HOW CANE SUGAR IS MADE – THE BASIC STORY 7
The English word „sugar“ may ultimately originate from the Sanskrit word sharkara or sarkara, which means „sugar“ or „pebble“. It probably came to English by way of the French, Spanish and/or Italians who derived their word for sugar from the Arabic al sukkar (whence the Portuguese word aзucar, the Spanish word azъcar, the Italian word zucchero, the Old French word zuchre and the ccontemporary French word sucre). The Arabs in turn presumably derived their word from the Persian shakar, derived from the original Sanskrit.
Note that the English word jaggery (coarse brown Indian sugar) has similar ultimate etymological origins. * 1PRODUCTION
The first production of sugar from sugar-cane took place in India.. Alexander the Great 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 CCrusades did it begin to rival honey as the 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.
Table sugar or sucrose ccomes from plant sources. Two important sugar crops predominate: sugarcane (Saccharin spp.) and sugar beets (Beta vulgarise), 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 vulgar), and the sugar maple (Acer saccharin). In the financial year 2001/2002 ,worldwide production of sugar amounted to 134.1 million tonnes .
Most cane sugar comes from countries with warm climates, such as Brazil India China and Australia (in descending order of production). 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 ssugar comes from regions with cooler climates: northwest and eastern Europe, northern Japan, plus some areas in the United States including California. 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 wworld’s second-largest sugar exporter. The Common Agricultural Policy 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. * 1CULINARY SUGARS
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 DDemerara, muscovite, and turbinate. 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 moulds and allowing the mixture to dry. This results in sugar-cakes or loaves, called jiggery or guar in India, penguin tong in China, and pineal, panache, pile, and piloncillo in various parts of Latin America.
Mill white sugar, also called plantation white, crystal sugar, or superior sugar, consists of raw sugar where the production process does not remove coloured impurities, but rather bleaches them white by exposure to sulphur 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 direct, 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 carbonization technique used in beet-sugar refining. In terms of sucrose purity, blanc direct is more pure than mill white, but less pure than white refined sugar.
White refined sugar has bbecome 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 direct, a carbonization 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.
Granulated sugar comes in various crystal sizes — for home and industrial use — depending on the application:
• Coarse-grained sugars, such as sanding sugar (nabbed sugar or sugar nibs) find favour for decorating cookies (biscuits) and other desserts.
• Normal granulated sugars for table use: typically they have a grain size about 0.5 mm across
• Finer grades result from selectively sieving the granulated sugar
• caster sugar (0.35 mm), commonly used in baking
• superfine sugar, also called baker’s sugar, berry sugar, or bar sugar — favoured for sweetening drinks or for preparing meringue
• Finest grades
• Powdered sugar, 10X sugar,
confectioner’s sugar (0.060 mm), or icing sugar (0.024 mm), produced by grinding sugar to a fine powder. The manufacturer may add a small amount of anti-caking agent to prevent clumping — either cornstarch (1% to 3%) or tri-calcium phosphate.
Retailers also sell sugar cubes or lumps for convenient consumption of a standardised amount.
Brown sugars derive from the late stages of sugar refining, when sugar forms fine crystals with significant molasses-content, or by coating white refined sugar with a cane molasses ssyrup .Their colour and taste become stronger with increasing molasses-content, as do their moisture-retaining properties. Brown sugars also tend to harden if exposed to the atmosphere, although proper handling can reverse this. * 1HISTORY
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 ggrow it too. Westerners learned of sugarcane in the course of military expeditions into India. Inarches, 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 ssweetness. Sugar refining developed in the Middle East India 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“ (shirkers), also means „gravel“. Similarly, the Chinese use the term „gravel sugar“ (Traditional Chinese) for table sugar. Sugar later spread to other areas of the world through trade. * 1SUGAR’S EFFECT ON YOUR HEALTH
The average American consumes an astounding 2-3 pounds of sugar each week, which is not surprising considering that highly refined sugars in the forms of sucrose (table sugar), ddextrose (corn sugar), and high-fructose corn syrup are being processed into so many foods such as bread, breakfast cereal, mayonnaise, peanut butter, ketchup, spaghetti sauce, and a plethora of microwave meals. In the last 20 years, we have increased sugar consumption in the U.S. 26 pounds to 135 lbs. of sugar per person per year! Prior to the turn of this century (1887-1890), the average consumption was only 5 lbs. per person per year! Cardiovascular disease and cancer was virtually uunknown in the early 1900’s.
The „glycolic index“ is a measure of how a given food affects blood-glucose levels, with each food being assigned a numbered rating. The lower the rating, the slower the absorption and digestion process, which provides a more gradual, healthier infusion of sugars into the bloodstream. On the other hand, a high rating means that blood-glucose levels are increased quickly, which stimulates the pancreas to secrete insulin to drop blood-sugar levels. These rapid fluctuations of blood-sugar levels are not healthy because of the stress they place on the body.
One of sugar’s major drawbacks is that it raises the insulin level, which inhibits the release of growth hormones, which in turn depresses the immune system. This ...
