Characteristics of Sour Orange
The sour orange fruit is small to medium in size, with a thick, rough skin that is often green when unripe and turns to yellow or orange as it matures. The flesh is divided into segments and is extremely sour and bitter, making it inedible in its raw form for most people. The tree itself is evergreen, with dark green, elliptical leaves that have wings on the petioles, a characteristic feature of many citrus species.
Uses of Sour Orange
Despite its bitter taste, sour orange has several uses. The fruit is used in marmalades and as a zest in culinary preparations due to its intense citrus flavor. The flowers are a source of neroli oil, which is highly valued in perfumery for its fragrance. Moreover, sour orange is used in traditional medicine for its various health benefits, including its antioxidant, anti-inflammatory, and antimicrobial properties.

The primary use of bitter orange is in the production of marmalade, where its bitter flavor and high pectin content make it an ideal ingredient. The peel of bitter oranges is also used in culinary preparations for its flavor, and the essential oil extracted from the peel, known as bergamot oil, has applications in aromatherapy and cosmetics.

While sour orange and bitter orange share a common lineage and some similarities, they are distinct in several aspects.
