AZUCARES ALCOHOLES O POLIOLES PDF

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.

As a group, sugar alcohols are not as sweet as sucroseand they have slightly less food energy than sucrose. The table above presents the relative sweetness and food energy of the most widely used sugar alcohols. This property makes them popular sweeteners among diabetics and people on low-carbohydrate diets. By using this site, you agree to the Terms of Use and Privacy Policy. Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources.

They are white, water-soluble solids that can occur naturally or be produced industrially from sugars. This happens, for example, with the crystalline phase of sorbitolerythritolxylitolmannitollactitol and maltitol. Retrieved 6 January Ethylene glycol 2-carbon Glycerol 3-carbon Erythritol 4-carbon Threitol 4-carbon.

Studies have shown xylitol to be a deterrent to tooth decay. Despite the variance in food energy content of sugar alcohols, EU labeling requirements assign a blanket value of 2. Erythritol on the other hand is obtained by fermentation of glucose and sucrose. 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. Retrieved January 6, Unlike sugars, which tend to exist as rings, sugar alcohols do not.

However, like many other incompletely digestible substances, overconsumption of sugar alcohols can lead to bloatingdiarrhea and flatulence because they are not fully absorbed alcohkles the small intestine.

A Practical Handbookp. They are further differentiated by the relative orientation stereochemistry of these OH groups.

Some individuals experience such symptoms even in a single-serving quantity. Their flavor is like sucrose, and they can be used to mask the unpleasant aftertastes of some high intensity sweeteners.

From Wikipedia, the free encyclopedia. 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.

With continued use, most people develop a degree of tolerance to sugar alcohols and no longer experience these symptoms. Ullmann’s Encyclopedia of Industrial Chemistry. Consumption of sugar alcohols affects blood allcoholes levels, although much less than does sucrose comparing by glycemic index.

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.

They have one OH group attached to each carbon. Sugar alcohols Sugar substitutes. They are used widely in the food industry as thickeners and sweeteners. Most have five- or six-carbon chains, because they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively. Today, they are often obtained by hydrogenation of sugars, using Raney nickel catalysts.

Sugar alcohols are not metabolized by oral bacteria, oolioles so they do not contribute to tooth decay. Food containing xylitol increased bone density in rat studies.

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 rather sweet. Wikimedia Commons has media related to Sugar alcohols.
