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.

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. Yale New Haven Health. They are white, water-soluble solids that can occur naturally or be produced industrially from sugars. Studies have shown xylitol to be a deterrent to tooth decay. Wikimedia Commons has media related to Sugar alcohols.
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 also called polyhydric alcoholspolyalcoholsalditols or glycitols are organic compoundstypically derived from sugarsthat comprise a class of polyols.

Xylitol, un sustituto del azúcar que ayuda a prevenir las caries
L sugar alcohols differ in chain length. These results have generated interest in the sugar alcohol that would examine if it could be a human treatment for osteoporosis.

More than a million tons of sorbitol are produced in this way every year. Xylitol and lactitol are obtained similarly. Xylitol and sorbitol are popular sugar alcohols in commercial foods. A Practical Handbookp.
Both disaccharides and monosaccharides can form sugar alcohols; however, sugar alcohols derived from disaccharides e. Sugar alcohols Sugar substitutes. Consumption of sugar alcohols affects blood sugar levels, although much less than does sucrose comparing by glycemic index.
Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources. 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.
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.

Ethylene glycol [ citation needed ]. They are further differentiated by the relative orientation stereochemistry of these OH groups.
They can however be dehydrated to give cyclic ethers, e. Despite the variance in food energy content of sugar alcohols, EU labeling requirements assign a blanket value of 2. Views Read Edit View history. The Everything Diabetes Bookp. Sugar alcohols are not metabolized by oral bacteria, and so they do not contribute to tooth decay.

Some individuals experience such symptoms even in a single-serving quantity. This page was last edited on 30 Decemberat Their flavor is like sucrose, and they can be used to mask the unpleasant aftertastes of some high intensity sweeteners. Food containing xylitol increased bone density in rat studies. Today, they are often obtained by hydrogenation of sugars, using Raney nickel catalysts. Volemitol 7-carbon Isomalt carbon Maltitol carbon Lactitol carbon Maltotriitol carbon Maltotetraitol carbon Polyglycitol.
Unlike sugars, which tend to exist as rings, sugar alcohols do not. The cooling sensation is due to the dissolution of the sugar alcohol being an endothermic heat-absorbing reaction one with a strong heat of solution.

This property makes them popular sweeteners among diabetics and people on low-carbohydrate diets. They are used widely in the food industry as thickeners and sweeteners.
