A measure used in assessing the quality and condition of olive oil.
COI/T.20/DOC.34/Rev.1–2017Good oil should be able to show its work.
Gaia Iluka publishes the evidence: independent laboratory analysis, the certifications the producer holds, and the documents behind both.
What follows is what the paperwork says — no more than that.
- Koumeika · Samos
- IOC-recognised laboratory
- ISO 22000 · ISO 14001
Quality should not rest on what a label says.
Three kinds of evidence sit behind Gaia Iluka, and they prove different things. Keeping them apart is the honest way to show them.
- Tested
- A laboratory measures the oil and reports numbers. Those numbers describe the sample examined, on the date it was examined.
- Certified
- An assessment body audits a management system and issues a certificate with a defined scope and a validity period.
- Traceable
- Registration and process documentation record who the producer is, where they are, and how the oil is handled.
Two numbers worth understanding.
From the most recent analysis of the oil, carried out by an independent laboratory in Athens.
An indicator used to assess oxidation in olive oil.
COI/T.20/DOC.35/Rev.1–2017Certificate Π-133651, issued 7 April 2026 by Multichrom.LAB, Athens — recognised by the International Olive Council for physicochemical testing (Type B). Sample ΔΕΞ 11. The limits shown are those printed on the report; the report states they are given for the reader's convenience and do not constitute a declaration of conformity. Results concern only the sample examined.

Analyses by Multichrom.LAB, Athens, recognised by the International Olive Council for physicochemical testing (Type B). Each report states that its results concern only the sample examined.
What is certified, and exactly how far it reaches.
The producer holds two management-system certifications. Each covers a defined scope — worth reading, because they are not the same.
ISO 22000:2018
Food safety management system- Production
- Packaging
- Distribution
ISO 14001:2015
Environmental management system- Packaging
- Distribution
This certificate does not cover production.
Certificates issued to I.P. Markou & Co, Koumeika, Samos. Neither certifies the oil's category: the classification of extra virgin olive oil is not covered by either standard.

Bottling

Harvest, milling, storage and bottling follow the producer's technical production protocol, which sets out how the oil is made rather than recording a single harvest. Laboratory samples are drawn at the mill and identified by tank; Gaia Iluka does not currently offer batch tracing from an individual bottle.

Registrations and documentation
Registrations record that a business is entered on an official register. They are not certifications of product quality and are listed separately for that reason.
