Description

The present invention as well as rich in anthocyanidins as an active ingredient of the black bean, but about the black bean tea with germination activity.

  Green tea, which has been popular in the past, has been produced using evergreen leaves as its raw material. In Japan, Shizuoka, Uji in Kyoto, and Sayama in Saitama are the main tea leaf producers. Chinese tea is available for drinking. In addition to the above, cereal tea or mixed health tea made from various cereals has been favored by many people, and many types of products are commercially available.

  Grain tea refers to tea made from barley, wheat, bare wheat, rye, oats, pigeons, soybeans, black beans, and many other grains. It refers to mixed teas that are mixed with medicinal herbs such as leaves, rooibos, horsetail, green tea and oolong tea. In particular, in the case of tea made from cereals, if the cereals have the highest germination activity with the nutrients on the verge of germination, the tea contains abundant gaba (γ-aminobutyric acid) useful to the human body. be able to. Furthermore, recently, abundant nutrients of black grains such as black beans and black sesame seeds, especially anthocyanidins, which are active ingredients of black beans, have attracted attention.

  Taking barley tea as an example of cereal tea, the general production method is that barley as a raw material is carefully selected and then roasted and cooled, and then finished as a product by a packaging finishing process. Furthermore, sports drinks are often used to replenish water and salt after general sports, but even in the case of barley tea, there is also a method for producing salted barley tea by spraying salt water during the cooling step for the purpose of replenishing salt. Are known.

Japanese Patent No. 3368885

  Focusing on black bean tea among the above cereal teas, as described in Patent Document 1, conventionally, it is fried as it is, or it is dried and roasted after it is swollen by immersing black beans in water with the epidermis attached. , Manufactures tea leaves with forced cooling. Moreover, in order to set it as the state which has germination activity, it is indispensable to be immersed in water and to be in a germination state.

  However, since anthocyanidins, which are the active ingredients of black beans, are water-soluble, when they are immersed in water to make them germinate, many of them dissolve in water and flow out, and the resulting black bean tea The present inventors have found that only a small amount of anthocyanidin remains and the color of the extracted tea becomes light. However, if it is not immersed in water in order to prevent the outflow of anthocyanidins, it cannot be in a state having germination activity. Therefore, black bean tea that satisfies both germination activity and abundant anthocyanidins has not been provided yet.

  Furthermore, the conventional grain tea including black bean tea does not contain natural trace elements (minerals) required by the human body, and there is a problem that a satisfactory drink for health drinks is not necessarily obtained. In particular, the importance of trace elements existing in nature has recently been reviewed.

  On the other hand, seawater contains a lot of trace elements and is excellent as a salt to be added to beverages and other foods. However, in the present age when marine pollution has advanced, surface water in seawater cannot be added as it is.

Therefore, the present invention solves the problems of conventional black bean tea, contains a large amount of anthocyanidin, which is an active ingredient of black beans, and has a germination activity in which black beans have the highest nutrient content before germination. Black beans tea that is abundant in useful GABA (γ-aminobutyric acid) and that is effective as a health drink by effectively utilizing the mineral components contained in deep ocean water and reproducing the mineral balance of the deep ocean water The purpose is to obtain.

For the present invention to achieve the above object, indeed separated from the epidermis and polished to the extent that the black bean germ portions remaining, then roasted from a state with a dip to germinate active in water after separating the skin A black bean tea is provided based on black bean tea and an anthocyanidin abundantly contained in the black bean skin. In addition, after separating the epidermis into a state of having germination activity after separating the epidermis as black bean seeds , it is poured into cold water to stop germination and then roasted black bean seeds or epidermis are separated. After that, it is immersed in water for a predetermined time so as to have germination activity, and the black bean fruit subjected to the cold water charging process, steaming steaming process, drying process, roasting process, and cooling process is used.

The yield of black beans is about 80% or more . Also, roast the black bean skin. Furthermore, using a desalted water ocean deep water as a water soaking the fruit of black beans, as a water soaking the fruit of black beans, deep seawater raw, concentrated water of deep seawater, deep seawater of bittern Any one or a plurality are mixed and used.

According to the black bean tea obtained by the present invention, the black bean epidermis is not soaked in water, so that the anthocyanidin contained in the black bean epidermis is not dissolved in the water and does not flow out. In fact, black soybean tea rich in GABA (γ-aminobutyric acid) useful for the human body can be obtained by the highest level of nutrients on the verge of germination. Therefore, black bean tea that simultaneously satisfies germination activity and abundant anthocyanidins can be obtained.

Furthermore, by using the deep seawater demineralized water as the water to immerse the black bean seeds , it is possible to produce products using demineralized water, which is a natural material with high cleanliness obtained from the deep seawater, The added value can be increased. Further, the water soaking the fruit of black beans, raw water deep sea water, concentrated water of deep seawater, by mixing one or more of the bittern of deep ocean water, various nutrients and minerals such as trace elements Many of the ingredients are replenished, and even without using food additives or seasonings, the mineral balance of deep ocean water can be reproduced, and dark brown tea can be obtained. In particular, the natural salt in the sea water contains many trace elements as an essential salt in the human body, Ru suitable der also as a health drink.

The best embodiment of black bean tea according to the present invention will be described below. Anthocyanidin, which is a nutrient component of black beans, is contained in a large amount in the epidermis of black beans. On the other hand, in order to have germination activity, the black bean epidermis is not necessary, and the black beans with germs may be immersed in water. Therefore, the present invention is that the black beans are whitened to such an extent that the germ part remains and separated from the epidermis, and only the part of the black beans that separated the epidermis from the black beans is immersed in water, while the separated black beans If the portion of the skin is not soaked in water, the elution of anthocyanidins into water can be prevented, and a black bean skin containing abundant anthocyanidins can be obtained. Accordingly, the present invention is indeed separated from the epidermis and polished to the extent that the remaining germ part black beans, and fruit of black beans roasted from a state with a dip to germinate active in water after separation of the epidermis, the real The basic means is black bean tea , which contains a black bean skin that is not soaked in water after being separated, and contains anthocyanidins abundantly contained in the black bean skin as a tea component .

  FIG. 1 is a flowchart showing an example of a manufacturing process of black bean tea according to the present embodiment. First, black beans selected as a raw material in Step 1 are prepared, black beans are refined in Step 2, and a black bean skin and black bean fruits are prepared. And to separate. The whitening is performed to such an extent that a germ portion necessary for germination of black beans remains. Specifically, the yield of the whitening degree is about 80% or more. In parallel with the above steps, in step 3, deep sea water taken from the deep sea 200 meters or less below sea level is prepared. In step 4, the deep sea water is filtered, and in step 5, ion exchange method, reverse osmosis membrane. Demineralized water is obtained by desalting by the method or electrolysis.

In step 6, the black bean skin obtained by the whitening in step 2 is collected and roasted (fired) in step 7 so as not to be immersed in water . The firing condition is about 200 ° C. for 16 minutes. In the examples, roasting was performed using a herb roaster. The black bean skin can be used as it is without roasting. In addition, a black bean skin that has been subjected to any of roasting, drying, sterilization, pulverization, or a plurality of treatments can also be used. Furthermore, in the present invention, a black bean skin separated from black beans or a black bean skin separated from black beans and roasted separately from black beans is added to other cereal teas, mixed health teas and other teas without using black beans. Can also be made into products.

  In step 8, the black bean fruits obtained by the whitening in step 2 are collected and immersed in a suitable amount of water in step 9, so that the black bean fruits are brought into an activated state immediately before germination, that is, a state having germination activity. It is appropriate that the immersion time until the black bean seeds have germination activity is 24 hours ± 1 hour in which the GABA does not decrease, and the water temperature is about 28 ° C. As the water used for the immersion in Step 9, the demineralized water obtained in Step 5 is used. In addition, the water to be used is not necessarily limited to the demineralized water of deep ocean water, and any one or a plurality of water such as demineralized water, mineral spring water, well water, spring water, tap water, etc. may be used. . Further, these waters may be used by mixing any one or more of raw water of deep ocean water, concentrated water of deep ocean water, and deep water of ocean water.

  The reason why black beans are soaked in the demineralized water of deep ocean water is that the demineralized water from deep ocean water is extremely clean and the permeability of the demineralized water to black beans is high. This is because the germination activity can be achieved earlier than when it is used. Tap water requires treatment with chlorination or other chemicals to sterilize bacteria and prevent growth. However, in the case of using demineralized water from deep ocean water, the use of chemicals is not necessary in principle. This makes it possible to take advantage of the absence of water contamination by chemical substances.

  As a cold water charging step of Step 10, black bean fruit having germination activity is charged into cold water. The reason for putting black bean into cold water is to stop germination and prevent a decrease in GABA (γ-aminobutyric acid). In addition, by using any one of the deep seawater demineralized water, the deep seawater raw water, and the deep seawater concentrated water as the cold water in the cold water charging process, the cleanliness of the same as the above-mentioned black bean seed immersion water is achieved. Products can be manufactured using high natural materials such as demineralized water of deep ocean water, and the added value can be increased. Furthermore, as cold water in the cold water injection process, deep seawater demineralized water, mineral spring water, well water, spring water, tap water, etc., or any of a plurality of clean water, raw deep sea water, concentrated deep sea water , Any one or more of deep sea water bites can be mixed and used.

  Next, in step 11, a steaming process is performed in which the beans are steamed. Steaming time is about 30 minutes. After performing the cooling process in step 12, the drying process is performed in step 13, the moisture is reduced by evaporation, and then the roasting process is performed in step 14. The roasting conditions are about 200 ° C. and 6 minutes. In the examples, a grain roasting machine was used. Further, after performing a cooling process in step 15, a bag removing process is performed in step 16.

  The cooling process of step 15 is that there is a possibility that black beans will ignite when the raw material is taken out from the kettle after roasting. For the main purpose of preventing this ignition, water is sprayed on the raw material after roasting. It is a process. In the present invention, in order to replenish the salt and minerals, the dried black bean fruit is roasted at 200 ° C. using demineralized water of deep ocean water without using tap water or the like in the cooling process of step 15. After cooling, it can be cooled to finish with salted black bean tea. In addition, as the cold water in the cooling process, raw water of deep ocean water, concentrated water of deep ocean water, or demineralized water, mineral spring water, well water, spring water, tap water, etc. It is also possible to use water obtained by mixing any one or more of the raw water of deep ocean water, the concentrated water of deep ocean water, or the bittern of deep ocean water.

  Next, the black beans obtained in the bag removing process are put into and mixed with the black bean skin that has been roasted in step 7, the cooling process is performed in step 17, and the cracking process is performed in which fine cutting is performed in step 18. . In addition, it is also possible to produce a product in a bean state without performing split processing. Next, weigh in step 19 and pack a certain amount in a tea pack in step 20, pack in a cosmetic bag in step 21 and then inspect the weight with a weight checker in step 22 to make a product, and pack cardboard in step 23 For shipping.

  Here, the GABA will be described. This GABA (γ-aminobutyric acid) is a non-protein amino acid and is produced by decarboxylation of glutamic acid by the action of glutamic acid decarboxylase (GAD) widely distributed in microorganisms. Gabba is an inhibitory transmitter of nerves in higher animals and is known to have a blood pressure lowering action and a diuretic action. In foods, Gabba contained in red koji and Gabaron tea has a significant blood pressure lowering action. It has been made clear.

  GABA is present in many animals and plants, and GAD is present in microorganisms, so it is naturally included in foods made from these. As a result of examining the GABA content in various foods, it is abundant in alcoholic beverages such as yogurt, sake, wine, beer, vinegar, pickles, kimchi, vegetable juice, and cereals.

  Next, anthocyanidin (colorimetric method as delphinidin), black bean anthocyanidin (leucoanthocyanidin colorimetric method), γ-aminobutyric acid (100 g) contained in 100 g for each of the examples according to the present invention, comparative examples and conventional examples Table 1 shows the results of measuring the gap. In an embodiment according to the present invention, black beans and epidermis are separated at a whitening degree of 80% or more, and only black beans are sent to the air for 25 hours while being air-delivered, steamed, dried, roasted After performing the roasting process and the cooling process, black bean tea was produced by mixing the black beans with the skin of the black beans that had been roasted without being immersed in water. In the comparative example, black beans are not processed as raw raw materials of round grains, and in the conventional example, the raw material of black beans is immersed in water for 17 hours without separating the skin from the black beans, Black bean tea that has been dried, roasted and cooled.

  As described in Table 1, anthocyanidin in 100 g of Comparative Example was 140 mg, γ-aminobutyric acid was 9 mg, anthocyanidin in 100 g of Conventional Example was 20 mg, black bean anthocyanidin was 15.6 mg, and γ-aminobutyric acid was 53 mg. is there. Therefore, it can be seen that the anthocyanidins are eluted and reduced by immersing the raw black beans in water. On the other hand, in the Example which concerns on this invention, the anthocyanidin in 100g increased significantly with 160 mg, black bean anthocyanidin with 110 mg, and (gamma) -aminobutyric acid was 35 mg. Therefore, according to the present invention, black bean tea that simultaneously satisfies germination activity and abundant anthocyanidins can be provided.

  Next, the deep sea water used in the present invention as black bean soak and cold water is described. Recently, the cleanliness and abundant mineral components of the deep sea water have attracted the attention of consumers and called the boom. The water that has been desalted from deep ocean water has entered the field of drinking water. The above-mentioned deep ocean waters are currently practically taken in places around the world, such as “Norway offshore”, “Hawaii offshore”, “Kochi Murotomisaki off Kochi Prefecture”, and other places, and wind waves and surface temperatures usually found on the ocean surface Seawater in an environment that does not cause convection and mixing due to changes, and is not affected by marine pollution caused by various oils, chemical substances, agricultural chemicals and other harmful substances used on the ground. There is very little dissolved organic matter in it, and it is characterized by being extremely clean from a microbial point of view. The water temperature is as low as 13 ° C. or less on average per year, and contains many natural elements required by the human body.

  The deep ocean water used in the above example is seawater taken from a point of 320 meters off the coast of Cape Muroto, and among the tristate nitrogen contained in the deep water, ammonia nitrogen and nitrite nitrogen are negligible. There is little impact on organisms, and nitrate nitrogen was also very small in the surface layer, but as the water depth increased, the concentration increased, and more than 95% of the inorganic dissolved nitrogen in water at a depth of 200 meters or less was nitrate. 24 μM is present in nitrogen. In addition, 1.7 μM phosphoric acid phosphorus and 41 μM silicic acid silicon are dissolved, and each has a nutrient concentration of 5 to 10 times or more of the surface layer portion.

  Natural elements essential for the growth of living organisms contained in deep sea water are Fe (iron), I (iodine), Cu (copper), Mn (manganese), Zn (zinc), Co (cobalt), 15 elements of Mo (molybdenum), Se (selenium), Cr (chromium), Sn (tin), V (vanadium), F (fluorine), Si (silicon), Ni (nickel), As (arsenic), A major feature is that these elements are all contained in the deep ocean water in a well-balanced manner. Therefore, it can be said that deep sea water has great potential for the growth and growth of marine organisms. Such potential has been proved because it has been used in aquaculture experiments such as medals, kombu, and deep-sea corals in recent years. In particular, it has been reported that the deep sea water off Norway is called fjord deep water and is suitable for salmon farming.

  The number of viable bacteria in the deep ocean water is one order of magnitude or more less than that in the surface water, and since there are few pathogenic organisms, there is absolutely no concern about diseases caused by fish pathogens derived from seawater. There is also a great feature that it is extremely safe when used in black bean tea. The same applies to demineralized water. The present invention provides a beverage having characteristics that cannot be realized by various conventional cereal teas by promoting the growth of a living body by incorporating natural elements contained in such deep ocean water into black bean tea. Can do.

As described above, according to the present invention, anthocyanidins contained in a large amount of black bean epidermis do not dissolve and flow out into water, and black beans are useful for the human body because the nutrients on the verge of germination are at the highest level. Black bean tea containing abundant gaba (γ-aminobutyric acid) can be obtained. In addition, the use of deep seawater demineralized water as the water to immerse the black bean seeds , so that many of the mineral components such as various nutrients and trace elements are replenished, and black bean tea that reproduces the mineral balance of deep sea water can get. In addition, it is also possible to use a method in which after the separated black bean skin is fired, it is added to tea or other products made from other grains. For example, “Black Bean Skin + Black Bean + Barley”, “Black Bean Skin + Barley”, “Black Bean Skin + Other Grain Tea”, and the like are conceivable.

The flowchart which shows the example of a manufacturing process of the black bean tea concerning this embodiment.
