Sunflower by-products valorization: Chemical characterization, modeling, and thermodynamic study. (PubMed, Bioresour Technol) - Oct 5, 2026 - "Extraction kinetics of chlorogenic acid (CGA) were investigated from sunflower meal (SM) and hulls (SH) using pressurized water extraction (PWE) at different temperatures (120-160 °C)...Thermodynamic and Damköhler analyses confirmed diffusion-controlled extraction and revealed distinct activation behaviors for SM and SH, reflecting the strong influence of matrix structure on CGA release and transformation. This work is the first to demonstrate that PWE not only enables the green extraction of CGA from sunflower by-products but also reveals its thermal transformation."
