Green recovery of the lipid fraction from olive stones by supercritical CO₂ extraction: Process optimization and characterization for food applications

Federico Basso, Erica Moret, Luisa Barba, Hazem Jabeur, Ilem Hassairi, Hana Maalej, Sonia Calligaris.

This study explores the sustainable recovery of the residual lipid fraction contained in olive stones using supercritical CO₂ extraction, a green and solvent-free technology. The recovered lipid fraction was comprehensively characterized to assess its potential for food and bio-based applications, further demonstrating the value of olive stones within the circular bioeconomy and supporting innovative, sustainable value chains from olive oil by-products.
