The
blood orange (called "red" orange in Italy and Spain and orange "blood" in English) is a variety of orange common Mediterranean fruit of the orange ( Citrus sinensis ), the color of the pulp tends to blood red. The coloring is progressing with centripetal maturation.
There are "blood" forms of the most common oranges: Maltese blood, blood Vaniglia (without blood acidity rarely cultivated because it keeps evil), just as there are blood mandarin (Clementine "Rubino").
Blood is more or less colored outside and inside of varieties, the maturity, the amplitudes and thermal exposure of the fruit. We distinguish between "light blood" "clear blood" and "Deep bood" or "dark blood".
Blood color is due to the presence of anthocyanins (the pigment of blueberries), pigment rare in citrus whose color is usually due to another family of pigments: carotenoids (pigment tomato). These carotenoids can reach a high density of red and Cara cara navel orange to pink or red flesh, depending on climate, grapefruit ( Citrus × paradisi) pink or red pulp (Star Ruby, Rio Red) are indeed red without being called "blood." Anthocyanins are antioxidants whose virtues for our health are highlighted by current research, their presence in blood oranges stimulates the creation of new cultivars highly colored.
Use
Blood oranges are mainly used for juice because, as the most common orange, they will not peel.
This juice is more acidic than navel oranges, so it is used by the current leaders in cold preparations (Joel Robuchon: Emulsion blood orange jelly berries), or ice such as sorbet.
They accompany fish and shellfish in the current kitchen which enjoys its color.
Health Benefits of Blood orange
One of the benefits of blood oranges is they have higher antioxidant levels than other varieties of oranges. The coloring of the orange represents the presence of anthocyanins, which are available in other dark colored fruits like cranberries.
