APPENDIX IV. DRAFT REVISED STANDARD FOR OLIVE OILS AND OLIVE POMACE OILS

(At Step 6 of the Procedure)

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

3.1 Extra virgin olive oil: virgin olive oil with a free acidity, expressed as oleic acid, of not more than 1 gram per 100 grams and the organoleptic characteristics corresponding to those laid down for this category in section 3.8.

3.2 Virgin olive oil: virgin olive oil with a free acidity, expressed as oleic acid, of not more than 2.0 grams per 100 grams and the organoleptic characteristics corresponding to those laid down for this category in section 3.8.

3.3 Ordinary virgin olive oil: virgin olive oil with a free acidity, expressed as oleic acid, of not more than 3.3 grams per 100 grams and the organoleptic characteristics corresponding to those laid down for this category in section 3.8.[16]

3.4 Refined olive oil is the olive oil obtained from virgin olive oils by refining methods which do not lead to alterations in the initial glyceridic structure. It has a free acidity, expressed as oleic acid, of not more than 0.3 grams per 100 grams.

3.5 Olive oil, marketed as such, is the oil consisting of a blend of refined olive oil and virgin olive oil, as identified in section 2 and meeting the requirements identified in section 3.1, 3.2 and 3.3. It has a free acidity, expressed as oleic acid, of not more than 1.5 grams per 100 grams.

3.6 Refined olive-pomace oil: obtained from crude olive-pomace oil by refining methods which do not lead to alterations in the initial glyceridic structure. It is intended for use either as it is or else in blends with virgin olive oil, as identified in section 2 and meeting the requirements identified in section 3.1, 3.2 and 3.3. It has a free acidity, expressed as oleic acid, of not more than 0.3 grams per 100 grams.

3.7 Olive-pomace oil: blend of refined olive-pomace oil and virgin olive oil, as identified in section 2 and meeting the requirements identified in section 3.1, 3.2 and 3.3. It has a free acidity, expressed as oleic acid, of not more than 1.5 grams per 100 grams.
