Mannitol Sorbitol Galactitol Iditol. As a group, sugar alcohols are not as sweet as sucroseand they have slightly less food energy than sucrose. Uses authors parameter CS1 maint: In addition to their sweetness, some sugar alcohols can produce a noticeable cooling sensation in the mouth when highly concentrated, for instance in sugar-free hard candy or chewing gum.

Sugar alcohols are usually incompletely absorbed into the blood stream from the small intestine which generally results in a smaller change in blood glucose than “regular” sugar sucrose. The table above presents the relative sweetness and food energy of the most widely used sugar alcohols.

Journal of thermal analysis. This page was last edited on 30 Decemberat The cooling sensation is due to the dissolution of the sugar alcohol being an endothermic heat-absorbing reaction [1]one with a strong heat of solution. Xylitol and lactitol are obtained similarly.

Most have five- or six-carbon chains, because they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively.

Sugar alcohols also called polyhydric alcoholspolyalcoholsalditols or glycitols are organic compoundstypically derived from sugarsthat comprise a class of polyols. In commercial foodstuffs, sugar alcohols are commonly used in place of table sugar sucroseoften in combination with high intensity artificial sweeteners to counter the low sweetness.

More than a million tons of sorbitol are produced in this way every year. Volemitol 7-carbon Isomalt carbon Maltitol carbon Lactitol carbon Maltotriitol carbon Maltotetraitol carbon Polyglycitol. Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources.

Despite the variance in food energy content of sugar alcohols, EU labeling requirements assign a blanket value of 2. A Practical Handbookp. They are white, water-soluble solids that can occur naturally or be produced industrially from sugars.

Their flavor is like sucrose, and they can be used to mask the unpleasant aftertastes of some high intensity sweeteners. Xylitol and sorbitol are popular sugar alcohols in commercial foods. Arabitol 5-carbon Xylitol 5-carbon Ribitol 5-carbon.

Both disaccharides and monosaccharides can form azudares alcohols; however, sugar alcohols derived from disaccharides e. Some individuals experience such symptoms even in a single-serving quantity. Studies have shown xylitol to be a deterrent to tooth decay. Unlike sugars, which tend to exist as rings, sugar alcohols do not.

Consumption of sugar alcohols affects blood sugar levels, although much less than does sucrose comparing by glycemic index. They are further differentiated by the relative orientation stereochemistry of these OH groups. In other projects Wikimedia Commons. Yale New Haven Health.

With continued use, most people develop a degree of tolerance to sugar alcohols and no longer experience these symptoms. They have one OH group attached to each carbon.

Today, they are often obtained by hydrogenation of sugars, using Raney nickel catalysts. From Wikipedia, the free encyclopedia.

Views Read Edit View history. Ethylene glycol [ citation needed ]. They are used widely in the food industry as thickeners and sweeteners.

This property makes them popular sweeteners among diabetics and people on low-carbohydrate diets. Sugar alcohols do not contribute to tooth decay. Retrieved January 6, Erythritol on the other hand is obtained by fermentation of glucose and sucrose. The sugar alcohols differ in chain length.

Sugar alcohols are not metabolized by oral bacteria, and so they do not contribute to tooth decay. Retrieved 6 January Ullmann’s Encyclopedia of Industrial Chemistry.
