Resumen:
This study evaluated the use of autohydrolysis as a green method to extract biophenols with antioxidant and antibiofilm
activities from Uruguayan olive pomace (OP), considering the formation of degradation compounds such as 5-hydroxymethylfurfural
(HMF). Response surface methodology was used to evaluate the effect of temperature, extraction time and liquid-solid ratio on extraction
yield (EY), total phenolic content (TPC), antioxidant activity (FRAP and DPPH assays), hydroxytyrosol (HTY) content and HMF
content. The optimal extraction conditions (168 °C, 24 min, and liquid-solid ratio of 20 mL/g) were determined to maximize EY (25.65
g/100 g), TPC (28.60 mgGAE/g), antioxidant activity (FRAP: 328.50 μmolFSE/g; DPPH: 122.33 μmolTRE/g) and HTY content (2.79
mg/g) while minimizing HMF content (0.92 mg/g). Under these conditions, the obtained extract showed greater protection for sunflower
oil than the synthetic antioxidants tested (BHA and BHT) and demonstrated the ability to inhibit the biofilm formation of Candida
albicans and Staphylococcus aureus.
