Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extract characterized by containing taurine. More specifically, at least one selected from the group consisting of tea leaves, coffee beans, soup stock and crude drugs is used in the presence of taurine. And a taurine-containing extract obtained by extraction.

[0002]

2. Description of the Related Art Tap water is usually used to extract useful / active ingredients, umami components, etc. contained in tea leaves, coffee beans, soup stocks and crude drugs, but is conventionally contained in tap water. Various adverse effects such as deterioration of taste due to residual chlorine have become a problem. In particular, in recent years, the water quality of rivers has been increasingly deteriorating. The causes include an increase in domestic wastewater and industrial wastewater, deforestation due to development, and the like. In such tap water from polluted rivers, the amount of chlorine mixed in for disinfection must be increased, and the hardness of tap water also increases, and as a result, tap water has become synonymous with "bad water" .

[0003] In order to remove the chlorine odor (so-called odor of lime) from tap water, conventional methods such as pumping and boiling are available.
In the former case, there is concern about the propagation of various bacteria in the summer, and it is not expected to reduce the hardness of water. On the other hand, the latter requires time and effort such as heating and cooling. In recent years, tap water containing chlorine has been highly treated with ozone or activated carbon, and bottled mineral water that has no chlorine odor and low hardness has been used recently. In some cases, there are some problems, such as the occasional regeneration and replacement of activated carbon, and labor such as water sampling and transportation in mineral water, and it is frequently used in individual homes or restaurants, or used outdoors. Is currently a problem.

[0004]

SUMMARY OF THE INVENTION The present invention requires special equipment for extracting tea leaves, coffee beans, soup stock and crude drugs with tap water containing residual chlorine and having relatively high hardness. In addition, an object of the present invention is to provide an extract in which deterioration of taste and the like is suppressed by a simple and economical method. The present inventors have conducted intensive studies in view of the above-described problems, and as a result, surprisingly, in the presence of taurine when extracting with tap water, that is, by using taurine, deterioration of the taste etc. of the extract The present invention has been completed based on the finding that can be significantly suppressed. It is another object of the present invention to efficiently absorb taurine having various medicinal effects and useful for the human body into the body.

[0006]

DETAILED DESCRIPTION OF THE INVENTION (1) Taurine Taurine, ie, aminoethanesulfonic acid (H ₂ NCH ₂ CH)
₂ SO ₃ H) is a sulfur-containing amino acid that is widely distributed in the animal and plant kingdoms, but is particularly present in large amounts in bovine bile and in squid, octopus, and shellfish extracts. Taurine has a stimulating effect on human cells and a tonic effect on various organs such as myocardium, gall bladder and liver, and has an excellent effect on cosmetics and prevention of hangover. It is known to exert Taurine is also said to have an effect of preventing arteriosclerosis because it enhances digestion and absorption of fats and fatty vitamins, suppresses bad cholesterol, and promotes bile secretion.

The present invention has, in addition to the above-mentioned known effects, an excellent water quality improving effect of taurine, that is, an effect of suppressing chlorine odor and reducing hardness of tap water. It has been achieved based on new knowledge that can be provided. Although the mechanism of such taurine water quality improvement is not clear, taurine is chemically one of amino acids.
Due to its species, it has anionic and amphoteric properties. These properties of taurine act on trace substances in tap water and exert the effect of improving water quality as described above, that is, the effect of suppressing the deterioration of taste caused by chlorine even when using tap water containing chlorine. It is supposed to do.

[0008] Taurine itself is a tasteless and odorless substance.
Therefore, even if it is contained in the extract of tea leaves, coffee beans, soup stock and crude drug, it does not affect the taste and smell originally possessed by them. Of course, since taurine is contained in the extract, it goes without saying that various pharmacological effects due to ingestion of taurine into the human body can be expected at the same time as suppressing taste deterioration.

Further, in the present invention, it has been revealed that taurine is efficiently absorbed into the body by taking it together with the extract of tea leaves, coffee beans, soup stock and crude drug. This is presumed to be due to the fact that the extract stimulates the digestive tract to increase blood flow on the surface of the digestive tract, thereby increasing the absorption of taurine in the body. Taurine in the present invention can be used by appropriately purchasing a commercially available product, but may be a natural product or a synthetic product.

When the amount of taurine to be used is an extraction treatment with an aqueous solution of taurine, the amount of taurine in the aqueous solution is not more than 0.1.
It is preferably from 01 to 8% by weight, particularly preferably from 0.1 to 1% by weight. In addition, in the case of a mixture comprising powdered taurine, the amount of powdered taurine is 0.1% based on the amount of water used for extraction.
It is preferably from 01 to 8% by weight, particularly preferably from 0.1 to 1% by weight. However, such a quantitative range is based on the case where the water used for extraction is based on room temperature (20 ° C.) tap water having a residual chlorine of 0.2 to 10 mg / L. It is not limiting as the solubility of taurine also increases.

(2) Extraction processing The objects of the extraction processing in the present invention are tea leaves, coffee beans, soup stock, and crude drugs. Examples of the tea leaves include unfermented tea such as green tea, fermented tea such as black tea and oolong tea, and barley tea. Regardless of their origin and brand, two or more kinds may be blended. The coffee beans may be in any place of origin or brand, and may be a blend of two or more. Dashi ingredients include natural foods containing umami ingredients such as bonito, boiled dried fish, kelp, shiitake mushrooms, scallops, etc. used in Japanese cuisine, and beast birds used in soups of Western and Chinese cuisine, such as beef, pork and chicken meat. Examples include bones, seafood, flavored vegetables, and the like.

[0012] Crude drugs are obtained by subjecting naturally occurring materials such as plants, animals, minerals and the like to simple treatment such as drying so that they can be used for medicinal purposes. In plants, whole plants, roots, stems, leaves, flowers, etc. ,
Fruits, seeds, bark, whole animals, organs, horns, shells,
There are skin and secretions. The crude drug of the present invention is intended for so-called health foods and health teas, and examples of health teas include turmeric tea, ginseng tea, persimmon leaf tea and mugwort tea. These crude drugs can be blended in two or more kinds. The health tea may be a blend with the above-mentioned tea leaves (green tea, black tea, oolong tea, barley tea, etc.). Among the objects of the above-mentioned extraction processing, tea leaves (especially green tea), coffee, and healthy tea (turmeric) can be obtained by taking these extracts containing taurine rather than taking taurine with water. It is preferable because it has an effect of increasing the absorption amount.

In the present invention, the object to be extracted is subjected to an extraction treatment in the presence of taurine. A method of extracting the object with an aqueous solution of taurine, a method of extracting a mixture of the object and powdered taurine with water, There is a way to do that. In the former method, a separate treatment for separating the extract from the solid matter of the extraction residue is required. On the other hand, in the latter method, the mixture is
Packing in a container in which water permeates but retains the solids, such as a tea bag, eliminates the need for separation treatment of the solids residues, which is a preferable method.

The extraction is performed in the same manner as in the usual method of infusing tea or crude drugs, extracting coffee liquid, and making soup stock. That is, hot water or hot water is used, and the extraction time is usually 1 to 2 minutes. However, if the object to be extracted is not easily eluted, the extraction is performed under boiling conditions or the extraction is performed for several hours or more.

Although it is only nmol / mL, it is about 149-157 nmol / mL when taken together with green tea, coffee and turmeric tea,
It became clear that the amount absorbed in the body increases when used in combination with green tea or the like.

[0029]

The extract of the present invention, even when extracted using tap water containing residual chlorine and having relatively high hardness, reliably suppresses the chlorine odor and hardness of tap water due to the water quality improving effect of taurine. In order to reduce the taste, unpleasant taste and smell are effectively removed from the obtained tea, coffee, soup stock, and crude drug, thereby suppressing deterioration of the original taste of tea and the like. Since only a very small amount of taurine is used, it is very economical. In addition, the use of a very small amount of tasteless and odorless taurine does not affect the taste of foods and drinks at all.

The absorption of taurine having various useful medicinal effects into the human body is expected to have a great effect on health promotion. Compared to drinking taurine with water alone, tea, coffee,
Drinking with the extract of healthy tea increases the amount of absorption in the body, so that taurine can be ingested efficiently.
