Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an aqueous humic precursor solution.

Recently, it has been found that humic precursor aqueous solutions can be effectively used for various purposes, and in view of the need for artificial mass production, this invention was developed as a result of many years of experimental research by the inventors. This is what was done.

(1) Therefore, an object of the present invention is to provide a method for producing a humic precursor aqueous solution that can be artificially mass-produced.

The feature of this invention is that humic plants stored in an anaerobic state are further stored in an anaerobic state for 15 days to 3 months, and after being turned over an appropriate number of times during this storage period, water is added to the humic plant.
Add either weak acid water or salt aqueous solution to reduce pn to 4.
．． The purpose is to adjust the pt+ to be within the range of 0 to 7.0, and then allow the filtered filtrate to stand still and age to bring pt+ within the range of 1.0 to 2.5.

The humic plant that is the raw material of this invention refers to humus containing a humus precursor or humus containing humus. Humus may be naturally occurring, artificially produced, or a mixture of naturally occurring and artificially produced humus. This humic plant is a mixture of organic matter and inorganic matter, and its composition ratio is 60 to 95% organic matter and 5 to 40% silicic acid compound, which is a mixed reaction product of inorganic matter. Also, (2
) The composition ratio of this silicate compound is andesite and rhyolitic, 5to2 is 52 to 75%, and FeO.

Fe203 is 3 to 13%, the remainder is Al10B, C
aO.

MgO, Na2O, K2O, H2O, etc. To artificially produce this humic plant, a metabolite or a substance containing a large amount of a metabolite, a substance containing a large amount of activated silicic acid as an inorganic substance, and an organic substance are mixed in appropriate amounts and stirred. This is done by ripening. here,
Metabolites are the secretions of bacterial groups including aerobic bacteria, trifacultative anaerobic bacteria, aerobic bacteria, and facultative anaerobic bacteria, and are compounds with exposed phenol groups and oxidizing enzymes such as phenol oxidase, or phenol. It refers to a mixture of compound oxides such as quinones, polysaccharides, and aranoic acids. Substances containing large amounts of these metabolites include sludge or sludge-like substances, humus, humic plants, and grass charcoal.

There are humus precursors contained in peat, lignite, etc. Substances containing a large amount of activated silicic acid include fine powder of volcanic glass such as andesite, rhyolite volcanic ash and pumice, clay minerals, and zeolites derived from green taff (3). ) (zeolite) Examples include fine rock powder mainly composed of minerals, and finely powdered diatomaceous earth.

The term "humic precursor" is a general term for intermediate products in the material transformation process leading to humus in organic matter, and includes metabolites and trace amounts of metals such as silicic acid and iron.

The reason for preserving or producing the humic plant in an anaerobic state is
Promotes the reaction of three substances contained in humic plants: organic matter, metabolites, and substances containing a large amount of activated silicic acid, and stabilizes, activates, and metabolizes the reaction products produced by this reaction. This is to stabilize the phenol etc. contained in the product.

Then, while preserving it in an anaerobic state for another 15 to 30 days,
Make a switch. It is best to carry out this cutting once or twice a week, but the purpose of this cutting is to increase the amount of quinones by allowing oxidizing enzymes to act on phenolic compounds, but too much cutting If this is done, excessive oxidation occurs, so (4) appropriate cutting is necessary.

After such preparations are completed, either water, a weak acid, or an aqueous solution of salts is added to adjust pi to within the range of 4.0 to 7.0. Those that dissolve within this pH range are humic precursors. If the pH is lower than the lowest value, extreme oxidation will proceed, leading to a decline in functionality, and if the pH is higher than the highest value (if the pH is higher than the highest value, extraction will become difficult due to coagulation of humic precursors, etc.). It has been experimentally shown that the amount of aqueous solution to be added is approximately equal to the amount of humic material as the raw material. This is because the concentration of the humic precursor to be added becomes too dilute.However, since extraction is possible as described above even if the amounts are not equal, the amount of the aqueous solution added is not limited.

Once the humic precursors have been extracted, filtration is then performed.

Since this filtration is a separation of the solid humus and the aqueous solution or liquid from which the humus precursor has been extracted, any method that allows solid-liquid separation may be used. However, (5) pressure separation is most desirable in order to extract more humic precursors adhering to the surface of the solid.

The filtrate obtained by filtration is stabilized by standing and aging, and as a result, the pH becomes within the range of 1.0 to 2.5.・This is an aqueous solution of humic precursors. For stabilization, a period of at least 10 hours or more is required for the static aging. During this static aging, the pH decreases and becomes stable because
This is due to the conversion of phenolic compounds into quinones by the catalytic action of oxidizing enzymes in an aqueous solution.

The humus precursor aqueous solution produced as described above has the following uses.

B. Application to the immobilization of organic volatile components Due to the action of microbial metabolites contained in humic precursors, organic volatile components are converted into macromolecules through polycondensation reactions. The substance can be used as an additive to prevent bad nests and to prevent fragrance components from escaping.

Application to food processing By utilizing humic precursors, it is possible to induce polycondensation reactions (6) and enzymatic reactions of organic substances.
It can be applied to separation operations in food processing and the development of new foods.

C. Application to pharmaceuticals, etc. Humic precursors that contain large amounts of microbial metabolites are mainly aggregates of active substances, and microbial metabolites strongly promote the polycondensation reaction of organic substances, and humic precursor aqueous solutions are Chain reaction through biomembranes such as cell membranes and biomaterials;
It is particularly effective in inactivating, rendering harmless, and reducing human and animal pathogenic substances (including microorganisms such as viruses and bacteria) because of its excellent anti-inflammatory properties. By taking advantage of this property, it can be used as a raw material for various pharmaceuticals (for humans and livestock), agricultural chemicals, cosmetics, and the like.

2. Application to the operation of delaying the decay of putrefying organic matter By adding an aqueous solution of a humic precursor to the putrefying organic matter, it contributes to delaying the putrefaction of the putrefactive organic matter.

Next, an example of the method of this invention will be described.
