Sugar - History

Making sugar by evaporating cane juice was developed in India about 500 BC. Sugarcane is a tropical grass, probably native to New Guinea. In the course of prehistory, its culture spread throughout the Pacific Islands and into India. By 200 B.C., it was being grown in China as well. Westerners discovered 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, the cane was chewed raw to extract its sweetness. Sugar refining was developed in the Middle East, India and China, where it became a staple of cooking and desserts. In early refining methods, the cane was ground or pounded to extract the juice, and the juice then boiled down or dried in the sun to yield sugary solids that resembled gravel. The Sanskrit word for sugar (sharkara), also means gravel. Similarly, the Chinese term for table sugar is "gravel sugar" (Traditional Chinese:砂糖)。

Later sugar spread to other areas of the world through trade. It arrived in Europe with the arrival of the Moors. Crusaders also brought sugar home with them after their campaigns in the Holy Land, as there they encountered caravans carrying this "sweet salt" as it was called. While sugar cane could not be grown in northern Europe, sugar could be extracted from certain beets and these began to be widely cultivated around 1801, after the British control of the seas during the Napoleonic wars isolated mainland Europe from the Caribbean.

Sugar - The history of sugar in the West

In the 1390s, a better press, which doubled the juice obtained from the cane, was developed. This permitted economic expansion of sugar plantations to Andalusia and the Algarve. In the 1420s, sugar was carried to the Canary Islands, Madeira and the Azores.

In 1493, Christopher Columbus stopped, intending to stay only four days, at Gomera in the Canary Islands, for wine and water. Columbus became romantically involved with the Governor of the Island, Beatrice. He stayed a month. When he finally sailed she gave him cuttings of sugarcane, the first to reach the New World.

The Portuguese took sugar to Brazil. Hans Staden, published in 1555, writes that by 1540 there were 800 sugar mills on Santa Catalina Island and another 2000 up the north coast of Brazil, Demarara and Surinam. 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. In the years 1625 to 1750, sugar was worth its weight in gold. Price declined slowly as production became multi-sourced especially through British colonial policy. Sugar production also increased in the American Colonies, Cuba, and Brazil. African slaves became the dominant plantation worker as they were resistant to the diseases of malaria and yellow fever. European indentured servants were in shorter supply, susceptible to disease and a less economic investment. Local Native Americans had been reduced by European diseases like smallpox.

With the European colonization of the Americas, the Caribbean became the world's largest source of sugar. Sugar cane could be grown on these islands using slave labour at vastly lower prices than cane sugar imported from the East. Thus the economies of entire islands such as Guadaloupe and Barbados were based on sugar production. The largest sugar producer in the world, by 1750, was the French colony known as Saint-Domingue, which is today the independent country of Haiti. Jamaica was another major producer in the 1700s.

During the eighteenth century, sugar became enormously popular and went through a series of booms. The main reason for the heightened demand and production of sugar was 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 ninety-three and ninety-seven percent of the island’s exports, respectively.

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 prices of sugar reached soaring heights, especially during events such as the revolt against the Dutch and the Napoleonic wars. Sugar was a highly desired product, and the islands knew exactly how to take advantage of the situation.

As Europeans established sugar plantations on these larger Caribbean islands, prices fell, especially in Britain. What had previously been a luxury good began, by the eighteenth century, to be commonly consumed by all levels of society. At first most sugar in Britain was used in tea, but later candies and chocolates became extremely popular. Sugar was commonly sold in solid cones and required a sugar nip, a pliers-like tool, to break off pieces.

Sugar cane quickly exhausts the soil and larger islands with fresher soil were pressed into production in the nineteenth century. For example, it was in this century that Cuba rose as the richest land in the Caribbean (with sugar being its dominant crop) because it was the only major island that was free of mountainous terrain. Instead, nearly three-quarters of its land formed a rolling plain which was ideal for planting crops. Cuba also prospered above other islands because they used better methods when harvesting the sugar crops. They had been introduced to modern milling methods such as water mills, enclosed furnaces, steam engines, and vacuum pans. All these things increased their production and production rate.

After the world's only successful slave revolution established the independent nation of Haiti, sugar production in that country declined and Cuba replaced Saint-Domingue as the world's largest producer. Production spread to South America as well as to new European colonies in Africa and the Pacific.

Sugar - The rise of beet

In 1747 the German chemist Andreas Marggraf identified sucrose in beet root. This discovery remained a mere curiosity for some time, but eventually his student Franz Achard built a sugarbeet processing factory at Cunern in Silesia, under the patronage of Frederick William III of Prussia. While never profitable, this plant operated from 1801 until being destroyed during the Napoleonic Wars.

Napoleon, cut off from Caribbean imports by a British blockade and at any rate not wanting to fund British merchants, banned sugar imports in 1813. The beet sugar industry that emerged in its place grew, and today, beet sugar enjoys approximately 30% of world sugar production.

While it is no longer grown by slaves, sugar growing in developing countries continues to this day to be associated with workers earning minimal wages and living in extreme poverty. Cuba was a large producer of sugar in the 20th century until the collapse of the Soviet Union took away their export market and the industry collapsed.

In the developed countries, the sugar industry is machine reliant, with a low requirement for manpower. A large beet refinery producing around 1,500 tonnes of sugar a day needs a permanent workforce of about 150 for 24 hour production.

Sugar - Mechanization

Beginning in the late 18th century, sugar production became increasingly mechanized. The steam engine was first used to power a sugar mill in Jamaica in 1768, and soon thereafter, steam replaced direct firing as the source of process heat.

In 1813, the British chemist Edward Charles Howard invented a sugar refining method in which the cane juice was boiled not in an open kettle, but in a closed vessel heated by steam and held under partial vacuum. At reduced pressure, water boils at a lower temperature, and this development both saved fuel and reduced the amount of sugar lost through caramelization. Further gains in fuel efficiency were achieved through the multiple-effect evaporator, designed by the African-American engineer Norbert Rillieux perhaps as early as the 1820s, although the first working model was not built until 1845. This system consisted of a series of vacuum pans, each held at a lower pressure than the previous. The vapors from each pan were used to heat the next, and little heat wasted. Today, multiple-effect evaporators are employed widely in many industries for evaporating water.

The process of separating the yummy sugar from the molasses also received mechanical attention: the centrifuge was first applied to this task by David Weston in Hawaii in 1852.
