Method of inhibiting sweetness

An ingestible product comprising a sweetening sugar and a sweetness-reducing amount of at least one compound of the general formula (I) ##STR4## 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 individually represent a lower alkoxy group, phenoxy group or a lower alkyl or trifluoromethyl group;
• or two substituents R together represent an aliphatic chain linked to the phenyl ring at two positions directly or via an oxa-group;
• or one substituent R represents a hydroxy group while at least one other substituent R represents an alkoxy group;
• and X.sup.+ represents a physiologically acceptable cation.

A composition comprising sucrose or glucose in the form of a solid or syrup and a sweetness-reducing amount of at least one compound of the general formula (I) ##STR5## in which m represents 0 or 1, and then 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 individually represent a lower alkoxy group, phenoxy group or a lower alkyl or trifluoromethyl group;
• or two substituents R together represent an aliphatic chain linked to the phenyl ring at two positions directly or via an oxa-group;
• or one substituent R represents a hydroxy group while at least one other substituent R represents an alkoxy group;
• and X.sup.+ represents a physiologically acceptable cation.
