PROBLEM TO BE SOLVED: To provide an activated carbon selection method capable of decreasing the content of 5-hydroxymethylfurfural in a liquid food and beverage.SOLUTION: Activated carbon capable of decreasing the content of 5-hydroxymethylfurfural in a liquid food and beverage can be selected using, as an index, a reduction rate of 4-methylimidazole at the time when caramel pigment solution prepared by diluting a specific caramel pigment five times with water and activated carbon in an amount of 2 mass% with respect to the solution are brought into contact with each other for one hour at 25°C.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】液体状飲食品中の5-ヒドロキシメチルフルフラールの含有量を低減できる活性炭の選抜方法の提供。【解決手段】水で特定のカラメル色素を5倍希釈したカラメル色素溶液と、該溶液に対して2質量%の活性炭とを25℃で1時間接触させたときの4-メチルイミダゾールの低減率を指標として、液体状飲食品中の5-ヒドロキシメチルフルフラールを低減できる活性炭を選抜できる。【選択図】なし
