Overview

Randomized trial evaluates hydrothermal extraction efficiency in olive oil waste, suggesting a greener method for antioxidants.

Key Points

  • The research aims to optimize a green method for extracting phenolic compounds from olive oil industry waste.
  • Optimized hydrothermal extraction method using Box–Behnken design
  • Extraction conditions set at 0.54% acetic acid, 120°C, for 15 min
  • Validation experiments confirmed predictive capacity for phenolic compounds and antiradical activity.
  • Yielded 13.86 mg caffeic acid/g for o-diphenols and 22.45 mg caffeic acid/g for total phenolics
  • Achieved 81.47% DPPH inhibition for antiradical activity
  • Demonstrated 3.09 mmol trolox/g for reducing activity, showing superior efficiency over traditional ethanolic methods.
