Patent ID: 8871288

Claim:
A method of imparting or intensifying an umami flavor comprising adding to a substance (a) one or more compounds selected from the group consisting of compounds of Formulae (I) and (ent-I) wherein in Formulae (I) and (ent-I) the following applies: the aromatic radical Ar is selected from the group consisting of: wherein the dotted line marks the bond linking the aromatic radical Ar to the adjacent carbonyl carbon atom in Formula (I) or (ent-I), and wherein R 1 and R 2 in the aromatic radicals A and B are selected independently of one another from the group consisting of H, OCH 3 , and COOCH 3 , or R 1 and R 2 are adjacent and jointly form an OCH 2 O group, and X in the aromatic radical C is O, and (b) optionally, one or more compounds selected from the group consisting of Formulae (II), (ent-II), (III), (ent-III), (IV), and (ent-IV): wherein Formulae (II), (ent-II), (III), (ent-III), (IV), and (ent-IV), have independently of one another one of the meanings specified for Formulae (I) and (ent-I), wherein the ratio by weight of (a) all of the compounds of Formulae (I) and (ent-I) to (b) all of the compounds of Formulae (II), (ent-II), (III), (ent-III), (IV) and (ent-IV), if present, is at least 90:10, thereby imparting or intensifying an umami flavor.
