The present invention relates to edible orally delivered products, such as beverages, food products, confectioneries and chewing gum, which provide an enhanced perception of an active substance, such as a sweetener. More specifically, some embodiments provide potentiator compositions, which include at least one active substance and at least one sweetness modifier. The sweetness modifier may increase sucrose equivalence, increase the perception of sweet flavor upon consumption, decrease the perception of an aftertaste, or extend the time periods of sweetness onset, sweetness peak or sweetness decay.
