Ethylene glycol 2-carbon Glycerol 3-carbon Erythritol 4-carbon Threitol 4-carbon. Food containing xylitol increased bone density in rat studies. However, like many other incompletely digestible substances, overconsumption of sugar alcohols can lead to bloatingdiarrhea and flatulence because they are not fully absorbed in the small intestine. Mannitol 6-carbon Sorbitol 6-carbon Galactitol 6-carbon Fucitol 6-carbon Iditol 6-carbon Inositol 6-carbon; a cyclic sugar alcohol.

This happens, for example, with the crystalline phase of sorbitolerythritolxylitolmannitollactitol and maltitol.

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. A Practical Handbookp. Most alcohholes five- or six-carbon chains, because they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively.

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 alcholes. This property makes them popular sweeteners among diabetics and people on low-carbohydrate diets. Despite the variance in food energy content of sugar alcohols, EU labeling requirements assign a blanket value of 2.

Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources. They can however be dehydrated to give cyclic ethers, e. As an exception, erythritol is actually absorbed in the small intestine and excreted unchanged through urine, so it contributes no calories even though it azucards rather sweet.

Unlike sugars, which tend to exist as rings, sugar alcohols do not. Sugar alcohols are not metabolized by oral bacteria, and so they do not contribute to tooth decay. Sugar alcohols Sugar substitutes. Mannitol Sorbitol Galactitol Iditol. Wikimedia Alconoles has media related to Sugar alcohols. 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.

Both disaccharides and monosaccharides can form sugar alcohols; however, sugar alcohols derived from disaccharides e.

As a group, sugar alcohols are not as sweet as sucroseand they have slightly less food energy than sucrose. Erythritol on the other hand is obtained by fermentation of glucose and sucrose. Retrieved 6 January Sugar alcohols do not contribute to tooth decay. They have one OH group attached poliloes each carbon. They are used widely in the food industry as thickeners and sweeteners.

With continued use, most people develop a degree of tolerance to sugar alcohols and no longer experience these symptoms. They are further differentiated by the relative orientation stereochemistry of these OH groups.

Retrieved January 6, Xylitol and sorbitol are popular sugar alcohols in commercial foods.
