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. It is nearly pure sucrose.
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. It is nearly pure sucrose.
The refining process completely removes the molasses from cane juice or beet juice to give the disaccharide 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 that 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 but classified as var. saccharifera . 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 byproduct, 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 age of the plant. Sugarcane molasses is usually used to sweeten and flavour foods. Molasses is a major constituent of fine commercial brown sugar.
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.
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.
Sucanat is a brand name for a variety of whole cane sugar that was introduced by Pronatec in 1978. Like panela and muscovado, Sucanat retains its molasses content. It is essentially pure dried sugar cane juice. The juice is extracted by mechanical processes, heated, and cooled, forming small brown grainy crystals.
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.
The history of sugar has five main phases:
The International Commission for Uniform Methods of Sugar Analysis (ICUMSA) is an international standards body, founded in 1897, that publishes detailed laboratory procedures for the analysis of sugar.
Rhum agricole is the French term for sugarcane juice rum, a style of rum originally distilled in the French Caribbean islands from freshly squeezed sugarcane juice rather than molasses. Rhum is the term that typically distinguishes it in French-speaking locales from the rum made with molasses in other parts of the West Indies.
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.
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.
A beet sugar factory, or sugar factory, is a type of production facility that produces sugar from sugar beets. Nowadays, most sugar factories also act as a sugar refinery. The first beet sugar factory was built in 1802.
