Subclass: Rosidae

Family: Rutaceae
Genus: Citrus
Species: C. sinensis

The blood orange is a variety of orange (Citrus sinensis) with crimson, blood-colored flesh. The fruit is smaller than an average orange; its skin is usually pitted, but can be smooth. The distinctive dark flesh color is due to the presence of anthocyanin, a pigment common to many flowers and fruit, but uncommon in citrus fruits. Sometimes there is dark coloring on the exterior of the rind as well, depending on the variety of blood orange. The reason for the unusual internal color is related to light, temperature and variety.[1] Download high resolution version (723x692, 83 KB)A plate filled with blood oranges; taken February 5, 2005, by Allen Timothy Chang. ...

The Moro, a recent addition to the blood orange family, is the most colorful of the three types, with a deep purple flesh and reddish orange rind. This fruit has a distinct, sweet flavor with a hint of raspberry particular to blood oranges. The Moro variety is believed to have originated at the beginning of the 19th century in the citrus-growing area around Lentini (in the Province of Siracusa in Sicily) as a bud mutation of the "Sanguigno". Moro are "full-blood" oranges, meaning that the flesh ranges from orange-veined with ruby coloration, to vermilion, to vivid crimson, and nearly to black. The thick orange-colored peel has a medium fine grain with spots or red wine veins. In botany, a rind is the thick outer skin of various structures such as fruit. ...

The Tarocco is a medium-sized fruit and is perhaps the sweetest and most flavorful of the three types. The most popular table orange in Italy, the Tarocco is thought to have derived from a mutation of the "Sanguinello". It is referred to as "half-blood", because the flesh is not accentuated in red pigmentation as much as with the Moro and Sanguinello varieties. It has thin orange skin, slightly blushed in red tones. The Tarocco is one of the world's most popular oranges because of its sweetness (Brix to acid ratio is generally above 12.0) and juiciness. It has the highest Vitamin C content of any orange variety grown in the world, mainly on account of the fertile soil surrounding Mount Etna, and it is easy to peel. The Tarocco orange is seedless, and it contains anthocyanins, as do other blood oranges. The name Tarocco is thought to be derived from an exclamation of wonder expressed by the farmer who was shown this fruit by its discoverer. It has been suggested that Öchsle scale and Baumé scale be merged into this article or section. ... For other uses, see Vitamin C (disambiguation). ...

The Sanguinello (Sahn-gwee-NAY-o), discovered in Spain in 1929, has a reddish skin, few seeds, and a sweet and tender flesh. Sanguinello, the Sicilian late "full-blood" orange, is close in characteristics to the Moro. It matures in February, but can remain on trees unharvested until April. Fruit can last until the end of May. The peel is compact, and clear yellow with a red tinge. The flesh is orange with multiple blood-colored streaks. Year 1929 (MCMXXIX) was a common year starting on Tuesday (link will display the full calendar) of the Gregorian calendar. ...
