Xylitol, ib txwm tshwm sim pentose qab zib cawv nrog cov tshuaj formula C5H12O5, yog dav siv nyob rau hauv cov khoom noj khoom haus kev lag luam raws li ib tug qab zib hloov vim nws qab zib nyob ze ntawm sucrose thiab nws cov calorie ntsiab lus. Ameslikas muab rho tawm los ntawm birch bark, nws yog tam sim no loj- ua los ntawm cov tshuaj synthesis los yog microbial fermentation. Raws li cov khoom noj khoom haus ntxiv, xylitol tsis yog tsuas yog muab cov khoom qab zib xwb tab sis kuj txhim kho kev ntxhib los mos ntawm cov zaub mov, ua lub luag haujlwm tseem ceeb hauv qab zib - cov khoom noj dawb.
Cov qauv molecular ntawm xylitol muaj tsib pawg hydroxyl (-OH), muab nws cov khoom tshwj xeeb physicochemical. Nws yog yooj yim soluble hauv dej (kwv yees li 160g / 100ml ntawm 20 degree) thiab me ntsis soluble hauv ethanol thiab methanol. Cov yam ntxwv no txiav txim siab nws cov solubility thiab stability nyob rau hauv cov zaub mov formulations. Piv nrog rau sucrose, xylitol muaj qis hygroscopicity, zoo tiv thaiv zaub mov los ntawm clumping thiab ncua lub txee lub neej.
