Oranges

I have retrieved this excellent ariticle from Wikipedia. It contains very relevant and useful information that I can take with me in my everyday life.

Orange—specifically, sweet orange—refers to the citrus tree Citrus sinensis (syn. Citrus aurantium L. var. dulcis L., or Citrus aurantium Risso) and its fruit. The orange is a hybrid of ancient cultivated origin, possibly between pomelo (Citrus maxima) and tangerine (Citrus reticulata). It is a small angiosperm tree growing to about 10 m tall with evergreen leaves, which are arranged alternately, of ovate shape with crenulate margins and 4-10 cm long. The orange fruit is a hesperidium.

The word "orange" ultimately comes from Sanskrit narang or Tamil "naraththai". Oranges originated in southeast Asia, in either India, Vietnam or southern China. The fruit of Citrus sinensis is called sweet orange to distinguish it from Citrus aurantium, the bitter orange. In a number of languages, it is known as a "Chinese apple" (e.g. Dutch Sinaasappel (China's apple)).

[edit] Fruit
All citrus trees are of the single genus Citrus, and remain largely interbreedable; that is, there is only one "superspecies" which includes lemons, limes and oranges. Nevertheless, names have been given to the various members of the citrus family, oranges often being referred to as Citrus sinensis and Citrus aurantium. Fruits of all members of the genus Citrus are considered berries because they have many seeds, are fleshy, soft and derive from a single ovary. An orange seed is sometimes referred to as a pip.

The Persian orange, grown widely in southern Europe after its introduction to Italy in the 11th century, was bitter. Sweet oranges were brought to Europe in the 15th century from India by Portuguese traders, quickly displaced the bitter, and are now the most common variety of orange cultivated. The sweet orange will grow to different sizes and colours according to local conditions, most commonly with ten carpels, or segments, inside.

Portuguese, Spanish, Arab, and Dutch sailors planted citrus trees along trade routes to prevent scurvy. On his second voyage in 1493, Christopher Columbus brought the seeds of oranges, lemons and citrons to Haiti and the Caribbean. They were introduced in Florida (along with lemons) in 1513 by Spanish explorer Juan Ponce de Leon, and were introduced to Hawaii in 1792.


A peeled sectioned navel orange. The underdeveloped twin is located on the bottom right.A single mutation in 1820 in an orchard of sweet oranges planted at a monastery in Brazil led to the navel orange, also known as the Washington, Riverside or Bahia navel. A single cutting of the original was then transplanted to Riverside, California in 1870, creating a new market worldwide. The mutation causes a 'twin' fruit, with a smaller orange embedded in the outer fruit opposite the stem. From the outside, the smaller, undeveloped twin leaves a formation at the bottom of the fruit, looking similar to the human navel. Navel oranges are almost always seedless, and tend to be larger than other sweet oranges. They are produced without pollination, through parthenocarpy. A newer variety of the navel orange, with pink flesh, is the Cara Cara navel.

The Valencia or Murcia orange is one of the sweet oranges used for juice extraction. It is a late-season fruit, and therefore a popular variety when the navel oranges are out of season. For this reason, the orange was chosen to be the official mascot of the 1982 FIFA World Cup, which was held in Spain. The mascot was called "Naranjito" ("little orange"), and wore the colours of the Spanish soccer team uniform.

The blood orange has streaks of red in the fruit, and the juice is often a dark burgundy colour. The fruit has found a niche as an interesting ingredient variation on traditional Seville marmalade, with its striking red streaks and distinct flavour. The mandarin orange is similar, but smaller and sweeter, and the scarlet navel is a variety with the same diploid mutation as the navel orange.

[edit] Juice and other products

Oranges and orange juice.Oranges are widely grown in warm climates worldwide, and the flavours of orange vary from sweet to sour. The fruit is commonly peeled and eaten fresh, or squeezed for its juice. It has a thick bitter rind that is usually discarded, but can be processed into animal feed by removing water using pressure and heat. It is also used in certain recipes as flavouring or a garnish. The outer-most layer of the rind is grated or thinly veneered with a tool called a zester, to produce orange zest, popular in cooking because it has a flavour similar to the fleshy inner part of the orange. The white part of the rind, called the pericarp or albedo and includes the pith, is a source of pectin and has nearly the same amount of vitamin C as the flesh.

Products made from oranges include:

Orange juice, one of the commodities traded on the New York Board of Trade. Brazil is the largest producer of orange juice in the world, followed by the USA.
Sweet orange oil, a by-product of the juice industry produced by pressing the peel. It is used as a flavouring of food and drink and for its fragrance in perfume and aromatherapy. Sweet orange oil consists of about 90% d-Limonene, a solvent used in various household chemicals, such as to condition wooden furniture, and along with other citrus oils in grease removal and as a hand-cleansing agent. It is an efficient cleaning agent which is environmentally friendly, and much less toxic than petroleum distillates. It also smells more pleasant than other cleaning agents.
The orange blossom, which is the state flower of Florida, is traditionally associated with good fortune, and was popular in bridal bouquets and head wreaths for weddings for some time. The petals of orange blossom can also be made into a delicately citrus-scented version of rosewater. Orange blossom water is a common part of Middle Eastern cuisine. The orange blossom gives its touristic nickname to the Costa del Azahar ("Orange-blossom coast"), the Valencia seaboard.
In Spain, fallen blossoms are dried and then used to make tea.
Orange blossom honey, or actually citrus honey, is produced by putting beehives in the citrus groves during bloom, which also pollinates seeded citrus varieties. Orange blossom honey is highly prized, and tastes much like orange.
Marmalade, a conserve made usually with Seville oranges. All parts of the orange are used to make marmalade: The pith and pips are separated, and typically placed in a muslin bag where they are boiled in the juice (and sliced peel) to extract their pectin, aiding the setting process.
Orange peel is used by gardeners as a Slug repellent.
Since oranges are susceptible to frost damage, growers commonly use sprinklers to coat them with ice when temperatures go below freezing. This practice protects the crops by regulating temperature.


[edit] Etymology
Main article: Orange (word)

Orange derives from Sanskrit nāraṅgaḥ "orange tree", but another explanation tries to establish a link to a Dravidian root meaning “fragrant”. Compare Tamil narandam [நரந்தம்] “bitter orange”, nagarukam [நாகருகம்] “sweet orange” and nari [நாரி] "fragrance". The Sanskrit or Dravidian word was borrowed into European languages through Persian nārang, Armenian nārinj, Arabic nāranj, (Spanish naranja and Portuguese laranja), Late Latin arangia, Italian arancia or arancio, and Old French orenge, in chronological order. The first appearance in English dates from the 14th century. The forms starting with n- are older; this initial n- may have been mistaken as part of the indefinite article, in languages with articles ending with an -n sound (eg. in French une norenge may have been taken as une orenge). The name of the colour is derived from the fruit, first appearing in this sense in 1542.

Some languages have different words for the bitter and the sweet orange, such as Modern Greek nerantzi and portokali ("Portuguese"), respectively. The reason for these is that the sweet orange was brought from China to Europe during the XVI century by the Portuguese. For the same reason, some languages refer to it by "Applesin" which means "Apple from China".
