Description

[Technical field]

[0001] The present invention relates to a soup stock pack used for making soup stock for miso soup, simmered dishes, etc. [Background technology]

[0002] In recent years, a method for isolating ferritin with high absorption rate has been established. Ferritin is the form in which iron is stored in the body, and since iron is surrounded by proteins, it does not generate free radicals and is said to have a high absorption rate but a low risk of side effects (see, for example, Patent Document 1).

[0003] Ferritin comes as a powder and is typically taken orally as a supplement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5896543 Summary of the Invention [Problem to be solved by the invention]

[0005] However, many people find it difficult to orally administer ferritin in powder form. In addition, oral administration of ferritin as a supplement or drug involves ingesting high concentrations of iron, which can lead to side effects. For this reason, there has been a demand for a method to easily and naturally ingest ferritin with food.

[0006] The present invention has been made to solve such problems, and its object is to provide a soup stock pack that allows ferritin to be easily ingested along with a meal. [Means for solving the problem]

[0007] In order to solve such problems, the dashi pack of the present invention is characterized by having ferritin powder, dashi ingredients, and a pack packaging material that contains the ferritin and the dashi ingredients and is water-permeable. Effect of the Invention

[0008] According to the present invention, a dashi pack can be realized that allows ferritin to be easily ingested along with a meal. [Brief description of the drawings]

[0009] [Figure 1] Graph (1) showing the results of a questionnaire survey in an embodiment. [Diagram 2] Graph (2) showing the results of the questionnaire survey in the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Next, an embodiment of the present invention will be described.

[0011] The present invention comprises ferritin powder, a soup stock ingredient, and a packaging material containing the ferritin and the soup stock ingredient.

[0012] The dashi ingredients are a mixture of one or more ingredients. There is no limitation on the ingredients, and known ingredients can be appropriately selected and used. For example, the ingredients include dried bonito, rough dried bonito, dried bonito flakes, dried bonito flakes, dried mackerel, dried tuna, dried horse mackerel, dried sardines, dried pacific saury, dried salmon, dried round tuna, dried round tuna, dried horse mackerel, dried mackerel, dried mackerel, dried horse ... , Katakuchi Niboshi, Setouchi Niboshi, Horse Mackerel Niboshi, Kibinago Niboshi, Nodoguro Niboshi, Yakiago, Naked Muro, Hidaka Konbu, Rishiri Konbu, True Konbu, Rausu Konbu, Cat's Foot Konbu, Long Head Konbu, True Konbu Ear, Rausu Konbu Ear, Rishiri Konbu Ear, Shiitake Mushroom, Shiitake Mushroom Broken, Shiitake Mushroom Stem, Donko, Koshin, Dried Squid, Peeled Shrimp, Chicken Flakes, etc. In addition, shellfish such as scallops, dried clams, and corbiculas, and vegetables such as onions, garlic, and carrots can also be used as ingredients. In addition, various seasonings for adjusting the taste of the soup stock, such as salt, pepper, protein hydrolyzates, amino acids, and sake lees, as well as functional ingredients and additives with different functions, such as protein, calcium, and dextrin, can also be used as ingredients.

[0013] The shape of the dashi ingredients is not specified, and they may be in their original form, cut, crushed and roughly crushed, or powdered, or a mixture of these. Powder means an average particle size of 0.2 mm or less, and roughly crushed means a size of more than 0.2 mm to 2 mm or more. It is preferable to make all the dashi ingredients in powder form, since they can be used as toppings. Generally, dried dashi ingredients are often used, but this is not limited to this.

[0014] The packing material is made of a material that is permeable to water and can maintain its shape when immersed in hot water. For example, paper or nonwoven fabric made of plant fiber, wood fiber, plastic, or a mixture of these is preferably used. When the dashi pack is placed in hot water and shaken for 5 minutes, the fiber gaps are capable of releasing 20% ​​or more, or even 40% or more of the ferritin powder contained therein, and it is preferable that the amount of the dashi ingredients released at this time is less than 10% by weight. It is also possible to form small holes on the surface of the packing material. Of course, holes may be made in the surface of a plastic sheet to allow water to be immersed.

[0015] When using pulp material (natural cellulose fiber) as the main raw material, a heat pack type that is hot and water resistant and contains plastic fiber is preferred, with an average basis weight of 15 to 26 g / m2, and more preferably 17 to 23 g / m2, being suitably used.

[0016] If the average basis weight is too small, the strength will be insufficient and it may break during storage or immersion in water, which is not preferable. On the other hand, if the average basis weight is too large, the gaps between the fibers will be small, which will result in poor extraction of the soup stock components and ferritin components, which is also not preferable. Note that the main raw material refers to a material that accounts for 50% or more (by weight) of the fibers used.

[0017] Ferritin is an intracellular protein-iron complex that is made by self-assembly of subunits. This protein cage can reversibly organize iron into the caged biomineral Fe2O3·H2O in plants, animals, and bacteria. The iron oxybiomineral in this protein nanocage is an iron concentrate for protein synthesis and a trap for Fe(II) / oxygen / peroxide for antioxidant protection (Fenton chemistry reactants). The iron sequestered in ferritin is concentrated 100 billion times above the solubility of the non-toxic, usable form of iron(II) ion. The four-α-helical bundle that is the subunit of the ferritin protein contains the catalytic center that converts two Fe(II) atoms into an Fe(III)-oxo-bridged dimer intermediate in mineralization. The two types of ferritins are i) maxiferritins, found in animals, plants, and bacteria, which are 24 polypeptide, four-bundle subunit assemblies, and ii) miniferritins (also called Dps proteins), found in archaea and bacteria, which are 12 polypeptide, four-bundle subunit assemblies.

[0018] In animals, ferritin is expressed in tissues, specifically in the erythroid system of the liver, kidney, spleen, and bone marrow. It is found mainly in cells and acts as a reserve of iron for the production of hemoglobin. A small portion is present in serum and contributes little to the total iron stores, but Ferritin is clinically used as a reporter of iron levels in the blood. Approximately 25 distinct subtypes are identified, depending on the proportion of the major subtypes, H or L. These distinct subtypes occur in animals as sexually active organisms. They differ in terms of distribution, rate and mechanism of iron oxidation, core formation, and physiological iron turnover.

[0019] Ferritin from plants and animals is used as a food source for humans and other animals. Ferritin can survive digestion for the most part and is absorbed into the body. More iron per molecule than any other dietary iron source or iron supplement Ferritin is also efficiently absorbed by the intestine. Ferritin also survives high heat treatment. The ferritin protein makes ferritin a naturally enteric-coated, slow-acting, and efficiently absorbed source of iron. Ferritin is therefore a key component in animals with dietary iron requirements. It can be used to supplement iron in the diet.

[0020] Currently, it is possible to administer to a subject an amount sufficient to treat an iron deficiency disorder or prevent iron deficiency. Methods for isolating plant and animal ferritins from low-cost, readily available sources There is a need for a method to determine the amount of iron derived from plant and animal ferritin. There is a need for a method for doing so.

[0021] Ferritin is not particularly limited, but it is possible to obtain ferritin powder containing ferritin at high concentrations by enzymatically treating insoluble matter of plant raw materials such as seeds, beans, stems, fruits, leaves, and roots, followed by fractionation and concentration.

[0022] The iron content of ferritin powder is said to be 5-15%. The daily iron intake recommended by the Ministry of Health, Labor and Welfare is 10.5-11.0 mg for women aged 15-69, with the tolerable upper limit being 35-45 mg. This is calculated assuming that the absorption rate of iron in food is 15% (https: / / www.mhlw.go.jp / file / 05-Shingikai-10901000-Kenkoukyoku-Soumuka / 0000042638.pdf).

[0023] While insufficient intake of iron can cause anemia, excessive intake of iron can put a strain on the liver and aggravate hepatitis. Iron is also found in meat, fish, eggs, vegetables, etc., and iron can be consumed through normal meals. Therefore, it is preferable that the amount of iron consumed from a dashi pack is 10 to 45% (1.05 mg to 4.95 mg) of the recommended amount, or even 15 to 40% (1.575 mg to 4.4 mg).

[0024] Generally, 2 to 10 g of dashi ingredients are used for one serving of dashi in a dashi pack. Therefore, the weight ratio (dry weight) is preferably 10.5 mg to 247.5 mg, and more preferably 15.75 mg to 220 mg, per 100 g of dashi ingredients.

[0025] There is no restriction on the ratio of ferritin powder to the dashi ingredients in the dashi pack, and it is selected appropriately depending on the contents of the dashi ingredients. However, it is preferable that the ratio be within the range of 1 to 10 per 100 dashi ingredients in terms of weight ratio (dry weight), so as to add a certain amount of iron components without impairing the flavor of the dashi.

[0026] The ferritin powder preferably has a 30 mesh pass of 80% or more, and more preferably a 40 mesh pass of 80% or more. More preferably, it has a 40 mesh pass of 90% or more. This is to facilitate release from the packaging material. By incorporating ferritin powder in a bag-shaped soup stock pack, the ferritin suspended in water is released into the soup stock, and it is presumed that the absorption rate into the body can be significantly improved compared to when the ferritin powder is orally ingested as it is.

[0027] The dashi pack may be produced by mixing the dashi ingredients and ferritin powder in a predetermined ratio and then packing the mixture in a predetermined amount in a packaging material, or by blending predetermined amounts of the dashi ingredients and ferritin powder into a packaging material.

[0028] The manufactured dashi pack is immersed in hot or cold water to extract the dashi ingredients and ferritin. The pack material is preferably paper, which does not leak the dashi ingredients contained in the pack under normal circumstances, but when immersed in hot or cold water, the hydrogen bonds between the fibers are loosened and the gaps between the fibers are enlarged, making it easier to extract the dashi ingredients and ferritin from the pack material. EXAMPLES

[0029] The present invention will be described in more detail with reference to examples, although the present invention is not limited to these examples.

[0030] A dashi pack was prepared by adding 55 mg of ferritin powder (2.75 mg of iron) to powdered dashi ingredients (8 g). The pack packaging material used was unbleached Heat Pack UBA (manufactured by Nippon Paper Papylia Co., Ltd., with a basis weight of 22 g / m2. The dashi ingredients were 7.95 g, and 692 mg of ferritin powder was mixed for every 100 g of dashi ingredients.

[0031] The ferritin iron powder used was Mame-Tetsu (registered trademark) SloIron (registered trademark) (sold by Anti-Aging Pro Co., Ltd.), with a powder particle size of 40 mesh 98% pass (JIS analytical sieve), moisture content of 8% or less (normal pressure heating weight loss method), iron content of 5% or more (ICP-OES), and ferritin iron content of around 10% (protein immunoblot quantification method).

[0032] The monitors were asked to eat food made with one dashi packet every day for 10 days, after which they filled out a questionnaire.

[0033] The number of respondents to the survey was 18, the gender was female, and the age distribution was 3 in their late 20s, 10 in their early 30s, and 5 in their late 30s.

[0034] In response to the question, "Did you notice any changes or effects as a result of using the dashi pack?", 16 people (88.9%) answered that they had noticed some changes, while 2 people (11.1%) answered that they had not noticed any changes.

[0035] The question was "Please select all that showed even the slightest change or effect due to iron (multiple selections possible)," and the responses to the following options are shown in the graph in Figure 1. anemia Tired easily Irritation Drowsiness Headaches and stiff shoulders Hair and skin problems Bear Sagging

[0036] The graph in Figure 2 shows the answers to the question, "At what time of day did you feel the most effect of iron stock? (Multiple choices possible)" and the options below. Immediately after tasting 30 minutes to 1 hour after tasting 1 to 3 hours after tasting 3 to 9 hours after tasting next morning Gradually throughout the day After a few days, gradually After 10 days of tasting,

[0037] The question was, "Did you experience any stomach pains or nausea after tasting the iron dashi? (Due to the composition of the ingredients, there should be no free radical effects, but if you did, please answer honestly.)" and the following options were given: No problem. I had a stomach ache I felt irritated. Other physical ailments As a result, 17 people answered that there were no problems, and one person selected "I had other health problems," saying, "I only had diarrhea at first, but then recovered."

[0038] Thus, despite the extremely small amount of iron (2.75mg) in the ferritin powder, 16 out of 18 people were able to feel the effects. The iron preparation commonly used to treat anemia, sodium ferrous citrate, is poorly absorbed, so it is recommended that 100-200mg of iron be administered per day. This suggests that ingesting suspended ferritin improves the absorption rate into the body.

[0039] <Actions and Effects> The following describes the features of the inventions extracted from the above-described embodiments, showing their effects as necessary. In the following, for ease of understanding, the corresponding configurations in the above-described embodiments are appropriately shown in parentheses, but the specific configurations shown in parentheses are not limited to these. In addition, the meanings and examples of terms described in each feature may be applied as the meanings and examples of terms described in other features described in the same wording.

[0040] In the above configuration, the dashi pack of the present invention is characterized by having ferritin powder, dashi ingredients, and a pack packaging material that contains the ferritin and the dashi ingredients and is water-permeable.

[0041] This allows ferritin to be released from the pack in a suspended state in soup stock, making it easy to take ferritin powder orally. Ingesting ferritin in a suspended state is also expected to improve the absorption rate into the body.

[0042] In the soup stock pack of the present invention, the particle size of the ferritin powder is It is characterized by a ratio of 30 mesh passes of 80% or more.

[0043] This makes it easier to release the ferritin from the packaging material.

[0044] In the soup stock pack of the present invention, the particle size of the ferritin powder is characterized in that the ratio of 30 mesh pass particles is 80% or more.

[0045] This makes it easier to release the ferritin powder from the gaps between the fibers of the packing material in water.

[0046] In the soup stock pack of the present invention, the particle size of the ferritin powder is characterized in that the ratio of 40 mesh pass particles is 80% or more.

[0047] This makes it easier to release the ferritin powder from the gaps between the fibers of the packing material in water.

[0048] The soup stock pack of the present invention is characterized in that the weight of iron in the ferritin powder is 1.05 mg or more.

[0049] This means that you can get about 10% of the Ministry of Health, Labour and Welfare's recommended iron intake from just one pack.

[0050] In the soup stock pack of the present invention, the soup stock ingredients are in powder form. It is characterized by:

[0051] This allows the soup stock components to be released quickly, and also traps the ferritin powder, which has a small particle size in a dry state, making it less likely to leak from the packaging material.

[0052] In the soup stock pack of the present invention, the particle size of the soup stock ingredients is: It is characterized by being larger than the ferritin powder.

[0053] As a result, the soup stock ingredients are not released outside the pack packaging material, and only the dissolved soup stock components are released, while the ferritin powder can be released in a suspended state.

[0054] In the soup stock pack of the present invention, the pack packaging material is It is characterized by its main raw material being natural cellulose fiber.

[0055] This allows the gaps between the fibers to expand in response to swelling with water, minimizing leakage of the encapsulated soup stock ingredients and ferritin powder when in a dry state, and making it easier to release the ferritin powder when in a wet state.

[0056] In the soup stock pack of the present invention, the pack packaging material is: It is characterized by a basis weight of 15 to 26 g / m2.

[0057] This allows the dry and wet strength and fiber spacing to be appropriately set. [Industrial Applicability]
