PROBLEM TO BE SOLVED: To provide a water-soluble dietary fiber-containing solution reduced in a coloring degree and high in storage stability.SOLUTION: Provided is a method for producing a water-soluble dietary fiber-containing solution reduced in coloring, including a process where water-soluble dietary fiber and non-dietary fibrous monosaccharide and/or oligosaccharide are held in a solution. Also provided is a method for producing a water-soluble dietary fiber-containing solution reduced in coloring where the solid content concentration of a solution is 20-85 mass%, the solution is held under the temperature conditions of 25-70°C, or the solid content ratio between the water-soluble dietary fiber and the non-dietary fibrous monosaccharide and/or oligosaccharide lies in the range of 2:8 to 9:1. Also provided is a coloring reduction agent for a water-soluble dietary fiber including non-dietary fibrous monosaccharide and/or oligosaccharide as effective components, and a coloring reduction method for a water-soluble dietary fiber-containing solution.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】着色度が低減され、保存安定性の高い水溶性食物繊維含有溶液の提供。【解決手段】水溶性食物繊維と、非食物繊維性の単糖及び/又はオリゴ糖と、を溶液中で保持する工程を含んでなる着色が低減された水溶性食物繊維含有溶液の製造方法。溶液の固形分濃度が20~85質量%、溶液を25~70℃の温度条件下で保持、又は、水溶性食物繊維と、非食物繊維性の単糖及び/又はオリゴ糖と、の固形分比率が2:8~9:1の範囲である着色が低減された水溶性食物繊維含有溶液の製造方法。非食物繊維性の単糖及び/又はオリゴ糖を有効成分として含む水溶性食物繊維の着色低減剤及び水溶性食物繊維含有溶液の着色低減方法。【選択図】なし
