BEST MODE FOR CARRYING OUT THE INVENTION The black wheat used as a raw material in the present invention is a wheat whose epidermis is dark brown. Milling and removing the epidermis results in a grayish white flour. Whole flour is darker brown than normal flour. Famous production areas include Heilongjiang Province, China. Preferred varieties include Takashi Kuro (registered trademark). The black wheat used in the present invention may be not only wild varieties that have not been bred by crossing, such as, for example, Black Princess, but also varieties or varieties that have been bred by crossing with normal wheat, for example. . The black wheat used in the present invention includes proteins and amino acids such as glutamic acid, glycine, aspartic acid, alanine, and cysteine in larger amounts than ordinary wheat, and wheat whose epidermis is darker brown than ordinary wheat. preferable.

The health drink of the present invention is produced, for example, as follows. Water temperature for soaking black flour in water is about 10
At 40 ° C., the immersion time is about 20-50 hours. After the immersion, draining (dehydration) is performed, and the root is rooted by leaving to stand to obtain rooted wheat. The standing time is usually about 5 to 35 ° C, and the time is about 24 to 40 hours. Malt treatment of the thus obtained rooted barley yields malt of black wheat. The malting treatment is performed by storing the rooted wheat in an atmosphere having a relative humidity of preferably 60 to 100% at a temperature of about 10 to 30 ° C. for about 2 days to 1 week.

The malt of black wheat thus obtained is obtained and then dried to obtain a dry malt. Drying conditions are preferably at a temperature of about 10-45 ° C., about 30-70%
, And the number of dry days of about 2 to 7 days. The dried malt thus obtained is roasted to obtain roasted malt. The roasted malt is preferably ground (roughed) or pulverized by mechanical means (for example, a cutter, crusher, ball mill, grinder, etc.) to obtain a ground or pulverized roasted malt. 1) Malt of black wheat, 2) dried malt, 3) roasted malt or 4) ground black malt, dried malt or roasted malt can be subjected to an extraction treatment to obtain an extract. For the extraction, the above 1) to 4) are extracted by water, steam, a hydrophilic solvent (for example, ethanol), or a mixture of water and a hydrophilic solvent by an ordinary method to obtain an extract.

The thus produced 1) black wheat malt, 2) dried malt, 3) roasted malt or 4) black wheat malt,
Foods containing ground or crushed dried malt or roasted malt or the extract of 1), 2), 3) or 4) are rich in γ-aminobutyric acid and useful as functional foods. The food is a liquid or solid food, and may have any shape. More specifically, such health foods include drinks, breads, confections, noodles, tempura, fries, and the like, and the above-mentioned materials 1) to 4) can be used in all kinds of foods and dishes.

Next, a specific example of the production of healthy tea will be described. The ground roasted malt produced through the black wheat malt, dried malt, and roasted malt produced as described above is subjected to an extraction treatment with water or steam. The water is preferably hot water or hot water, and the temperature is usually 60 to 100 ° C. High-temperature high-pressure steam may be used instead of hot water or hot water. Hot and high pressure steam extraction may be performed in a manner similar to making espresso from roasted coffee beans. When the water extract thus obtained is cooled to, for example, 5 to 15 ° C., a health drink having an excellent flavor can be obtained.

In the method for producing a health drink of the present invention described above, the ground roasted barley tea is extracted with water or steam. The health drink of the present invention is obtained by drying dried malt or roasted malt with water or steam. And may be manufactured by extraction.

The health drink of the present invention may also be obtained by suspending fine powder obtained by pulverizing the above-mentioned roasted malt or dried malt in hot or cold water and cooling it if desired.
The health drink obtained by the above example can be enjoyed instead of tea, and may be referred to as health tea. Further, the health beverage of the present invention may optionally contain other components such as a sweetener, a sugar,
Vitamins, amino acids, minerals, colorings, preservatives,
It may contain a fragrance or the like.

In the above-mentioned production process, particularly, rooting and / or
And in the germination step, the protein contained in the black wheat grains, particularly in the germ portion thereof, is changed to glutamic acid by the hydrolase contained in the black wheat, and glutamic acid is further converted to γ- by the action of an enzyme (for example, glutamate decarboxylase).
Changes to aminobutyric acid. Since black wheat contains a high content of protein, the above malt or dried malt has a high content of γ.
-Contains aminobutyric acid. The γ-aminobutyric acid thus enriched in content is then contained in the above-mentioned health drink via roasted malt and its ground products. Therefore, the content of γ-aminobutyric acid is much more enriched in the beverage of the present invention than in the raw black wheat grains through such a chemical reaction. Since γ-aminobutyric acid is known to have the following pharmacological actions or life-improving actions, the health drink of the present invention has excellent 1) hypotensive action, 2) renal function activating action,
It shows 3) liver function improving effect, 4) obesity preventing effect, 5) alcohol metabolism promoting effect and 6) deodorizing effect.

The same applies to health foods other than health tea. For example, 1) black wheat malt of the present invention,
2) dried malt, 3) roasted black wheat malt or dried malt (roasted malt), 4) black wheat malt, dried malt, ground roasted malt (ground malt) or ground product, 5) 1 ), 2),
Breads enriched in γ-aminobutyric acid can be produced by using the extract (extracted malt) of 3) or 4) as one of the raw materials according to a conventional method. More specifically, breads may be manufactured according to a conventional method. For example, kneading flour with water, yeast food, yeast and the like to knead it into middle noodles,
5) kneading the bread dough by adding black wheat malt or a material derived therefrom and auxiliary materials such as sugar, salt, skim milk powder, shortening and water, and fermenting the kneaded bread dough By the production method including the step of baking, breads rich in γ-aminobutyric acid and rich in γ-aminobutyric acid can be easily produced.

Regarding the blood pressure lowering effect, γ-aminobutyric acid suppresses the secretion of vasopressin, dilates blood vessels and lowers blood pressure. Regarding activation of renal function, γ-aminobutyric acid lowers BON (urea nitrogen) level and suppresses necrosis of renal basement membrane cells. Regarding the liver function improving effect, γ
-Aminobutyric acid lowers the activity of alkaline phosphatase (ALP) and transaminase (GPT), so that it can be expected to have a favorable effect on activation of liver function. For the prevention of obesity, γ-aminobutyric acid prevents obesity by lowering triglyceride (TG) in the liver and blood. Regarding alcohol metabolism, γ-aminobutyric acid remarkably suppresses an increase in transaminase (GPT) and thus prevents a decrease in liver function, thereby promoting metabolism of alcohol in the body. As for the deodorizing effect, γ-aminobutyric acid has an effect of deodorizing unpleasant odors such as mercaptans such as methyl mercaptan and ammonia.

It is said that in modern people, adult diseases such as obesity caused by chronic lack of exercise, high levels of stress, disturbed eating habits, and satiety are increasing, and symptoms of adult diseases are beginning to appear even among young people. The health food of the present invention is useful as a functional food for preventing such adult diseases or improving life.
