Brown Sugar: Why It Is Brown
Before the birth of Jesus of Nazareth, sugarcane from which sugar is made was harvested on the shores of the Bay of Bengal; it spread to the surrounding territories of Malaysia, Indonesia, Indochina, and southern China. The Arabic people introduced "sugar" at that point a sticky paste, semi-crystallized and believed to have medicinal value to the Western world by bringing both the reed and knowledge for its cultivation to Sicily and then Spain in the eighth and ninth centuries.
Later, Venice—importing finished sugar from Alexandria—succeeded in establishing a monopoly over this new spice by the fifteenth century; at that point, it started buying raw sugar, and even sugarcane, and treating it in its own refineries.
Venice's monopoly, however, was short-lived. In , Portuguese navigator Vasco da Gama returned from India bringing the sweet flavoring to Portugal. Lisbon started to import and refine raw sugar, and, in the sixteenth century, it became the European sugar capital. It was not long before the sweetener was available in France, where its primary function continued to be medicinal, and during the reign of Louis XIV, sugar could be bought by the ounce at the apothecary.
By the s, sugar though still expensive was widely available to both upper and middle classes. Sugar is a broad term applied to a large number of carbohydrates present in many plants and characterized by a more or less sweet taste.
The primary sugar, glucose, is a product of photosynthesis and occurs in all green plants. In most plants, the sugars occur as a mixture that cannot readily be separated into the components. In the sap of some plants, the sugar mixtures are condensed into syrup. Juices of sugarcane Saccharum officinarum and sugar beet Beta vulgaris are rich in pure sucrose, although beet sugar is generally much less sweet than cane sugar. These two sugar crops are the main sources of commercial sucrose.
The sugarcane is a thick, tall, perennial grass that flourishes in tropical or subtropical regions. Sugar synthesized in the leaves is used as a source of energy for growth or is sent to the stalks for storage.
It is the sweet sap in the stalks that is the source of sugar as we know it. The reed accumulates sugar to about 15 percent of its weight. Sugarcane yields about 2,, tons of sugar per year. The sugar beet is a beetroot variety with the highest sugar content, for which it is specifically cultivated.
While typically white both inside and out, some beet varieties have black or yellow skins. About 3,, tons of sugar are manufactured from sugar beet. Other sugar crops include sweet sorghum, sugar maple, honey, and corn sugar. The types of sugar used today are white sugar fully refined sugar , composed of clear, colorless or crystal fragments; or brown sugar, which is less fully refined and contains a greater amount of treacle residue, from which it obtains its color.
Sugarcane takes about seven months to mature in a tropical area and about months in a subtropical area. At this time, fields of sugarcane are tested for sucrose, and the most mature fields are harvested first. In Florida, Hawaii, and Texas, standing cane is fired to burn off the dry leaves. In Louisiana, the six- to ten-feet 1. When the beets are delivered at the refinery, they are first washed and then cut into strips.
Next, they are put into diffusion cells with After being purifed, the clear juice undergoes vacuum evaporation to remove most of the water. In this process, four vacuum-boiling cells are arranged in series so that each succeeding cell has a higher vacuum. The vapors from one body can thus boil the juice in the next one, a method called multiple-effect evaporation. Next, the syrupy solution is vacuum-crystallized to form sugar crystals.
The remaining liquid is removed using centrifugaling and drying, and the sugar is packaged. The sugar beet solution, on the other hand, is purified by precipitating calcium carbonate, calcium sulfite, or both in it repeatedly.
Impurities become entangled in the growing crystals of precipitate and are removed by continuous filtration. The sugar beet sucrose solution, at this point, is also nearly colorless, and it likewise undergoes multiple-effect vacuum evaporation. The syrup is seeded, cooled, and put in a centrifuge machine. The finished beet crystals are washed with water and dried. The growth of the crystals continues until the pan is full.
When sucrose concentration reaches the desired level, the dense mixture of syrup and sugar crystals, called massecuite, is discharged into large containers known as crystallizers. Crystallization continues in the crystallizers as the massecuite is slowly stirred and cooled.
Once the sugar is centrifuged, it is "cut down" and sent to a granulator for drying. In some countries, sugarcane is processed in small factories without the use of centrifuges, and a dark-brown product noncentrifugal sugar is produced.
Centrifugal sugar is produced in more than 60 countries while noncentrifugal sugar in about twenty countries. The bagasse produced after extracting the juice from sugar cane is used as fuel to generate steam in factories. Increasingly large amounts of bagasse are being made into paper, insulating board, and hardboard, as well as furfural, a chemical intermediate for the synthesis of furan and tetrahydrofuran.
The beet tops and extracted slices as well the molasses are used as feed for cattle. It has been shown that more feed for cattle and other such animals can be produced per acre-year from beets than from any other crop widely grown in the United States. The beet strips are also treated chemically to facilitate the extraction of commercial pectin. The end product derived from sugar refining is blackstrap molasses. It is used in cattle feed as well as in the production of industrial alcohol, yeast, organic chemicals, and rum.
Mill sanitation is an important factor in quality control measures. Bacteriologists have shown that a small amount of sour bagasse can infect the whole stream of warm juice flowing over it. Modern mills have self-cleaning troughs with a slope designed in such a way that bagasse does not hold up but flows out with the juice stream.
Strict measures are taken for insect and pest controls. Because cane spoils relatively quickly, great steps have been taken to automate the methods of transportation and get the cane to the mills as quickly as possible. Maintaining the high quality of the end-product means storing brown and yellow refined sugars which contain two percent to five percent moisture in a cool and relatively moist atmosphere, so that they continue to retain their moisture and do not become hard.

In the United States, harvesting of both cane and sugar beet is done primarily by machine, although in some states it is also done by hand. The harvested cane stalks and beets are loaded mechanically into trucks or railroad cars and taken to mills for processing into raw sugar.
Once there, they are cleaned, washed, milled to extract juice, filtered, and purified. The result is a clear, sugar-filled juice. After being purifed, the clear juice undergoes vacuum evaporation to remove most of the water. Other articles you might like:. Also read article about Sugar from Wikipedia. User Contributions: 1.

Sugar is considered safe food ingredient, however, it can present inorganic elements as impurities uptake during cultivation and production process. Therefore, this study aimed at identifies the presence of these elements in granulated and brown sugar samples available for consumption in public places in several countries. Several essential and non-essential elements were determined in a large range of concentrations. The results are discussed comparing to maximum values foreseen in the international and Brazilian legislations. This is a preview of subscription content, access via your institution.

Глава Отделения криптографии АНБ была не просто женщиной, а очень привлекательной женщиной.
