DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for stabilizing the liquidity of wood vinegar used in various fields such as food processing, agriculture and pharmaceuticals. Specifically, the present invention relates to a liquid property stabilizing method for stopping or suppressing a change over time of a wood vinegar liquid and maintaining a desired liquid property for a long time.

[0002]

2. Description of the Related Art Wood vinegar is used as a fumigant or disinfectant for food processing, a repellent for pests and animals, a plant growth promoter, a soil improvement aid, a deodorant, a pharmaceutical, a water purification aid, a wood preservative. It has been used for a long time, but it has been rarely used since the emergence of chemicals. In recent years, in the field of agriculture, environmental pollution and harm to the human body by pesticides, resistance bacteria, and the decrease in the effect of pesticides on soil pests due to the emergence of resistant pests have become a problem. I have.

In the field of agriculture, black crude wood vinegar liquid obtained by carbonizing wood is left to mature for 6 months to remove light oil and tar, and has a reddish brown transparent feeling. A colorless and transparent distilled wood vinegar obtained by distilling a purified wood vinegar, a crude wood vinegar or a purified wood vinegar to remove a light oil component and a tar component is mainly used. These wood vinegar solutions have a bactericidal / insecticidal action, a substance dissolving action, a penetrating action into living tissues such as plants, a coenzymatic action, a catalytic action, etc. for reactions occurring in the living body and cell synthesis. Yes,
When used, they generally have such characteristics as disappearing and accumulating due to spontaneous decomposition and not generating resistant bacteria and the like.

[0004]

However, wood vinegar is
There is a drawback that the liquid property is extremely unstable, the change over time is apt to occur, and the characteristics such as functions and effects intended for use cannot be maintained for a long period of time. That is, the wood vinegar solution contains more than 200 kinds of substances and contains many organic substances. Therefore, if oxygen is present, oxidative polymerization is repeated and changes over time. In addition, it reacts sensitively to light and produces a separated substance that changes color to black, adheres to and sediments on the inner wall of the container, and changes over time in a short time. As the composition changes over time, the composition of the wood vinegar solution changes, resulting in different liquid properties. Therefore, it cannot be stored for a long period of time, and it is difficult to commercialize wood vinegar.

[0005] By the way, in order to stabilize the liquid properties, attempts have been made to leave the crude wood vinegar liquid for about one year and then to mature it. However, since the effective components of the wood vinegar are reduced and the original functions and effects of the wood vinegar are reduced, its use is limited to a narrow range. In addition, the liquid property cannot be sufficiently stabilized, changes over time during storage, and the liquid property at the stage of completion of ripening cannot be maintained.

[0006] Further, in order to compensate for the deterioration of functions and effects due to the aging, it has been attempted to add other substances. For example, when using wood vinegar as a pest repellent, garlic is added to the wood vinegar to enhance and maintain the pest repelling effect, and a high molecular weight adsorbent such as garlic and chitosan is added to the wood vinegar. That, to the wood vinegar liquid, adding a polymer extract such as garlic and chitosan and a plant extract having a specific insect repellent effect, and adding an enzyme such as cyclodextrin to dissolve the plant extract, It has been proposed to add a high molecular simulant such as garlic and chitosan, a plant extract having a specific insect repellent effect, an enzyme such as cyclodextrin, and a surfactant. However, in any case, the wood vinegar solution changes over time during storage, and its characteristics change, so that it is impossible to achieve the functions and effects of the intended use. In particular, in the case of adding the polymer pseudo-collection agent, there is a problem that tar generated in the process of spontaneous decomposition adheres to the polymer pseudo-collection agent and inhibits the function of the wood vinegar solution. Since a substance to which an enzyme such as cyclodextrin is added contains a substance having an attraction effect, it has an opposite effect of attraction after eliminating pests, and there is a problem that the effect as a repellent is diminished. . Further, in the case where the surfactant is added, since the surfactant does not disappear by spontaneous decomposition, there is a problem that the surfactant accumulates and causes environmental pollution.

[0007] On the other hand, the crude wood vinegar liquid begins to ripen from the moment it is collected, and has different liquid properties and different characteristics at each time point. Therefore, if it is possible to maintain the liquid properties at each time point, it is considered that the liquid properties can be used for applications that take advantage of the respective characteristics. For example, a remedy for athlete's foot using sterilizing / insecticidal action, a deodorant for human waste such as livestock using a deodorant action, and a repellent for pests / beasts using a peculiar smell of wood vinegar liquid. . However, since it is more likely to change over time than the purified wood vinegar solution and the distilled wood vinegar solution, it is difficult to set the liquid properties at each time point, and it is difficult to use the properties in a field that takes advantage of the characteristics.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional situation, and has as its object to stop or suppress the temporal change of wood vinegar in order to expand the range of use and product application of wood vinegar. It is an object of the present invention to provide a method for stabilizing a wood vinegar solution that can maintain liquid properties for a long period of time.

[0009]

Means for Solving the Problems In order to solve the above problems, a method for stabilizing a wood vinegar solution according to the present invention is a special alkali brewing method in which a wood vinegar solution is heated several times using rice and soybeans as raw materials. It is characterized by mixing the sugar-free alkaline enzyme components extracted by the method.

[0010] The special alkaline brewing method refers to a process in which brewing is performed with heating, brewing is performed while heating, saccharides are removed each time heating is performed, and heating is performed again multiple times. It is a brewing method performed by.
What is obtained by this brewing method is a sugar-free alkaline enzyme component obtained by removing sugars from the alkaline enzyme.
The wood vinegar liquid may be any of a crude wood vinegar liquid in the aging process, a purified wood vinegar liquid, a distilled wood vinegar liquid, and a wood vinegar liquid mixed with other substances.

[0011]

By mixing a sugar-free alkaline enzyme component into a wood vinegar solution, the oxidative polymerization reaction of organic substances in the wood vinegar solution and the polymerization reaction by light are stopped. As a result, the liquid property does not change even if it comes into contact with oxygen or receives light during storage, that is, the dissolved tar does not break out, and the desired liquid property is maintained. The mixing ratio of the alkaline enzyme component is extremely small. For example, it is sufficient to add 30 CC to 1 ton of wood vinegar.
Further, even if the mixing ratio is increased, there is almost no difference in the effect.

[0012]

Embodiments of the present invention will be described below. In the first embodiment, the stabilized wood vinegar solution was stabilized by mixing a sugar-free alkaline enzyme component extracted by a special alkali brewing method in which rice and soybeans were subjected to several heat treatments using rice and soy as raw materials. I went. Purified wood vinegar is a reddish-brown transparent one obtained by leaving the crude wood vinegar collected in the process of baking broadleaf trees such as oak, oak, beech, etc. on black charcoal with earthy cattle for about 6 months and maturing. is there. This purified wood vinegar solution was diluted with distilled water and adjusted to a 0-fold solution (stock solution), a 2-fold solution, a 3-fold solution, a 5-fold solution, and a 10-fold solution. Two solutions were prepared by injecting each solution into a 200 CC cylinder at a rate of 100 CC each. The alkali enzyme component was injected into one cylinder of each solution at a rate of 1/22 CC and mixed and stabilized. No stabilization processing. The cylinder of each liquid was sealed with an acrylic urethane lid, and left in a room at room temperature exposed to natural light. As a result, each liquid in the cylinder that had not been subjected to the stabilization treatment changed over time as shown in Table 1. That is, initially, the stock solution was a red-brown transparent liquid, and the color became lighter as the dilution ratio became higher. Deposits and suspended matter gradually increased up to about 4 weeks after standing, but a difference due to the dilution ratio could be confirmed. However, deposits and suspended matter were remarkably generated up to 8 weeks later.
By a week later, the dilution ratio changed to such an extent that it was impossible to determine the dilution ratio. On the other hand, the stabilized product showed stable liquid properties without any change, not to mention generation of deposits and suspended matters even after 6 months. And
For example, when used as a pest repellent, it showed the same repellent effect as at the beginning. It should be noted that, even if the mixing ratio of the alkaline enzyme component was increased or decreased, for example, increased to 1 CC, or decreased to 0.00003 CC, there was no change in liquid properties, and no difference in use was observed.

[0013]

[Table 1]

In the second embodiment, the pest repellent using wood vinegar was stabilized by mixing the above alkaline enzyme components. This pest repellent uses a purified wood vinegar liquid similar to the above as a wood vinegar liquid, is added with a plant extract component having a pest repellent effect, and is adjusted to obtain a synergistic effect with the repellent effect of the wood vinegar liquid. After adding the plant extract component, the alkaline enzyme component was mixed at a rate of 30 CC per ton. The component composition of the obtained pest repellent is as shown in Table 2, and the harmful substances in the components were significantly reduced as compared with the conventional pest repellent as shown in Table 3. In addition,
Similar results were obtained when the alkaline enzyme components were mixed before the addition of the plant extract components.

[0015]

[Table 2]

[0016]

[Table 3]

Even after standing for 6 months, deposits,
There was almost no generation of suspended matter, and stable liquid properties were exhibited. And, when used, it is naturally diluted with a certain quality, disappears slowly, and has a repellent effect of 7 to 1 in principle.
It lasted a relatively long time of 0 days. In particular, for carnivorous pests such as centipedes, the repellent effect lasted for 2 to 3 weeks because the repellent effect on insects and the like that became a bait eliminates the bait in the breeding ground. Since the liquid properties of the wood vinegar are stable during storage and decompose slowly when used, the effect of wood vinegar with the addition of surfactants and high molecular weight precipitants like conventional pest repellents Does not need to last. As for the plant extract component to be added in order to obtain a synergistic effect, it is sufficient to select one that dissolves in the wood vinegar solution as it is, and it is not necessary to inhibit the repellent effect itself or use a substance having a safety problem as in the past. . As a result, it is possible to obtain a pest repellent which has no harm to the environment and the human body by adding a minimum amount of plant extract components, has a high repellent effect, and can contribute to the natural environment when the decomposition process is completed. Was.

In the third embodiment, the above-mentioned alkaline enzyme component was mixed with a disinfectant or wood vinegar for treatment of athlete's foot and stabilized. That is, 3 tons per ton of crude wood vinegar liquid
The alkaline enzyme components were mixed at a rate of 0 CC and left for 6 months. As a result, there was no generation of deposits and suspended matters, and no change in liquid property was caused. And when it was used, athlete's foot was calmed and healed in the same manner as at the beginning.

[0019]

According to the present invention, by mixing a sugar-free alkaline enzyme component irrespective of the maturation stage of the wood vinegar solution, it is possible to substantially prevent the wood vinegar solution from changing over time. It became possible to maintain the liquid properties at the time of mixing the components. As a result, a wood vinegar solution having characteristics depending on the aging stage can be set, and the possibility of expanding the usable range of the wood vinegar solution, the product application range, and the like is obtained.

For example, when used as a pest repellent, there is no change over time during storage, whether it is a crude wood vinegar solution or a purified wood vinegar solution, and the liquid properties are stable for a long time. Decomposes slowly without breaking down harmful components such as minutes. Therefore, the repellent effect can be maintained for a longer period than before. In addition, when a plant extract component is added to enhance the pest repellent effect, since tar content hardly evaporates, a synergistic effect can be obtained by adding only the plant extract component that dissolves directly in the wood vinegar solution. it can. Therefore, it is not necessary to add a harmful plant extract component or a substance for dissolving the same as in the past, so that a pest repellent that can contribute to the natural environment without harming the environment, the human body, etc., can be obtained. Has become possible.

When used as a remedy for athlete's foot, a crude wood vinegar solution having a relatively strong bactericidal action is used. However, since it is set to a characteristic at a predetermined ripening stage and does not generate resistant bacteria, it is excellent in treating athlete's foot. It is now possible to get medicine.
