Uses authors parameter CS1 maint: 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.

Ethylene glycol [ citation needed ]. This happens, for example, with the crystalline phase of sorbitolerythritolxylitolmannitollactitol and maltitol. As a group, sugar alcohols are not as sweet as sucroseand they have slightly less food energy than sucrose.

Despite the variance in food energy content of sugar alcohols, EU azjcares requirements assign a blanket value of 2. Wikimedia Commons has media related to Sugar alcohols. Views Read Edit View history.

Most have five- or six-carbon chains, because they are derived from pentoses five-carbon sugars and hexoses six-carbon sugarsrespectively.

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 are used widely in the food industry as alvoholes and sweeteners. Xylitol and lactitol are obtained similarly. With continued use, most people develop a degree of tolerance to sugar alcohols and no longer experience these symptoms.

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. Ullmann’s Encyclopedia of Industrial Chemistry.

Unlike sugars, which tend to exist as rings, sugar alcohols do not. Erythritol on the other hand is obtained by fermentation of glucose and sucrose.

Their flavor is like sucrose, and they can be used to mask the unpleasant aftertastes of some high intensity sweeteners. Sugar alcohols are not metabolized by oral bacteria, and so they do not contribute to tooth decay. However, like many other incompletely digestible substances, overconsumption of sugar alcohols can lead to bloatingdiarrhea and flatulence because they alcoho,es not fully absorbed in the small intestine.

Sugar alcohols occur naturally and at one time, mannitol was obtained from natural sources. These results have generated interest in the sugar alcohol that would examine if it could be a human treatment for osteoporosis.
