Orange (fruit) facts for kids
|Orange blossoms and oranges|
An orange is a type of citrus fruit which people often eat. Oranges are a very good source of vitamins, especially vitamin C. Orange juice is an important part of many people's breakfast. The "sweet orange", which is the kind that are most often eaten today, grew first in Asia but now grows in many parts of the world.
Oranges are round orange-coloured fruit that grow on a tree which can reach 10 metres (33 ft) high. Orange trees have dark green shiny leaves and small white flowers with five petals. The flowers smell very sweet which attracts many bees.
An orange has a tough shiny orange skin. Inside, the fruit is divided into "segments", which have thin tough skins that hold together many little sections with juice inside. There are usually ten segments in an orange, but sometimes there are more. Inside each segment of most types of orange there are seeds called "pips". Orange trees can be grown from pips, but some types of orange trees can only be grown from "cuttings" (a piece cut off a tree and made to grow roots). The segments and the skin are separated by white stringy fibrous material called "pith". In most types of oranges, the skin can be peeled off the pith, and the segments can be pulled apart with the fingers to be eaten. In some oranges it is hard to take the skin off. With mandarin oranges, the skin, pith and segments can all be pulled apart very easily. Orange skin is often called "orange peel".
Oranges are an important food source in many parts of the world for several reasons. They are a commonly available source of vitamin C. They last longer than many other fruits when they are stored. They are easy to transport because each orange comes in its own tough skin which acts as a container. They can be piled into heaps or carried in bags, lunchboxes and shipping containers without being easily damaged.
Sweet orange trees were brought to Italy, Spain and Portugal from India in the fifteenth century (1400s). Before that time only sour oranges were grown in Italy. From Europe, orange trees were taken to the United States, South America, Africa and Australia, which all grow oranges for sale.
There are several different types of sweet orange. One of the most common types is called the "Valencia" orange, which comes from Spain and is also grown in Africa and Australia. It is one of the most important "commercial" oranges. (This means that it is grown for sale in shops.)
One type of sweet orange is called the "blood orange" or "sanguine orange" (sanguine means blood red). These oranges often have red marks on the skin, and some parts of the inside look as if they have blood in them. Some blood oranges make juice that is ruby red.
In the 1850s, in Brazil, there was a tree growing in a monastery garden that made very strange fruit. Inside each orange skin there was a large orange with no seeds. At the bottom of the orange was a baby orange, which was really the bigger orange's twin. The little orange made a strange bump at the bottom of the orange skin, that looked just like a human "belly-button". These oranges were named "Navel Oranges". They tasted very sweet, they had no seeds and they peeled quite easily. This made them a very good orange to grow "commercially". But they could not grow from seed. They could only grow from cuttings. Nowadays, thousands of these orange trees have been planted from cuttings. "Navel Oranges" are grown in California and exported to many countries of the world. Every navel orange in the world has the same genetic make up as the oranges on that tree in the monastery in Brazil.
Mandarins, small flattened oranges with skins that come off easily, are believed to have come from China. Now there are several varieties. These include "tangerines" which are redder than most mandarins, and "clementines" which are large, smooth and plump. Mandarins of all sorts are very useful lunchbox fruit, because they are easy to peel and eat, but do not get squashed easily.
Nowadays, many people of the world eat an orange or drink orange juice every day, because oranges are one of the best and cheapest sources of Vitamin C. Human bodies, unlike many other animals, do not manufacture Vitamin C, so a human needs vitamin C in their diet regularly. (Vitamin C helps the body to grow, to heal wounds and fight infection.) Oranges are also a very good source of dietary fibre. But they do not contain high amounts of minerals. If a person eats an orange and a banana together, then they have had a very nourishing snack that supplies both vitamins and minerals. oranges are sweet and juicy
Juice and other products
Oranges, whose flavor may vary from sweet to sour, are commonly peeled and eaten fresh or squeezed for juice. The thick bitter rind is usually discarded, but can be processed into animal feed by desiccation, using pressure and heat. It also is used in certain recipes as a food flavoring or garnish. The outermost layer of the rind can be thinly grated with a zester to produce orange zest. Zest is popular in cooking because it contains oils and has a strong flavor similar to that of the orange pulp. The white part of the rind, including the pith, is a source of pectin and has nearly the same amount of vitamin C as the flesh and other nutrients.
Although not as juicy or tasty as the flesh, orange peel is edible and has significant contents of vitamin C, dietary fiber, total polyphenols, carotenoids, limonene and dietary minerals, such as potassium and magnesium.
Products made from oranges
- Orange juice is obtained by squeezing the fruit on a special tool (a juicer or squeezer) and collecting the juice in a tray underneath. This can be made at home or, on a much larger scale, industrially. Brazil is the largest producer of orange juice in the world, followed by the United States, where it is one of the commodities traded on the New York Board of Trade.
- Frozen orange juice concentrate is made from freshly squeezed and filtered orange juice.
- Sweet orange oil is a by-product of the juice industry produced by pressing the peel. It is used for flavoring food and drinks and also in the perfume industry and aromatherapy for its fragrance. Sweet orange oil consists of approximately 90% D-limonene, a solvent used in various household chemicals, such as wood conditioners for furniture and—along with other citrus oils—detergents and hand cleansers. It is an efficient cleaning agent with a pleasant smell, promoted for being environmentally friendly and therefore, preferable to petrochemicals. D-limonene is, however, classified as irritating to the skin and as very toxic to aquatic life in different countries.
- Marmalade preserves are traditionally made with Seville oranges, which are less sweet. All parts of the fruit are used: the pith and pips (separated and placed in a muslin bag) are boiled in a mixture of juice, slivered peel, sliced-up flesh, sugar, and water to extract their pectin, which helps the conserve to set.
- Orange peel is used by gardeners as a slug repellent.
- Orange trees are a symbol of love and marriage in many cultures. Oranges are sometimes found in Renaissance paintings of married couples. One of the most famous is Jan van Eyck's "Wedding Portrait of the Arnolfini".
- Brides traditionally wear orange blossoms in their hair or carry them in their bouquet at their wedding. Orange blossoms are often part of the decoration on a wedding cake.
- Queen Victoria was given a coronet of gold and enamel orange blossoms by her husband Albert. When their children were born, he had a jeweller add tiny green oranges to the coronet.
- If an orange is peeled with a knife, it is possible to cut the peel off in one long unbroken piece. Schoolgirls in some countries chant a rhyme, and throw the long orange peel over their shoulder, then look at how it falls to find the initial letter of the name of the boy that loves them.
- In some countries, "blood oranges" are seen as a symbol of the death of Jesus.
- In some European countries, a "Christingle" is a Christmas decoration using an orange and a candle to symbolise Jesus' love for the world.
- In cold countries, when fruit was scarce, an orange was often given at Christmas. In England, it was traditional to stuff the toe of a child's Christmas stocking with raisins, almonds and oranges.
- Orange peel can be dried and treated with sugar. It is an ingredient in Christmas cakes.
- Oranges are sometimes used to make a sweet-smelling "pomander" to perfume a room. This is done by sticking the stalks of cloves into an orange, and allowing the orange to dry out.
- Orange jam is called "Marmalade". Traditionally, it is said to have been first made for Mary Queen of Scots or Marie Antoinette when they were sick. Neither of these stories is true, as marmalade was made in Portugal for many years before either of them was born. The term "marmalade", originally meaning a quince jam ("marmelada" in Portuguese), derives from the Portuguese word for this fruit marmelo.
- An English children's song about the church bells of London begins with the line "'Oranges and Lemons' say the Bells of St. Clements..."
