JP4759337B2 - Plant mineral extract and method for producing the same - Google Patents

Description

  The present invention relates to an extract of a plant mineral obtained by heat-treating a plant, that is, a plant or seaweed on land, and a method for producing the same.

  It is well known that various minerals are essential nutrients for living activities of organisms, and the intake of mineral groups to the human body is mostly performed through food. There are over 100 types of elements on the earth, and the distribution of elements in the earth, plants, and human bodies, excluding the four major elements of hydrogen, oxygen, carbon and nitrogen, which account for about 95% of all of them. Things are inorganic, ie minerals. The distribution of mineral groups in the earth, plants, and human body is as shown in Table 1. Plants and human bodies are mostly calcium, potassium, phosphorus, magnesium, sodium, chlorine, sulfur, etc. The earth is overwhelmingly rich in silicon and aminium, showing a completely different distribution from plants and human bodies.

  Since minerals cannot be produced in the human body, it is necessary to take as much balance as necessary from foods made of animals and plants. However, as shown in Table 2, mineral distribution is greatly different between plants grown by humans such as cereals such as rice and wheat, and crops such as vegetables and fruits. Therefore, eating only artificially cultivated crops is not preferable because the balance of minerals that can be ingested by the human body is lost. However, it is practically difficult to take enough wild plants in the normal diet.

  Therefore, conventionally, minerals have been replenished by extracting minerals from soil, rocks, sand, seawater, groundwater, etc., or burning animals and plants to carbonize and ash to extract minerals. ing. For example, it contains one or more mineral components selected from the group consisting of ash derived from tofu production mash, ash derived from trees and ash derived from moroheia leaves, and a mineral component of seaweed extract A plant mineral composition is known (see Patent Document 1). According to Patent Document 1, the ash derived from the tofu production mash is heated at a temperature of 400 to 1800 ° C., preferably 900 ° C. for 1 to 8 hours using an incinerator, so that the ash derived from the tree is By heating the tree at a temperature of 400 to 2500 ° C., preferably 900 to 1000 ° C. for 1 to 8 hours in accordance with a conventional method of charcoal production, the ash content of the morohea leaf is converted to a morohea leaf at a temperature of 400 to 2500 using an electric furnace or the like. It is obtained by ashing by heating at ℃, preferably at 800 ℃ for 1 to 8 hours.

  In addition, considering the use of ash produced when plants are used as fuel as an extraction material, plant-derived leaf, stem, and root baked ash is used at room temperature to an aqueous solution using an acidic aqueous solution, a neutral aqueous solution, or an alkaline aqueous solution. An extract composition obtained by extraction at 80 ° C. and an extract dry composition obtained by drying the extract composition are known (see, for example, Patent Document 2). Further, plant mineral salts containing various useful mineral salts derived from plants are known by ashing plants with a high ash content and extracting them with seawater and / or seawater-derived aqueous solvents. (For example, see Patent Document 3). According to Patent Document 3, the ashing conditions of the raw material plant are good at 800 to 900 ° C. for 3 to 4 hours, the extraction temperature is good at room temperature to 40 ° C., the seawater extract is filtered and reduced in pressure. Concentrate, then boil the concentrate in an evaporating kettle to precipitate the desired plant mineral salt.

  On the other hand, the inventor of the present application has announced that water-soluble inorganic minerals extracted from living organisms such as seaweed, wild grass, and tree leaves, which have grown naturally, have a useful effect on human health since around 1996 (for example, (Refer nonpatent literature 1). Furthermore, a method has been proposed in which an organism containing minerals is heat-treated, and minerals are extracted and collected from the carbonized and / or incinerated products (see Patent Document 4). More specifically, by heating at the heating upper limit temperature of the mineral contained in the raw material organism, the organic component can be removed and the specific mineral to be collected can be reliably extracted and collected. As a result, a biomineral having good absorbability to the human body and safe and having a relatively stable mineral balance can be obtained.

  Further, the inventor of the present application has developed treatment agents for foods and the like containing biologically derived water-soluble minerals extracted from ash products such as seaweeds, wild grasses, and tree leaves (see, for example, Patent Document 5). According to Patent Document 5, raw materials containing various mineral components such as seaweeds, pine needles, loquat leaves and other plants, swordfish, crab shells, etc. are heated at a temperature of 500-2000 ° C. Biominerals are extracted using a finely pulverized product of about ~ 500 mesh.

  Furthermore, the present inventor has announced that this biological mineral is not only useful for human health but also effective for maintaining the freshness of foods and preventing oxidation (for example, see Non-Patent Document 2). As a result of various studies and considerations regarding the relationship between the oxidation-reduction potential of food and the health of the human body, it was confirmed that the reducing power that prevents oxidation plays a major role as the reason for producing such an effective action. A method has been developed that can accurately determine the quality of a food by measuring the reducing power as a redox potential (see, for example, Patent Document 6). In this method, the oxidation-reduction potential is measured with the food in an aqueous solution, and corrected to the value of the standard hydrogen electrode. The corrected value is closer to −420 mV, and the food has a higher reducing power and is closer to +815 mV. It is determined that the food has a low reducing power and is bad.

  However, it has been found that the reducing power of the biological mineral obtained by the conventional method described above is not so high. That is, extracts obtained by simple carbonization or ashing of plants, and those obtained by re-extraction from these extracts using a solvent have a problem that high reducing power cannot be obtained.

  The inventor of the present application has a certain degree of reducing power, that is, a redox potential of about −50 to −100 mV, in the carbonized and incinerated products such as seaweed, wild grass, and tree leaves and their water-soluble inorganic extracts. The degree of freshness maintaining effect of various foods was tested. As a result, it was confirmed that a certain degree of freshness-preserving effect was exhibited, but this was effective only for limited foods, and it was not possible to obtain a freshness-maintaining effect that could be commercialized for many other foods. There wasn't. Depending on the type of plant, it may be possible to have a rarely high reducing power, but no such wild plant or cultivated plant exists in the vicinity of daily life.

  Furthermore, minerals contained in water-soluble mineral extracts obtained simply from carbonization or ashing of plants are oxidized over time. Therefore, a water-soluble inorganic extract that originally has a low reducing power has a problem that the initial reducing power is further reduced by oxidation. Conventionally, health foods such as alkaline ionized water, reduced water, and mineral water, which have been known to be reducible, have not exhibited the reducing power as indicated, as long as the inventors have investigated. This is considered to have been oxidized with the passage of time even if there was an initial reducing power.

  Therefore, the present invention has been made in view of the above-described conventional problems, and its purpose is to be safe for the human body, and when directly ingested, enhances the defense function against various lifestyle-related diseases, such as skin diseases. It is derived from a plant that exhibits high reducing power so that it can effectively improve the diseases of this product, and when used in foods, such as maintaining freshness, preventing oxidation, improving color development, and preventing discoloration To provide biominerals. Furthermore, the objective of this invention is providing the biological mineral derived from a plant which can maintain high reducing power for a long time. Another object of the present invention is to provide a method for producing such a biological mineral.

  The inventor of the present application has conducted various tests on the carbonized or incinerated extract of plants and the water-soluble inorganic extract therefrom, such as maintaining the freshness of food, improving reducing power, preventing oxidation, improving color development, and preventing discoloration. As a result, a plant carbonized or incinerated extract having a high reducing power with a redox potential of −200 mV or more and a water-soluble inorganic extract therefrom are found, and such high reducing power provides a practically sufficient food freshness-retaining effect and reduction. It was confirmed that effects such as improvement and maintenance of power, prevention of oxidation, improvement of color development, prevention of fading, and excellent taste were obtained.

  However, the conventional carbonization and / or ashing products obtained by heating at a temperature of about 1000 ° C. and extracts from them have a high reducing power regardless of whether they are a single plant or a mixture of multiple types of plants. It was not obtained. Therefore, the present inventor considered that the reducing power of the plant mineral extract obtained from the carbonization or ashing of the plant is related to the combustion temperature of the raw material plant, and the results of various tests and considerations The present invention has been devised.

According to the present invention, in order to achieve the above-mentioned object, the mineral extract contained in the two or more plants is extracted by heating and melting two or more plants at a temperature of 2000 ° C. or more . There is provided a plant mineral extract, wherein the extract has an oxidation-reduction potential of −200 mV or more .

  This plant mineral extract is not only safe for the human body by containing minerals, which are plant extracts derived from nature, but also desired by the source plant that unnecessary organic substances are sufficiently removed by melting the source plant. Therefore, it has a very high reducing power compared with the extract from the conventional plant. Therefore, the reducing power can be maintained over a long period of time.

In one embodiment, the oxidation-reduction potential is −200 mV or more, thereby enhancing the defense function against various lifestyle-related diseases for the human body and improving diseases such as skin diseases more effectively. when used in freshness retention, antioxidant, coloring improvement, Una O Ru are obtained effects such as anti-fading, remembering high reducing power, and can keep it a long time.

  In another embodiment, it contains many kinds of minerals including at least calcium, potassium, chlorine, sodium, sulfur, magnesium, phosphorus, silicon, and is particularly useful for maintaining the health of the human body.

  According to another aspect of the present invention, there is provided a method for producing a plant mineral extract that obtains an extract of minerals contained in a raw material plant by heating and melting one or more kinds of plants. .

  In this way, unnecessary organic substances are sufficiently removed by melting the raw material plant, so that the desired mineral contained in the raw material plant is contained in high purity, and has a very high reducing power as compared with the conventional one. Can be obtained over a long period of time.

  In an embodiment, a desired plant mineral extract can be obtained by melting two or more kinds of plants by heating them for each kind and blending those melts. In another embodiment, a desired plant mineral extract can be obtained in the same manner by heating and melting a mixture of two or more kinds of plants. In any case, by using a plurality of types of plants, different types of minerals contained in each plant can be contained, and even if one type of plant does not have sufficient reducing power, it is desirable depending on its formulation. Can have a high reducing power.

  In some embodiments, the redox potential of the extract is −200 mV or higher. A plant mineral extract having a high reducing power and capable of maintaining it for a long time can be obtained.

  In another embodiment, a plant mineral extract having a redox potential of −200 mV or more and capable of sustaining it for a long period of time is produced by heating and melting the raw material plant at a temperature of 2000 ° C. or higher. it can.

  In still another embodiment, the plant is heated at a temperature of 1000 ° C. or lower to be carbonized and / or incinerated, and then heated at a temperature of 2000 ° C. or higher to be melted. If the heat treatment is performed in two stages in this way, the bulk and weight of the raw material plant can be reduced in the first ashing / carbonization step, so that the next melting operation can be simplified and the heating equipment and equipment necessary for it. Can be configured relatively easily and compactly at a low price.

  Moreover, in another Example, the purity of the inorganic substance contained can be improved more by obtaining a liquid extract from the melt of a plant using water, plant vinegar, or an alcohol solution. In yet another embodiment, removing water from the resulting liquid extract and solidifying it to more effectively prevent oxidation and maintain a high reducing power over a longer period of time. Can do.

Below, the suitable Example of the plant mineral extract by this invention is described in detail.
First, one kind or two or more kinds of plants are heat-treated to be carbonized and / or incinerated. It is preferable that the raw material plant is sufficiently cleaned in advance, washed with water and dried. The said heat processing is performed at the temperature of the range of about 300-1000 degreeC according to the kind of raw material plant to be used. The obtained carbonized and / or incinerated product is further heated at a temperature of 2000 ° C. or higher to be melted into magma. Thereby, the plant mineral extract of the present invention is extracted. When using 2 or more types of raw material plants, the heat treatment mentioned above is performed for every kind of plant to be used, or what mixed them can be heat-processed.

  When the obtained melted material is one kind of raw material plant, the melted product itself must have a high reducing power of, for example, a redox potential of about −200 mV or more. When there are two or more kinds of raw material plants, a blend of those melted products, that is, a blended melt-treated product for each plant type or a melted product that has been mixed and heat-treated is similarly reduced in redox potential. Any material having a high reducing power of −200 mV or more may be used. Even if one kind of plant alone does not have a desired redox potential, a high reducing power can be obtained by preparing using a plurality of kinds of plants in this way.

  When the heat treatment is performed in two stages as described above, the bulk and weight of the raw plant can be reduced in the first carbonization / ashing process. Therefore, the next melting operation can be simplified, and the heating device and equipment can be made relatively small and inexpensive. Of course, it is also possible to heat the raw material plant at a temperature of 2000 ° C. or higher from the beginning and perform the melting treatment in a single heating step.

  The melted product thus obtained or its blend is mixed with general water, deionized pure water, or an aqueous solution or alcohol solution of pure vegetable vinegar in a ratio of about 1: 2 to 3, and heated. Next, after cooling, only the liquid portion can be separated from the mixture by filtration or the like to obtain a plant mineral extract with higher purity.

  Furthermore, according to the present invention, the liquid plant mineral extract thus obtained can be preferably concentrated to approximately 20% or more. In another embodiment, the moisture can be completely removed by solidification, such as by evaporation. The plant mineral extract thus concentrated can further delay the oxidation rate of the mineral contained therein, and can maintain an oxidation-reduction potential of approximately −200 mV or higher, that is, a high reducing power over a longer period. . Further, it is advantageous in use if the solidified powder is made into powder. It should be noted that excessive drying when solidifying may reduce the oxidation-reduction potential.

  As the raw material plant to be used, all plants existing on the earth can be targeted. For example, seaweed includes kelp, wakame, arame, hondawara, hijiki, and kamame. Land plants include tree leaves such as cedar, hinoki, kunugi, pine, nara, ginkgo, loquat, bamboo, bear pupa, itadori, kudu, mugwort, makomo, dokudami, sugina, licorice, watercress, seri, dandelion, swordfish, There are wild grasses such as sorrel and giant grass. However, these are merely examples, and the usable raw materials are not limited. Regardless of the type, in principle, it is preferable to select a plant having a vigorous fertility that grows naturally.

  There are no particular restrictions on the selection and combination of the raw material plants, but it is preferable to use a mixture of two or more terrestrial plants and seaweeds so that more types of minerals are contained in a balanced manner. The minerals contained in carbonized or incinerated products of raw materials contain a lot of calcium, potassium, chlorine, sodium, silicon, magnesium, phosphorus, sulfur, etc. Yes.

  Generally, the carbonized or incinerated products of plants have a reducing power that prevents a certain degree of oxidation as described above. However, depending on the type of plant, the carbonized or incinerated extract may not have a redox potential of −200 mV or higher. Accordingly, it is preferable to appropriately select and / or combine plant materials to be used so as to obtain a desired level of redox potential. In particular, it is preferable to exclude plant materials having extremely low reducing power. For this purpose, an aqueous solution extract of about 5% is prepared in advance for each kind of various plants, and the redox potential is measured in that state, and those having a high reducing power, particularly those having a redox potential of about −200 mV or more. It is preferable to sort things.

  The plant mineral extract of the present invention is not only safe for the human body by including minerals that are plant extracts derived from nature in this way, but also by oxidation reduction using the reducing power of the raw material by melting treatment. It has a high reducing power with an electric potential of about −200 mV or more and can be maintained for a long time. As a result, when this is taken directly into the human body, it has a beneficial effect on human health, such as enhancing defense functions against various lifestyle-related diseases and effectively improving diseases such as skin diseases. When used in the above, effects such as maintaining freshness, preventing oxidation, improving color developability and preventing fading, and excellent taste can be obtained.

  The present invention can be implemented by adding various modifications and changes to the above-described embodiments within the technical scope thereof. For example, in the method of carbonizing / ashing the raw material plant, as described in Patent Documents 4 and 5 by the inventors of the present application, the raw material plant is heated at the upper heating limit temperature of the mineral contained in the raw material plant, Other conventionally known methods such as heating and pulverizing at a temperature of 500 to 2000 ° C. can be used.

Example 1
Five types of plants, including terrestrial plants such as bamboo, Japanese knotweed, kayak, kunugi and seaweed Ascophyllum, were collected to remove foreign substances such as dust, soil and stones, washed with water and dried. Each plant was individually heated using a refractory gas furnace at a temperature of about 500 ° C. for a sufficient time, and the first carbonization and / or ashing treatment was performed. Next, this first carbonized and incinerated product was further heated at a temperature of about 900 ° C. using the same refractory gas furnace, and again carbonized and / or incinerated. Further, the carbonized / ashed product again was heated at a temperature of about 2000 ° C. and melted. In this melting process, a refractory steel cylinder is used, and the outer periphery of the cylinder is heated with a gas burner with a heating power of 2500 ° C. or more with carbonization / ashing product again in the cylinder, and the carbonization / ash inside the cylinder It was burned until the chemical melted and flowed out of the cylinder.

  After the first carbonization / ashing treatment, after the second carbonization / ashing treatment, and after the melting treatment, the first carbonization / ashing product, the second carbonization / ashing product, and the melted product obtained, respectively, The redox potential of was measured. The oxidation-reduction potential was measured by adding water to the obtained carbonized / ashed product and melt and heating until boiling, cooling and filtering with a filter cloth, adjusting the obtained filtrate to a 1% aqueous solution, The measurement was performed by measuring with an oxidation-reduction potentiometer (ORP meter).

  The measurement results are shown in Table 3 below. All the carbonized and incinerated products obtained by heat treatment at about 500 ° C. clearly had organic substances remaining, and the oxidation-reduction potential was at a low level. The carbonized / ashed product obtained by the heat treatment at about 900 ° C. shows that the redox potential is lowered by raising the heat treatment temperature above 500 ° C., indicating that it has a reducing power. It can be seen that the melted product obtained by the melting treatment at about 2000 ° C. has a significantly increased reducing power, although the oxidation-reduction potential differs depending on the type of plant. What is characteristic is that the blend of the carbonized and ashed products of each plant equally mixed and melted shows the second highest reducing power, which greatly affects the effects of plants with high reducing power. It is thought to have received.

(Example 2)
Collect wild plants kelp, wakame, arame, hondawala, ascophyllum, cedar, pine, hinoki, bamboo, kayak, kumazasa, mugwort, weedbird, wash them well and dry them, and then use a fireproof kettle alone. The mixture was heated at a temperature in the range of approximately 800 to 1000 ° C. to perform carbonization and / or ashing. This carbonized and / or incinerated product was sieved using a sieve of about 20 mesh, blended in equal parts for each grain size, and then heated at a temperature of 2000 ° C. or higher for melting treatment. To 30 kg of the obtained melt, deionized pure water was mixed at a rate of 100 liters, heated to boiling, and then cooled all day and night. The supernatant was first filtered using a commercially available filter cloth, then using a two-stage activated carbon filter, and further filtered through a filter with a filtration accuracy of around 0.5 μm. The oxidation-reduction potential of a 1% solution of the obtained filtrate was −500 mV or more. The filtrate was heated and concentrated to 20% or more, and further concentrated to solidify. It was confirmed that the redox potential of the obtained plant-extracted inorganic solid was -200 mV or higher.

  About these plant-extracted minerals and their 20% concentrated solutions and solids obtained by solvent extraction, those immediately after production, those after standing for 1 month and 3 months after standing at room temperature after production, are each 1% with tap water. It was set as the aqueous solution and those oxidation-reduction potentials (mV) were measured. The measurement results are shown in Table 4 below. A measuring instrument manufactured by Toa Denpa Kogyo Co., Ltd. (TOA) was used for the measurement of the oxidation-reduction potential. The redox potential of tap water used for sample dilution was 600 to 700 mV. From these results, it can be seen that the redox potential immediately after production, 1 month after production, and 3 months after production are substantially the same level. That is, it shows that the plant mineral extract according to the present invention can maintain a high reducing power for a certain period.
