Conference Abstract Book

Case Study: Deep Eutectic Solvents (DES) Life Cycle Assessment (LCA) comparison of different extraction methods for flavonoid extraction from Ginkgo biloba leaves: Flavonoid Extraction from Ginkgo biloba Methods Compared: • DES Extraction (DESE): Choline chloride/glycerine (ChCl/Gly) • Traditional HRE: Ethanol • UAE: Ethanol Key Findings: • DES extraction showed 28.0%-35.2% higher flavonoid content than aqueous ethanol • DES method demonstrated lower ecological toxicity Agricultural Waste Valorization Thinned Peach Fruit Application: • Significant source of polyphenols and other bioactive compounds • Transforms agricultural waste into valuable extracts • Contributes to circular economy principles Other Food Applications: • Pesticide determination and removal • Heavy metal removal from food products • Biodegradable packaging films preparation Future Potential: DESs show promise for broader food industry applications, including safety improvements and waste reduction. 13/17
