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.
