It is a hybrid fruit that belongs to the Rutaceae family. People value oranges for their sweet flavor and nutritional benefits. They can be eaten fresh or processed into juice and fragrant peels. The orange is a hesperidium, which is a specialized type of modified berry. This fruit is non-climacteric, meaning it does not continue to ripen after being picked from the tree.

An orange tree is an evergreen flowering tree with an average height of several meters. The leaves are oval with crenulate margins, which means they have small, rounded teeth along the edges. Inside the fruit, there is a thick, grainy rind. Attached to this rind is a white, bitter tissue called the albedo, or pith. The interior contains about ten distinct carpels, which are segments delimited by a membrane. Each segment contains many juice-filled vesicles and usually a few pips, or seeds.

Scientists classify the Citrus sinensis group into four distinct classes. These include common oranges, blood oranges, which have pigmented flesh, navel oranges, and acidless oranges. The sweet orange is not a wild species but a product of domestication in East Asia. It originated in a region covering Southern China, Northeast India, and Myanmar. Genomic analysis shows the sweet orange is a hybrid of the mandarin orange and the pomelo. Specifically, it is approximately 58% mandarin and 42% pomelo.

The history of the orange involves many different cultures and migrations. The earliest written mention of the sweet orange appears in Chinese literature from 314 BC. During the Arab Agricultural Revolution, the Moors introduced citrus fruits to the Iberian Peninsula. Large-scale cultivation began in the 10th century using complex irrigation techniques. In the late 15th century, Italian and Portuguese merchants brought the sweet orange to the Mediterranean. By the 17th century, oranges were a luxury in Europe, often grown in private conservatories called orangeries.

Oranges played a major role in the development of the Americas. Spanish travelers introduced the fruit to the American continent, possibly as early as 1493. By the mid-1500s, sweet oranges reached Mexico and South America. In California, the gold rush of 1849 increased the demand for oranges. Miners needed the vitamin C in the fruit to prevent scurvy. This demand helped the citrus industry grow rapidly. By 1885, the completion of railroads and ventilated boxcars allowed for national distribution.

Global production of oranges is massive and highly concentrated in certain regions. In 2022, approximately 76 million tonnes of oranges were grown worldwide. Brazil is the leading producer, accounting for 22% of the total global output. India and China are also major contributors to this total. In California, the industry saw a huge expansion between 1875 and 1901. During this time, the number of citrus trees grew from 90,000 to 4.5 million.

The orange has also left a lasting mark on human culture and language. Artists have depicted the fruit for centuries, from Zhao Lingrang in the Song dynasty to Vincent van Gogh. Even the word "orange" has a long journey through different languages. It began with the Dravidian languages of South India and passed through Sanskrit, Persian, and Arabic. The color itself was named after the fruit, with the first English use of "orange" as a color recorded in 1512.

Beyond taste, the chemical composition of the orange is quite complex. The flesh is 87% water and 12% carbohydrates. It is a rich source of vitamin C, providing 59% of the Daily Value in a standard serving. Oranges also contain various phytochemicals like carotenoids and flavonoids. These include substances such as beta-carotene and naringenin. Volatile organic compounds, such as esters and terpenes, provide the characteristic orange aroma.
