A composition comprising an eatable having at least one taste selected from bitter and metallic, and at least one tastand in a substantially tasteless amount of about 0.0000001 to about 300% by weight, based on the weight of the eatable, which amount is sufficient to reduce said at least one bitter
A composition comprising an eatable having at least one taste selected from bitter and metallic, and at least one tastand in a substantially tasteless amount of about 0.0000001 to about 300% by weight, based on the weight of the eatable, which amount is sufficient to reduce said at least one bitter and metallic taste, said tastand being selected from the group consisting of compounds which are substantially tasteless in the amount used and have the structure: [Figure] U-1 wherein A is selected from the group consisting of O, S, and C; when A is C, n is 1; and when A is O or S, n is zero; R1, R2, R3, R4, R5, R6, R7,R8, R9, R10, R11, and R12 are independently selected from the, group consisting of H, hydroxy, nitro, cyano, halogen, COOH, SO3H, CH2SO2NH2, trifluoroacetyl, an acid group of the structure ZOqHr wherein Z is an element selected from the group consisting of carbon, sulfur, boron or phosphorus, q is an integer from 2 to 3 and r is an integer from 1 to 3; and an O, S, N or phosphorylated glycoside, where the glycoside is selected from the group consisting of monosaccharides, disaccharides, trisaccharides, and oligosaccharides all of which saccharides may be substituted; and the following groups which may be substituted or unsubstituted: amino, alkyl, alkoxy, aryl, alkylene, aminoacyl, aryloxy, aralkoxy, acyl, arylacyl, benzoyl, alkylamino, dialkylamino, trialkylamino, carbonates, alkylcarbonates, arylcarbonates, acylamino, quanidino, alkylguanidino, acylguanidino, arylguanidino, alkylurethanes, arylurethanes, ureas, alkylureas, CHO, COCH3, COCH3, CH2CHO, CH2COOH, COOCH3, OCOCH3, CONH2, NHCHO, SCH3, SCH2CH3, CH2SCH3, SO2NH2, SO2CH3, CH2SO3H, cycloalkyl, heterocyclic, polycyclic, arylureas, carboxylic acid ester, carboxamide, N-alkyl carboxamide, di-alkyl carboxamides, and wherein any two substituents taken together can be an aliphatic chain linked to a phenyl ring at one or more positions either directly via a carbon atom or indirectly via an oxygen, nitrogen or sulfur atom to form a ring structure; OR13, NH－R13, N－(R13)2, and S－R13, where R13 is selected from the group consisting of H, trifluoroacetyl; and substituted or unsubstituted alkyl, dialkyl, aralkyl, aryl, diaryl, acyl, cycloalkyl, benzoyl, alkyloxycarbonyl, aryloxycarbonyl, alkylaminocarbonyl, arylaminocarbonyl, amidines, alkylamidines, arylamidines, a monosaccharide, a disaccharide, a trisaccharide, an oligosaccharide, phosphorylated saccharides, arylacyl, alkylene, heterocyclic and polycyclic;; any two R substitutents may be dehydrated to form an anhydride linkage; or any two R substituents may together form a cyclic structure; where CH－CH or CH2－CH2 bonds exist the level of unsaturation may be increased by removing one or more hydrogen atoms from the carbon atoms participating in the CH－CH or C2－CH2. bond; and physiologically acceptable salts of all of the foregoing.
