Truffles are edible symbiotic hypogeal fungi and highly prized worldwide for their unique aroma and rich nutritional profile. Belonging to the order Pezizales and family Tuberaceae, with the genus Tuber being the most notable, truffles contain a diverse array of bioactive compounds including phenols, terpenoids, polysaccharides, anandamide, fatty acids, and ergosterols. These compounds contribute to a wide range of biological activities such as antioxidant, antibacterial, anti-inflammatory, hepatoprotective, and anticancer effects. This review comprehensively summarizes current scientific evidence on the biochemical composition, nutritional and aromatic properties, and biological activities of truffles, with special emphasis on their antioxidant and anti-tumor potential. Additionally, factors influencing truffle productivity and quality as well as advanced extraction and storage techniques to preserve bioactivity are discussed, highlighting their potential as valuable functional foods and sources of natural antioxidants.
