Indigestible dextrin is a water-soluble dietary fiber made by hydrolyzing heat-treated potato starch by amylase, removing indigestible components from non-decomposed parts, desalting, decolorizing and adjusting. Dextrin, which is constructed by the sugar D-glucose, is a safe food material due to its long history of use as a food. In fact, it is categorized as a very safe food material that has no need for a maximum quantity of consumption per day to be set by FAO/WHO. Furthermore, it has been ascertained that indigestible dextrin does not prevent the absorption of minerals.
Since indigestible dextrin is excellent not only in safety but physical properties such as low viscosity, low sweetness, stability and preservability against heat or acid, there is a wide range of potential food applications. The physical function has also been examined, and in the effect against intestinal disorders and the blood sugar regulation effect, indigestible dextrin is used as a component for which certain health claims are allowed by the Ministry of Health, Labour and Welfare.
Regarding the effect against intestinal disorders, health claims such as "This product supplies lacking dietary fiber and helps regulate GI condition" or "This product is good for people concerned about GI condition" are permitted. For the blood sugar regulation effect, health claims such as "This product moderates the absorption of sugars and so is helpful for people concerned about their blood sugar level" or "This product is helpful for people concerned about their blood sugar level to improve their eating habit" can be used. Furthermore, the suppressive effects of serum cholesterol or neutral fat also apply as effects of a material of Foods for Specified Health Use.
