Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a discolorable powdered beverage that is dissolved in a liquid and served for drinking.

[Conventional technology]

A powdered beverage is generally a mixture of a sweetener such as powdered sugar, a dry powder of fruit juice, an organic acid such as citric acid, a coloring agent and a flavor, and dissolves a desired amount thereof in water when necessary for drinking. It has practical significance that it is convenient for storage and carrying.

However, since powdered beverages are dissolved in a liquid such as water, the dissolving process is monotonous, and therefore, the powdered beverage does not have an interesting appearance. In addition, since it is difficult to visually confirm that the dissolution has been completed, there is also a drawback that the dissolution residue is often used for drinking with the dissolution residue present, and discomfort is felt when drinking.

In view of the above-mentioned drawbacks of powdered beverages, discolorable powdered beverages containing soluble particles containing a solid organic acid therein, a basic substance, and an edible pigment that changes color due to liquidity have been devised. JP-A-63-148963).

When the discolorable powdered beverage is dissolved in a liquid, the liquidity of the solution exhibits a weak alkalinity due to the basic substance in the early stage of the dissolution process, and thereafter, as the dissolving of the soluble particles progresses, the inside of the discolored powdered beverage becomes weaker. By gradually dissolving the solid organic acid, the liquidity gradually shifts to the acidic side and finally exhibits a weak acidity.By incorporating a pigment that changes color according to this change in liquidity In addition, it is possible to enjoy the color change of the solution when drinking. At that time, the discoloration point of the dye is adjusted to the liquid property at the time of complete dissolution of all components, so that the discoloration time of the solution can be used as an indicator that the solution has reached the point of drinking.

[Problems to be solved by the invention]

In the discolorable powdered beverage described above, by providing a coating layer around the solid organic acid particles to make the soluble particles, the dissolution rate of the organic acid is slower than the dissolution rate of the basic substance. In order to control the color change, the dissolution rate of the soluble particles must be constant.

However, the solid organic acid particles have a polyhedral shape such as a rectangular parallelepiped or cubic, so even if a coating layer is formed around the particles using a granulator, the thickness of the coating layer becomes uneven. The dissolution rate of the obtained soluble particles varies easily. In other words, when trying to obtain soluble particles having a uniform thickness of the coating layer using the current granulation technology, a complicated manufacturing process and an expensive granulation device are required, and the manufacturing cost of the powdered beverage increases significantly. There is a problem of doing it.

The present invention has been made in view of the above-mentioned problems, and its object is to provide a discolorable powder that can enjoy a change in the color of a liquid during drinking and can eliminate discomfort due to powder residue. It is to provide a beverage at a low cost.

[Means for solving the problem]

In the present invention, the discoloration is caused by the liquid property of 90% by weight or more of a soluble organic acid particle having a particle size range of 12 to 32 mesh and 85% by weight or more of a soluble basic fine powder having a particle size of 250 mesh pass. It is a discolorable powdered beverage containing a pigment in such a proportion that the solution exhibits a weak acidity when all the components are dissolved in the liquid.

[Action]

In the present invention, the basic substance is dissolved in the liquid more quickly than the organic acid by making the particle size of the organic acid particles larger than the particle size of the chlorinated fine powder. This eliminates the need for a granulation step of forming a uniform coating layer, thereby reducing the production cost of the discolorable powdered beverage.

When the discolorable powdered beverage according to the present invention is dissolved in a liquid such as water, in the early stage of the dissolving process, the dissolution of the basic fine powder composed of particles smaller than the organic acid particles proceeds rapidly, and the liquid property of the solution is increased. Exhibits weak alkalinity. The solution maintains the alkalinity for a while due to the buffering action between the basic fine powder that dissolves quickly and the organic acid particles that dissolve gradually, but during this time, the dye dissolved in the solution develops color due to weak alkalinity. Present, with little change in color.

Thereafter, as the dissolution of the organic acid particles progresses, the liquidity of the solution gradually shifts to the acidic side, and finally reaches a weak acidity, but due to the buffering action, the shift to the acidic side is also slow. It is. However, when a dye having an appropriate discoloration range is selected, a slight change in liquid property causes rapid discoloration, and thus such a clear change in solution color gives the viewer pleasure and enjoyment.

In addition, by selecting a pigment that discolors in a liquid state when all the components constituting the powdered beverage are completely dissolved, the discoloration time of the solution can be used as an indication that the solution has reached the time of drinking, Discomfort at the time of drinking due to the remaining residue can also be completely eliminated.

Soluble organic acids contained in the discolorable powder beverage according to the present invention include citric acid, tartaric acid, malic acid, fumaric acid,
Edible solid organic acids such as malonic acid, succinic acid, and ascorbic acid can be exemplified. In some cases, two or more of these organic acids may be selected and mixed to appropriately adjust the taste of the powdered beverage.

The soluble organic acid exemplified above is at least 90% by weight thereof.
It is essential that the above is in the particle size range of 12 to 32 mesh. In other words, if the particle size is coarser than 12 mesh, the dissolution rate of the organic acid will be too slow and the discoloration of the solution will take a long time, which will distract the drinkers who want to enjoy the color change. I will. Further, since the organic acid particles remain in the solution even after the discoloration, it gives the drinker discomfort. On the other hand, if an organic acid having a grain boundary smaller than 32 mesh is used, the dissolution rate becomes too high and the discoloration of the solution is completed instantaneously, so that the drinker cannot be provided with sufficient playability.

Also, if the dissolution rate of the organic acid is too fast, the organic acid particles will be used for drinking while remaining in the solution,
It gives the drinker discomfort. Further, when the content of the soluble organic acid in the particle size range of 12 to 32 mesh is 90% by weight or less, the lower layer of the liquid exhibits an acidic color immediately after the powdered beverage is poured into the liquid, and the upper layer of the liquid Since the color differs between the lower layer and the lower layer, it gives a discomfort to the drinker.

Next, as a soluble basic substance, sodium carbonate,
Examples thereof include sodium hydrogen carbonate, calcium hydroxide, and calcined volley powder, and particularly preferred is calcined volley powder.

It is essential that at least 85% by weight or more of the soluble basic substance used in the present invention is a fine powder having a particle size of 250 mesh pass. When the amount is less than 85% by weight, the dissolution rate is slowed down, so that the powdered beverage is turned into a liquid as in the case where the content of the soluble organic acid in the particle size range of 12 to 32 mesh becomes 90% by weight or less. Immediately after being charged, the lower layer of the liquid exhibits the color of the acidic state, and the color of the upper layer differs from that of the lower layer of the liquid. If the dissolution rate of the basic substance is too slow, the basic substance may be combined with the pigment particles to form an aggregate, which may make it difficult to dissolve in the liquid.

Next, as a pigment that changes color due to liquidity, the pH range is 2 to 2.
Food dyes having a discoloration point in the range of weakly acidic to weakly alkaline of about 8 are preferred, and specific examples include Red No. 104, cochineal dye, lac dye, corn dye, red cabbage dye, grape juice dye and the like. be able to. In addition, the change of the color of these pigment | dye by the difference of a liquid property is shown in the following Table 1 (the parenthesis in the column of the pigment | dye name is a product name made from Sanei Chemical Industry Co., Ltd. in the table).

The discolorable powder beverage according to the present invention comprises the above-mentioned soluble organic acid particles, a soluble basic fine powder, and a basic component consisting of a pigment that discolors due to liquidity, fruit juice powder, pulp powder, and saccharides (sucrose, glucose, In addition to sweeteners such as fructose and maltose) and synthetic sweeteners, it is optional to add a flavoring agent, a colorant that does not change color due to liquidity, a flavor, a foaming agent, and the like. It is also optional to add and mix a commonly used food additive as an accessory component.

To produce the discolorable powdered beverage according to the present invention, the powders of the various components described above are mixed and stirred at such a rate that the solution exhibits a weak acidity when all the components are dissolved in the liquid, and then a predetermined amount thereof is added. , The production cost is extremely low.

In addition, in this discolorable powder beverage, since the organic acid particles and the basic fine powder are mixed, during storage, it is expected that both will react with time, but the dry powder is sealed and packaged. In this case, no change was observed for one year in a storage test at a humidity of 75% and a temperature of 40 ° C.
