Circular valorization of green leafy side streams via pressurized liquid extraction techniques for recovery of bioactive compounds.

ABSTRACT: Vegetable side streams are resulting non-edible by-products from vegetable processing. These side streams are a rich source of bioactive compounds and macromolecules. Despite their potential for high-value applications, these materials are frequently used in low-value applications or discarded, contributing to resource depletion and environmental concerns. This study investigates the valorization of vegetable side streams, specifically artichoke, broccoli, cauliflower, and spinach leaves, through pressurized liquid extraction (PLE) techniques aimed at recovering bioactive extracts. Two PLE methods were compared: low-pressure hot water extraction (LPHW) and sequential subcritical water extraction (s-SWE). The s-SWE method yielded higher cumulative extraction and demonstrated superior effici
