Tangerines

Tangerines are related varieties of oranges. They generally distinguished from oranges by their smaller size, loose, easily peelable skin (pericarp) and sweet juicy flesh (arils). They are also known as mandarin oranges in europe and satsumas in japan. Just as in oranges, they too belong within the rutaceae (citrus family) and known scientifically as citrus reticulata. Mandarin orange thought to have originated in south-eastern tropical forest of china. Today, it is widely grown in many parts of the world, as far as california, as an important commercial crop.

The tangerine tree is smaller than oranges with slender branches, and 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 underside of skin and edible arils. An average-sized fruit has 8-10 juicy segments (arils). Several hybrid varieties of tangerines exist: tangelos, also known as honeybell,aare 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 cross between oranges (c. Sinensis) and tangerine (c. Reticulata). They feature large size, and sweet-tart flavor similar to oranges. Clementines, another member of citrus family, are cross between mandain and sweet oranges. They are smaller, have smooth glossy skin, and very sweet, juicy, almost seedless segments. Yuzu fruit or japanese citrus fruit is a hybrid between c. Ichngenesis and mandarin oranges (c. Reticulata). They are characterized by intense lime-like fragrance and tart flavor.

In addition, the citrus fruits are very rich sources of vitamin-c (ascorbic acid), a water-soluble vitamin. Vitamin-c is one of the powerful natural anti-oxidant, which has many essential roles like collagen synthesis, wound healing, anti-viral, anti-cancer activity, and help prevent from neuro-degenerative diseases, arthritis, and cold/fever..etc., by removing oxidant-free radicals from the body. Vitamin c helps absorb iron in the food by reducing ferrous form of the iron elements to ferric form in the gut.

Further, they contain natural soluble and insoluble fiber like hemi-cellulose, 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 scientifically established that citrus fruits, especially oranges, by virtue of their richness in vitamins and minerals, have many proven health benefits. Moreover, it is now beginning to be appreciated that the other biologically active, non-nutrient compounds found in citrus fruits such as phyto-chemical antioxidants; soluble and insoluble dietary fibers play a vital role in reduction in the risk for cancers, many chronic diseases like arthritis, and from obesity and coronary heart diseases.
