Abstract

PROBLEM TO BE SOLVED: To provide barley tea extracted by water, becoming barley tea beverage presenting real color and flavor without waiting by stirring in room temperature water, and to provide a tea bag storing the barley tea.SOLUTION: The barley tea is obtained by mixing pregelatinized roasted barley and charbroil roasted barley, bringing an L value of the mixture in a Lab color system to ≤31 by adjusting the roasting degree of the roasted barley before mixing, and grain refining bath roasted barley before and after mixing followed by bringing to barley tea including ≥70 wt.% of barley of <10 mesh particle size. As a result of this, the barley tea is used as it is or by storing in a tea bag, as the barley tea extracted by water. The mixture contains 5-30 wt.% of the pregelatinized roasted barley, and 70-95 wt.% of the charbroil roasted barley.

Description

  The present invention relates to watering barley tea, and more particularly, to watering barley tea that can bring out the color and taste of full-fledged barley tea in a short period of time without making you feel waiting while drinking.

  As a conventional tea for draining, a tea component extraction solution obtained by extracting a soluble tea solid content from tea leaves with hot water is used as it is by concentrating and drying, freeze-drying, or the tea component extraction solution, sugar, Using instant tea powder obtained by adding various flavoring agents such as lemons, hackers, peaches, etc., followed by concentration drying, freeze drying, etc. The invention which devised the tea bag which put the tea leaves in the shape is disclosed.

  For example, Patent Document 1 discloses the instant tea powder containing tea leaves in order to improve the flavor of the instant tea powder, and Patent Document 2 discloses tea such as green tea, black tea, oolong tea, and roasted tea. There are disclosed teas in which 10% by volume or more of bubbles are mixed in the component extraction solution after freezing, and then freeze-dried in vacuum, and instantly soluble powder is disclosed. In both cases, tea components are extracted from tea and dried. Since it is a product, it has not only a problem in flavor, but also has a drawback that it takes a lot of labor and cost.

  Further, Patent Document 3 discloses a green tea, black tea, oolong tea, or other tea leaf or herb fine powder package having a particle size of 1 to 40 microns and a hot water that does not require hot water, which is stored in a container. A tea drinking kit that can obtain a tea drinking solution in time is disclosed, but it is unclear how much time is short, and the taste of tea is unknown.

  Furthermore, Patent Document 4 discloses that tea that can be drained and that can be easily prepared through the throat can be easily prepared, can be easily handled and can be easily adjusted to the desired strength, and leaves no nutrients in the tea leaves. A flat tea bag that can be ingested is disclosed, and tea leaves stored in the flat tea bag include tea leaves such as green tea, black tea, oolong tea, etc. in which 90% or more of the particle size distribution is in the range of 10 to 300 μm Fine powder is described. However, in this case as well, it is described that the tea bag can be drained by making it flat (paragraph 0022), but the degree of solubility in water, the taste of tea, etc. are unknown. .

  On the other hand, for barley tea made from barley and the like instead of tea leaves, instant barley tea that uses oligosaccharides or the like as the flavor is on the market for water drainage. This is similar to the instant tea powder described above. Not only does the extraction and drying of the components take much time and cost, but there is also a problem of impairing the original flavor of barley tea. In addition, barley tea bags for watering and hot water are on the market, but when using room temperature water, it takes several hours before tea can be drunk. . Moreover, tea that is used in combination with hot water discharge and pursues only water discharge in earnest cannot be found in the market except for the instant wheat tea.

  By the way, when it comes to tea, PET bottle drinks, including barley tea, are now popular, and the market share is large. Prior to the spread of PET bottle tea beverages, it was natural to brew tea leaves with teapots, but tea bags that evolved from tea bags were not used for tea chase processing and so on. It was. However, it can be said that its share in the market is much smaller than that of plastic bottle drinks.

  In terms of cost, in the case of plastic bottle drinks containing barley tea, if purchased at a supermarket etc., it will cost more than 150 yen per 500ml size and 200 yen per 2 liter size. A product with 50 bags of tea bags for 1 liter is about 200 yen, 8 yen to make 2 liters of tea, and other costs are estimated within 20 yen. The cost is / 10.

  However, the proportion of plastic bottle drinks in the market is that for tea bags, it takes time to boil hot water, and even if it is a water discharge type, it takes a waiting time that exceeds the limit before drinking tea. It seems that there is a point. For example, for tea bottle drinks that can quickly dry your thirst when you come home from the outside on a hot summer day, tea bag tea takes time to boil hot water and cool, and you can use it as a draining type. However, it takes about 1 to 3 hours to drink. This means that no matter how much the cost is dramatically lower, the convenience of PET bottles cannot be countered.

  Therefore, if a full-fledged barley tea for brewing can be made immediately when it is desired to drink, it will match the needs of consumers, and it will also contribute greatly to society as shown below. In other words, since PET bottle barley tea is heavy, it requires considerable effort to purchase and take it home at a mass retailer.Plastic bottle containers that have been emptied after drinking are subject to separation and cannot be disposed of at all times and are disposed of. At the same time, the burden on the environment is large, but if you have the above-mentioned full-fledged barley tea for draining water and the tea bag that contains it, you do not need a plastic bottle, it is lightweight, and you use a plastic bottle. Even when the barley tea for draining or the tea bag is stirred or shaken in a water-filled PET bottle to make a barley tea beverage, the same PET bottle can be used any number of times. Etc. are considered to be eliminated at least for barley tea.

JP-A-11-2221018 Japanese Patent No. 2788157 Utility Model Registration No. 3089566 JP 2009-60826 A

  The present invention has been made in view of such circumstances, and when stirred in room temperature water, it becomes a barley tea beverage that exhibits a full-fledged color and flavor without waiting. The object is to provide a bag.

  This inventor repeated a series of researches in order to achieve the said objective. And, in the case of roasting method of raw material wheat and barley tea, it has been said that, if the grain size of the wheat is too fine, the taste and miscellaneous taste will come out, and various investigations including the field of particle size distribution that was viewed taboo, Finally, the barley tea ingredients with a specific particle size distribution and color of a mixture of pregelatinized roasted barley and charcoal roasted barley are extracted easily with room temperature water, and full-fledged color and flavored barley tea It discovered that it became a drink, and completed this invention.

  That is, the first invention of the present invention is a mixture of pregelatinized roasted wheat and charcoal roasted wheat, the mixture containing 70% by weight or more of particles having a particle size of less than 10 mesh. The barley tea for draining is characterized in that the L value in the Lab color system is 31 or less.

  The mixture may contain 70% by weight or more of particles having a particle size of less than 10 mesh, preferably 75% or more or 80% by weight or more of particles having a particle size of less than 10 mesh, more preferably 85% by weight. It is good to contain more than 90 weight%. Furthermore, it is preferable that 40 to 65% by weight of a product having a particle size of less than 10 mesh is contained in a proportion of the total amount of barley tea. The mixture preferably contains only those having a particle size of less than 5.5 mesh, and preferably does not contain any product having a particle size of 5.5 mesh or more. In the present invention, the particle size is described later. It is a value measured by the “sieving method”.

  Here, barley, barley, rye and the like are included in the wheat, but barley is preferably used. Also, pregelatinized roasting is a known method of steaming wheat raw material before roasting and drying and then hot-air roasting. Charcoal roasting is a known method using charcoal as fuel in a roasting machine. It is a roasting method. Barley tea is usually roasted with hot air using raw oil, mainly heavy oil, kerosene, gas, etc. as the fuel. For the watering barley tea according to the first invention, the above-mentioned two known methods are selected. Using roasted wheat, adjusting the degree of roasting of the wheat before mixing and adjusting the degree of pulverization of the wheat before and after mixing, and containing 70% by weight or more of the mixture whose particle size is less than 10 mesh The L value in the Lab color system of the mixture is 31 or less.

  The color of the mixture (depending on the roasting degree) is such that the L value in the Lab color system is 31 or less, preferably 29 or less, more preferably 27 or less. Here, the L value in the Lab color system represents “brightness”, and the larger the value, the stronger the lightness. Therefore, the smaller the value, the weaker the lightness and the darker the roasting degree. In the first invention, when the L value is 31 or less, when the water is discharged, the color of the water quickly becomes so-called wheat brown, and it is possible to enjoy authentic wheat brown.

  According to the first invention, as will be described later, the color of a full-fledged barley tea beverage with a room temperature water of about several tens of seconds to a few minutes, and the flavor as a barley tea with a good throat and good cut (full-fledged flavor) ) Is drawn, but this is a mixture of the wheat that has been soaked in water, steamed and roasted for a predetermined period of time, and the roasted barley that has been roasted for a predetermined period of time using far-infrared rays using charcoal fire to obtain an L value within a predetermined range. As a result, ingredients that have a positive effect on the taste of the drained barley tea beverage (boiled and lightly mellow taste, etc.) and color are produced in the mixture. It is thought that it is due to the fact that the ingredients that give the color and flavor of full-fledged barley tea beverages are easier to dissolve in room temperature water, working together with the improvement in water solubility due to the particle size distribution that was made It is done.

  According to a second aspect of the present invention, in the mixture, the content of pregelatinized roasted wheat is 5 to 30% by weight, and the content of charcoal roasted wheat is 70 to 95% by weight. A barley tea for draining according to the first or second aspect of the invention.

  By setting it as such a mixing ratio, the taste and color of the drained barley tea beverage can be made more preferable. The content of pregelatinized roasted wheat is preferably 10 to 20% by weight, and the content of charcoal roasted wheat is 80 to 90% by weight.

  A third invention of the present invention is a tea bag containing the barley tea for draining according to the first or second invention, and the fourth invention is a third bag containing 7 to 11 grams of barley tea for draining. A kit for barley tea for draining comprising a tea bag according to the invention and a plastic container of 1.5 to 2.5 liters.

In the fourth invention, the relationship between the amount of barley tea stored in the tea bag and the volume of the container is appropriate for extracting the color and flavor of the barley tea beverage, and the container containing the tea bag and water is shaken about 50 times. By leaving the 50-vibration container for about several minutes thereafter, a barley tea beverage with a preferred color and flavor can be made immediately. As a plastic container, an empty state is preferable for convenience of carrying, but it is needless to say that it may be filled with water. The drained barley tea contained in the tea bag is preferably 8 to 10 grams. As for tea bags, when draining water, (1) there are no health-damaging ingredients in the tea bag material, and (2) fine particles with a size that adversely affects the throat and sharp barley tea beverages. It is preferable to use a tea bag (for example, having a basis weight of about 18 g / m ² ) having micropores that can prevent the passage of water. Examples of tea bags that satisfy (1) and (2) include tea bags made of unbleached paper (9018H 2000 manufactured by Miki Tokushu Paper Co., Ltd.).

As detailed above,
According to the barley tea for water drainage of the first invention, when water is drained by stirring or the like using room temperature water, the color of the aqueous solution quickly becomes so-called wheat brown in about several tens of seconds to several minutes. You can enjoy the typical wheat brown and flavor,
According to the barley tea for draining of the second invention, the color and flavor of the drained barley tea can be made more preferable. Also,
According to the third aspect of the invention, there is provided a barley tea-enclosed tea bag for watering that prevents barley tea particles having a size that adversely affects the throat and sharpness from being mixed into the barley tea beverage and can further improve the flavor of the tea.
According to the fourth aspect of the invention, the relationship between the amount of barley tea stored in the tea bag and the volume of the container is suitable for quickly drawing out the color and flavor of the barley tea beverage and is convenient to handle in ordinary households. A kit product for barley tea for serving can be provided.

Furthermore, the barley tea according to the present invention is considered to contribute to society in the following respects with respect to the plastic bottle drink.
(1) Adjust the amount of water, you can drink your favorite tea.
(2) As described above, it is possible to provide a low cost product of 1/10 of a plastic bottle beverage.
(3) Since PET bottle drinks are heavy, considerable effort is required to purchase them at a mass retailer and take them home. However, there is no need to buy or buy PET bottle drinks with such burdens for couples working together or aging households. It becomes.
(4) Since the plastic bottle can be reused, contribution to the environment can be realized by releasing the troublesomeness when disposing of the empty plastic bottle container and reducing the container of the used plastic bottle.

  Next, the present invention will be described in more detail with reference to examples. However, these are only specific examples for implementing the present invention and results (effects) thereof, and the present invention is not limited to these examples. There are no restrictions.

Example 1
Raw barley is soaked in water for 15 hours, drained for 3 hours, steamed with steam at 100 ° C or lower for 30 minutes, then roasted with hot air at 195 ° C to 320 ° C for about 5 minutes, cooled, and its color is 23 Among the pregelatinized roasted barley with an L value of ˜26.99, 15% by weight of the pregelatinized roasted barley with an L value of 26.5 (eg, pregelatinized roasted ST50α manufactured by Sakai Shoten Co., Ltd.) The raw barley was baked and roasted at 250 ° C. to 280 ° C. for 20 to 40 minutes and then cooled, and the L value was 26.1 out of the charcoal baked roasted barley that had an L value of 23 to 29.99 as its color. Charcoal-roasted roasted barley (for example, ST50 charcoal made by Sakai Shoten Co., Ltd.) was mixed with 85% by weight.

  Next, this mixture was pulverized using a grinder (Yamamoto Iron Works Co., Ltd. Maruroku Flour Mill Milton Model A, Kawaguchi City). This grinder inserts a male mortar with a groove on the outer wall into a female mortar with a groove on the inner wall, rotates both sides in the opposite direction, and grinds the barley put between the two mortars. Turn the inner male mortar into the back and let it approach with a female mortar. The barley becomes finer, and if you lower the degree of access to the female mortar, the barley becomes coarser, so the barley grain size can be adjusted with this handle. In this embodiment, this handle is adjusted to a position rotated 6.5 times from the reference position (0 position), and the mixture is ground at room temperature (particularly the temperature at which it is not cooled or heated). A barley tea having a particle size distribution was obtained. In addition, the grinding | pulverization means of the barley tea raw material for obtaining the barley tea of the particle size distribution based on this invention is not specifically limited, Of course, conventional grinding | pulverization means, such as a stone mill, a ball mill, a jet mill, and a pin mill, can be used.

(Example 2)
Particle size, L value, density of barley tea obtained in Example 1 and barley tea of Company A (Comparative Example 1) and barley tea of Company B (Comparative Example) marketed for watering out and hot water (or boiled) Table 2 shows the particle size, L value, and density of 2) measured three times, and the measurement results and their average values are compared and described.

here,
(1) The particle size was measured by a so-called “sieving method”. Weigh 100g of sample, put it on top of “Sieving” which is 5.5, 7.5, 10 and 14 mesh, and use electromagnetic vibration sieving machine (Seishin Co., Ltd., model number OCTAGON DIGITAL CE). For about 10 minutes, and the weight of the raw material remaining on each sieve was measured. In Table 1, ON indicates the remaining amount on the mesh, and PASS indicates the passing amount to the mesh. The unit of the numerical value representing the remaining amount and the passing amount is weight% ((g / 100 g) × 100). The “sieving” standards used are as follows.
・ 5.5 mesh sieve: height 25mm, opening 3.35mm, line length 1.5 ~ 1.06mm
-7.5 mesh sieve: height 25mm, opening 2.36mm, line length 1.15 ~ 0.85mm
・ 10 mesh sieve: height 45mm, opening 1.7mm, line length 0.92 ~ 0.68mm
・ 14 mesh sieve: height 45mm, opening 1.18mm, line length 0.72 ~ 0.54mm
・ Inner diameter (diameter) is 200mm for all sieves.

(2) L value was measured as follows using the sample which was not used for the screening of (1) among the samples of Example 1, Comparative Example 1 and Comparative Example 2. After the object to be measured is pulverized with a 4-blade mill, the powder that has passed through a 60-mesh wooden sieve is put into a 9.8 ml round cell for measurement, and a colorimetric color difference meter (manufactured by Nippon Denshoku Co., Ltd.) is used. The model number was measured using ZE2000). The measurement was performed three times, and the L value obtained by calculating the average value is shown in Table 2, Example 1. As described above, the L value represents “brightness”, meaning that the larger the value, the stronger the lightness. Therefore, the smaller the value, the weaker the lightness and the darker the roasting degree. .

(3) The density was measured by taring the weight of a 200 ml sample using a 200 ml graduated cylinder (glass graduated cylinder manufactured by Shibata Kagaku Co., Ltd.). The density (g / 200 ml) of the barley tea of Example 1 is 77.3 on an average of three occasions. In the present invention, it is preferable to use barley tea particles having a density (g / 200 ml) of 70 or more, more preferably 75 or more.

  The barley tea of Example 1 contains 93.3% by weight of the average particle size of less than 10 mesh and the L value is 26.2, whereas Comparative Example 1 has a particle size of less than 10 mesh. Is only 45.1% by weight in an average of three times, the L value is 33.7, and Comparative Example 2 contains only 59.2% by weight in an average of three times less than 10 mesh. The L value is 33.6. Therefore, the type and processing method of the wheat of the comparative example are unknown, but a clear and large difference is observed in the particle size distribution and L value between the barley tea of the comparative example and the barley tea of the example.

(Example 3)
Sensory evaluation was performed about the color and taste of the barley tea of Example 1 and the barley tea of Comparative Example 1 and Comparative Example 2. Each of these barley teas is placed in a tea bag of the same material and size (9018H 2000 made by Miki Tokushu Paper Co., Ltd.), and each tea bag is in a 2 liter screw cap bottle containing 2 liters of water. The bottle was manually shaken 50 times at 20 ° C. The panelists of Group A (GA), Group B (GB), and Group C (GC) determined the color and taste of the drained barley tea beverage obtained immediately after shaking.

  GA, GB, and GC are separate groups in different regions and workplaces. GA is composed of 10 people, GB is composed of 10 people, and GC is composed of 7 people. The panel of each group does not show the display of Examples or Comparative Examples on the drained barley tea beverage immediately after shaking 50 times, and the color and taste of the drained barley tea are 1 to 5 based on the five-step evaluation shown below. We asked them to enter a score of up to 5. Table 2 shows all of the paneler evaluation results of each group and the average value of the paneler evaluation results of each group for the barley tea of Example 1 and the barley teas of Comparative Examples 1 and 2.

Here, each score means the next evaluation.
5: Color or flavor comparable to boiled barley tea or PET bottle barley 4: Color or flavor quite close to boiled barley tea or PET bottle barley 3: Color or taste intermediate between 3: 5 and 1 About the color or flavor 2: Although both the color and taste are still faintly felt, the taste can be felt as wheat brown, the taste of barley tea 1: There is almost no coloring, the taste is too much to drink water Taste that doesn't change

  Regarding the color of the barley tea beverage of Example 1, the average value of each of the three groups is 3.3, 4.1, and 3.9, and the average value of the entire three groups is 3.8. Similarly, the average value of all three groups of the color of Comparative Example 1 is 2.0, and that of Comparative Example 2 is 1.4.

  Speaking of the color of barley tea beverage, the barley tea of Example 1 according to the present invention is extracted with water at room temperature (20 ° C.) significantly earlier than the commercial product, and becomes 3.8 after 50 shakes. In other words, the color of the comparative example is 2.0 and 1.4, while the color is close to full-fledged wheat brown. Due to the difference in the extraction speed, the difference in the degree of coloring of the drained beverages of the example and the comparative example becomes larger as time passes. In fact, the tea bag of Example 1 is in a state where it sinks when placed in water, but the comparative example is in a floating state, and both have a difference in terms of affinity with water. It is clear from this that the sample of Example 1 is easy to extract.

  These differences in the color of the barley tea beverage between the examples and the comparative examples are considered to be largely influenced by the difference in the processing methods of both, but such differences cannot be considered because the processing method of the barley tea in the comparative examples is unknown. As well as the difference in L value, the difference in both particle sizes, or the difference in both densities considered to reflect the difference in both particle size distributions (the density (g / 200 ml) of Comparative Examples 1 and 2 is 3 While the average of the times is 49.8 and 64.8, in the present invention, the density (g / 200 ml) is preferably 70 or more barley tea particles, more preferably 75 or more. It is clear that the difference) is based on the fact that it is good.

  As for the taste of the drained barley tea beverage of Example 1, the average value of each of the three groups is 2.4, 3.3, and 2.4, and the average value of the entire group is 2.7. Similarly, the average value of the entire three groups of tastes of Comparative Example 1 is 2.2, and that of Comparative Example 2 is 1.7.

  Speaking of the taste of barley tea beverage, the value of 2.7 in Example 1 immediately after shaking 50 times is close to 3, which is an intermediate taste between 5 and 1, and it is not an authentic taste of barley tea, but can be drunk. After a few minutes, the barley tea of the example has a full-fledged taste that is quite close to boiled barley tea. However, the comparative examples are 2.2 and 1.7. Therefore, the thing of a comparative example is felt that a color and a taste are too thin as a barley tea drink, and it has shown that it is unsuitable as a barley tea drink in the short time of water discharge for about several dozen seconds-several minutes. In addition, the difference of these examples and comparative examples in the taste of barley tea beverages is the same as in the case of the color of the barley tea beverages. At the same time, it is clear that both particle size distribution differences or both density differences are influencing.

  That is, the flavor of the barley tea beverage of Example 1 was clearly evaluated for its superiority over the comparative example, coupled with the color evaluation of 3.8, and 93 wt% of barley tea with particles of 10 mesh or less was used. In spite of this, the taste and taste of the taste were not pointed out, and it became clear that it was almost a full-fledged barley tea flavor.

The present invention uses room temperature water as it is as watering barley tea that can bring out the color and taste of full-fledged barley tea in a short time without letting you feel when you drink, for example, to a tea bag The storage form can be effectively used industrially.
