Abstract
Abstract The sweetness of an ingestible product containing a sweetening sugar or sugar alcohol in large quantities can be reduced by incorporating therein a sweetness-reducing amount of at least one compound of the general formula: <IMAGE> (I) in which m represents 0 or 1, and when m represents 0, n represents 1, 2 or 3, and p represents 1, 2, 3 or 4, and when m represents 1, n represents 1 or 2 and p represents 0, 1, 2, 3 or 4; the substituents R, which may be the same or different, each represent a lower alkoxy group, e.g. with 1 to 5 carbon atoms, phenoxy group or a lower alkyl or trifluoromethyl group; and/or two substituents R together represent an aliphatic chain linked to the phenyl ring at two positions, either directly or via an oxa-group, e.g. an alkylenedioxy, alkenylenedioxy, alkylenoxy or alkenylenoxy group; and/or one substituent R represents a hydroxy group while at least one other substituent R represents an alkoxy group; and X+ represents a physiologically acceptable cation.
