Olive oil is an important food product, especially
in Mediterranean countries, and its characterisation
is an issue of current interest. At present, there is no
single analytical index for characterising it, and
numerous physical and chemical parameters (such
as free acidity, peroxide value, K232 and K270 among
others) must be measured to determine its
geographical origin and/or olive variety (Aparicio,
1988; Tous et al., 1997; Lanteri et al., 2002; Marini et
al., 2004)
