According to the invention shown in the 1 and 2, without requiring an excessive capital investment in facilities, can provide a carbonated beverage and a manufacturing how can exhibit blood glucose increase inhibitory effect.

  The effects of the present invention will be described in detail below.

Traditionally, sodium bicarbonate as citric acid and bicarbonate salt as an organic acid when dissolved in water, occurs violently neutralization reaction while dissolving, like blood glucose increase inhibitory effect of those bubbles of carbon dioxide gas is generated Not found at all.

  According to the study by the present inventor, it was found that this foamy carbon dioxide gas has a small amount dissolved in water, and the concentration of carbon dioxide gas in the dissolved water is extremely low.

  Therefore, the present inventor continued his research on the concentration of carbon dioxide.

  According to the research conducted by the present inventor, even if a citric acid and sodium hydrogencarbonate are caused to undergo a vigorous neutralization reaction with acid to generate carbon dioxide gas having a bubble diameter that is visible, most of the carbon dioxide gas is converted to water. It has the property of volatilizing out of the liquid without being dissolved.

  Therefore, the present inventor has focused on the pH value of the dissolved water and found that the control, that is, the mixing ratio of citric acid and sodium hydrogen carbonate is related.

Additionally, dissolved carbon dioxide concentration was also discovered that an important element in the blood glucose level increase suppression effect.

  In order to satisfy such a dissolved carbon dioxide concentration, the present inventor solves the problem of the present invention by further combining a dissolved water of citric acid and sodium hydrogen carbonate satisfying a specific mixing ratio with a carbon dioxide gas injection means. Was successful.

Hereinafter, the present invention will be described in detail.
As the carbonated beverage manufacturing apparatus used in the present invention, known apparatuses can be used without any special limitation.
For example, an efficient manufacturing apparatus for bathing or drinking carbonated spring described in JP-A-2013-212450 can be mentioned.

That is, a device in which a tank containing an acidic solution and a tank containing an alkaline solution are arranged adjacent to each other on the upper surface of a base having a float attached to the lower surface,
A tank containing an acidic solution is used by adding an acidic solution prepared by mixing and stirring a predetermined amount of citric acid in a predetermined amount of water, and a tank containing an alkaline solution is used in a predetermined amount of water. Mix and stir the baking soda and add the dissolved alkaline solution.

  The shape of the tank that holds the acidic solution and the shape of the tank that holds the alkaline solution is a half-cone trapezoid, and when the parts that are vertical flat surfaces are set back-to-back, the shape becomes a truncated cone. The tank containing the pair of acidic solution and the tank containing the alkaline solution set on the base are swiveled and used while being floated above the hot water surface in the bath by the float ring on the bottom of the base.

  Mixing ratio of each citric acid to a given amount of water and sodium bicarbonate (sodium hydrogen carbonate) so that the pH of carbonated spring obtained by contact mixing of acidic solution and alkaline solution is from weakly acidic to strongly alkaline Since each bag pack of an acidic solution and an alkaline solution having a predetermined concentration suitable for each is prepared in advance by adjusting the mixing ratio of, the bag pack of the acidic solution suitable for carbonated water of a desired pH among them is prepared. The bag pack of the alkaline solution and the alkaline solution is selected, and the acidic solution and the alkaline solution contained in each pack are put into the acidic solution storage tank and the alkaline solution storage tank, respectively.

  The pair of acidic solution storage tank and alkaline solution storage tank is a carbon dioxide gas generation unit with a spherical inner and outer tank integrally molded through a protective pipe attached to the bottom surface of the base. It is vertically connected to the tank.

  The tank for storing the acidic solution on the base, the tank for storing the alkaline solution and the inner tank of the spherical carbon dioxide gas generation tank with the inner and outer double structure below it are the flow rate adjusting valves arranged in the protection pipe. Is connected via an acidic solution delivery pipe and an alkaline solution delivery pipe extending downwards, and the tip ends of the pair of acidic solution delivery pipe and alkaline solution delivery pipe are inside tanks of the carbon dioxide gas generation tank. It is arranged in a bent, facing, and facing position near the bottom wall inside.

  A plurality of small holes for discharging carbon dioxide are formed on the upper wall surface of the inner tank, and a mesh or brush-like mat is stretched around the inside of the tank.

  In this example, an air delivery pipe is extended and inserted into the inner tank of the carbon dioxide gas generation tank so that air is fed from the upper outside.

  Further, in the outer tank of the carbon dioxide gas generation tank, a plurality of small holes for outflow of carbonated water are formed in the lower wall surface, and water or hot water flow is sent to the inside of the tank from the outside above. Alternatively, a hot water delivery pipe extends and is inserted and arranged, and a large number of resin small balls are arranged.

The acidic solution and the alkaline solution in the acidic solution storage tank and the alkaline solution storage tank are carbon dioxide gas in a narrowly closed space with a relatively small volume through the flow rate control valve, the acidic solution delivery pipe, and the alkaline solution delivery pipe. The carbon dioxide gas is mixed by being carried deep inside the tank inside the generation tank, that is, to a position facing the lower surface wall, discharged from the tip of each delivery pipe that is bent and opposed to each other and directly touched, and mixed. To do.
The carbon dioxide gas and the water or warm water generated are mixed and stirred by the air that is pressure-fed from above into the inner tank through the air delivery pipe, and rise up, and the fibers are entangled in the mesh or brush-like mat disposed in the inner tank. It is pushed into the inside, passes through it, is sent upward along the spherical or cylindrical tank inner wall surface, and is discharged into the outer tank through the plurality of small holes formed in the upper wall surface.
Water or hot water is continuously fed into the outer tank from the outside through a water or hot water delivery pipe whose tip is bent along the inner circumferential surface of the tank and which is arranged upward. Therefore, carbon dioxide gas and water or hot water discharged into the same tank are pushed toward the lower wall surface along the inner peripheral surface of the outer tank by the incoming water flow, and are spread in the outer tank at that time. A large number of small resin balls are mixed and agitated when passing through the small balls, and are guided to a plurality of small holes formed in the lower wall surface.
Therefore, the generated carbon dioxide gas is sufficiently brought into contact with water to be mixed and stirred by the time it is guided to the plurality of small holes on the lower surface of the outer tank, so that the carbon dioxide gas is sufficiently absorbed and dissolved in the water and the concentration thereof is extremely high. It becomes expensive and the carbon dioxide gas foam becomes ultrafine.
Further, the foaming effect can be maintained for a considerably long time as compared with the conventional one.

  In the case where a float ring is attached to the bottom surface of this base, the device can be used by floating it in a bathtub, so the device can also be used by rotating it in a bath. The carbon dioxide gas generated in the carbon dioxide gas generation tank in a closed space with a small volume can be more smoothly contact-stirred with the water or hot water staying in the tank. It can further contribute to enhancement of the dissolved concentration of carbon dioxide gas.

  The pH of the carbonated spring obtained by contact-mixing an acidic solution and an alkaline solution can be easily adjusted by changing the mixing ratio of each citric acid and sodium bicarbonate (sodium hydrogen carbonate) to a predetermined amount of water or warm water. it can.

It is possible to make it suitable for drinking by using edible additive grade sodium bicarbonate (sodium hydrogen carbonate) that is mixed and dissolved in the storage tank for acidic solution and mixed and stored in the storage tank for alkaline solution. ..
Note that sodium carbonate may be used together with sodium bicarbonate (sodium hydrogen carbonate).

  Next, for the carbon dioxide gas injection in the present invention, for example, known carbon dioxide gas injection techniques described in JP-A-10-136953, JP-A-2010-142129, JP-A-2013-11, etc. are adopted without any special limitation. it can. In that case, as described in JP-A-2010-142129 (see particularly [0025] and [0026]), the aseptic filling method and the filling device can be used.

The pH of the carbonated beverage according to the present invention before the carbon dioxide gas is injected is preferably 4.0 to 9.3, particularly 6.0 to 9.0, and the pH after the carbon dioxide gas injection is 5 0 to 8.7 is preferable, and examples of the pH adjuster include dipotassium phosphate, disodium phosphate, trisodium phosphate, tripotassium phosphate, sodium citrate, sodium lactate, sodium gluconate, potassium gluconate, It can be carried out by adding one or more alkaline pH adjusting agents consisting of disodium succinate, sodium malate, sodium tartrate, sodium carbonate, sodium glutamate, calcium lactate, and calcium gluconate. In addition, if necessary, the pH of the carbonated beverage raw material liquid is adjusted by adjusting one or more of acidic pH adjusting agents such as phosphoric acid, lactic acid, malic acid, tartaric acid, acetic acid, fumaric acid, phytic acid, and vitamin C. It can be performed by adding.
The citric acid-containing carbonated beverage according to the present invention may contain a sodium component or the like.

The carbonated beverage according to the present invention has a citric acid: baking soda ratio of 1:2 to 7 (mass ratio) .

  When the ratio of baking soda is less than 2, the citric acid and sodium hydrogencarbonate undergo a vigorous neutralization reaction to generate carbon dioxide gas having a bubble diameter that is visible, and most of the carbon dioxide gas dissolves in water. However, when the ratio of baking soda exceeds 7, the solubility of the generated carbon dioxide gas in water decreases.

In the present invention, carbon dioxide gas is pressed into the dissolved water containing citric acid:sodium bicarbonate in a ratio of 1:2 to 7 (mass ratio) in water. Carbonated water this is pressed is 1,000~10,000ppm concentration, in the press-fitting amount of less than 1,000 ppm, the total concentration of carbon dioxide dissolved in the carbonated beverage water is insufficient to produce a blood glucose increase inhibitory effect There is a problem that is, on the other hand, when the amount of press fitting is more than 10,000 ppm, there is a disadvantage of reducing the blood sugar level rise suppressing effect reversed.

  There is no particular limitation on the concentration of citric acid in the carbonated beverage according to the present invention, but when 0.3 to 0.9 g of citric acid is contained in 1,000 g of the carbonated beverage, the effect of suppressing an increase in blood glucose level appears remarkably.

A carbonated beverage according to the present invention checks to that blood glucose increase inhibitory effect exerted, it is most preferable to measure changes in glucose levels in the blood, as an experimental example, [0070] of the Patent Documents 4 to [0080], reference may be made to FIGS. For example, before meals, immediately after finishing the meal while drinking the carbonated drink of the present invention, the change in the amount of blood glucose in the blood measured by collecting blood every fixed time, and eating while drinking a beverage other than the present invention The effect of the carbonated drink of the present invention can be confirmed by comparing the change in the blood glucose level in the blood with time.

Hereinafter, the present invention will be described in detail with reference to experimental examples showing the effects of the present invention, but the embodiment of the present invention is not limited thereto.
[Example]
Pure water was added to the edible additive grade citric acid Xg in a container and dissolved while stirring to finally prepare an acidic solution A of 500 g. Next, pure water was added to and dissolved in edible additive grade sodium bicarbonate Yg placed in another container with stirring to finally prepare an alkaline solution B of 500 g.
The acidic solution A and the alkaline solution B were mixed using the efficient manufacturing apparatus for drinking carbonated spring described in Example 1 (FIGS. 3 and 4) of JP-A-2013-212450, and then JP-A-2013-000011. Using the well-known carbon dioxide gas injection technique using the ace boutique filling method and the filling device described in No. 6, carbon dioxide gas was injected by Zppm, and 150 g each was bottled to make a total of 6 carbonated beverages of 6 bottles each.

Ingredients of 9 kinds of carbonated drinks Table 1 below shows the amount of citric acid Xg, the amount of sodium bicarbonate Yg, and the amount of carbon dioxide gas Zppm contained in 1,000 g of the 9 kinds of carbonated drinks.

Test content Next, a total of five healthy male and female subjects aged 25 to 60 were asked to ingest a small amount of white rice containing 50.0 g of sugar at 9 am after an overnight fast, and then drink carbonated drink 1 freely. I had them eat and drink everything within 10 minutes. Blood was collected from each test subject immediately after the completion of eating, drinking, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 90 minutes, and 120 minutes after the end, 7 times in total, 7 mL each. The blood glucose level (mg/dL) of the collected blood was measured by the hexokinase method using a biochemical analyzer AU480 (manufactured by Beckman Coulter, Inc.).
One week later, the same test was conducted on the same five male and female subjects, but a placebo beverage containing only 2,000 ppm of carbon dioxide gas was used instead of the bicarbonate beverage 1, and different healthy subjects 25 to 60 years old. A similar clinical study using carbonated drinks 2 to 9 was conducted on a total of 5 male and female subjects aged 20 years.

Nine different test results for a total of 5 different male and female subjects When the blood sugar level in the blood immediately after a meal was set to 0, the subjects with each carbonated drink and the placebo drink 5 The transition of the average blood sugar level in the blood of each name is summarized in Table 2 below.

From the above results, citric acid: sodium bicarbonate 1: contains a ratio of 2 to 7 (mass ratio), and 1,000~10,000ppm concentration carbonated beverage carbon dioxide gas was pressed in is the effect of the present invention, the blood It can be seen that it produces an effect of suppressing sugar level rise.
In this example, the amount of citric acid in 1,000 g of carbonated drinking water was limited to a fixed amount of 0.6 g, but citric acid: baking soda was 1:4, carbon dioxide gas injection amount was 2,000 ppm, and carbonated drinking water was 1,000 g. In a similar test in which the amount of citric acid in the solution was changed to 0.2 to 1.0 g, especially when the amount of citric acid in 1,000 g of the carbonated beverage was 0.3 to 0.9 g, the blood sugar level elevation suppressing effect was remarkably exhibited. confirmed.
