of orange peel
Orange peel is rich in vitamin C, dietary fiber, and flavonoid antioxidants, particularly hesperidin and naringin. It also contains essential oils with potential anti-inflammatory and antimicrobial properties.
About
Orange peel is the thick outer skin of the orange fruit (Citrus × sinensis), a hybrid citrus fruit believed to originate in Southeast Asia. The peel comprises two distinct layers: the thin, oil-rich colored outer layer called the zest (flavedo), and the white, porous inner layer called the pith (albedo). Fresh orange peel exhibits a dimpled, textured surface with a bright orange hue, while dried orange peel turns darker and becomes brittle. The flavor profile is intensely citrusy, bitter, and aromatic, with pronounced notes of limonene and other volatile oils that define its character.
Culinary Uses
Orange peel is used in both fresh and dried forms across numerous culinary traditions. The zest—thin strips or gratings of the outer colored layer—provides bright citrus flavor to desserts, beverages, marinades, and savory dishes without the bitterness of the pith. Dried orange peel is a staple in Chinese cuisine, particularly in Sichuan and Cantonese cooking, where it adds depth to braises, stir-fries, and rice dishes. It is also candied (confit) as a confectionery and used to infuse spirits, syrups, and teas. In Western baking, fresh zest brightens cakes, cookies, and custards, while dried peel appears in spice blends, broths, and medicinal infusions.
