Utilisation of Jerusalem Artichoke tubers in food industry brings many benefits, because the inulin content is only partly digestible, and that part dissolves into fruc-tose. Fructose will not elevate serum glucose, so it does not need insulin, and that is why it is applicable for usage in diabetic products. The Jerusalem Artichoke concentrate can be used as a natural sweetener. It has nice taste, mildly sweetish flavour. The Jerusalem Artichoke concentrate (liquid fructose) is applicable for re-placement of sucrose in fruit conserves. It is possible to produce dried material, too, and products enriched with inulin.
