Deliba Olive Oil Lab Reports & Polyphenol Results
Deliba publishes third-party test reports for its current extra virgin olive oils from Molochio, Calabria, Southern Italy. The 2025 results identify the tested lot, analysis date, total polyphenols, free acidity, peroxide value, K232, K270 and Delta K. The same facts are reproduced below in readable HTML and linked to the original PDF reports.
Last reviewed July 14, 2026 by Gianfranco Cosmano, Deliba founder and olive oil producer.
Why lot-level lab reports matter
“High polyphenol” is a measurable product characteristic, not a substitute for evidence. A dated report tied to a specific lot makes quality claims more verifiable and allows customers to compare results within the same harvest and testing method.
If you’re comparing extra virgin olive oils by measured composition and taste, this is the evidence you should expect.
What to check in an olive oil lab report
A useful extra virgin olive oil report should:
- Identify the independent laboratory or qualified testing professional
- Include the specific lot number tested
- Report core freshness markers (peroxide value, K232, K270, Delta K)
- Clearly state total polyphenols in mg/kg
- Show the date of analysis
These measurements document the tested sample at the time of analysis. They should be read together with harvest information, origin, storage and handling — not as a medical promise.
How to read an olive oil lab report (in 60 seconds)
Start with total polyphenols, free acidity, peroxide value and the three UV indices. Always compare results from the same harvest and a comparable testing method.
Total Polyphenols (mg/kg)
The measured concentration of phenolic compounds in the tested sample. Results vary by cultivar,
harvest, processing, storage and testing method.
Free Acidity (%)
A classification parameter associated with the condition of the fruit and handling before extraction.
Peroxide Value
A primary oxidation marker that should be interpreted together with UV indices and sample age.
K232 / K270 / ΔK
UV absorbance indices used in extra virgin olive oil classification and oxidation assessment.

Frequently Asked Questions About Olive Oil Lab Reports
What is a good peroxide value for olive oil?
For extra virgin olive oil, peroxide value must be below 20. High-quality fresh oils are often significantly lower. Always read peroxide value together with K232, K270, Delta K, and the harvest date.
What does K270 indicate in olive oil?
K270 is a UV absorbance value associated with secondary oxidation compounds. Elevated values can indicate aging, poor storage, or quality issues.
Do high polyphenols guarantee better olive oil?
Not alone. True quality is a combination of strong polyphenols, low oxidation markers, a verified harvest date, and transparent origin and handling.
Where can I download Deliba’s current olive oil lab reports?
The original PDF reports are linked in the Ottobratico and Sinopolese result cards above. Report 37823 covers Ottobratico lot 1 25 O 2, and report 37839 covers Sinopolese lot 1 25 S 1. No registration is required.
What does the lot number mean?
A lot number identifies the production batch connected to a specific report. Match the lot on the bottle with the lot shown in the result table and PDF before treating a laboratory value as applicable to that bottle.
