PROBLEM TO BE SOLVED: To provide, in a thirsty-proofness beverage that is routinely drunken and is comparably easy to ingest a specified amount every day, a process for producing a grain tea in which the lack of flavor balance resulting from the addition of dietary fiber and the deterioration in property are suppressed, and to provide a grain tea property deterioration suppression method.SOLUTION: A dietary fiber-containing grain tea beverage production process comprises: a step of mixing a grain ingredient and a dietary fiber in a pH adjusted solvent such that the ratio of dietary fiber to grain ingredient (dietary fiber/grain ingredient) is 0.02 to 3.00, to obtain a mixed liquid A and a particle size adjustment step of adjusting the average particle size of insoluble particles in the mixed liquid A to 10 to 70 μm, thereby the lack of flavor balance resulting from the addition of dietary fiber and the deterioration in property are suppressed.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】日常的に飲用されており、毎日所定量を摂取することが比較的容易な止渇性飲料において、食物繊維の添加による香味バランスの欠如及び性状劣化を抑制した穀物茶の製造方法並びに穀物茶の性状劣化抑制方法を提供することを目的とする。【解決手段】pH調整下の溶媒中で穀物原料に対する食物繊維の比率(食物繊維/穀物原料)が0.02~3.00になるように混合し、混合液Aを得る工程と、混合液Aにおける不溶性粒子の平均粒子径を10~70μmに調整する粒度調整工程とを備えることによって、食物繊維の添加による香味バランスの欠如及び性状劣化が抑制される。【選択図】なし
