Sugar alcohols can be, and often are, produced from renewable resources.Particular feedstocks are starch, cellulose and hemicellulose; the main conversion technologies use H 2 as the reagent: hydrogenolysis, i.e. the cleavage of C−O single bonds, converting polymers to smaller molecules, and hydrogenation of C=O double bonds, converting sugars to sugar alcohols.
Xylitol occurs naturally in small amounts in plums, strawberries, cauliflower, and pumpkin; humans and many other animals make trace amounts during metabolism of carbohydrates. [10] Unlike most sugar alcohols, xylitol is achiral. [12] Most other isomers of pentane-1,2,3,4,5-pentol are chiral, but xylitol has a plane of symmetry.
Sucrose (table sugar) is the prototypical example of a sweet substance. Sucrose in solution has a sweetness perception rating of 1, and other substances are rated relative to this. [ 13 ] For example, another sugar, fructose , is somewhat sweeter, being rated at 1.7 times the sweetness of sucrose. [ 13 ]
Attar, or qatir (Arabic: قَطْر) is a type of sweet syrup used in the preparation of Middle Eastern desserts.It is made of primarily sugar and water, and is reduced slightly until somewhat golden and thicker.
Hydrogenated starch hydrolysates are used commercially in the same way as other common sugar alcohols. They are often used as both a sweetener and as a humectant (moisture-retaining ingredient). As a crystallization modifier, they can prevent syrups from forming crystals of sugar.
Simple syrup (also known as sugar syrup, or bar syrup) is a basic sugar-and-water syrup. It is used by bartenders as a sweetener to make cocktails, and as a yeast feeding agent in ethanol fermentation. The ratio of sugar to water is 1:1 by volume for normal simple syrup, but can get up to 2:1 for rich simple syrup. [6]
Xylitol pentacetate is an organic compound with the formula C 15 H 22 O 10. It is an acetylated sugar alcohol that is used as an intermediary in the production of xylitol pentanitrate . [ 2 ] It is also commonly made to isolate and identify xylitol from complex organic mixtures.
The word "alcohol" derives from the Arabic kohl (Arabic: الكحل, romanized: al-kuḥl), a powder used as an eyeliner. [12] The first part of the word ( al- ) is the Arabic definite article , equivalent to the in English.
