-
, (2008/06/13)
Taste modifier comprising a flavone derivative as an active ingredient of the general formula (I): STR1 wherein R1, R3, R4, R6 and R8 are independently a methoxy group or an hydrogen atom, R2 and R7 are methoxy groups, and R5 is a methoxy group or an hydroxy group, and a method of modifying taste, comprising adding a taste-modifying effective amount of the flavone derivative (I) to a product used in a mouth or an orally ingestible product. Various factors associated with taste can be modified, for example, the derivative can enhance sourness, reduce saltiness, inhibit unpleasant lasting of sweetness, enhance refreshing flavor and its continuity, reduce flavor associated with acetic acid, and enhance body, deliciousness and savor associated with the combination of these tastes.
