Abstract: High-performance anion-exchange chromatography coupled with pulsed amperometric detection was optimized for determination of sugars and sugar alcohols in sugar-free food by recovery rates (88%~106%) of spiked samples and comparison with other type columns of CarboPac family. Determination results of propylene glycol, inositol, glycerol, D,L-xylitol, D-sorbitol, D-mannitol, galactitol, D-glucose, D-fructose, sucrose and maltose in fourteen samples are in wide linear range 0.2×10-6~40 ×10-6 with coefficients 99.8%~99.9%.

Key words: sugar-free and low-sugar food, sugars, sugar alcohols, HAEC-PAD
