Origin / Growing regions

Oranges originally came from China, where they were discovered some 3,000 years ago. Today they grow in the subtropical regions, in the Mediterranean countries, in South America (Brazil), in the U.S. (Florida and California) and in South Africa and southern China.

Description

Oranges, the most important type of citrus fruit, are a product of a natural cross between the grapefruit and the tangerine. Some 1,000 varieties have been identified. They grow on evergreen trees in a wide range of shapes which grow to heights of up to eight metres.

Fruit

Depending on the variety, the fruits vary considerably with respect to size, shape, colour and other characteristics. Clearly distinguishable from the widely known “blonde oranges” (which are used primarily in juice production) are blood oranges (red skin and pulp) and navel oranges (which have clearly recognizable blossom roots and secondary fruits). Beneath the dull yellow to reddish-orange skin lies white, furry layer which must be removed before the fruit is consumed.

Flavour

The sweet-sour taste of the orange comes from the varying distribution of sugars and acids and the numerous aromatic substances contained in the fruit. Careful selection of fruit makes it possible to produced especially mild, easily digestible varieties.

Distinctive characteristics

Oranges are important sources of vitamins and are among the richest fruits in vitamin C (40 – 80 mg per 100 g).
