Table sugar (sucrose) comes from plant sources. Two important sugar crops predominate: sugarcane (Saccharum spp.) and sugar beets (Beta vulgaris), in which sugar can account for 12% to 20% of the plant's dry weight. Some minor commercial sugar crops include the date palm (Phoenix dactylifera), sorghum (Sorghum vulgare), and the sugar maple (Acer saccharum). In the financial year 2001/2002, worldwide production of sugar amounted to 134.1 million tonnes.
The first production of sugar from sugar-cane took place in India. Alexander the Great's companions reported seeing "honey produced without the intervention of bees" and it remained exotic in Europe until the Arabs started cultivating it in Sicily and Spain. Only after the Crusades did it begin to rival honey as a sweetener in Europe. The Spanish began cultivating sugar-cane in the West Indies in 1506 (and in Cuba in 1523). The Portuguese first cultivated sugar-cane in Brazil in 1532.
Most cane-sugar comes from countries with warm climates, such as Brazil, Pakistan, India, China and Australia. In 2001/2002 developing countries produced over twice as much sugar as developed countries. The greatest quantity of sugar comes from Latin America, the United States, the Caribbean nations, and the Far East.
Beet-sugar comes from regions with cooler climates: northwest and eastern Europe, northern Japan, plus some areas in the United States (including California). In the northern hemisphere, the beet-growing season ends with the start of harvesting around September. Harvesting and processing continues until March in some cases. The availability of processing-plant capacity, and the weather both influence the duration of harvesting and processing - the industry can lay up harvested beet until processed, but frost-damaged beet becomes effectively unprocessable.
The European Union (EU) has become the world's second-largest sugar exporter. The Common Agricultural Policy of the EU sets maximum quotas for members' production to match supply and demand, and a price. Europe exports excess production quota (approximately 5 million tonnes in 2003). Part of this, "quota" sugar, gets subsidised from industry levies, the remainder (approximately half) sells as "C quota" sugar at market prices without subsidy. These subsidies and a high import tariff make it difficult for other countries to export to the EU states, or to compete with the Europeans on world markets.
The U.S. sets high sugar prices to support its producers, with the effect that many former consumers of sugar have switched to corn syrup (beverage-manufacturers) or moved out of the country (candy-makers).
The cheap prices of glucose syrups produced from wheat and corn (maize) threaten the traditional sugar market. In combination with artificial sweeteners, drink manufacturers can produce very low-cost products.
[edit] Cane
Cane-sugar producers crush the harvested vegetable material, then collect and filter the juice. They then treat the liquid (often with lime (calcium oxide)) to remove impurities and then neutralize it with sulfur dioxide. Boiling the juice then allows the sediment to settle to the bottom for dredging out, while the scum rises to the surface for skimming off. In cooling the liquid crystallises, usually in the process of stirring, to produce sugar crystals. Centrifuges usually remove the uncrystallised syrup. The producers can then either sell the resultant sugar, as is, for use; or process it further to produce lighter grades. This processing may take place in another factory in another country.
[edit] Beet
Sugar beets

Main article: Sugar beet
Beet-sugar producers slice the washed beets, then extract the sugar with hot water in a "diffuser". An alkaline solution ("milk of lime" and carbon dioxide from the lime kiln) then serves to precipitate impurities (see carbonatation). After filtration, evaporation concentrates the juice to a content of about 70% solids, and controlled crystallisation extracts the sugar. A centrifuge removes the sugar crystals from the liquid, which gets recycled in the crystalliser stages. When economic constraints prevent the removal of more sugar, the manufacturer discards the remaining liquid, now known as molasses.
Sieving the resultant white sugar produces different grades for selling.
[edit] Cane versus beet
Little perceptible difference exists between sugar produced from beet and that from cane. Tests can distinguish the two, and some tests aim to detect fraudulent abuse of EU subsidies or to aid in the detection of adulterated fruit-juice.
The production of sugar results in residues which differ substantially depending on the raw materials used and on the place of production. While cooks often use cane molasses in food, humans find molasses from sugar beet unpalatable, and it therefore ends up mostly as industrial fermentation feedstock, or as animal-feed. Once dried, either type of molasses can serve as fuel for burning.
[edit] Culinary sugars
So-called Raw sugars comprise yellow to brown sugars made from clarified cane-juice boiled down to a crystalline solid with minimal chemical processing. Raw sugars result from the processing of sugar-beet juice, but only as intermediates en route to white sugar. Types of raw sugar available as a specialty item outside the tropics include demerara, muscovado, and turbinado. Mauritius and Malawi export significant quantities of such specialty sugars. Manufacturers sometimes prepare raw sugar as loaves rather than as a crystalline powder, by pouring sugar and molasses together into molds and allowing the mixture to dry. This results in sugar-cakes or loaves, called jaggery or gur in India, pingbian tang in China, and panela, panocha, pile, piloncillo and "pão-de-açúcar" in various parts of Latin America. Truly raw sugar (unheated and made from sugar-cane grown on farms in South America) does not have a large market-share.
Mill white sugar, also called plantation white, crystal sugar, or superior sugar, consists of raw sugar where the production process does not remove colored impurities, but rather bleaches them white by exposure to sulfur dioxide. This is the most common form of sugar in sugarcane growing areas, but does not store or ship well; after a few weeks, its impurities tend to promote discoloration and clumping.
Blanco directo, a white sugar common in India and other south Asian countries, comes from precipitating many impurities out of the cane juice by using phosphatation — a treatment with phosphoric acid and calcium hydroxide similar to the carbonatation technique used in beet-sugar refining. In terms of sucrose purity, blanco directo is more pure than mill white, but less pure than white refined sugar.
White refined sugar has become the most common form of sugar in North America as well as in Europe. Refined sugar can be made by dissolving raw sugar and purifying it with a phosphoric acid method similar to that used for blanco directo, a carbonatation process involving calcium hydroxide and carbon dioxide, or by various filtration strategies. It is then further decolorized by filtration through a bed of activated carbon or bone char depending on where the processing takes place. Beet sugar refineries produce refined white sugar directly without an intermediate raw stage. White refined sugar is typically sold as granulated sugar, which has been dried to prevent clumping.

A Brief History of Sugar
Sugar as a commodity in its own right can be traced back several thousand years in China and India. A definite reference dates to 510 B.C. when soldiers of the Persian Emperor Darius saw sugar cane growing on the banks of the River Indus. They called it the reeds which produce honey without bees.
Much later it was grown in Persia and the Arabs took it to Egypt. The word sugar is itself derived from an Arabic word.
Sugar cane, to which all the earliest references refer, is a member of the grass family. It can grow up to 15 feet tall, with leaves at the top and a hollow stalk filled with a sweet juice or sap from which sugar can be extracted. A perennial tropical plant, it grows best in very warm climates. It is ready for harvesting after 10 to 20 months.

The Canary Islands are identified to be the sunshine hub of Europe! See that sunlight with hotelbye . Canary Islands give you a moderate temperatures and a selection of exceptional organic attractions. Five of its eight islands have already been reported a Biosphere Reserve, and the archipelago has four national parks. The most remarkable attractions in Canary Islands will be the beaches because they are just great for enjoyable in sunlight or experiencing water activities such as for example windsurfing and scuba diving. In Canary Islands you is likewise impressing by the interior interest like: walking, cycle touring, climbing and actually caving. Some of the very most spectacular attractions of Canary Islands are: the volcanic landscape of Lanzarote, the beaches of Fuerteventura and Gran Canaria using their mud dunes, or the green forests of La Palma and La Gomera.

In the event that it's a fruit they have seeds, otherwise it's a vegetable. And vegetables are usually grown in the ground while fruits are grown in trees.

The process of making sugar by evaporating juice from sugarcane developed in India around 500 BC. Sugarcane, a tropical grass, probably originated in New Guinea. During prehistoric times its culture spread throughout the Pacific Islands and into India. By 200 BC producers in China had begun to grow it too. Westerners learned of sugarcane in the course of military expeditions into India. Nearchos, one of Alexander the Great's commanders, described it as "a reed that gives honey without bees".
Originally, people chewed the cane raw to extract its sweetness. Sugar refining developed in South Asia, the Middle East and China, where sugar became a staple of cooking and desserts. Early refining methods involved grinding or pounding the cane in order to extract the juice, and then boiling down the juice or drying it in the sun to yield sugary solids that resembled gravel. The Sanskrit word for "sugar" (sharkara), also means "gravel". Similarly, the Chinese use the term "gravel sugar" (Traditional Chinese: 砂糖) for table sugar.
Sugar later spread to other areas of the world through trade.

The Arabs and Berbers introduced sugar to Western Europe when they conquered the Iberian peninsula in the 8th century AD. Crusaders also brought sugar home with them after their campaigns in the Holy Land, where they encountered caravans carrying "sweet salt".
The 1390s saw the development of a better press, which doubled the juice obtained from the cane. This permitted economic expansion of sugar plantations to Andalucia and to the Algarve. The 1420s saw sugar-production extended to the Canary Islands, Madeira and the Azores.
In August 1492 Christopher Columbus stopped at Gomera in the Canary Islands, for wine and water, intending to stay only four days. He became romantically involved with the Governor of the island, Beatrice de Bobadilla, and stayed a month. When he finally sailed she gave him cuttings of sugarcane, which became the first to reach the New World.
The Portuguese took sugar to Brazil. Hans Staden, published in 1555, writes that by 1540 Santa Catalina Island had 800 sugar-mills and that the north coast of Brazil, Demarara and Surinam had another 2000. Approximately 3000 small mills built before 1550 in the New World created an unprecedented demand for cast iron gears, levers, axles and other implements. Specialist trades in mold making and iron casting were inevitably created in Europe by the expansion of sugar. Sugar mill construction is the missing link of the technological skills needed for the Industrial Revolution that is recognized as beginning in the first part of the 1600s.
After 1625 the Dutch carried sugarcane from South America to the Caribbean islands — from Barbados to the Virgin Islands. The years 1625 to 1750 saw sugar become worth its weight in gold. Prices declined slowly as production became multi-sourced, especially through British colonial policy. Sugar-production increased in mainland North American colonies, in Cuba, and in Brazil. African slaves became the dominant plantation-workers as they proved resistant to the diseases of malaria and yellow fever. European indentured servants remained in shorter supply, susceptible to disease and overall forming a less economic investment. (European diseases such as smallpox had reduced the numbers of local Native Americans.)
With the European colonization of the Americas, the Caribbean became the world's largest source of sugar. These islands could supply sugar-cane using slave-labor and produce sugar at prices vastly lower than those of cane sugar imported from the East. Thus the economies of entire islands such as Guadaloupe and Barbados became based on sugar production. By 1750 the French colony known as Saint-Domingue (subsequently the independent country of Haiti) became the largest sugar-producer in the world. Jamaica too became a major producer in the 18th century. Sugar-plantations fueled a demand for manpower; between 1701 and 1810 ships brought nearly one million slaves to work in Jamaica and in Barbados.
During the eighteenth century, sugar became enormously popular and the sugar-market went through a series of booms. The heightened demand and production of sugar came about to a large extent due to a great change in the eating habits of many
Europeans. For example, they began consuming jams, candy, tea, coffee, cocoa, processed foods, and other sweet victuals in much greater numbers. Reacting to this increasing craze, the islands took advantage of the situation and began harvesting sugar in extreme amounts. In fact, they produced up to ninety percent of the sugar that the western Europeans consumed. Of course some islands were more successful than others when it came to producing the product. For instance, Barbados and the British Leewards can be said to have been the most successful in the production of sugar because it counted for 93% and 97% respectively of each island’s exports.
Planters later began developing ways to boost production even more. For example, they began using more animal manure when growing their crops. They also developed more advanced mills and began using better types of sugar-cane. Despite these and other improvements, the price of sugar reached soaring heights, especially during events such as the revolt against the Dutch[citation needed] and the Napoleonic Wars. Sugar remained in high demand, and the islands' planters knew exactly how to take advantage of the situation.
As Europeans established sugar-plantations on the larger Caribbean islands, prices fell, especially in Britain. By the eighteenth century all levels of society had become common consumers of the former luxury product. At first most sugar in Britain went into tea, but later confectionery and chocolates became extremely popular. Suppliers commonly sold sugar in solid cones and consumers required a sugar nip, a pliers-like tool, to break off pieces.
Sugar-cane quickly exhausts the soil in which it grows, and planters pressed larger islands with fresher soil into production in the nineteenth century. In this century, for example, Cuba rose to become the richest land in the Caribbean (with sugar as its dominant crop) because it had the only major island land-mass free of mountainous terrain. Instead, nearly three-quarters of its land formed a rolling plain — ideal for planting crops. Cuba also prospered above other islands because Cubans used better methods when harvesting the sugar crops: they adopted modern milling-methods such as water-mills, enclosed furnaces, steam-engines, and vacuum-pans. All these technologies increased productivity.
After the Haïtian Revolution established the independent state of Haiti, sugar production in that country declined and Cuba replaced Saint-Domingue as the world's largest producer.
Long established in Brazil, sugar-production spread to other parts of South America, as well as to newer European colonies in Africa and in the Pacific, where it became especially important in Fiji.
