Preferred Abstract (Original):
The
acidity of olive oil samples from different locations and of different
storage ages was measured on a yearly and weekly basis. In this work,
the overall results of olive oil acidity as a function of storage age on
a yearly basis indicate deterioration of oil quality. The acidity
results for some olive oil samples suggest that the oil can be stored
for a period of not more than 12 years without deterioration. The
overall results from measuring on a weekly basis indicate that the
acidity increases incrementally as a function of storage age. The
relationships between the acidity and storage age were described by
fitting the data to equations.
