Abstract: As a traditional Chinese medicinal and culinary ingredient, dried tangerine peel is known to be rich in various natural bioactive components, including volatile oils, flavonoids, phenolic acids, and alkaloids. These substances endow dried tangerine peel with excellent antioxidant, anti-inflammatory, anti-Alzheimer, and spleen-stomach regulating effects, so it has shown great application and development potential in functional foods, drugs, and other fields. This article summarizes recent research on the changes, transformation mechanisms and biological activities of active substances during the aging process of dried tangerine peel. It comprehensively reviews the current state of research on the aging mechanism and biological activity of dried tangerine peel, and proposes future research directions and application prospects, aiming to provide a theoretical basis for the development of dried tangerine peel and its related products.

Key words: dried tangerine peel; active components; microorganism; aging mechanism; biological activity
