The present invention aims to provide a food or drink having an improved sharpness in an aftertaste without reduction in its peak sweetness. According to the present invention, a food or drink containing a sweetener in which sweetness persisting as an unpalatable aftertaste is suppressed, and which retains a nearly intact degree of sweetness of the sweetener at its peak can be obtained by adding a polymerized polyphenol, particularly, a polymerized catechin, which is a polymerized polyphenol derived from tea, to the food or drink.本發明之目的在提供不降低甜味尖峰之甜味度且能改善回味的鋒利之飲食品。據本發明藉添加聚合多酚,特別是來源於茶之聚合多酚之聚合兒茶酸,幾乎不降低甜味料之甜味尖峰處之甜味度,且能抑制回味中在啫好上認為不好的甜味的持續性,提供經改善呈味的飲食品。
