From Waste to Resource: Extraction and Characterization of Polyphenols from Dalmatian Olive Mill Wastewater.

ABSTRACT:

Background

Olive cultivation and olive oil production are key agricultural sectors in the Dalmatia region, where numerous oil mills operate. Analyses have shown that extra virgin olive oils (EVOO) produced in this area contain respectable amounts of polyphenols, which contribute to superior oil quality due to their antioxidant properties. During processing, hydrophilic phenolic compounds predominantly transfer into olive mill wastewater (OMW), making it a concentrated source of valuable bioactive molecules. The antioxidant, anti-inflammatory, and photoprotective effects of these polyphenols are highly relevant for cosmetic and pharmaceutical use.

Methods

A total of 186 OMW samples were collected from oil mills in the Split-Dalmatia County across three production seasons (202
