Blood oranges are a sweet, juicy citrus fruit with deep red or crimson flesh. They are a natural mutation of typical oranges and are rich in potassium, vitamin C, and fiber. They are used in cooking, cocktails, and aromatherapy, and are grown in Sicily, California, and Florida.
The blood orange is a variety of the popular citrus fruit named for its deep red or crimson flesh. The red color is derived from anthocyanin, a pigment usually found in red fruits and flowers. Blood oranges are sweet, juicy, and less acidic than other orange varieties. They are also slightly smaller than the common orange table and have a pitted or smooth outer skin. Some types of blood oranges are dark red on the outside, and most are seedless.
Blood oranges are believed to be natural mutations of typical oranges that have spread continuously since their first appearance. The blood orange was first documented in Italy in the opera Hesperides in 1646, where it was called “red orange.” The fruit was not documented in Europe until around 1850, although it may have been cultivated here before this. Blood oranges were eventually exported to North America, where they are also known as pigmented and blood oranges.
Blood oranges were first cultivated in Sicily, where they are still grown today. As the demand for the sweet red oranges grew, the Sicilians began to export the fruit to other countries. Today, the blood orange is also grown in California and Florida in the United States, although the climate in Florida creates blood oranges that lack the characteristic red flesh.
There are three main cultivars of the blood orange: Sanguinello, Moro, and Tarocco. The Sanguinello cultivar has a red skin, red flesh, and few seeds. The Moro variety features deep crimson flesh, red-orange skin, and a stronger flavor and aroma than the other types. The Tarocco cultivar is the sweetest of the three, with orange skin and red-tinged flesh. The Tarocco blood orange is also known as a “crossbreed” because it is not as pigmented as the other cultivars.
All blood oranges are rich in potassium, vitamin C, and dietary fiber. One medium-sized blood orange can provide up to 30 percent of the recommended daily value for fiber and 130 percent of the recommended daily value for vitamin C. The fruit is also free of fat, saturated fat, cholesterol, and sodium.
In addition to being eaten raw, blood oranges have numerous culinary uses. They are generally used in exactly the same way as other types of oranges. The juice from blood oranges is used to make jam, jelly, sherbet, soft drinks, and even salad dressings. The juice is also a popular ingredient in cocktails, probably due to its red color, and the zest is often used in baking.
Blood orange essential oil has a distinctive aroma that is much stronger than other orange oils. It is used in aromatherapy as an antidepressant and is also valued for its energy-boosting properties. The oil is a common herbal remedy in some parts of Europe to treat digestive problems. Other essential oil uses include treating external pain, bruises and aches, and indigestion.
