Xylitol Chemical Properties,Uses,Production

Chemical Properties

White or almost white, crystalline powder or crystals.

Chemical Properties

The solubility of D-xylitol (D-xylopentan- in water is approximately 1,690 g/L at room temperature. Xylitol is stable under the common processing conditions of foods.
Xylitol is, depending on the concentration, similarly or slightly sweeter than sucrose and noncariogenic.
In the European Union, xylitol is approved as E 967 for a large number of food applications. In the United States, it is approved for use in foods following Good Manufacturing Practice and it is also approved in many other countries.

Chemical Properties

Xylitol occurs as a white, granular solid comprising crystalline, equidimensional particles having a mean diameter of about 0.4–0.6 mm. It is odorless, with a sweet taste that imparts a cooling sensation. Xylitol is also commercially available in powdered form, and several granular, directly compressible forms.


Xylitol is a polyhydric alcohol that is a natural sugar substitute com- mercially made from xylan-containing plants (birch) hydrolyzed to xylose. it is as sweet as sucrose, dissolves quickly, and has a negative heat of solution which results in a cooling effect. it has 24 kcal/g. it is used in chewing gum, throat lozenges, and chocolate.


sweetener and excipient, prevents acute otitis media


A polyol substrate for xylitol and sorbitol dehydrogenases.


As oral and intravenous nutrient; in anticaries preparations.


xylitol is a humectant and skin-conditioning agent. It acts as a humidifier, drawing moisture from the air for skin absorption. Some manufacturers also cite a soothing and anti-microbial action. Xylitol is a naturally occurring sugar in birch bark and a range of fibrous fruits and vegetables, including corn.


ChEBI: A pentitol (five-carbon sugar alcohol) having meso-configuration, being derived from xylose by reduction of the carbonyl group.

Production Methods

Xylitol occurs naturally in many fruits and berries, although extraction from such sources is not considered to be commercially viable. Industrially, xylitol is most commonly derived from various types of hemicellulose obtained from such sources as wood, corn cobs, cane pulp, seed hulls, and shells. These materials typically contain 20–35% xylan, which is readily converted to xylose (wood sugar) by hydrolysis. This xylose is subsequently converted to xylitol via hydrogenation (reduction). Following the hydrogenation step, there are a number of separation and purification steps that ultimately yield high-purity xylitol crystals. The nature of this process, and the stringent purification procedures employed, result in a finished product with a very low impurity content. Potential impurities that may appear in small quantities are mannitol, sorbitol, galactitol, or arabitol.
Less commonly employed methods of xylitol manufacture include the conversion of glucose (dextrose) to xylose followed by hydrogenation to xylitol, and the microbiological conversion of xylose to xylitol.

Biotechnological Production

Xylitol is mostly produced by chemical hydrogenation of xylose which is obtained by hydrolysis of xylans of plants such as birch and beech trees, corn cobs, bagasse, or straw, but also by fermentation of xylose, for example, using Candida species. Xylose, especially for hydrogenation, requires a high purity. It may be obtained from wood extracts or pulp sulfite liquor, a waste product of cellulose production, by fermentation with a yeast that does not metabolize pentoses. Some strains of S. cerevisiae, Saccharomyces fragilis, Saccharomyces carlsbergensis, Saccharomyces pastoanus, and Saccharomyces marxianus are suitable for this purpose.
Hydrolysates of xylan-rich material are often treated with charcoal and ionexchangers to remove by-products causing problems in hydrogenation or fermentation.
Many studies of xylitol production by fermentation have been published. Different organisms, substrates, and conditions were investigated. As the starting material, xylose or xylose in combination with glucose was used. Fermentation was carried out in batch reactors as well as continuously.
Among the variations studied was cell recycling in a submerged membrane bioreactor for C. tropicalis with a high productivity of 12 g/Lh, a conversion rate of 85 % and a concentration of 180 g/L. Many studies addressed the immobilization of cells such as S. cerevisiae, C. guilliermondii, or D. hansenii, especially with calcium alginate.

Pharmaceutical Applications

Xylitol is used as a noncariogenic sweetening agent in a variety of pharmaceutical dosage forms, including tablets, syrups, and coatings. It is also widely used as an alternative to sucrose in foods and as a base for medicated confectionery. Xylitol is finding increasing application in chewing gum, mouthrinses, and toothpastes as an agent that decreases dental plaque and tooth decay (dental caries). Unlike sucrose, xylitol is not fermented into cariogenic acid end products and it has been shown to reduce dental caries by inhibiting the growth of cariogenic Streptococcus mutans bacteria. As xylitol has an equal sweetness intensity to sucrose, combined with a distinct cooling effect upon dissolution of the crystal, it is highly effective in enhancing the flavor of tablets and syrups and masking the unpleasant or bitter flavors associated with some pharmaceutical actives and excipients.
In topical cosmetic and toiletry applications, xylitol is used primarily for its humectant and emollient properties, although it has also been reported to enhance product stability through a combination of potentiation of preservatives and its own bacteriostatic and bactericidal properties.
Granulates of xylitol are used as diluents in tablet formulations, where they can provide chewable tablets with a desirable sweet taste and cooling sensation, without the ‘chalky’ texture experienced with some other tablet diluents. Xylitol solutions are employed in tablet-coating applications at concentrations in excess of 65% w/w.Xylitol coatings are stable and provide a sweet-tasting and durable hard coating.
In liquid preparations, xylitol is used as a sweetening agent and vehicle for sugar-free formulations. In syrups, it has a reduced tendency to ‘cap-lock’ by effectively preventing crystallization around the closures of bottles. Xylitol also has a lower water activity and a higher osmotic pressure than sucrose, therefore enhancing product stability and freshness. In addition, xylitol has also been demonstrated to exert certain specific bacteriostatic and bactericidal effects, particularly against common spoilage organisms.
Therapeutically, xylitol is additionally utilized as an energy source for intravenous infusion therapy following trauma.

Safety Profile

Very low toxicity by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes. A sugar.


Xylitol is used in oral pharmaceutical formulations, confectionery, and food products, and is generally regarded as an essentially nontoxic, nonallergenic, and nonirritant material.
Xylitol has an extremely low relative glycemic response and is metabolized independently of insulin. Following ingestion of xylitol, the blood glucose and serum insulin responses are significantly lower than following ingestion of glucose or sucrose. These factors make xylitol a suitable sweetener for use in diabetic or carbohydrate-controlled diets.
Up to 100 g of xylitol in divided oral doses may be tolerated daily, although, as with other polyols, large doses may have a laxative effect. The laxative threshold depends on a number of factors, including individual sensitivity, mode of ingestion, daily diet, and previous adaptation to xylitol. Single doses of 20–30 g and daily doses of 0.5–1.0 g/kg body-weight are usually well tolerated by most individuals. Approximately 25–50% of the ingested xylitol is absorbed, with the remaining 50–75% passing to the lower gut, where it undergoes indirect metabolism via fermentative degradation by the intestinal flora.
An acceptable daily intake for xylitol of ‘not specified’ has been set by the WHO since the levels used in foods do not represent a hazard to health.

Xylitol is stable to heat but is marginally hygroscopic. Caramelization can occur only if it is heated for several minutes near its boiling point. Crystalline material is stable for at least 3 years if stored at less than 65% relative humidity and 25℃. Milled and specialized granulated grades of xylitol have a tendency to cake and should therefore be used within 9 to 12 months. Aqueous xylitol solutions have been reported to be stable, even on prolonged heating and storage. Since xylitol is not utilized by most microorganisms, products made with xylitol are usually safe from fermentation and microbial spoilage.
Xylitol should be stored in a well-closed container in a cool, dry place.


Xylitol is incompatible with oxidizing agents.
