BEST MODE FOR CARRYING OUT THE INVENTION
Regardless of the manufacturing method, dried barley leaf powder may be used.
Examples of barley include, but are not limited to, barley, wheat, rye, oats, and the like. The young barley leaves are preferably harvested before the maturation stage, that is, before the heading start stage (height is about 20 to 40 cm) from the splitting start stage. Among these wheats, young barley leaves are more preferably used.

The young barley leaves are preferably treated immediately after harvesting. When it takes a long time to process, it is stored by a storage means commonly used by those skilled in the art, such as low temperature storage, in order to prevent deterioration.

If necessary, the above-mentioned young barley leaves are washed with water (preferably cold water at 25 ° C. or lower) to remove mud and the like, and then drained, and then, if necessary, further to a suitable length (eg, , About 10 cm).

Next, a blanching process is performed on the young barley leaves.
The blanching treatment refers to high temperature treatment such as hot water treatment and steam treatment. Explaining the case of using hot water, young wheat leaves are, for example, 80 to 110 ° C., preferably 90 to 1
In hot water at 05 ° C., for 30 seconds to 10 minutes, preferably 1 to
It is performed by soaking for 5 minutes. The hot water used for blanching may contain 0.001 to 1% by weight of sodium chloride, an alkaline agent such as baking soda, calcium carbonate, calcium hydroxide, or both. As the calcium carbonate, commercially available calcium carbonate powder is used, but egg shell calcium, scallop shell calcium, coral calcium (dolomite) and the like can also be used.

By this blanching treatment, when young wheat leaves are made into a dry powder, the enzyme that causes fading is completely inactivated, so that the dry powder retains a bright green color. Also, the preference is retained.

Instead of the branching process, for example, Japanese Patent Laid-Open No.
Microwave treatment can also be performed as described in 2000-300209. The young barley leaf powder obtained by this treatment is superior in granulation property to the barley young barley leaf powder.

Before the blanching treatment, a treatment for increasing the amount of γ-aminobutyric acid (hereinafter referred to as GABA) contained in young wheat leaves and having a blood pressure lowering action (GABA).
Enrichment treatment) is preferable. For the GABA enrichment treatment, the method described in JP 2001-29041 A is adopted.

The GABA enrichment treatment is also carried out by immersing the young barley leaves in a liquid containing glutamic acid or a salt thereof (for example, sodium glutamate).
Glutamic acid or a salt thereof is preferably 0.01 to 40% by weight, more preferably 0.02 to 2% by weight based on young wheat leaves.
0 wt%, more preferably 0.05 to 10 wt% is added. Glutamic acid treatment is usually carried out at about 10 to 55 ° C, preferably 20 to 50 ° C, more preferably 25 to 50 ° C.
It is carried out at 45 ° C. The pH is usually 3.5 to 9.0, preferably 4.0 to 8.0, more preferably 4.5 to 7.0,
Most preferably, it is 5.0 to 6.0. The GABA enrichment treatment time is preferably 10 minutes to 24 hours. If it is carried out for 30 minutes or more, the GABA content will increase dramatically.

Since GABA is lost by the blanching treatment, it is preferable to carry out the GABA enrichment treatment beforehand so that a considerable amount of GABA remains after the blanching treatment.

Subsequently, the above-mentioned blanching-treated or microwave-treated young barley leaf has a water content of 10%.
Hereafter, it is dried to preferably 5% or less. As a drying method, for example, hot-air drying, high-pressure steam drying, electromagnetic wave drying, freeze-drying and the like can be performed by any method commonly used by those skilled in the art. Drying is preferably 50 to 9
It is carried out at 0 ° C., more preferably 55 to 65 ° C., for a time during which the young barley leaves do not discolor.

The dried young barley leaf is crushed by a machine or a tool commonly used by those skilled in the art, for example, a crusher, a mill, a blender, a stone mill, etc., to obtain a young barley leaf powder.

There is no particular limitation on the size of the young wheat leaf powder.
However, from a fine powder with a median diameter of around 20 μm,
Coarse powder with a diameter of about 250 μm, or the area of one side
5 mm ^TwoWheat of various sizes, up to small pieces
Young leaf powder is used.

The method for granulating young wheat leaf powder will be described below. Generally, as a method for granulating a food material, there are stirring granulation, fluidized bed granulation, extrusion granulation, tumbling granulation and the like. In the present invention, extrusion molding is used for granulation. By using the extrusion granulator, the young barley leaf powder can be granulated to have a hardness and size that induce chewing. In the granulation method using an extrusion molding machine, it is necessary to carry out a kneading step for making powder into a large mass, whereas in other granulation methods, mixing (mixing) and granulation corresponding to kneading are carried out. The difference is that the steps are performed simultaneously. By selecting the extrusion granulator,
The wheat leaf powder can be granulated without adding a binder or an excipient or by adding a small amount of a binder.

The dental caries preventive food of the present invention is obtained by mixing young wheat powder and water and kneading the mixture, and extruding the kneaded product.
Obtained by drying.

In addition to water, ethanol can be added to adjust the texture of the granulated product.

The mixing ratio of the young barley leaf powder and water is preferably 10 to 50 parts by weight, preferably 10 to 30 parts by weight, relative to 100 parts by weight of the young barley leaf powder. And the ethanol added as needed is 1 to 40 parts by weight, preferably 1 to 20 parts by weight. When water and ethanol are used together, a total of 10 parts by weight to 100 parts by weight of young barley leaf powder is used.
.About.50 parts by weight, preferably 10 to 30 parts by weight.

In order to increase the number of times of chewing or to make the texture hard, the amount of ethanol added is suppressed, and the pressure applied during compression is further increased. On the other hand, in order to make the granulated material easily break in the mouth due to chewing, the ethanol content is increased. However, even when the ethanol content is increased, it is preferable to control the water: ethanol ratio to about 1: 3 by weight.

The dental caries preventive food of the present invention does not require any binder other than water or water and ethanol. But,
Granulation becomes more difficult as the size of the young barley leaf powder generally used increases, so a binder may be added to facilitate granulation. As the binder, a natural material is preferable, and pregelatinized starch that acts as a sizing agent, indigestible dextrin, oligosaccharide, sugar alcohol and the like are preferably used.

By using the pregelatinized starch, the hardness can be increased while the amount of the binder used is suppressed.

The indigestible dextrin plays a role of glue and at the same time, the material itself has a function. The functions of the indigestible dextrin include, for example, intestinal regulating action and suppression of rapid increase in postprandial blood glucose level.

As the oligosaccharide, for example, milk fruit oligosaccharide, galactooligosaccharide and fructooligosaccharide are preferably used. As other oligosaccharides, lactulose, palatinose, raffinose, stachyose, xylooligosaccharides, maltooligosaccharides, isomaltooligosaccharides, chitin oligosaccharides, chitosan oligosaccharides, trehalose and the like can be selected.

These oligosaccharides are assimilated by the beneficial bacteria in the intestine to bring about an intestinal regulating action, and in combination with dietary fiber of young wheat leaves, a synergistic intestinal regulating effect is obtained. Furthermore, the use of non-cariogenic oligosaccharides such as palatinose, trehalose, fructooligosaccharides, xylooligosaccharides and milk fruit oligosaccharides is useful as a food for preventing dental caries.

Examples of sugar alcohols include xylitol, maltitol, erythritol, lactitol, sorbitol and the like. Among these, xylitol has an anti-cariogenic property and is preferably used.

These binders are added in an amount of 1 to 30 parts by weight based on 100 parts by weight of young barley leaf powder. The binder may be used alone or in combination of two or more. To increase the hardness, the amount of the binder added may be increased. When it is desired to further increase the hardness, the hardness can be increased by adding it in the range of 30 parts by weight or more. Also, the binder may be mixed in advance with young barley leaf powder,
You may add what melt | dissolved in water or ethanol or its mixed liquid. Then, the granulated product of the present invention has, for example, the following formulation examples (the numbers are parts by weight): Young barley leaf powder: pregelatinized starch = 98: 2 Young barley leaf powder: indigestible dextrin = 90:10 Wheat Young leaf powder: maltitol = 90: 10 Then, for example, 20 parts by weight of water and 2 parts by weight of ethanol are added to 100 parts by weight of the mixture.

Further, by adding calcium,
Not only the granulation property is improved and the surface of the granulated product is adjusted, but also the chewy texture is improved, so that the number of times of chewing is increased, and a further caries preventive effect can be expected. As calcium to be added, calcium derived from natural products such as egg shell calcium, scallop shell calcium and coral calcium (dolomite) is preferably used.

When water and ethanol are used, there is no particular order of addition of the young barley leaf powder, water and ethanol, and they may be added in the order of water, ethanol or vice versa.
Alternatively, a mixed solution of water and ethanol may be added. These materials and, if necessary, a binder are put into a mixer and mixed and kneaded. The mixer may be installed in the extruder.

The dental caries preventive food of the present invention comprises granules of young barley leaf powder. The young barley leaf powder contains abundant dietary fiber, and a tooth decay preventive effect can be obtained due to the requirement for mastication of the granulated product. That is, in the conventional granules and tablets, since they were swallowed without being chewed, the dietary fiber of young wheat leaf powder was eaten without contact with the teeth. On the other hand, since the food for preventing dental caries of the present invention is chewed, the dietary fiber of the young barley leaf powder is entangled with the teeth, and the dental plaque and food waste are swallowed while being absorbed and adsorbed. Furthermore, chewing promotes saliva secretion, which is excellent in preventing tooth decay.

As described above, the dental caries preventive food of the present invention may be composed of only wheat barley powder, but may contain other food materials. For example, the dental caries preventive food of the present invention may further contain other components having a dental caries preventive effect, if necessary. This can enhance the caries preventive effect.

Other components having a caries preventive effect include:
Examples include lactic acid bacteria, anticaries agents, antibacterial agents, and other insoluble dietary fibers. Among these, preferable are lactic acid bacteria and anticaries agents, and xylitol, which is also used as a binder, is particularly preferable.

Lactic acid bacteria can suppress the growth of periodontal disease bacteria and at the same time suppress the activity of enzymes that destroy the periodontium, thereby enhancing the caries preventive effect.

Examples of the anticaries agents include crude drug tannins, ellagic acid, green tea polyphenols, oolong tea extract, fruit polyphenols and the like. These anti-caries agents have the effect of preventing the development of caries by inhibiting the activity of glucosyltransferase, which is an enzyme that synthesizes glucan that causes caries, and the addition of these agents enhances the caries preventive effect. You can

As the antibacterial agent, for example, extracts such as kobishi, saishin, salmon, perilla, ginger, dill, thyme, rosemary, oil-soluble Amakusa extract, ascorbic acid, mutasteine, humic acid, linoleic acid,
Examples thereof include linolenic acid. These antibacterial agents inhibit the growth of periodontal disease bacteria. By adding these, the caries preventive effect can be enhanced.

Examples of the other insoluble dietary fiber include wheat bran, beet fiber, corn fiber, apple fiber, lignin, chitin, chitosan, calcium alginate, yeast cell wall and the like. These insoluble dietary fibers, in combination with dietary fiber of young wheat leaf powder during chewing, enhance the caries preventive effect. That is, the amount of dietary fiber swallowed is increased while being entangled with the teeth, plaque and dusts of food are absorbed and adsorbed, and the effect of preventing dental caries can be enhanced.

The other components having such a caries preventive effect may be in the form of powder, liquid or the like, and may be added in an amount of 0.01 to 30 parts by weight based on 100 parts by weight of young barley leaf powder.

In order to further induce mastication, it is preferable to add mushrooms, peanuts, sesame, yeast (including yeast extract), etc. to the dental caries preventive food of the present invention. In the case of peanuts, sesame, etc., paste It is preferable to use the shape. For paste-like peanuts or sesame, the viscosity during extrusion can be adjusted. For example, if a large amount of indigestible dextrin, which is a binder, is added for the purpose of functioning and the viscosity becomes too high, these may be added to adjust the viscosity.

When a material other than the young wheat leaf powder is blended, the addition amount of water or ethanol or a mixed solution thereof is calculated by considering the total amount of the other materials and the young wheat leaf powder as the solid content. The addition amount is the same as above with respect to 100 parts by weight.

The kneaded product obtained by kneading as described above is
Then, the mixture is granulated by using an extrusion molding machine. For the extrusion molding, an extrusion molding machine used for producing foods, pharmaceuticals and the like is preferably used, and an extrusion molding machine such as a screw type, a roll type, a blade type, a self-forming type and a ram type is used. A screw type extruder and a blade type basket type extruder are preferably used.

When granulation is carried out using a screw type extrusion molding machine, granulation of various shapes is possible by making the shape of the die circular, rectangular or the like. The extrusion molding machine of this type extrudes the kneaded material from the hole of the die while compressing and kneading the kneaded material in the feeding section. Examples of such an extrusion granulating apparatus include an EXD series apparatus (for example, EXDS-60) manufactured by Fuji Paudal Co., Ltd. This extruder is preferably used when obtaining a relatively large granulated product having a pore size of about 7 to 10 mm, but it requires cutting after granulation.

Further, an F series disc pelleter device (for example, F-5) manufactured by Fuji Paudal Co., Ltd. is also preferably used. This device is preferably used when obtaining a relatively large granulated product having a pore size of about 7 to 10 mm.
Further, since this apparatus generates heat of compression, the granulating property is improved, and further, since the apparatus is equipped with a cutter, a granulated product having a regular size can be obtained. Particularly, when starch is used as the binder, it is convenient because the binding property can be improved by heating.

Even if a basket-type extrusion granulator is used, granules of young barley leaf powder having various sizes can be obtained by changing the pore size of the screen. When using a basket-type extrusion granulator, first, water and ethanol, if necessary, a binder is added to the wheat barley powder, and the mixture is kneaded to form the barley grass powder into a lump, and the mixture is extruded under pressure from a screen. , Granulate. The hole diameter of the screen is not particularly limited, but the size may be changed according to the purpose, such as 3 to 10 mm. For example, a device of the BR series of Fuji Paudal Co., Ltd. may be mentioned.

The obtained green barley leaf granules are then dried. Drying is performed at 70 ° C. or lower, preferably 65 ° C. By maintaining the temperature at 70 ° C. or lower, a granulated product having an appropriate hardness can be obtained without impairing the nutrient content of young wheat leaves. In order to obtain a slightly hard granulated product, it is advisable to carry out at 70 ° C.
Further, in order to increase the hardness of the granulated product, the amount of the binder added may be increased. Furthermore, the initial temperature is, for example, 70
It is also possible to harden the surface by setting the initial temperature to a relatively high value such as by gradually lowering the temperature to 65 ° C. by setting the initial temperature to 65 ° C. in this way,
The texture can be changed depending on the drying conditions.

The drying time varies depending on the drying temperature and the size of the granulated product. For example, when the granulated product obtained using a basket type extrusion granulator having a 5 mm screen is dried, it is sufficient to perform the granulation at 65 ° C. for 15 hours, and it may be appropriately determined while checking the degree of drying. .

The obtained granules have different textures depending on the size of the young barley leaf powder used. For example, the median diameter is 20μ
Granules obtained from fine powder of around m have a texture that the whole will collapse if you chew it lightly several times in the mouth, and if you use coarse powder with a median diameter of about 250 μm, it will chew slightly and crumble. It has such a texture and induces chewing more than fine powder. The granulated product granulated from the crushed pieces has a chewy texture. Needless to say, the barley leaf powder can be granulated if it has a size between the fine powder and the crushed pieces. In addition, in the case of granulating a large barley leaf powder, it is preferable to appropriately mix the fine powder or the coarse powder from the viewpoint of granulation. The blending ratio of these may be appropriately adjusted while observing the degree of granulation.

The shape and size of the granulated product are not limited,
The block shape and the pellet shape are preferable. The size is a size that can be chewed, and the size of the shortest part of the shape can be 2 mm or more, 4 mm or more, 5 mm or more, 7 mm or more, or 10 mm or more. If a preferable range is determined according to the purpose and application. Good. The granulated product is formed into a size that is easy to eat, and preferably has a volume of 15 mm ³ or more.

The thus-obtained granules of young barley leaf powder are directly stored in an aluminum pack or the like. The storage condition is good, and the flavor and green color do not change even when left in an incubator at 40 ° C and a humidity of 70 to 75% for 1 month or stored in a cool dark place (10 ° C) for 1 month.

The dental caries preventive food of the present invention, which comprises the granulated product of young barley powder, can be eaten as a food as if it were a sweet. In addition, it has an excellent effect such that it has a pleasant mouthfeel, and the function of the brain is improved by chewing it many times, the components of the young barley leaves adjust the physical condition, and the bowel movement is improved. When granulating by adding ingredients with a caries preventive effect,
The tooth decay prevention effect is further enhanced.
