The sweetness of an ingestible product or oral composition containing a sweetening sugar or sugar alcohol in relatively large quantities can be reduced and thereby the flavor enhanced by incorporation of at least one compound of the general formula (I) <IMAGE> (I) in which m represents 0.1; A represents a homocyclic or heterocyclic aromatic group with one or more rings; and B represents a hydrogen atom, a lower aliphatic group with 1-3 carbon atoms or a phenyl group; or, when m represents O, A and B together represent a bivalent homocyclic or heterocyclic aromatic group with two or more rings, or a methylidene group carrying as a substituent a homocyclic or heterocyclic aromatic group with one or more rings; an aromatic ring of A, or of A and B together, optionally carrying one to three substituents selected from lower alkoxy groups, lower alkyl or alkenyl groups, formyl or acetyl groups, hydroxy groups or acyloxy groups, and halogen atoms; C represents a hydrogen atom or an alkyl group or, when m represents O, a hydroxy or alkoxy group; D represents a oxygen or sulphur atom; X+ represents a hydrogen ion or another physiologically compatible cation; with the proviso that m represents 1 when S represents a substituted or unsubstituted phenyl group and B and C both represent hydrogen atoms; or when A represents an unsubstituted phenyl group, B represents an alkyl group and C represents a hydrogen atom. |
