Xylitol is a 5-carbon sugar alcohol (or polyol) primarily known for its anti-cariogenic properties, sweetness comparable to sucrose, and high cooling effect (negative heat of solution). Preliminary studies have shown further medical benefits, with the most notable benefit a suppression of ear infections in small children. Crystalline xylitol typically does not flow well after storage - it has a tendency to clump due to its hygroscopicity. Another drawback has been compressibility in tablet applications. By itself, crystalline xylitol does not compress well, and alternatives have also not performed satisfactorily. SPI Polyols, Inc. recently introduced Xylogem® 90 and Xylogem® SD crystalline xylitol, two co-processed crystalline xylitol products with significantly improved flow properties and compressibility. Comparative data detailing these properties will be presented.
SPI has also introduced a liquid delivery form of xylitol, Sorbo® X-45 non-crystallizing sorbitol solution (75% solids) containing co-processed sorbitol and xylitol. This product contains 45% xylitol and 55% sorbitol on a dry basis, and represents an easier and more economical method of delivering xylitol into a varity of applications, including toothpaste, mouthwash, confectionery, nutritional bars, or baked products. Xylitol and sorbitol act synergistically in Sorbo X-45, resulting in an excellent humectant for shelf life extension. Data will be presented on its relative sweetness and textural benefits.
