Los polioles, también llamados polialcoholes o alcoholes química se parece en parte a la de los azúcares y en parte a la de los alcoholes. Sugar alcohols are organic compounds, typically derived from sugars, that comprise a class of polyols. They are white, water-soluble solids that can occur. El Xylitol es un compuesto perteneciente a un grupo denominado “alcoholes de azúcar” o polioles. Se encuentra en la naturaleza en muchas.

Xylitol, un sustituto del azúcar que ayuda a prevenir las caries

Retrieved January 6, Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources. Sugar alcohols also called polyhydric alcoholspolyalcoholsalditols or glycitols are organic compoundstypically derived from sugarsthat comprise a class of polyols.

Wikimedia Commons has media related to Sugar alcohols. These results have generated interest in the sugar alcohol that would examine if it could be a human treatment for osteoporosis.

Polioles – Polioles

Sugar alcohols are not metabolized by oral bacteria, and so they do not contribute to tooth decay. Arabitol 5-carbon Alcoholew 5-carbon Ribitol 5-carbon. Sugar alcohols do not contribute to tooth decay. Retrieved 6 January As an exception, erythritol is actually absorbed in the small intestine and excreted unchanged through urine, so it contributes no calories even though it is poliopes sweet.

More than a million tons of sorbitol are produced in this way every year.

Xylitol and lactitol are obtained similarly. Consumption of sugar alcohols affects blood sugar levels, although much less than alconoles sucrose comparing by glycemic index. As a group, sugar alcohols are not as sweet as sucroseand they have slightly less food energy than sucrose.

Ullmann’s Poliolws of Industrial Chemistry. Xylitol and sorbitol are popular sugar alcohols in commercial foods.

Erythritol on the other hand is obtained by fermentation of glucose and sucrose. In commercial foodstuffs, sugar alcohols poliole commonly used in place of table sugar sucroseoften in combination with high intensity artificial sweeteners to counter the low sweetness. The sugar alcohols differ in chain length. Volemitol 7-carbon Isomalt carbon Maltitol carbon Lactitol carbon Maltotriitol carbon Maltotetraitol carbon Polyglycitol.

The Everything Diabetes Bookp. Mannitol Sorbitol Galactitol Iditol. Some individuals experience such symptoms even in a single-serving quantity. 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.

Sugar alcohol – Wikipedia

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. Despite the variance in food energy content of sugar alcohols, EU labeling requirements assign a blanket value of 2. A Practical Handbookp. They are further differentiated by the relative orientation stereochemistry alcoholea these OH groups.

Journal of thermal analysis.

The table above presents the relative azucaree and food energy of the most widely used sugar alcohols. Ethylene glycol 2-carbon Glycerol 3-carbon Erythritol 4-carbon Threitol 4-carbon Arabitol 5-carbon Xylitol 5-carbon Ribitol 5-carbon Mannitol 6-carbon Sorbitol 6-carbon Galactitol 6-carbon Fucitol 6-carbon Iditol 6-carbon Inositol 6-carbon; a cyclic sugar alcohol Volemitol 7-carbon Isomalt carbon Maltitol carbon Lactitol carbon Maltotriitol carbon Maltotetraitol carbon Polyglycitol.


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. They can however be dehydrated to give cyclic ethers, e. Unlike sugars, which tend to exist as rings, sugar alcohols do not. In other projects Wikimedia Commons. They have one OH group attached to each carbon. Ethylene glycol 2-carbon Glycerol 3-carbon Erythritol 4-carbon Threitol 4-carbon. Food containing xylitol increased bone density in rat studies.

Ethylene glycol [ citation needed ]. Most have five- or six-carbon chains, because they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively. This property makes them popular sweeteners among diabetics popioles people on low-carbohydrate diets.

With continued use, most people develop a degree of tolerance to sugar alcohols and no longer experience these symptoms.


Both disaccharides and monosaccharides can form sugar alcohols; however, sugar alcohols derived from disaccharides e. They are used widely in the food industry as pollioles and sweeteners. Uses authors parameter CS1 maint: Today, they are often obtained by hydrogenation of sugars, using Raney nickel catalysts. Studies have shown xylitol to be a deterrent to tooth decay.
