Blood orange
Introduction
The blood orange is a variety of orange (Citrus sinensis) that is characterized by its deep red to reddish-purple flesh and juice. This distinctive feature is due to the presence of anthocyanins, a type of pigment that is more commonly found in flowers and grapes. The blood orange is a popular fruit among citrus enthusiasts and chefs, who prize it for its unique flavor and color.
