A sweetener is a substance added to food or drink to impart the flavor of sweetness, either because it contains a type of sugar, or because it contains a sweet-tasting sugar substitute. Various natural non-sugar sweeteners and artificial sweeteners are used to produce food and drink.
Many artificial sweeteners have been invented and are now used in commercially produced food and drink. Natural non-sugar sweeteners also exist, [1] such as glycyrrhizin found in liquorice. [2]
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.
Sucralose is an artificial sweetener and sugar substitute. As the majority of ingested sucralose is not metabolized by the body, it adds no calories. In the European Union, it is also known under the E number E955. It is produced by chlorination of sucrose, selectively replacing three of the hydroxy groups—in the C1 and C6 positions of the fructose portion and the C4 position of the glucose portion—to give a 1,6-dichloro-1,6-dideoxyfructose–4-chloro-4-deoxygalactose disaccharide. Sucralose is about 600 times sweeter than sucrose, three times as sweet as both aspartame and acesulfame potassium, and twice as sweet as sodium saccharin.
Fructose, or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion. The liver then converts both fructose and galactose into glucose, so that dissolved glucose, known as blood sugar, is the only monosaccharide present in circulating blood.
A sugar substitute is a food additive that provides a sweetness like that of sugar while containing significantly less food energy than sugar-based sweeteners, making it a zero-calorie or low-calorie sweetener. Artificial sweeteners may be derived through manufacturing of plant extracts or processed by chemical synthesis. Sugar substitute products are commercially available in various forms, such as small pills, powders, and packets.
Corn syrup is a food syrup which is made from the starch of corn/maize and contains varying amounts of sugars: glucose, maltose and higher oligosaccharides, depending on the grade. Corn syrup is used in foods to soften texture, add volume, prevent crystallization of sugar, and enhance flavor. It can be processed into high-fructose corn syrup (HFCS) by using the enzyme D-xylose isomerase to convert a large proportion of its glucose into sweeter fructose.
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.
Shasta Beverages is an American soft drink manufacturer that markets a value-priced soft drink line with a wide variety of soda flavors, as well as a few drink mixers, under the brand name Shasta. The company name is derived from Mount Shasta in northern California and the associated Shasta Springs.
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.
Brown rice (malt) syrup, also known as rice syrup or rice malt, is a sweetener which is rich in compounds categorized as sugars and is derived by steeping cooked rice starch with saccharifying enzymes to break down the starches, followed by straining off the liquid and reducing it by evaporative heating until the desired consistency is reached. The enzymes used in the saccharification step are supplied by an addition of sprouted barley grains to the rice starch or by adding bacterial- or fungal-derived purified enzyme isolates.
High-fructose corn syrup (HFCS), also known as glucose–fructose, isoglucose and glucose–fructose syrup, is a sweetener made from corn starch. As in the production of conventional corn syrup, the starch is broken down into glucose by enzymes. To make HFCS, the corn syrup is further processed by D-xylose isomerase to convert some of its glucose into fructose. HFCS was first marketed in the early 1970s by the Clinton Corn Processing Company, together with the Japanese Agency of Industrial Science and Technology, where the enzyme was discovered in 1965.
Glucose syrup, also known as confectioner's glucose, is a syrup made from the hydrolysis of starch. Glucose is a sugar. Maize (corn) is commonly used as the source of the starch in the US, in which case the syrup is called "corn syrup", but glucose syrup is also made from potatoes and wheat, and less often from barley, rice and cassava.p. 21
Agave syrup, also known as maguey syrup or agave nectar, is a sweetener commercially produced from several species of agave, including Agave tequilana and Agave salmiana. Blue-agave syrup contains 56% fructose as a sugar providing sweetening properties.
Hydrogenated starch hydrolysates (HSHs), also known as polyglycitol syrup, are mixtures of several sugar alcohols. Hydrogenated starch hydrolysates were developed by the Swedish company Lyckeby Starch in the 1960s. The HSH family of polyols is an approved food ingredient in Canada, Japan, and Australia. HSH sweeteners provide 40 to 90% sweetness relative to table sugar.
In the United States, Mexican Coca-Cola, or Mexican Coke or, informally, "Mexicoke", refers to Coca-Cola produced in and imported from Mexico. The Mexican formula that is exported into the U.S. is sweetened with white sugar instead of the high-fructose corn syrup used in the American formula since the early 1980s. Some tasters have said that Mexican Coca-Cola tastes better, while other blind tasting tests reported no perceptible differences in flavor.
Critics and competitors of high-fructose corn syrup (HFCS), notably the sugar industry, have for many years used various public relations campaigns to claim the sweetener causes certain health conditions, despite the lack of scientific evidence that HFCS differs nutritionally from sugar. The HFCS industry has tried to respond to these campaigns with their own efforts.
High-maltose corn syrup (HMCS) is a food additive used as a sweetener and preservative. The majority sugar is maltose. It is less sweet than high-fructose corn syrup and contains little to no fructose. It is sweet enough to be useful as a sweetener in commercial food production, however. To be given the label "high", the syrup must contain at least 50% maltose. Typically, it contains 40–50% maltose, though some have as high as 70%.
Added sugars or free sugars are sugar carbohydrates added to food and beverages at some point before their consumption. These include added carbohydrates, and more broadly, sugars naturally present in honey, syrup, fruit juices and fruit juice concentrates. They can take multiple chemical forms, including sucrose, glucose (dextrose), and fructose.
