PROBLEM TO BE SOLVED: To provide a carbohydrate and a foodstuff combined with the same by clarifying a carbohydrate having a special structure that can surely improve property of a foodstuff.SOLUTION: The carbohydrate for improving property of a foodstuff contains a carbohydrate, whose glucose-polymerization degree is at least 600, in a proportion of not more than 30% to the total carbohydrate and contains also a carbohydrate, whose glucose-polymerization degree is 200-600, in a proportion of 10% to 100% to the total carbohydrate, and a relative ratio of a part of a straight-chain sugar of at least 40-sugar against the total straight-chain sugar comprised of both main-chain and branched-chain in the carbohydrate other than a carbohydrate whose glucose-polymerization degree is less than 40 is 0.1-1.0%. A foodstuff containing the same, a sugar composition containing the carbohydrate and a natural starch, and a foodstuff containing the sugar composition are provided.COPYRIGHT: (C)2006,JPO&NCIPI【課題】 食品の物性改良を確実に達成できる特定構造の糖質を明らかにし、該糖質とこれを配合した食品等を提供すること。【解決手段】 全糖質中のグルコース重合度600以上に属する糖質の割合が30%以下で、かつ全糖質中のグルコース重合度200~600に属する糖質の割合が10%~100%であり、グルコース重合度40未満の糖質を除く糖質中の主鎖並びに分岐鎖を含む全直鎖糖に対する40糖以上の直鎖糖部分の相対的割合が0.1~1.0%であることを特徴とする食品物性改良用の糖質、該糖質が添加された食品、該糖質と天然澱粉を少なくとも含む糖組成物及び該糖組成物が添加された食品を提供する。【選択図】 図2
