PROBLEM TO BE SOLVED: To provide a new peptide having a thick taste-imparting function and also a food imparted with the thick taste effectively by adding the peptide without damaging its flavor.SOLUTION: The peptides consisting of one or more sequences represented by the following sequence formula are found out to have the thick taste-imparting function. The sequence formula (I): Asp-Trp-Arg-Gly-Gly-Arg, the sequence formula (II): Asp-Trp-Arg-Gly-Gly-Arg-Thr, the sequence (III): Phe-Lys-Tyr, the sequence (IV): Val-Leu-Gly-Tyr, the sequence (V): Leu-Gly-Gln-Trp, the sequence (VI): Ala-Ile-Gly-Glu-Trp, the sequence (VII): Ile-Thr-Trp-Glu, the sequence (VIII): Val-Trp-Glu-Tyr, the sequence (IX): Phe-Asp-Trp, the sequence (X): Phe-Glu-Trp.COPYRIGHT: (C)2009,JPO&INPIT【課題】本発明は、厚味付与機能を有する新規ペプチドを提供することを課題とする。また本発明は、該ペプチドを添加することで風味を損なうことなく、効果的に厚味の付与された食品を提供することを課題とする。【解決手段】下記配列式で表される配列のいずれか1つまたは2つ以上からなるペプチドが厚味付与機能を有することを見出した。配列式(I)Asp-Trp-Arg-Gly-Gly-Arg配列式(II)Asp-Trp-Arg-Gly-Gly-Arg-Thr配列式(III)Phe-Lys-Tyr配列式(IV)Val-Leu-Gly-Tyr配列式(V)Leu-Gly-Gln-Trp配列式(VI)Ala-Ile-Gly-Glu-Trp配列式(VII)Ile-Thr-Trp-Glu配列式(VIII)Val-Trp-Glu-Tyr配列式(IX)Phe-Asp-Trp配列式(X)Phe-Glu-Trp【選択図】なし
