Ion Chromatographic Separation and Determination of Inulenin in Tuber of Jerusalem Artichoke and Chicory Root with Pulsed Amperometric Detection

A laboratory method of separation and determination of inulenin in root tuber and stem tuber of Jerusalem artichoke or chicory by ion chromatography with pulsed amperometric detection was established. Detection limit of 1 mg·L-1 was found for the target sugar. Differentiation of fructose homologues having structural differences of one monosaccharide unit was achieved by the proposed method.
