The Appendix to this standard contains provisions which are intended for voluntary application by commercial partners and not for application by governments.
1. SCOPE
This standard applies to olive oils and olive-pomace oils described in Section 2 presented in a state for human consumption.
2. DESCRIPTION
2.1 Olive oil is the oil obtained solely from the fruit of the olive tree (Olea europaea L), to the exclusion of oils obtained using solvents or re-esterification processes and of any mixture with oils of other kinds.
2.2 Virgin olive oil is the oil obtained from the fruit of the olive tree solely by mechanical or other physical means under conditions, particularly thermal conditions, that do not lead to alterations in the oil, and which has not undergone any treatment other than washing, decanting, centrifuging and filtration.
2.3 Olive-pomace oil is the oil obtained by treating olive pomace with solvents, to the exclusion of oils obtained by re-esterification processes and of any mixture with oils of other kinds.
3. ESSENTIAL COMPOSITION AND QUALITY FACTORS
