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.

Description

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
12
H

O

. [2] White sugars produced from sugar cane and sugar beet are chemically indistinguishable: it is possible, however, to identify its origin through a carbon-13 analysis. [1]

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 but classified as var. saccharifera . Its closest wild relative is the sea beet.

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.

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.

<span class="mw-page-title-main">History of sugar</span>

The history of sugar has five main phases:

  1. The extraction of sugar cane juice from the sugarcane plant, and the subsequent domestication of the plant in tropical India and Southeast Asia sometime around 4,000 BC.
  2. The invention of manufacture of cane sugar granules from sugarcane juice in India a little over two thousand years ago, followed by improvements in refining the crystal granules in India in the early centuries AD.
  3. The spread of cultivation and manufacture of cane sugar to the medieval Islamic world together with some improvements in production methods.
  4. The spread of cultivation and manufacture of cane sugar to the West Indies and tropical parts of the Americas beginning in the 16th century, followed by more intensive improvements in production in the 17th through 19th centuries in that part of the world.
  5. The development of beet sugar, high-fructose corn syrup and other sweeteners in the 19th and 20th centuries.

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.

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.
