Tangerines are a variety of citrus fruits and closely related to Oranges. They distinguished from oranges by their smaller size, loose, easily peelable skin (pericarp) and more sweeter juicy flesh (arils).
They also known as mandarin oranges in Europe. In Japan, a closely related seedless variety of mandarins known as Unshu mikan or satsuma mandarin grown in abundance in Kagoshima prefecture. Just as in oranges, mandarins also belong to the Rutaceae (Citrus Family) and known scientifically as Citrus reticulata.

Mandarin oranges私人电影网 thought to have originated in South-Eastern tropical forests of China. Today, it is widely grown in many parts of the world, as far as California, Philippines (Dalanghita) and South Africa (naartjie in Afrikaans) as an important commercial crop.
私人电影网Tangerine tree is smaller than orange, with slender branching and foliage-deep-green leaves with pointed ends. The fruit is flat, small compared to "Navel" or "Valencia" oranges. Its loose, deep-orange color skin (pericarp) can be peeled rather easily. Inside, it features extensive fibrous pith, which is loosely attached to the inner skin and edible arils. An average-sized fruit has 8-10 juicy segments (arils).

私人电影网Several hybrid varieties of tangerines exist:
Tangelos, also known as honeybells, are a hybrid between tangerine and orange (Citrus sinensis) or grapefruit (Citrus paradisi). Tangelos, like tangerines, have loose skin and juicy sweet flavored segments. They are distinguished from oranges by a characteristic knob at the stem end of the fruit.
Tangors (Citrus nobilis) are a cross between oranges (C. sinensis) and tangerine (C. reticulata). They feature large size, and sweet-tart flavor similar to oranges.
Clementines私人电影网, another member of the citrus family, are hybrid between a mandarin and sweet oranges. They are smaller, have smooth, glossy skin, and very sweet, juicy, almost seedless segments.
Yuzu fruit or Japanese citrus fruit私人电影网 is a hybrid between C. ichngenesis and mandarin oranges (C. reticulata). They characteristically have intense lime-like fragrance and tart flavor.
As in oranges, Tangerines too are very low (53 calories/100 g) in calories. Nevertheless, they are valuable sources of flavonoid antioxidants like naringenin, naringin, hesperetin, vitamin-A, carotenes, xanthins, and lutein; in fact, many times higher than in the oranges.
Also, the citrus fruits are very rich sources of vitamin-C (ascorbic acid), a water-soluble vitamin. Vitamin-C is one of the powerful natural antioxidant, which play vital role in collagen synthesis, wound healing, antiviral, anti-cancer activity, and help prevent from neuro-degenerative diseases, arthritis, and cold/fever by removing oxidant-free radicals from the body. Vitamin-C helps in the absorption of iron in the food by reducing it from ferrous form to efficiently absorbing ferric form in the gut.
Further, they contain natural soluble and insoluble fiber like hemicellulose, pectin...etc., which prevents cholesterol absorption in the gut. Adequate fiber in the food aids in smooth bowel movements by acting as a laxative.
Citrus fruits, as such, have long been valued for their wholesome nutritious and antioxidant properties. It is a scientifically established fact that citrus fruits, especially oranges, by their richness in vitamins and minerals, have many proven health benefits. Moreover, nutritionists begin to appreciate the benefits of other biologically active, non-nutrient compounds in citrus fruits such as phytochemical antioxidants. Soluble and insoluble dietary fibers play a vital role in the reduction of risk factors for cancers, many chronic diseases like arthritis, and from obesity and coronary heart diseases.
