It is intended to provide a carbonated beverage excelling in function as thirst-quenching beverage and taste through strengthening or sustaining of carbonate sensation peculiar to carbonated beverage (brisk intense stimulation and sensation at pass through the throat, brought about by carbon dioxide gas, and sensation of coolness (refreshing sensation) produced by a combination of carbon dioxide gas and flavor) which after opening, rapidly drops depending upon a combination of employed raw materials, such as fruit juice, sweetener, colorant and spice, and upon evaporation of carbon dioxide gas. The drop of carbonate sensation brought about depending upon a combination of raw materials, such as fruit juice and sweetener, can be relieved by adding to a carbonated beverage an additive for carbonated beverage comprising spilanthol or a spilanthol-containing plant extract or plant essential oil as an active ingredient. Further, the addition would help inhibit drop of carbonate sensation brought about depending upon evaporation of carbon dioxide gas after opening and would help retain the taste and function as function as thirst-quenching beverage inherently to be had by carbonated beverage even after opening. |
