Polyphenols are naturally occurring compounds found in olives and other plants. In olive oil, reported phenolic content is a chemistry measure that can be associated with bitterness, pungency and oxidative stability; total phenols are not interchangeable with hydroxytyrosol-plus-derivatives measurement used for the EU-authorised wording.
This reported total-phenol result is not the hydroxytyrosol-plus-derivatives measurement used to assess the EU-authorised olive-oil wording.
