of storage age in weekly basis decreases with increasing temperatures. Three and multi-constant formulas were proposed to obtain more suitable prediction of temperature dependence of dynamic viscosity of olive oil samples. The best AAD% was calculated using our proposed formulas to be 0%.
