Advanced extraction techniques for sustainable recovery of health-promoting compounds from carob leaves

Year: 2025

Type: article

Abstract: , 20 min) conditions ensured exhaustive recovery of target compounds with negligible formation of extraction artefacts (gallic acid and digalloylglucoses), preserving antioxidant and α-glucosidase inhibitory activities. Compared with conventional techniques, PHWE and probe-UAE demonstrated a low environmental footprint, reducing extraction time, solvent use and environmental impact, while improving extraction yield and extract quality. PHWE generated fully aqueous extracts suitable for direct application, whereas probe-UAE offered high energy efficiency and operational simplicity. These findings demonstrate the potential of green extraction techniques for the sustainable valorization of carob leaves, providing high-value bioactive extracts and supporting the development of healthy food products. This study offers novel insights into the exploitation of untapped plant biomasses and provides a practical approach for integrating green innovations into the food and nutraceutical sectors.
