Xylitol Chemical Properties,Uses,Production

Chemical Properties

White or almost white, crystalline powder or crystals.

Chemical Properties

The solubility of D-xylitol (D-xylopentan-1.2.3.4.5-pentaol) 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.

Uses

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.

Uses

sweetener and excipient, prevents acute otitis media

Uses

A polyol substrate for xylitol and sorbitol dehydrogenases.

Uses

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.

Uses

As oral and intravenous nutrient; in anticaries preparations.

Definition

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

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.

Safety Profile

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