AbstractStability of olive oil during shelf-life depends on several factors, such as cultivar, technology, and storage conditions. In this research the influence of different processing parameters and of packaging and storage conditions on some quality parameters was
studied, in order to evaluate the shelf-life of a mono-varietal oil. The oil samples have
been extracted with a two-phase decanter from whole or destoned olives, and with a
three-phase decanter from whole olives (Bosana cv.). The oils have been hermetically
packaged in glass bottles, half of them with a 3 mL headspace, and the other half filled
up. Containers have been stored at ambient temperature and under diffused light or in
the dark. Data show that oil degradation is not always affected by storage conditions.
Moreover, due to the very high original content in antioxidants, the oil keeps its high
quality characteristics.
