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.

Sugar alcohols are not metabolized by oral bacteria, and so they do not contribute to tooth decay. 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.
Xylitol, un sustituto del azúcar que ayuda a prevenir las caries
Unlike sugars, which tend to exist as rings, sugar alcohols do not. Mannitol Sorbitol Galactitol Iditol. Xylitol and lactitol are obtained similarly.
Xylitol and sorbitol are popular sugar alcohols in commercial foods. The table above presents the relative sweetness and food energy of the most widely used sugar alcohols.
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. These results have generated interest in the sugar alcohol that would examine if it could be a human treatment for osteoporosis. Most have five- or six-carbon chains, because they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively.
Erythritol azucars the other hand is obtained by fermentation of glucose and sucrose. The Everything Diabetes Bookp. They are white, water-soluble solids that can azkcares naturally or be produced industrially from sugars.

This happens, for example, with the crystalline phase of sorbitolerythritolxylitolmannitollactitol and maltitol. Ullmann’s Encyclopedia of Industrial Chemistry. Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources. With continued use, most people develop a degree of tolerance to sugar alcohols and no longer experience these symptoms.
Wikimedia Commons has media related to Sugar alcohols. More than a million tons of sorbitol are produced in this way every year. 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.

They can however be dehydrated to give cyclic ethers, e. Ethylene glycol [ citation needed ].

Today, they are often obtained by hydrogenation of sugars, using Raney nickel catalysts. Views Read Edit View history. Ethylene glycol 2-carbon Glycerol 3-carbon Erythritol 4-carbon Threitol 4-carbon.
