US 6894199, Process for the production of xylitol
(2R,4S)-Pentane-1,2,3,4,5-pentol Xylitol used to denote sugar alcohols) is a sugar alcohol sweetener used as a sugar substitute. Xylitol has the formula (CHOH)3(CH2OH)2 and is an achiral isomer of pentane-1,2,3,4,5-pentol. Xylitol is roughly as sweet as sucrose with 33% fewer calories. Unlike other sweeteners, xylitol is actively beneficial for dental health, reducing caries to a third in regular use, and has been shown to reduce… Continue reading US 6894199, Process for the production of xylitol
