Abstract

Provided is a packaged beverage subjected to heat sterilization, including the following components (A) and (B): (A) 2.5 mass % or more of a protein; and (B) non-polymer catechins, the packaged beverage having: a mass ratio between the component (A) and the component (B), [(B)/(A)], of from 0.02 to 0.1; a viscosity of from 15 to 35 mPa·s; and a pH of 6.3 or more.

First claim

The invention claimed is:

1. A packaged beverage, comprising components (A) and (B):
(A) 2.5 mass % or more, based on the mass of the beverage, of a protein;
(B) a non-polymer catechin; and
(C) a thickener,
the packaged beverage having:
a mass ratio between component (A) and component (B), [(B)/(A)], of from 0.02 to 0.1;
a viscosity of from 15 to 35 mPa·s; and
a pH of 6.3 or more,
wherein said thickener is selected from the group consisting of alginic acid, agar, carrageenan, fucoidan, dextrin, maltodextrin, pectin, locust bean gum, xanthan gum, gum tragacanth, gellan gum, guar gum, carboxymethylcellulose, and hydroxyethylcellulose, or a salt thereof.

2. The packaged beverage according to claim 1 , wherein a content of the non-polymer catechin as component (B) is from 0.1 to 0.5 mass %, based on the mass of the beverage.

3. The packaged beverage according to claim 1 , wherein a content of the protein as the component (A) is from 3 to 10 mass %, based on the mass of the beverage.

4. The packaged beverage according to claim 1 , wherein the packaged beverage has a pH of from 6.3 to 7.5.

5. The packaged beverage according to claim 1 , wherein the protein of component (A) comprises casein protein as a component (F), and
wherein a ratio of the casein protein as a component (F) in the protein of component (A) is from 80 to 100 mass %.

6. The packaged beverage according to claim 1 , wherein a ratio of gallate forms in the non-polymer catechins as the component (B) is from 10 mass % to 50 mass %.

7. The packaged beverage according to claim 1 , wherein a mass ratio of the thickener as the component (C) to the protein as the component (A), [(C)/(A)], is from 0.01 to 5.

8. The packaged beverage according to claim 1 , wherein a content of the thickener as the component (C) in the packaged beverage is from 0.2 to 20 mass %.

9. The packaged beverage according to claim 1 , further comprising a sweetener as a component (D).

10. The packaged beverage according to claim 9 , wherein the sweetener is at least one member selected from the group consisting of a carbohydrate sweetener and a high-intensity sweetener.

11. The packaged beverage according to claim 10 , wherein
the sweetener as the component (D) is a carbohydrate sweetener, and a content of the carbohydrate sweetener in the packaged beverage is from 0.01 to 15 mass %.

12. The packaged beverage according to claim 10 , wherein
the sweetener as the component (D) is a high-intensity sweetener, and a content of the high-intensity sweetener in the packaged beverage is from 0.0001 to 5 mass %.

13. The packaged beverage according to claim 1 , further comprising caffeine as a component (E).

14. The packaged beverage according to claim 13 , wherein a content of the caffeine as the component (E), in terms of a mass ratio of the caffeine as the component (E) to the non-polymer catechins as the component (B), [(E)/(B)], is from 0.03 to 0.3.

15. The packaged beverage according to claim 1 , wherein a content of water present in the packaged beverage is from 60 to 95 mass %.

16. The packaged beverage according to claim 1 , wherein a median diameter of colloidal particles in the packaged beverage is 0.5 to 2.4 μm.

17. The packaged beverage according to claim 1 , wherein a variation (Δd), which is determined from a difference between the median diameter of colloidal particles in a beverage before heat sterilization and the median diameter of colloidal particles in a beverage after heat sterilization at 127° C. for 11 minutes, is 3 μm or less.

18. The packaged beverage according to claim 1 , wherein a change (ΔE) in color tone, which is determined from a difference between the L* value of a beverage before heat sterilization and the L* value of a beverage after heat sterilization at 127° C. for 11 minutes, is 30 or less.

19. The packaged beverage according to claim 1 , wherein the packaged beverage is subjected to heat sterilization.

20. The packaged beverage according to claim 1 , wherein, when 50 g of the packaged beverage subjected to heat sterilization is centrifuged at 20° C. and 6,000 rpm for 10 minutes and then measured for a mass of a precipitate, a ratio of the precipitate to the beverage is 5 mass % or less.
