Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention involves dissolving edible carbonate or edible acid and suspending metal foil surrounded by gel, and optionally also dissolving edible coloring whose color development is pH-dependent. The present invention relates to a beverage characterized by the above, and a kit containing such a beverage and an edible acid or an edible carbonate for generating carbon dioxide gas.

BACKGROUND OF THE INVENTION Beverages to which metal foil such as gold foil is added are already known.

[0003] However, in conventional beverages to which gold leaf, etc. have been added, the foil settles while it is left standing, and the foil does not move unless the container is moved strongly. I can't fully enjoy it.

0004

[Problems to be Solved by the Invention] An object of the present invention is to provide a beverage in which one can fully and easily enjoy the shine and movement of the metal foil added thereto, and in addition, one can also enjoy the change in color at the same time if desired. With the goal.

[0005]

[Means for Solving the Problems] As a result of extensive research, the present inventor has found that metal foil can be easily suspended in a beverage by incorporating it in gel, and that carbon dioxide gas can be generated at the bottom of the beverage to achieve this effect. It was discovered that the above-mentioned problem can be solved by giving movement to the metal foil and, if desired, dissolving food coloring whose color development is pH-dependent in the beverage.Based on these findings, the present invention was developed. completed.

That is, the present invention relates to a beverage characterized in that a metal foil in which an edible carbonate or an edible acid is dissolved and encapsulated in a gel is suspended.

The present invention will be explained in detail below.

[0008] The edible carbonate of the present invention may be any carbonate as long as it has been approved to be added to foods, and examples thereof include sodium bicarbonate, magnesium carbonate, calcium carbonate, potassium carbonate, and the like. Furthermore, any edible acid may be used as long as it is approved for addition to foods, and examples thereof include citric acid and L-tartaric acid.

[0009] Examples of the metal foil include edible materials such as gold foil. The gel that should contain the metal foil may be of any material that is approved for addition to foods and that does not turn into a sol when sterilized by heating, such as gellan gum, curdlan, konjac mannan, etc. Mention may be made of gels.

[0010] The metal foil surrounded by gel can be created by the usual method; for example, the metal foil is poured into a warm solution (sol) of gellan gum, stirred, and when it cools and solidifies (gelatizes), it is cut into small pieces. This can be done by

There are no particular limitations on the ingredients of the beverage of the present invention, other than edible carbonates or edible acids, as long as they do not interfere with the purpose of the present invention. Beverages in which edible acids are dissolved include, for example, so-called isotonic drinks and sports drinks, which are aqueous solutions of sugars (sugar, high-fructose liquid sugar), citric acid, its Na salt, inorganic salts, vitamins, and fragrances. I can list things that have been done. However, it is necessary to increase the amount of citric acid in these drinks by the amount necessary for the reaction with carbonate to generate carbon dioxide gas.

[0012] In order to make the metal foil encapsulated in gel float in the beverage, it is preferable that the specific gravity of the beverage and the specific gravity of the metal foil encapsulated in gel be the same or almost the same. A person skilled in the art can very easily do this with some preliminary experimentation. According to the findings of the present inventor, the specific gravity of such metal foils is almost all within the range of 1.02 to 1.06 g/mL, and most of the specific gravity is within the range of 1.03 to 1.05 g/mL. be. The specific gravity of the beverage can be adjusted to such a specific gravity range by adjusting the sugar content of the beverage. According to the inventor's findings, the specific gravity of the beverage is 1.02 to 1 with a sugar content of 5 to 20.
．． 06g/mL, sugar content 8-12, specific gravity 1.03
~1.05 g/mL.

Now, in order to enjoy the shine and movement of the metal foil in a beverage containing metal foil according to the present invention, it is sufficient to move the container lightly enough to move the beverage inside the container, but if carbon dioxide gas is generated at the bottom of the beverage, This enjoyment can be significantly improved. For this purpose, if the beverage contains dissolved edible carbonates, edible acid and if the edible acids are dissolved, edible carbonates are respectively supplied to the bottom of the beverage placed in the container. Such a supply of the edible acid or edible carbonate may include, for example, the edible acid or edible carbonate in the form of crystal grains or in the form of tablets, or when its specific gravity is lower than the specific gravity of the beverage, a specific gravity regulator, an excipient. This can be done by adding it to a drink in the form of a tablet made using a drug or the like. Since the introduced crystal grains or tablets have a specific gravity greater than the specific gravity of the beverage, they settle in the beverage and reach the bottom, where a reaction between acid and carbonate occurs to generate carbon dioxide gas.

[0014] The carbon dioxide gas rises in the beverage in the form of bubbles, and the bubbles create convection currents within the beverage, which causes the gel-encased metal foil suspended within the beverage to move around within the beverage. In this way, you can enjoy the shine and movement of the metal foil.

[0015] At this time, if a food coloring whose color development is pH-dependent is also dissolved in the beverage, the color change can be enjoyed at the same time.

[0016] Food dyes whose color development is pH-dependent can be added to foods that develop or change color while the pH of the aqueous solution changes from slightly acidic to neutral or from slightly alkaline to neutral. Any approved dye is fine,
Examples include anthocyanic and anthraquinone pigments.

The pH of the beverage changes from slightly acidic or slightly alkaline to neutral as a result of the convection within the beverage caused by the generation of carbon dioxide gas, and as a result, the color change gradually spreads throughout the beverage. In this way, you can enjoy not only the shine and movement of the metal foil, but also the change in color.

FIG. 1 illustrates the convection caused by the generation of carbon dioxide gas and the accompanying movement of the metal foil covered with gel in a beverage contained in a stemware.

The beverage according to the present invention is preferably stored in containers such as cans, bottles, PET bolts, hot packs, retort packs, etc. and sterilized before distribution for the purpose of preventing spoilage and facilitating handling. Moreover, these packaged beverages can be placed on the market in the form of a kit in combination with edible carbonate or edible acid crystals as they are or in the form of tablets. On the other hand, when used in the restaurant industry, etc., it is preferable to pour an aqueous solution into a glass as shown in Figure 1 and add crystals or tablets at the time of serving to customers.

[0020]

[Examples] The present invention will be further explained below with reference to Examples.

Example 1 First, 1.2 g of gellan gum was added to 1 L of water, and the
Dissolved in a water bath at °C. It was poured into a tray while it was hot, and immediately sprinkled with 0.05 g of gold leaf. After cooling and fixing the gold leaf, hot duran gum solution was again poured on top of it, and after it had cooled, it was cut into small pieces. The specific gravity of the gold leaf encapsulated in the gel thus prepared was 1.04 g/
It was mL.

On the other hand, add 10 liters of sodium hydrogen carbonate to 1 liter of water.
An aqueous solution was prepared by dissolving 100 g of liquid sugar and 23 μL of cochineal dye. The specific gravity of this aqueous solution is 1.04
g/mL.

[0023] 60 g of the gold foil encapsulated in the gel and 120 g of the aqueous solution were each taken out, packed into a 200 mL glass bottle, sealed tightly, and sterilized by retorting at an F value of 4. The pH at this time was 8.2.

[0024] 40 g and 100 g of the gold foil encapsulated in the gel thus prepared and the aqueous solution similarly prepared in this way were taken out, respectively, and poured into a 180 mL glass, and after stirring gently, the contents in the glass were dissolved. I left it until it stopped.

[0025] While the contents in the glass remained stationary, the gold foil encapsulated in the gel floated in the contents in the glass and was sparkling and beautiful.

[0026] In this state, 0.5 g of citric acid crystal grains were put into the glass. The citric acid crystal grains settled and carbon dioxide gas was generated inside the glass.

The generated carbon dioxide gas became bubbles and rose inside the glass, causing convection and at the same time, the gel containing the gold foil began to move while sparkling. At the same time, the pH gradually changed to the acidic side, so the blue drink gradually began to turn purple from the area where carbon dioxide gas was being generated, riding on the convection currents and eventually reaching the entire inside of the glass. The pH after the completion of the reaction was 4.2.

[0028] As a result of evaluating the thus obtained beverage, it was confirmed that it was refreshing and delicious.

[0029]

[Effects of the Invention] Beverages with the addition of metal foil to enjoy the shine and movement are known, but according to the present invention, it is easier to enjoy the shine and movement of the metal foil.

[0030] Furthermore, by adding and dissolving food coloring whose color development is pH-dependent in such beverages, it has become possible to enjoy the change in color.
