Comparison of ohmic heating- and microwave-assisted extraction techniques for avocado leaves valorization: Optimization and impact on the phenolic compounds and bioactivities.

Avocado tree pruning activities generate a substantial amount of residual biomass, which includes different parts of the plant, such as leaves, twigs, branches, and small fruits. This study aimed to investigate the impact of different green extraction methods of microwave-assisted extraction (MAE) and ohmic heating-assisted extraction (OHAE) for the phenolic extraction of avocado leaves based on a statistical approach, central composite design (CCD), and response surface methodology (RSM). Water was preferred using as an environmentally and health-friendly solvent for both methods.
