PROBLEM TO BE SOLVED: To provide a simple method for manufacturing a low-cost beverage base material which prevents excessive intake of calories and sugar even in heavy drinking, capable of intake of a large amount of dietary fiber and vitamins with stable acidity and sweetness, inherent color impression, and good taste with flavor and a beverage having a wide range of concentration, which is made by adding clean water to the beverage base material at an appropriate ratio and agitating the mixture.SOLUTION: To a beverage base material 2, an auxiliary material 4 made of crushed vegetables or fruits for imparting color tone and flavor to the beverage base material is added in a proportion of 3 to 8 wt.% and mixed. Sugar 3 in a proportion of 45 to 55 wt.% relative to the total weight of the mixture is added and mixed. The mixture is well boiled to form a beverage base material 5 having viscosity and solubility in water, with a water content of 30 to 40%. The beverage base material is mixed and agitated with clean water 6, so as to have a water content of 50 to 90% through dissolution and dilution.COPYRIGHT: (C)2015,JPO&INPIT【課題】多量の飲用でもカロリーや糖分の過剰摂取とならず且食物繊維やビタミン類の多量の摂取と、安定した酸味と甘味並びに特有の色感と風味による旨さに優れた飲料基礎材を簡便且安価に形成するとともに、その飲料基礎材に清浄水を適宜割合で撹拌混合することにより、広範囲に濃縮度の異る飲料を提供する。【解決手段】ルバーブからなる飲料基材2若しくはこの飲料基材に特有の色調や風味を付与する野菜若しくは果物を破砕してなる飲料副素材4を3乃至8重量%割合で混合し、且この全体重量に対し45乃至55重量%割合の砂糖3を混合し煮熟せしめて粘網性と加水溶解性を有し水分率が30乃至40%の飲料基礎材5を形成し、この飲料基礎材に清浄水6を撹拌混合しその水分率を50乃至90%割合に溶解希釈させる。【選択図】図2
