The convergence of botanical extraction technologies, functional food development, and circular economy principles represents a transformative pathway for sustainable agri-food systems. This research synthesizes interdisciplinary evidence from phytochemistry, food science, consumer behavior, and sustainability studies to critically examine how bioactive compounds derived from plant sources can be efficiently extracted, incorporated into food products, and aligned with circular consumption models. The study evaluates extraction techniques, including conventional and advanced methods, in terms of efficiency, scalability, and environmental impact, highlighting their role in preserving phenolic compounds and antioxidants essential for human health. Further, it explores the physiological benefits of plant-derived compounds such as flavonoids and phenolics, emphasizing their role in metabolic regulation, antimicrobial activity, hepatoprotection, and gastrointestinal health.
The research also integrates consumer-centric frameworks, examining how consumer perceptions of quality, safety, and sustainability influence the adoption of functional foods. Drawing from circular economy literature, the study investigates how food waste reduction, co-creation processes, and open innovation strategies can enhance the lifecycle value of botanical-based products. The findings reveal that integrating extraction optimization with circular design principles can significantly reduce environmental footprints while improving economic viability.
Moreover, the study identifies key challenges, including technological limitations, consumer skepticism, and policy gaps, that hinder widespread adoption. By bridging these domains, the research contributes a comprehensive theoretical framework that supports the development of sustainable, health-oriented, and economically viable agri-food innovations. The implications extend to industry stakeholders, policymakers, and researchers aiming to foster resilient food systems that prioritize both human health and environmental sustainability.
