Multifunctional Potential, Bioactivity, and Food Applications of Citrus limon and Punica granatum Peels

Résumé

This book explores the multifunctional potential of lemon (Citrus limon) and pomegranate (Punica granatum) peels as valuable sources of bioactive compounds for food, pharmaceutical, and nutraceutical applications. It highlights the rich composition of phenolics, flavonoids, tannins, alkaloids, and essential oils present in these agro-industrial by-products and examines their antioxidant, antimicrobial, anti-inflammatory, antidiabetic, hepatoprotective, and cardioprotective activities. The work also discusses advanced extraction technologies, mechanisms of biological action, and the incorporation of peel-derived compounds into functional foods, edible coatings, packaging materials, and dietary supplements. In addition, it addresses safety considerations, quality control, regulatory frameworks, and sustainability aspects related to peel valorization. By integrating scientific evidence with industrial perspectives, the book demonstrates how lemon and pomegranate peels can be transformed from agricultural waste into high-value functional ingredients supporting circular bioeconomy strategies.
