Description

  The technology of the present invention relates to a packaged turmeric beverage containing a turmeric extract.

Turmeric ( Curcuma longa LINEN) is a medicinal plant belonging to the genus Turmeric belonging to the genus Turmeric that is cultivated in tropical and subtropical regions around the world, mainly in Southeast Asia.

  Turmeric rhizomes contain 3-5% curcumin (yellow pigment). Various utilities are known for turmeric extract and curcumin. For example, Non-Patent Document 1 suggests that a turmeric extract-containing beverage has an action of preventing sickness while appropriately expressing the “sickness” inherent in alcohol by ingesting together with alcohol.

  Focusing on the usefulness of turmeric, beverages containing turmeric pigments have been developed. Since turmeric pigments are sparingly soluble in water, various techniques for dispersing in water have been proposed.

  JP-A-2009-263638 discloses a turmeric pigment composition containing gati gum and a turmeric pigment having an average particle diameter of 1 μm or less in order to increase the dispersibility of turmeric pigment in water and the absorbability in the body. Has been. It is disclosed that this turmeric pigment composition is blended to blend a beverage composition having a turmeric pigment (curcumin) content of 0.3% by mass (1500 mg / 500 ml).

  JP-A 2008-92806 discloses that when turmeric powder is blended into a beverage, the turmeric powder is floated or agglomerated so as to solve the problem that it is not uniformly dispersed. A method for producing a turmeric-containing beverage to be dispersed is disclosed. As the turmeric powder, 0.2 μm to 260 μm is used. The amount of curcumin in the beverage prepared in the examples is about 200 mg per 500 ml.

  JP 2001-206844 discloses various curcumin formulations for improving the color stability, bioavailability, redispersibility, etc. of curcumin. It is also described that curcumin formulations can be used in the production of beverages.

  Comparative product 4 disclosed in Japanese Patent Application Laid-Open No. 2009-247283 is a dispersion in which turmeric powder pulverized to an average particle size of 22 μm or less is dispersed. The dispersion of Comparative Example 4 is estimated to contain about 1250 mg of curcumin per 500 ml. According to the document, this dispersion is not preferable in terms of redispersibility and color tone.

  In order to reduce thirst by quick hydration, the inventors predict that there is a demand for turmeric beverages that are easy to drink and can be consumed in relatively large quantities. Conventional turmeric beverages are generally marketed as container-packed beverages having a high concentration of turmeric extract and a relatively small volume in order to obtain the effect of turmeric extract, and are difficult to drink in large quantities. It was not enough to meet the demand.

  Such a beverage is usually marketed in a form packed in a container (typically, a transparent container made of PET (polyethylene terephthalate) or the like).

  Since curcumin, which is a turmeric pigment, is insoluble in water, there is a problem that turmeric pigment powder and other water-insoluble components of the turmeric extract are likely to precipitate in the container. When a transparent container is used as the container, deterioration of the appearance due to the occurrence of precipitation is a particular problem.

  JP-A-2009-263638 discloses that precipitation of turmeric pigments can be suppressed by using a refined turmeric pigment. However, the present inventors have confirmed that it is difficult to suppress the occurrence of precipitation only by dispersing the fine turmeric pigment in water.

  An object of this invention is to provide the container-packed turmeric drink by which precipitation of particulate turmeric pigment | dye etc. was suppressed.

  As a result of intensive studies, the present inventors have found that in a packaged turmeric beverage containing fine turmeric pigments and the like, by mixing divalent metal ions and setting the pH to 3.2 or more, precipitation of fine turmeric pigments and the like can be prevented. The inventors have found that generation can be suppressed and completed the present invention.

The present invention includes the following inventions.
(1) A container-packed turmeric beverage comprising a turmeric beverage containing a turmeric extract and a container for containing the beverage,
(A) The turmeric extract contains a micronized turmeric extract,
(B) The turmeric extract contains a divalent metal ion,
(C) The pH of the turmeric drink is 3.2 or more,
A packaged turmeric drink characterized by that.
(2) The container turmeric beverage according to (1), wherein the container is a transparent container.
(3) The container-packed turmeric beverage according to (1) or (2), wherein the micronized turmeric extract is a particulate turmeric pigment.
(4) The container-filled turmeric beverage according to any one of (1) to (3), which contains 0.005% by mass or more of a divalent metal ion.
(5) The packaged turmeric beverage according to any one of (1) to (4), wherein the divalent metal ions are calcium ions and / or magnesium ions.

  The container turmeric drink of the present invention is a container-filled turmeric drink that is drunk to reduce thirst by quick hydration and in which the precipitation of turmeric pigment powder is suppressed.

FIG. 1: shows the longitudinal cross-sectional view of an example of embodiment of the container turmeric drink of this invention. FIG. 2 shows a perspective view of the appearance of an example of an embodiment of the packaged turmeric beverage of the present invention.
