Abstract

A method of producing a thickened carbonated beverage packed in a container, comprising: mixing an aqueous solution containing a first thickening agent and having a temperature of 0 to 35° C. with a second thickening agent insoluble in water in a temperature range of 0 to 35° C. but soluble in water at a temperature of 60° C. or more to obtain a stock liquid with the second thickening agent dispersed in the solution; dissolving carbon dioxide gas in the stock liquid to obtain a carbonated aqueous solution; filling a container with the carbonated aqueous solution and sealing the container to obtain the carbonated aqueous solution packed in the container; and heating the carbonated aqueous solution packed in the container such that the carbonated aqueous solution has a temperature of 60° C. or more to dissolve the second thickening agent in the solution.

First claim

What is claimed is:

1. A method of producing a thickened carbonated beverage packed in a container, the method comprising:
dissolving a first thickening agent which is soluble in water having a temperature of 0 to 35° C. in water having a temperature of 0 to 35° C. equal to or higher than a temperature at which the first thickening agent can dissolve, thereby obtaining an aqueous solution containing the first thickening agent and having a temperature of 0 to 35° C., wherein the aqueous solution containing the first thickening agent has a viscosity of 20 to 150 [mPa·s] when measured by an E-type viscometer according to JIS Z8803: 2011 under conditions of a temperature of 20° C. and a shear rate of 50/s;
mixing the aqueous solution containing the first thickening agent and having a temperature of 0 to 35° C. with a second thickening agent which is insoluble in water in a temperature range of 0 to 35° C. but soluble in water at a temperature of 60° C. or more, thereby obtaining a stock liquid in which the first thickening agent is dissolved and the second thickening agent is dispersed, wherein the stock liquid has a viscosity of 20 to 150 [mPa·s] when measured by an E-type viscometer according to JIS Z8803: 2011 under conditions of a temperature of 20° C. and a shear rate of 50/s;
dissolving carbon dioxide gas in the stock liquid, thereby obtaining a carbonated aqueous solution in which the first thickening agent is dissolved and the second thickening agent is dispersed;
filling a container with the carbonated aqueous solution and sealing the container, thereby obtaining the carbonated aqueous solution packed in the container wherein the first thickening agent is dissolved in the carbonated aqueous solution and the second thickening agent is dispersed in the carbonated aqueous solution; and
heating the carbonated aqueous solution packed in the container such that the carbonated aqueous solution has a temperature of 60° C. or more, thereby dissolving the second thickening agent in the carbonated aqueous solution.

2. The method according to claim 1 , wherein:
the first thickening agent is at least one selected from the group consisting of welan gum, guar gum, cold-water-soluble type of iota carrageenan, lambda carrageenan, xanthan gum, cold-water-soluble type of tamarind seed gum, tara gum, and psyllium seed gum; and
the second thickening agent is at least one selected from the group consisting of locust bean gum, heat-soluble type of iota carrageenan, native gellan gum, low-methoxyl pectin, and heat-soluble type of tamarind seed gum.

3. The method according to claim 1 , wherein the stock liquid further includes an additive.

4. The method according to claim 1 , wherein the stock liquid has a pH of 3.5 or more and less than 4.6.

5. The method according to claim 1 , wherein the dissolving the carbon dioxide gas in the stock liquid is performed cooling the stock liquid to a temperature of 5° C. or less.

6. The method according to claim 1 , wherein the heating is performed by heating the carbonated aqueous solution packed in the container for 1 to 40 minutes such that the carbonated aqueous solution has a temperature of 80 to 110° C.

7. The method according to claim 1 , wherein all liquids containing the second thickening agent are maintained at a temperature of less than 60° C., in all steps prior to the heating.

8. The method according to claim 1 , wherein all liquids containing the second thickening agent are maintained at a temperature of 0 or more and less than 60° C.

9. The method according to claim 1 , wherein all liquids containing the second thickening agent are maintained at a temperature of 0 to 35° C.
