Claim:
A flavour composition, comprising at least 0.1 wt. % of flavouring substances and between 0.001 and 80 wt. % of: one or more first taste improving substances and optionally one or more second taste improving substances each independently according to formula (I) and/or edible salts thereof: R 1 —CR 7 (OR 4 )—CO—NR 2 —CR 8 R 3 —X—OR 5 (I) wherein: X represents a covalent bond; C 1 -C 5 alkyl or C 2 -C 5 alkenyl, each optionally substituted with 1-4 substituents selected from hydroxyl, C 1 -C 3 alkyl and C 1 -C 3 alkenyl; R 1 and R 7 independently represent hydrogen; or C 1 -C 8 alkyl, C 2 -C 8 alkenyl or C 3 -C 8 cycloalkyl, each optionally substituted with 1-8 substituents selected from hydroxyl, oxo, C 1 -C 3 alkyl; C 1 -C 3 alkenyl and C 1 -C 3 carboxyl; R 2 represents hydrogen; or C 1 -C 6 alkyl, C 2 -C 6 alkenyl, C 3 -C 6 cycloalkyl, C 3 -C 6 cycloalkenyl or C 1 -C 6 acyl, each optionally substituted with 1-6 substituents selected from hydroxyl, C 1 -C 3 alkyl and C 2 -C 3 alkenyl; R 3 and R 8 independently represent hydrogen; hydroxyl; or C 1 -C 8 alkyl, C 2 -C 8 alkenyl or C 2 -C 8 cycloalkyl, each optionally substituted with 1-8 substituents selected from hydroxyl, C 1 -C 3 alkyl and C 2 -C 3 alkenyl; R 4 represents hydrogen, C 1 -C 3 acyl or C 1 -C 3 alkyl; and R 5 represents hydrogen, C 1 -C 3 acyl, C 1 -C 3 alkyl, a phosphate group selected from mono-, di- and triphosphate, or a C 2 -C 5 carboxyacyl optionally further substituted with 1-3 substituents selected from hydroxyl, oxo, C 1 -C 3 carboxyl; provided that R 1 —CR 7 (OR 4 )—CO— does not represent a hexose or heptose sugar acid residue comprising more than 4 hydroxyl groups, further provided that for said first taste improving substance, R 5 represents a phosphate group selected from mono-, di- and triphosphate, or a C 2 -C 5 carboxyacyl optionally further substituted with 1-3 substituents selected from hydroxyl, oxo, C 1 -C 3 carboxy.
