  The present invention relates to aspartame-containing acidic beverages, and also relates to acidic beverages designed to prevent a storage-induced reduction in the sweetness of aspartame, which comprise a polymerized polyphenol (particularly a polymerized catechin). The present invention further relates to a method for preventing a storage-induced reduction in the sweetness of aspartame in aspartame-containing acidic beverages by using a polymerized polyphenol (particularly a polymerized catechin).

  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.
