An object of the present invention is to improve a distinctive strange taste (particularly bitterness remaining in the mouth) of a conventional low-calorie food or drink, particularly an edible product (a food or drink) having low calories obtained by replacing part or most of the sugar or isomerized sugar to be added by a high-intensity sweetener. Provided are a composition for improving a taste of a high-intensity sweetener, a method of improving a taste of an edible product containing a high-intensity sweetener, and an edible product in which a taste of a high-intensity sweetener is improved, each of which is characterized by containing or using an isomerized sugar and a rare sugar such that the rare sugar is contained or used in an amount of from 1 to 150 parts by mass based on 100 parts by mass of the isomerized sugar.本發明提供一種對於高甜度甜味料之味道呈現改良組成物及其應用。本發明對現有的低熱量飲食品，特別是藉由以高甜度甜味料取代應當添加的砂糖和異構化糖的一部分或者幾乎全部，以改良可實現低熱量的可食性製品(飲食品)所具有的特殊異味(特別是口中殘留的苦味)。對於高甜度甜味料之味道呈現改良組成物、含有高甜度甜味料的可食性製品之味道呈現改良方法、以及高甜度甜味料的味道呈現經改良的可食性製品，其特徵為，相對於異構化糖100質量份以稀有糖1~150質量份的比例含有異構化糖以及稀有糖。
