Description

  The present invention relates to a method of producing a carbonated beverage with a container.

  Dysphagia develops with encephalopathy such as stroke and Parkinson's disease, and muscle weakness due to aging. Dysphagia can cause the aspiration of food and drinks into the airway when swallowing food and drinks. Food and drink reaching the lungs may cause pneumonia. For this reason, thickeners have been added to beverages to impart a firmness, making them easy to drink and preventing errors.

  It is also possible to add thickener to carbonated beverages to impart consistency. However, carbonated beverages are more cumbersome to handle than ordinary beverages, are less likely to become thickened, and there is a problem that carbon dioxide gas is released during stirring in order to dissolve the thickener.

  Therefore, provision of carbonated beverages in which a thickened container is provided in advance and filled in a sealed container is desired.

  Generally, as a method of producing carbonated beverages, there is a method using an apparatus called a carbonator. In this method, a liquid is passed through a tank filled with carbon dioxide, and carbon dioxide is dissolved in the liquid to produce a carbonated beverage. When producing a thickened carbonated beverage by this method, a viscous liquid will be passed through a tank filled with carbon dioxide. However, carbon dioxide is difficult to dissolve in a viscous liquid, and the content of carbon dioxide becomes insufficient. In addition, when the liquid in which the dissolution of carbon dioxide is completed is filled into the container, there is a problem that the dissolved carbon dioxide is vaporized again due to the contact between the liquid and the inner surface of the container and the liquid overflows from the container. That is, carbon dioxide generated by the impact of contact between the liquid and the inner surface of the container rises to the upper portion of the container with the liquid having a thick, and overflows out of the container. For example, when a liquid containing carbon dioxide adjusted to gas volume 3 and having a viscosity of 10 mPa · s or more as measured by an E-type viscometer is to be filled in a container, spouting occurs and the viscosity is 50 mPa · s. It has been confirmed that the liquid which is the above causes more violent spillage. Spilling during filling leads to variations in the amount of liquid in the container. Therefore, it is difficult to industrially produce a thickened carbonated beverage by a method of incorporating carbon dioxide gas into a thickened liquid using a carbonator.

  As another method for producing carbonated beverages, there is a method in which an aqueous solution containing bicarbonate such as sodium hydrogen carbonate and an aqueous solution containing an acid such as citric acid or tartaric acid are mixed and reacted to generate carbon dioxide in the aqueous solution (Patent Document 1).

Japanese Patent Application Laid-Open No. 1-86862

However, in the method of Patent Document 1, the reaction rate between the salt and the acid is fast, and much of the generated carbon dioxide escapes from the aqueous solution. As a result, it is difficult to control the amount of carbon dioxide dissolved in the aqueous solution Have the problem of Furthermore, when a thickener is added to the carbonated water produced in this way in order to impart stiffness, there is a problem that carbon dioxide is released during stirring.
The problem to be solved by the present invention is to provide a method for stably producing a carbonated carbonated beverage which contains sufficient carbon dioxide.

  A method for producing a carbonated beverage with a container according to an embodiment includes filling a container with a first aqueous solution containing at least one of a carbonate and a bicarbonate and a second aqueous solution containing an acid that can be added to food. And, after the filling is complete, sealing the container. In this production method, at least one of the first aqueous solution and the second aqueous solution is provided with viscosity by containing a thickener component, and the inside of the container is mixed with the first aqueous solution and the second aqueous solution. Carbon dioxide is produced at

  In the container-packed carbonated carbonated beverage according to the embodiment, a carbonated beverage having a thickener component and having a viscosity of 10 mPa · s or more as measured by an E-type viscometer is sealed in a container.

  ADVANTAGE OF THE INVENTION According to this invention, it is suppressed that a carbon dioxide escapes, and the manufacturing method of the container packing and the carbonated carbonated beverage which can control the content in a container appropriately is provided.

  The manufacturing method of the carbonated beverage with a container packing and filthy which concerns on embodiment is demonstrated.

  Packaging and Fermented Carbonated Beverage is a carbonated beverage with a consistency that is filled and sealed in a container.

  By carbonated beverage is meant a beverage containing carbonic acid. Carbonated beverages generate carbon dioxide gas when consumed, thereby providing a refreshing sensation. In the method according to the embodiment, the amount of carbon dioxide dissolved in the beverage is not particularly limited and may be the same as the amount of carbon dioxide contained in a general carbonated beverage. The carbon dioxide gas volume is about 1 to 2 in a general carbonated beverage, and about 3 in a carbonated beverage containing higher carbonate such as cola. Here, the gas volume is the value of the amount (volume) of gas contained relative to the amount (volume) of the beverage at 20 ° C.

  Carbonated beverages have a firmness. By "solidity" is meant a viscosity that does not cause the liquid to lose its fluidity. In terms of not losing fluidity, the thickened carbonated beverage can be said to be in the form of sol rather than gel.

  The container can seal the liquid and can withstand the internal pressure of the carbonated beverage. In the method according to the embodiment, a container used for a general carbonated beverage can be used. Examples of containers are steel cans, aluminum cans, glass bottles and PET bottles.

  The manufacturing method according to the embodiment includes filling the container with the first aqueous solution and the second aqueous solution.

  The first aqueous solution contains at least one of a carbonate and a bicarbonate. Examples of carbonates are calcium carbonate, sodium carbonate and potassium carbonate. An example of a bicarbonate is sodium bicarbonate (sodium bicarbonate). The first aqueous solution may comprise these combinations of carbonate and bicarbonate in any combination. The total concentration (w / w) of carbonate and bicarbonate in the first aqueous solution is preferably in the range of 1% to 10%.

  The second aqueous solution contains an acid that can be added to the food. Examples of acids that can be added to food are citric acid, tartaric acid, lactic acid, malic acid, acetic acid, phytic acid and phosphoric acid. The acid concentration (w / w) of the second aqueous solution stream is preferably in the range of 1% to 70%.

  At least one of the first aqueous solution and the second aqueous solution further comprises a thickener component. Thereby, viscosity is imparted to at least one of the first aqueous solution and the second aqueous solution. The thickener component may be a thickener generally used for food. Examples of thickener components are xanthan gum and thickeners based on xanthan gum. Xanthan gum is a widely used ingredient to impart consistency. Examples of thickener components other than xanthan gum are guar gum, starch, tamarind gum, pectin and psyllium seed gum. Preferably, both the first aqueous solution and the second aqueous solution comprise a thickener. The addition amount of the thickener component in the first aqueous solution and the second aqueous solution can be set so that the viscosity of each aqueous solution becomes a predetermined value.

The viscosity of each of the first aqueous solution and the second aqueous solution to which the thickener is added may be 10 mPa · s or more. The upper limit of viscosity can be determined by the limit at which the solution can be filled. Generally, the limit of viscosity at which the solution can be filled is considered to be 500 mPa · s. Also, the upper limit of viscosity can be determined by the limit at which the solution can be mixed in the vessel. When the viscosity of the solution is too high, the solution becomes difficult to mix, the reaction speed is slow, and it takes too long to complete the reaction. The viscosity can be adjusted to avoid such problems.
In the present specification, the viscosity refers to the viscosity at a liquid temperature of 20 ° C.

  Preferably, the viscosity of each of the first aqueous solution and the second aqueous solution is in the range of 10 mPa · s to 200 mPa · s, more preferably in the range of 25 mPa · s to 200 mPa · s, and most preferably 50 mPa · s It is in the range of 200 mPa · s. The viscosities described in the present specification are all values measured by an E-type viscometer. The E-type viscometer is a kind of rotary viscometer, and is a viscometer that reads the resistance that a rotating body receives from a fluid from a rotational torque.

  The first aqueous solution and the second aqueous solution may each contain a sweetener, a flavor, fruit juice, vegetable juice and the like. Alternatively, sweeteners, flavors, fruit juices, vegetable juices and the like may be packaged separately from the first aqueous solution and the second aqueous solution in a container. Thereby, it is possible to produce a thickened carbonated beverage having a desired taste and flavor. Moreover, you may add solid substances, such as flesh, as needed.

When filling the container with the first aqueous solution and the second aqueous solution, the two aqueous solutions may be mixed in advance outside the container and then filled into the container. In this case, it is desirable to incompletely mix the two aqueous solutions. Alternatively, the two aqueous solutions may be separately filled in the container. In this case, the two aqueous solutions may be filled into the vessel in sequence, or the two aqueous solutions may be filled into the vessel simultaneously. Preferably, the two aqueous solutions are separately filled into the container without prior mixing outside the container.
The mixing ratio (mass) of the first aqueous solution and the second aqueous solution can be a mixing ratio suitable for generating carbon dioxide, and can be, for example, in the range of 1:10 to 10: 1.

  The manufacturing method according to the embodiment includes sealing after the filling is completed.

  Sealing can be performed by the general method of sealing a container for drinks. For example, when the container is a can, the contact portion between the can lid and the can barrel is wound and sealed. If the container is a plastic bottle, seal it by attaching a cap to the plastic bottle spout.

  The manufacturing method according to the embodiment may further include stirring the contents in the container. In particular, the stirring can take place after sealing the container.

  Agitation is preferably performed by applying an acceleration to the liquid and moving it in the container. Such stirring can be performed, for example, by shaking, rolling, or rotating the container. In particular, when the viscosity of the aqueous solution is high, it is preferable to stir and mix the liquid in the container.

  The manufacturing method according to the embodiment may further include cooling the sealed container.

  The cooling can be performed until the carbon dioxide gas generated in the container is completely dissolved in the aqueous solution. For example, the sealed container is kept at a low temperature for about 24 hours. The temperature of cooling may be maintained at a temperature at which the aqueous solution does not freeze and at a temperature lower than room temperature. For example, the temperature of cooling is 0 ° C to 10 ° C.

  The actions and effects of the manufacturing method according to the embodiment will be described below.

  In the manufacturing method according to the embodiment, carbon dioxide is generated in the container by mixing the first aqueous solution and the second aqueous solution. At this time, the reaction that generates carbon dioxide proceeds mildly because the consistency is imparted to at least one of the first aqueous solution and the second aqueous solution.

  If the aqueous solution has no or almost no stiffness, the two aqueous solutions are immediately mixed and the reaction proceeds rapidly. For example, if the viscosities of the two aqueous solutions are both less than 10 mPa · s, the reaction speed is increased and carbon dioxide is vigorously generated. In addition, when the viscosity is further lowered to 5 mPa · s or less, the generated carbon dioxide does not stay in the aqueous solution, and is immediately removed.

  On the other hand, when the aqueous solution has a certain viscosity, the two aqueous solutions are mixed slowly, the reaction speed becomes mild, carbon dioxide is generated little by little, and the generated carbon dioxide escapes from the aqueous solution Stay inside without. For this reason, after the container is filled with the first aqueous solution and the second aqueous solution, carbon dioxide hardly leaks out of the container until it is sealed, and the dissolved amount of carbon dioxide in the solution can be stabilized. .

  Furthermore, even when the first aqueous solution and the second aqueous solution are mixed in advance outside the container, the reaction proceeds gently due to the influence of the solidity, resulting in the contact between the aqueous solution and the inner surface of the container when filling the container Generation of carbon dioxide is suppressed. In addition, when the first aqueous solution and the second aqueous solution are separately charged into the container, the reaction between the aqueous solution and the inner surface of the container does not occur since the reaction that generates carbon dioxide originally does not occur when the aqueous solution contacts the inner surface of the container. There is no carbon dioxide emission caused. Therefore, the overflow of the aqueous solution to the outside of the container due to the rapid generation of carbon dioxide caused by the filling of the container can be suppressed. As a result, it is possible to suppress the variation in the amount of the aqueous solution filled in the container, and to produce containerized and carbonated carbonated beverages with stable quality.

  In addition, when both the first aqueous solution and the second aqueous solution contain a thickener, the density values of both aqueous solutions become close to each other, it becomes difficult to separate when mixed, and the reaction reliably proceeds, so that carbonated beverages It can be produced more efficiently.

  In addition, as described in “Experimental Example 2” of an example described later, a carbonated beverage to which solidity is imparted and which contains carbon dioxide of gas volume 3 is manufactured according to the conventional manufacturing method, and the container is used as a container. In the case of filling, when the viscosity is 10 mPa · s or more, spouting occurs at the time of filling, and when the viscosity is 50 mPa · s or more, violent spouting occurs. Therefore, the manufacturing method according to the embodiment is significant in the case of producing a carbonated beverage with a viscosity of 10 mPa · s or more and producing a carbonated beverage with a viscosity of 50 mPa · s or more. It is even more significant.

  A container-packed carbonated beverage according to an embodiment will be described.

  In this embodiment, the meanings of the words "bottled carbonated beverage with toromi," "carbonated beverage", "tormomi", "container" and "thickener component" refer to the carbonated beverage with containerate according to the embodiment. It has the same meaning as described above for the manufacturing method.

  In this embodiment, in particular, the carbonated beverage has a viscosity of 10 mPa · s or more as measured by an E-type viscometer.

  The container-packed carbonated carbonated beverage according to the embodiment may be one produced by the above-described method according to the embodiment.

Production Example 1
The packed and carbonated carbonated beverage was produced using the first aqueous solution and the second aqueous solution both containing a thickener as follows.

(Preparation of first aqueous solution)
In 120 g of water, 3.15 g of sodium hydrogen carbonate was dissolved, and further, 1.5 g of Sunsupport S-4 (manufactured by San-Ei Gen FFI) mainly containing xanthan gum as a thickener was dissolved. Thereafter, the mixture was diluted with water to a total of 145 g, and a sodium hydrogen carbonate viscous solution was prepared as a first aqueous solution.

(Preparation of second aqueous solution)
In 120 g of water, 10.5 g of granulated sugar and 3 g of citric acid were dissolved, and further, 1.5 g of Sunsupport S-4 (manufactured by San-Ei Gen FFI) was dissolved as a thickener. Thereafter, it was diluted with water to a total of 145 g, and a citric acid viscous solution was prepared as a second aqueous solution.

(Filling, sealing and cooling)
Into a container capable of containing 300 g of aqueous solution and sealable, 145 g of the prepared second aqueous solution was charged. Next, 145 g of the first aqueous solution was filled and sealed. The sealed container was shaken and mixed well. The viscous solution container was cooled and stored in a refrigerator at 10 ° C. for 24 hours to dissolve generated carbon dioxide.

  After cooling, the container was opened and a drinkable carbonated beverage was completed.

Production Example 2
A packed and carbonated carbonated beverage was produced using the first aqueous solution without thickener and the second aqueous solution with thickener as follows.

(Preparation of first aqueous solution)
In 120 g of water, 3.15 g of sodium hydrogen carbonate was dissolved, and diluted with water to a total of 145 g to prepare a sodium hydrogen carbonate solution as a first aqueous solution.

(Preparation of second aqueous solution)
In 120 g of water, 10.5 g of granulated sugar and 3 g of citric acid were dissolved, and 3.0 g of Sunsupport S-4 (manufactured by San-Ei Gen FFI) was further dissolved as a thickener. Thereafter, it was diluted with water to a total of 145 g, and a citric acid viscous solution was prepared as a second aqueous solution.

(Filling, sealing and cooling)
Into a container capable of containing 300 g of aqueous solution and sealable, 145 g of the prepared second aqueous solution was charged. Next, 145 g of the first aqueous solution was filled and sealed. The sealed container was shaken and mixed well. The viscous solution container was cooled and stored in a refrigerator at 10 ° C. for 24 hours to dissolve generated carbon dioxide.

  After cooling, the container was opened and a drinkable carbonated beverage was completed.

  When the above Production Examples 1 and 2 are compared, Production Example 1 has an advantage that mixing of the two aqueous solutions is easy because the densities of the two aqueous solutions are equal. On the other hand, Production Example 2 has the advantage that the work load of the step of producing the aqueous solution is small since the thickener only needs to be added to the first aqueous solution.

[Experimental Example 1]
The relationship between the viscosity of the two aqueous solutions and the degree of carbon dioxide evolved was investigated.

  Citric acid viscous solution containing 1.7% (w / w) citric acid and thickener (Sunsupport S-4 (manufactured by San-Ei Gen FFI)), and 2.2% (w / w) hydrogen carbonate Two solutions of sodium hydrogen carbonate viscous solution containing sodium and a thickener (Sunsupport S-4 (from San-Ei Gen FFI)) were prepared. At this time, the addition amount of thickener was adjusted, and eight solutions having different viscosities as described in the left column of Table 1 below were prepared for each of the two solutions.

100 g of each solution having the same viscosity was placed in a beaker, and the extent to which carbon dioxide was generated and the extent to which carbon dioxide escaped from the solution were visually confirmed. The results are summarized in Table 1.

From the above results, it can be seen that carbon dioxide is vigorously generated when the two solutions have viscosities of 5 mPa · s or less, and it quickly escapes from the solution. On the other hand, it can be seen that carbon dioxide is less likely to come out of the solution at 10 mPa · s, and the generation of carbon dioxide is further lowered at 25 mPa · s. Further, it can be seen that at 50 mPa · s or more, the generation of carbon dioxide is slight, and the generated carbon dioxide hardly escapes out of the solution.
Also, none of the eight solutions caused the aqueous solution to overflow out of the container due to the rapid generation of carbon dioxide resulting from the filling of the container.

[Experimental Example 2]
The relationship between the viscosity of the carbonated beverage and the degree of spouting when filling it into a container was examined. In this experiment, carbonated beverages were produced by conventional methods and filled into containers.

  A solution was prepared which was adjusted to gas volume 3 and to which a thickener was added. At this time, the amount of thickener was adjusted to prepare eight solutions with different viscosities as described in the left column of Table 2 below.

  The eight solutions were kept at 10 ° C., and each 290 g was filled into a 300 ml PET bottle-like container (a container whose mouth is recessed).

The degree of spouting during filling was visually confirmed. The results are summarized in Table 2.

  From the results in Table 2, it was found that when the viscosity was 5 mPa · s or less, no spilling occurred. On the other hand, in the case of 10 and 25 mPa · s, spouting occurred, and it was found that spouting occurred violently at 50 mPa · s or more.

  That is, it is understood that the conventional method is not suitable for handling carbonated beverages having a viscosity of 10 mPa · s or more.

  Therefore, the production method of the present invention is significant in the case of producing a carbonated beverage with a viscosity of 10 mPa · s or more, and is further significant in producing a carbonated beverage with a viscosity of 50 mPa · s or more. The significance is great.
