  @ Foodstuffs containing sweetness inhibitors having the general formula: wherein R7 is selected from the group consisting of hydrogen and C1-C3 alkyl, R. is selected from the group consisting of hydrogen and C1-C3 alkyl and wherein R9 is the group wherein R2, R3, R4, R. and R4 are independently selected from the group consisting of hydrogen, C1-C3 alkyl, C1-C3 alkoxy, C1-C2 hydroxyalkyl, hydroxy and COOH; and the non-toxic salts thereof. Disclosed is also a process for inhibiting the sweetness perception of a foodstuff.

  其中R7选自由氢和C1-C3烷基组成的组，R.选自由氢和C1-C3烷基组成的组，R9是R2、R3、R4、R.和R4独立地选自由氢、C1-C3烷基、C1-C3烷氧基、C1-C2羟烷基、羟基和COOH组成的组，以及它们的无毒盐。 还公开了一种抑制食品甜味感知的工艺。
