Claim 9

The foodstuff composition of claim 1 wherein said foodstuff is selected from the group consisting of a soft frozen dessert, an infused vegetable, an instantized rice and a dairy or non-dairy whipped topping.

Claim 10

A process for inhibiting the sweetness perception of a foodstuff, said process comprising adding to a foodstuff containing a sweetener, a a sweetness inhibiting compound, said compound being present in an amount effective to inhibit the sweetness perception in said foodstuff and having the general formula: ##STR7## wherein R 7 is selected from the group consisting of hydrogen and C 1 -C 3 alkyl, R 8 is selected from the group consisting of hydrogen and C 1 -C 3 alkyl and wherein R 9 is the group ##STR8## wherein R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of hydrogen, C 1 -C 3 alkyl, C 1 -C 3 alkoxy, C 1 -C 2 hydroxyalkyl, hydroxy and COOH; and the non-toxic salts thereof.

Claim 11

A process for inhibiting the sweetness perception of a foodstuff, said process comprising adding to a foodstuff containing a sweetener, a a sweetness inhibiting compound, said compound being present in an amount effective to inhibit the sweetness perception in said foodstuff and having the general formula: ##STR7## wherein R 7 is selected from the group consisting of hydrogen and C 1 -C 3 alkyl, R 8 is selected from the group consisting of hydrogen and C 1 -C 3 alkyl and wherein R 9 is the group ##STR8## wherein R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of hydrogen, C 1 -C 3 alkyl, C 1 -C 3 alkoxy, C 1 -C 2 hydroxyalkyl, hydroxy and COOH; and the non-toxic salts thereof.

Claim 12
