PROBLEM TO BE SOLVED: To provide an effective agent for inhibiting the rise in blood glucose level by using a safe food material to be taken ordinarily as a food.SOLUTION: The agent for inhibiting the rise in blood glucose level contains palatinose as an active component and the ratio of &alpha-1,6-glucosyl bond based on the total bonds between the constituting saccharides is &ge0% and <50%. The agent is taken simultaneously with or before or after the take of a carbohydrate to inhibit the rise in blood glucose level caused by the taking of the carbohydrate.COPYRIGHT: (C)2007,JPO&INPIT【課題】通常食品として摂取される安全な食品素材を用いた、効果的な血糖値上昇抑制剤を提供する。【解決手段】パラチノースを有効成分とし、構成糖同士の結合全体に対するα-1,6-グルコシル結合の割合が0%以上50%未満である炭水化物の摂取と同時またはその前後に摂取させ、当該炭水化物の摂取に起因する血糖値上昇を抑制するための血糖値上昇抑制剤。【選択図】 なし
