Xilitol in Tablet Candy
Xylitol is officially permitted as a food additive by the Ministry of Welfare in Japan on April 17, 1997.
The chromatogram is an analysis of xylitol in tablet candy. Asahipak NH2P-50 4E
column is quite useful for the analysis of sugar
alcohols including xylitol. NH2P-50 is a polymer-based amino column, and packed with the polyvinylalcohol gel bonded with polyamine. It is good for
quantitative analysis and can be washed with alkaline solvents.
2% aqueous solution of the sample was passed through a 0.45 micron filter,
and the same volume of acetonitrile was added.
