White sugar, also called table sugar, granulated sugar, or regular sugar, is a commonly used type of sugar, made either of beet sugar or cane sugar, which has undergone a refining process.
White sugar, also called table sugar, granulated sugar, or regular sugar, is a commonly used type of sugar, made either of beet sugar or cane sugar, which has undergone a refining process.
The refining process completely removes the molasses to give the white sugar, sucrose. It has a purity higher than 99.7%. [1] Its molecular formula is C

White sugar (and some brown sugar) produced from sugar cane may be refined using bone char by a few sugar cane refiners. [3] Beet sugar has never been processed with bone char and is vegan. [4]
From a chemical and nutritional point of view, white sugar does not contain—in comparison to brown sugar—some minerals (such as calcium, potassium, iron and magnesium) present in small quantities in molasses. [5] [6] [7] The only detectable differences are, therefore, the white color and the less intense flavor. [7]
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose, lactose, and maltose. White sugar is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars.
A sugar beet is a plant whose root contains a high concentration of sucrose and which is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet. Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies Beta vulgaris subsp. vulgaris. Its closest wild relative is the sea beet.
Sucrose, a disaccharide, is a sugar composed of glucose and fructose subunits. It is produced naturally in plants and is the main constituent of white sugar. It has the molecular formula C

Molasses is a viscous substance, principally obtained from the refining of sugarcane, or sugar beet juice into sugar. Molasses varies in the amount of sugar, the method of extraction and the age of the plant. Sugarcane molasses is usually used to sweeten and flavour foods. Molasses is a major constituent of fine commercial brown sugar. It is also one of the main ingredients used to distill rum.
In cooking, syrup is a condiment that is a thick, viscous liquid consisting primarily of a solution of sugar in water, containing a large amount of dissolved sugars but showing little tendency to deposit crystals. In its concentrated form, its consistency is similar to that of molasses. The viscosity arises from the multiple hydrogen bonds between the dissolved sugar, which has many hydroxyl (OH) groups.
A refinery is a production facility composed of a group of chemical engineering unit processes and unit operations refining certain materials or converting raw material into products of value.
A sugarloaf was the usual form in which refined sugar was produced and sold until the late 19th century, when granulated and cube sugars were introduced. A tall cone with a rounded top was the end product of a process in which dark molasses, a rich raw sugar that was imported from sugar-growing regions such as the Caribbean and Brazil, was refined into white sugar.
Brown sugar is a sucrose sugar product with a distinctive brown color due to the presence of molasses. It is by tradition an unrefined or partially refined soft sugar consisting of sugar crystals with some residual molasses content, but is now often produced by the addition of molasses to refined white sugar.
A sugar refinery is a refinery which processes raw sugar from cane or sugar extracted from beets into white refined sugar.
Golden syrup or light treacle is a thick, amber-coloured form of inverted sugar syrup made by the process of refining sugar cane or sugar beet juice into sugar. It is used in a variety of baking recipes and desserts. It has an appearance and consistency similar to honey, and is often used as a substitute where honey is unavailable.
Sugarcane or sugar cane is a species of tall, perennial grass that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. It is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea. Grown in tropical and subtropical regions, sugarcane is the world's largest crop by production quantity, totaling 1.9 billion tonnes in 2020, with Brazil accounting for 40% of the world total. Sugarcane accounts for 79% of sugar produced globally. About 70% of the sugar produced comes from Saccharum officinarum and its hybrids. All sugarcane species can interbreed, and the major commercial cultivars are complex hybrids.
The history of sugar has five main phases:
A sugar cane mill is a factory that processes sugar cane to produce raw sugar or plantation white sugar. Some sugar mills are situated next to a back-end refinery, that turns raw sugar into (refined) white sugar.
Sugar Cane Growers Cooperative of Florida is a vertically integrated agricultural enterprise that harvests, transports and processes sugarcane grown primarily in Palm Beach County, Florida and markets the raw sugar and blackstrap molasses through the Florida Sugar and Molasses Exchange. The Cooperative is made up of 45 grower-owners who produce sugarcane on approximately 70,000 acres of some of the most fertile farmland in America, located in the Everglades Agricultural Area (EAA). Sugarcane grown by Cooperative members is harvested, transported and processed. The raw sugar is then marketed to one of the ASR Group's sugar refineries. The Cooperative produces more than 350,000 tons of raw sugar annually.
Non-centrifugal cane sugar (NCS) is the technical name given to traditional raw sugar obtained by evaporating water from sugarcane juice. NCS is internationally recognized as a discrete and unique product by the FAO since 1964 and by the World Customs Organization (WCO) since 2007. WCO defines NCS as "cane sugar obtained without centrifugation". It also states that "the product contains only natural anhedral micro-crystals, of irregular shape, not visible to the naked eye, which are surrounded by molasses' residues and other constituents of sugar cane". NCS is produced in most sugarcane-growing regions of the world, being known by many different names such as panela, jaggery, or gur. Some varieties of muscovado are non-centrifugal.
The sugar industry of the United States produces sugarcane and sugar beets, operates sugar refineries, and produces and markets refined sugars, sugar-sweetened goods, and other products. The United States is among the world's largest sugar producers. Unlike most other sugar producing countries, the United States has both large and well-developed sugarcane and sugar beet industries. Refined sugarcane, processed sugar beet, and high-fructose corn syrup are all commonly used in the U.S. as added sugars to sweeten food and beverages.
A beet sugar factory or sugar factory, is a type of sugar production facility that produces sugar from sugar beet. Nowadays most sugar factories also act as a sugar refinery. The first beet sugar factory was founded in 1802.
The Waterloo sugar factory is a former sugar factory in Waterloo, in the south of the former Province of Brabant in Belgium. The building was a sugar factory from 1836 to 1871. Later it was used by a dairy company. The industrial area is now known as Waterloo Office Park.
