The present invention provides a composition that, when ingested, is capable of releasing, in a sustained manner, a water-soluble taste component contained therein and allows the taste to be felt over a longer period of time than conventionally. Provided is a composition that comprises a gum base at least containing a rubber component and a water-soluble taste component, and that is characterized in that the product between the numerical value of the contained amount (wt%) of the rubber component and that of the contained amount (wt%) of the gum base in the composition results in 160.0-600.0.依據本發明可提供一種組成物，其於嚼食時可持續釋放組成物中的水溶性呈味成分、且較以往可歷經更長時間來感受呈味。本發明的組成物，其至少包含含有橡膠成分的膠基質與水溶性呈味成分，其特徵係前述組成物中的前述膠基質的含量(重量%)與前述橡膠成分的含量(重量%)的數值乘積為160.0以上600.0以下。
