Description

  The present invention relates to a container-packed citric acid-rich acid beverage that is easy to drink and has high palatability, and a method for producing the same, even though it is an acidic beverage containing a high concentration of citric acid. .

  In modern society, even healthy people are said to feel “fatigue” on a daily basis, and various efforts have been proposed to recover from the fatigue. One of the simplest efforts is the intake of health food and drinks such as energy drinks. Many health foods and drinks containing various functional ingredients are on the market and are gaining popularity among consumers.

  Citric acid is known as one of the materials having the function of recovering from fatigue. Citric acid is an organic acid that is abundant in citrus fruits and is a substance used in many foods and drinks as an acidulant. This citric acid is a metabolic component in the TCA cycle and has been reported to be effective in fatigue recovery. In addition, citric acid is a material that has a very high utility value as a raw material for foods and drinks having an effect of relieving fatigue because citric acid is safe and has no problem even if it is ingested in a large amount for a long period of time. .

  For this reason, many attempts have been made to use this citric acid in foods and drinks and quasi drugs for recovery from fatigue. For example, Patent Document 1 discloses a liquid agent or tablet containing citric acid as a fatigue reducing agent containing an organic acid having two or more carboxyl groups or a salt thereof as an active ingredient. Patent Document 2 discloses an internal liquid preparation for physical fatigue, which contains a predetermined concentration of sucrose and citric acid. Further, Patent Document 3 discloses an internal solution for the purpose of fatigue recovery effect, in which one or more kinds of citric acid or a salt thereof at a predetermined concentration and royal jelly are blended.

  However, since citric acid is a sour agent in the first place, it has a strong acidity and has a peculiar taste, so if you increase the concentration of citric acid, the off-flavor from citric acid becomes conspicuous. It becomes a low and hard to drink beverage. In the above-mentioned Patent Document 2, the preference of the internal solution is raised by setting the mixing ratio of sucrose and citric acid, which are sweet substances, to a specific range, but it is premised on the manufacture of a small dose internal solution. Therefore, it is difficult to apply to general soft drinks. In addition, with respect to Patent Document 1 and Patent Document 3, since the importance of palatability is relatively low, and because it is based on the premise that it is a liquid preparation containing a plurality of functional materials having various tastes, There is no description of off-flavor problems such as excessive acidity derived from citric acid.

  On the other hand, in the field of general soft drinks where palatability is more important, when blending a large amount of citric acid to the extent that a functional effect can be expected, an off-flavor derived from citric acid that reduces palatability, especially Excessive acidity is regarded as a problem, and various proposals have been made for countermeasures. For example, in Patent Document 4, sodium succinate or sodium fumarate, and in Patent Document 5, sodium bicarbonate are mixed with citric acid in a specific amount, respectively, so that citric acid is contained in a high concentration. It is disclosed that the acidity derived from the citric acid can be alleviated. However, along with the influence on the beverage taste by the blended ingredients, the effect is not yet satisfactory, and further improvement is required.

  On the other hand, Patent Document 6 discloses a health drink comprising potassium citrate and a coffee-containing milk drink as constituent components. The health drink uses the health function of potassium, but the potassium citrate used has a unique bitter taste, and there is a problem that it is difficult to take with potassium citrate alone. By blending into a coffee-containing milk beverage, the bitterness is masked, making it a healthy beverage that is easy to consume.

Here, the citric acid-derived taste is a taste that is felt when drinking a beverage containing a high concentration of citric acid, such as excessive sourness and sashimi, and causes a decrease in the palatability of the beverage. .

<Citric acid>
Citric acid used in the present invention may be either citric acid anhydride or citric acid hydrate. As a source of citric acid, natural products such as fruit juices and fermented microorganisms containing abundant citric acid may be used, but food additive grade citric acid usually used as an acidulant is used. This is preferable because the quality is stable and the effect of the present invention becomes clear. Citric acid is 0.4 to 1.5% by weight, preferably 0.4 to 0.8% by weight, in the acidic beverage, including the portion derived from potassium citrate salt and sodium citrate salt. Adjusted to If citric acid is less than that, it will be necessary to ingest a large amount of beverage in order to fully demonstrate the anti-fatigue effect etc. of citric acid. Becomes too strong, and the effects of the present invention cannot be fully exerted, making it impossible to produce beverages with high palatability. It is adjusted to contain 2 to 7.5 g, preferably 2 to 5 g of citric acid per bottled beverage. The “citric acid concentration” in the citric acid-containing acidic beverage of the present invention is displayed by converting citric acid and citrate in the beverage into “citric acid”.

<Potassium citrate salt>
The present invention is characterized in that potassium citrate is added and contained in a high citric acid-containing acidic beverage. Potassium citrate has a unique bitterness, and when used in beverages, the bitterness of the beverage decreases due to its bitterness, but when used in acidic citrate-rich beverages Surprisingly, the citric acid sourness of the beverage not only makes the bitter taste of potassium citrate inconspicuous, but conversely, by showing the effect of reducing the taste of citric acid sourness, etc. It can be a high beverage.
