PROBLEM TO BE SOLVED: To provide a taste improver for a sweetener having high sweetness, capable of effectively suppressing characteristic disagreeable aftertaste of the sweetener having high sweetness with a small addition amount without changing original taste and flavor of foods, drinks or oral hygiene products.SOLUTION: Characteristic disagreeable aftertaste of a sweetener having high sweetness is suppressed and tastes of foods, drinks or oral hygiene products are improved by adding at least one kind selected from a compound group consisting of dicarboxylic acid diester represented by the general formula 1, where n represents 0 or an integer of 1 to 8, R represents a methyl group or an ethyl group, a bond between the carbon atoms may either be a single bond or a double bond when n is 2, dimethyl carbonate and diethyl carbonate to foods, drinks or oral hygiene products containing high-sweetness sweetener.COPYRIGHT: (C)2014,JPO&INPIT【課題】飲食品又は口腔衛生製品の本来の風味を変化させることなく、高甘味度甘味料特有の不快な後味を少ない添加量で効果的に抑制する高甘味度甘味料の呈味改善剤を提供する。【解決手段】一般式1【化1】(式中、nは0又は1~8の整数を、Rはメチル基またはエチル基を表し、nが2のときは当該炭素間の結合は単結合と二重結合のいずれでもよい)で示されるジカルボン酸ジエステル、炭酸ジメチル、炭酸ジエチルからなる化合物群から選ばれる少なくとも1種を、高甘味度甘味料を含有する飲食品又は口腔衛生製品に添加することにより、高甘味度甘味料に特有の不快な後味が効果的に抑制され、飲食品や口腔衛生製品の呈味を改善することができる。【選択図】 なし
