What are olive oil polyphenols and why do they matter

The Component That Separates a Good EVOO From an Extraordinary One

When an expert tastes an extra virgin olive oil and detects that characteristic bitterness and the pungency felt in the throat, they are perceiving something very specific: polyphenols. These bioactive compounds are one of the great quality markers in a premium EVOO and the reason why early harvest is so important.

What exactly are polyphenols?

Polyphenols are organic compounds of plant origin with antioxidant properties. In extra virgin olive oil, the most relevant ones are:

• Hydroxytyrosol — one of the most potent natural antioxidants known
• Oleocanthal — responsible for the characteristic pungency, with a structure similar to ibuprofen
• Oleuropein — present in green olives, decreases with ripening
• Tyrosol — contributes to the oil's oxidative stability

The greener and earlier the harvest, the higher the concentration of these compounds in the resulting oil.

The European statement on polyphenols

The European Union officially recognizes the benefits of olive oil polyphenols. Regulation (EU) No. 432/2012 authorizes the following health claim:

"Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress."

To use this claim, the oil must contain at least 5 mg of hydroxytyrosol and its derivatives per 20 g of oil. Sangre de Olivo Elixir, thanks to its early harvest and Picual variety, achieves polyphenol levels far superior to the market average.

Why early harvest makes a difference

The concentration of polyphenols in the olive is highest when the fruit is green. As it ripens, these compounds naturally degrade. Therefore, harvesting earlier — even if less oil is obtained per kilo of olives — is the only way to preserve this natural richness at its peak.

At Sangre de Olivo Elixir, every production decision is aimed at maximizing quality: from the exact moment of harvest to packaging in premium cans that protect the oil from light and oxidation.

How to recognize an EVOO rich in polyphenols

You don't need a laboratory to detect them. An EVOO with a high polyphenol content tells you on the palate:

• Present but elegant bitterness
• Pungency that appears in the throat when swallowing
• Intense green color (especially in early harvest)
• Fresh aromas: grass, green tomato, almond, fig tree

If an oil is not pungent or bitter, its polyphenols have probably already degraded. Excellence has its own taste.
