Abstract

Provided is a coffee beverage, including the following components (A), (B), and (C): (A) at least one selected from the group consisting of catechol and pyrogallol; (B) 3,4-dicaffeoyl-1,5-quinolactone; and (C) chlorogenic acids, in which a ratio of a total peak area of the component (A) to a peak area of the component (B), ((A)/(B)), as determined by liquid chromatography-time of flight mass spectrometry (LC-TOF/MS) of the coffee beverage, is from 0 to 2.0, and in which a content of the component (C) in the coffee beverage is from 0.05 to 2% by mass.

First claim

1 - 14 . (canceled)

15 . A coffee beverage, comprising components (A), (B), and (C):
(A) at least one selected from the group consisting of catechol and pyrogallol; (B) 3,4-dicaffeoyl-1,5-quinolactone; and (C) a chlorogenic acid, wherein a ratio of a total peak area of the component (A) to a peak area of the component (B), ((A)/(B)), as determined by liquid chromatography-time of flight mass spectrometry (LC-TOF/MS) of the coffee beverage, is from 0 to 2.0, wherein a content of the component (A) in the coffee beverage is from 1 to 10 ppm by mass, wherein a content of the component (C) in the coffee beverage is from 0.05 to 2% by mass, and wherein a Brix is from 0.8 to 3.0.

16 . The coffee beverage according to claim 15 , wherein the ratio of the total peak area of the component (A) to the peak area of the component (B), ((A)/(B)), as determined by LC-TOF/MS, is from 0.001 to 1.0.

17 . The coffee beverage according to claim 15 , wherein a content of catechol as the component (A) is 8 ppm by mass or less.

18 . The coffee beverage according to claim 15 , further comprising caffeine as a component (D), wherein a content of the component (D) in the coffee beverage is from 0.01 to 0.1% by mass.

19 . The coffee beverage according to claim 15 , wherein the coffee beverage has a pH of from 4.0 to 6.0.

20 . The coffee beverage according to claim 16 , wherein a content of catechol as the component (A) is 8 ppm by mass or less.

21 . The coffee beverage according to claim 20 , further comprising caffeine as a component (D), wherein a content of the component (D) in the coffee beverage is from 0.01 to 0.1% by mass.

22 . The coffee beverage according to claim 21 , wherein the coffee beverage has a pH of from 4.0 to 6.0.

23 . The coffee beverage according to claim 22 , which is a packaged coffee beverage.

24 . The coffee beverage according to claim 23 , which is a black coffee beverage.

25 . The coffee beverage according to claim 23 , which is a milk coffee beverage.

26 . The coffee beverage according to claim 24 , which is subjected to a heat sterilization.

27 . A method of improving retronasal aroma of a coffee beverage comprising components (A) and (B):
(A) at least one selected from the group consisting of catechol and pyrogallol; and (B) 3,4-dicaffeoyl-1,5-quinolactone, the method comprising adjusting a ratio of a total peak area of the component (A) to a peak area of the component (B), ((A)/(B)), as determined by liquid chromatography-time of flight mass spectrometry (LC-TOF/MS) of the coffee beverage, to from 0 to 2.0.

28 . The method according to claim 27 , further comprising adjusting a total content of the at least one selected from the group consisting of catechol and pyrogallol as the component (A) in the coffee beverage to from 1 to 10 ppm by mass or less.

29 . The method according to claim 27 , further comprising adjusting a content of catechol as the component (A) in the coffee beverage to 8 ppm by mass or less.

30 . The method according to claim 27 , further comprising adjusting a content of a chlorogenic acid as a component (C) in the coffee beverage to from 0.05 to 2% by mass.
