Polyphenols are the natural antioxidant compounds that give extra virgin olive oil much of its flavour, stability and health interest. Under EU law, an olive oil can carry the authorised claim that “olive oil polyphenols contribute to the protection of blood lipids from oxidative stress” — but only if it contains at least 5 mg of hydroxytyrosol and its derivatives per 20 g of oil (Regulation (EU) 432/2012). For a brand, high-polyphenol oil is a credible, regulated way to stand out.
What polyphenols are and why they matter
- Antioxidants — hydroxytyrosol, tyrosol, oleocanthal and oleuropein derivatives.
- Taste — they create the peppery, slightly bitter notes of a fresh EVOO.
- Stability — higher polyphenols generally mean a longer shelf life.
- Regulated claim — the EU antioxidant claim is allowed above the 5 mg/20 g threshold.
What drives polyphenol content
| Factor | Effect on polyphenols |
|---|---|
| Variety | Picual and early-harvest oils are typically highest |
| Harvest timing | Earlier (green) harvest = more polyphenols |
| Extraction | Cold extraction preserves them |
| Freshness & storage | Polyphenols decline over time and with heat/light |
High-polyphenol oil as a private label positioning
If health is your angle, an early-harvest Picual can be measured and, above the legal threshold, labelled with the EU antioxidant claim — a strong, compliant differentiator for premium retail and export. We source, measure and bottle to that specification. See our olive oil sourcing, our turnkey service, and the private label guide.
Frequently asked questions
Which olive oil has the most polyphenols?
Early-harvest, cold-extracted extra virgin oils from robust varieties such as Picual tend to be highest. Exact levels are confirmed by laboratory analysis.
Can I put a health claim on my label?
Only the specific EU-authorised claim, and only if the oil contains at least 5 mg hydroxytyrosol and derivatives per 20 g, verified by analysis. We help you meet and document the threshold.
Do polyphenols affect taste?
Yes — they create the peppery, bitter, “throat-catching” notes typical of a fresh, high-quality EVOO.
Can you provide polyphenol analysis?
Yes. Technical and organoleptic analyses, including polyphenol content, can be provided on request.
