Abstract

The influence of harvest date on inulin chain length distribution, as wellas on the profile of glucose, fructose and sucrose of six different chicory cultivars previously not grown in the northern part of Europe was investigated. Inulin was extracted from both air- and freeze-dried chicory roots and analysed by means of high-performance anion-exchange chromatography withpulsed amperometric detection. Glucose, fructose and sucrose profiles werecalculated relative to the total content of these sugars and inulin. The highest weight average degree of polymerization (<(DP)over bar>(w)) for inulin was detected for the cultivars Bergues and Tilda (<(DP)over bar>(w) 17.6). The longest average inulin chains for all cultivars were found when harvesting chicory during mid and late October, and a significant decrease in <(DP)over bar>(w) was observed for all cultivars in November in connection with the weather turning colder. Concomitantly, sucrose levels increased significantly. Glucose and fructose levels were found to decrease until mid October and thereafter to increase slightly.
