A concentrated beverage composition for reconstitution is reduced in bitterness and astringency, adequate in both sweetness and sourness and improved in storage stability despite the inclusion of a high concentration of non-polymer catechins. The concentrated beverage composition for reconstitution
A concentrated beverage composition for reconstitution is reduced in bitterness and astringency, adequate in both sweetness and sourness and improved in storage stability despite the inclusion of a high concentration of non-polymer catechins. The concentrated beverage composition for reconstitution contains (A) from 0.5 to 25.0 wt % of non-polymer catechins, (B) a carbohydrate, and (C) a hydroxycarboxylic acid, and meets the following conditions (D) and (E) as well as at least one condition selected from the following conditions (F1), (F2) and (F3): (D) a content of gallic acid is lower than 0.6 wt %,(E) a percentage of non-epi-forms in the non-polymer catechins is from 5 to 25 wt %,(F1) a Brix degree is from 20 to 70, and when diluted with deionized water to give a non-polymer catechin concentration of 0.13 wt %, a pH is from 2.5 to 6.0,(F2) a solid content is not lower than 70.0 wt %, and when diluted with deionized water to give a non-polymer catechin concentration of 0.13 wt %, a pH is from 2.5 to 6.0, and(F3) an absorbance at 400 nm is smaller than 0.5 and a pH is from 2.5 to 6.0, when diluted with deionized water to give a non-polymer catechin concentration of 0.13 wt %.
