Description

[0001] The present invention relates to a method for extracting lacquer from a lacquer tree,

More particularly, the present invention relates to a method for effectively removing the toxicity contained in a lacquer tree in a lacquer tree leaf and a seed containing a little less amount of liquid than a liquid generated from the stem of a lacquer tree, The present invention relates to a method of extracting lacquer from a lacquer tree leaf and a seed which effectively extracts beneficial components contained in the plant.

As is commonly known, lacquer (or lacquer) refers to a lacquer that comes from a wound on a lacquer shell.

As it is already known, it is known that lacquer is effective in preventing blood circulation and poor blood circulation, resulting in poor blood circulation, poor physiology, poor digestion, and elimination of tumor and parasite killing.

Studies have also been made on the anticancer activity and the survival rate of cancer patients. It is known that there is an analgesic effect which helps to relieve hangovers by helping the liver to detoxify and alleviate pain in athletes and cancer patients who have lost their performance.

'Flavonoid', a component of lacquer, inhibits the oxidation of our body and prevents aging. 'Trehalose' prevents the protein from changing and improves the taste and flavor of the food.

Especially, it is reported that when food is stored or stored in a lacquered tableware, it is antimicrobial to food poisoning bacteria such as O157.

According to a recent study by the Korea Advanced Institute of Science and Technology, urushiol component of lacquer has a strong anticancer effect, and it has an effect of killing cancer cells at the concentration of urushiol 4PPM, and the flavonoid component contained in the lacquer tree inhibits cancer cell growth of liver cancer And to differentiate cancer cells into normal cells.

On the other hand, urushiol contained in lacquer is also toxic. When uriciol, which is volatile, is absorbed into the skin cells of the body, it mostly causes various skin diseases.

Therefore, in order to process lacquer and use it as food or functional material, it is necessary to completely remove toxic substance called urushiol.

Applicants have applied uriciol, which is a toxic substance contained in lacquer, to various products such as functional soaps and functional herbal preparations.

For example, Patent Registration No. 10-938461 entitled " Soap containing anti-alopecia powder and its preparation method ", Patent Registration No. 10-938462 entitled "Soap containing lac- 593469, " a method for preparing a herbal medicine containing lacquer, " and a patent registration No. 10-2017-0122485, " a method for producing a non-toxic lacquer powder "

However, the prior arts registered prior to the present application are intended to produce powders after removing the toxic substance of urushiol contained in the poisonous lacquer, and when the lacquer powder is applied to the actual product soap, the lacquer powder is exposed to the surface of the soap, There was a problem that it was burdensome or was reluctant to be used by the powdered lacquer.

Therefore, it maintains the beneficial ingredients of the lacquer and extracts the liquid lacquer solution from the liquid without removing the unproductive components, and comprehensively applies the extracted lacquer solution to various products such as food and beverage, cosmetic products for skin care, soap, toothpaste Development is urgently required.

Due to this demand, various methods have been proposed by the lacquer liquid extraction method.

One of them is Korean Patent Laid-Open Publication No. 10-2002-0004800 entitled "Extracting Method and Extraction Apparatus for Rhus verniciflua extract."

The method of extracting and extracting the Rhus verniciflua extract has been proposed in which the wood part and the skin of Rhus verniciflua are finely pulverized and heated with steam to remove the toxicity and extract the extract.

As another example, Korea Patent Registration No. 10-0367286 entitled "Method for Extracting Poisonous Rhus verniciflua extracts"

The method for extracting the toxin-free Rhus verniciflua extract is as follows. The lacquer solution is collected from a lacquer tree of 5-6 years old after planting, and the collected liquid is dissolved in an organic solvent such as ethanol, methanol, acetone or chloroform, And dried in a hot air dryer at 100 - 400 ° C for 3 - 24 hours to remove toxic substances.

Therefore, in the above extraction method, there has been a problem in that an organic solvent such as ethanol, methanol, acetone, chloroform or the like which is harmful to the human body must be used in order to remove toxicity.

On the other hand, in the case of using the lacquer extraction method as described above and other known lacquer extraction methods in common, only the bark of lacquer which has the highest amount of liquid is used, or the lacquer is extracted from the lacquer tree Most of them were.

In order to extract the extract from the lacquer tree bark, most of the toxins of urushiol, which is the most abundant in the bark of the lacquer tree, have been removed. Therefore, in order to extract the effective components of the lacquer tree, There was a problem that we had to remove toxic substance called urushiol through effort.

On the other hand, in the above-mentioned various methods of extracting rubrum, most of the raspberry sap (fresh juice) is made from roots and leaves, seeds, Many people who are not well aware of the fact that they have repeatedly used only a number of methods already known to remove toxicity from the lacquer juice and then eat it.

FIG. 1 is a process drawing showing a step of extracting a rush of lacquer leaf of a lacquer tree in the first embodiment according to the present invention
FIG. 2 is a process diagram showing a step of extracting a rush of lacquer from a lacquer seed of the second embodiment according to the present invention
FIG. 3 is a process chart showing a step of extracting a rush of lacquer from a lacquer tree leaf and a seed according to the third embodiment of the present invention

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1 to 3 show process steps for collecting a rush of lacquer in a mixture of lacquer leaf, lacquer seed, lacquer leaf and lacquer seed of a lacquer according to the present invention.

In particular, the method of preparing each raw material from a mixture of lacquer leaf, lacquer seed, and lacquer leaf and lacquer seed is different, but the method of collecting the raw lacquer solution from each prepared raw material is the same.

Therefore, a process for preparing each raw material, and a third embodiment for extracting the raw lacquer solution by mixing the respective raw materials will be described.

Lacquer seed crushing step

Collect the lacquer seeds and put them in containers filled with water.

After a certain amount of time, most of the lacquer seeds will sink, but the impurities mixed with the lacquer seeds floating in the water, which is called the lacquer, float in the water.

After removing the chaff and impurities as described above, high quality lacquer seeds that have settled down are recovered, dried and crushed.

It is effective to crush the seedlings by a pulverizer in a crushed state after milling because the hardness of the lacquer seeds is high.

Deposition step

The lacquer leaves collected before the autumn leaves and the crushed lacquer seeds are soaked in any one of the deposits selected from the group consisting of purified water, saline solution and persimmon vinegar, During the deposition.

Of course, it is effective to deposit the crushed lacquer seeds in a separate net while being separated from the lacquer leaves, but it is also possible to immerse the lacquer seeds mixed with the lacquer leaves in the crumb net to which the crushed lacquer seeds can be hanged.

The first drying step

After completion of the dipping step, the lacquer leaves and the crushed lacquer seeds which are wetted sufficiently in the dipping water are removed and, if possible, the lacquer seeds are firstly dried in a shade or dryer at room temperature except for the subzero temperature.

In the primary drying, 100 parts by weight of the raw material of the lacquer tree before the first drying and the lacquer seed of the pulverized lacquer are dried until the weight of the dried raw material is 100 to 120 parts by weight, respectively.

Extract liquid raw material mixing step

After completion of the first drying step, dried lacquer leaves are pulverized, and the pulverized lacquer leaves are mixed with the pulverized lacquer seeds to prepare an extract raw material.

In this case, it is possible to crush the mixed lacquer seeds together during the crushing process of the dried lacquer leaves. However, when the lacquer tree leaves are not mixed with the lacquer seed and the lacquer seeds are dried, only the lacquer leaves are crushed separately, .

Mixing step

10 to 30 parts by weight of a liquid selected from the group consisting of purified water, raw lacquer and saline, or a mixture thereof is mixed with 70 to 90 parts by weight of the raw material obtained by mixing the pulverized lacquer seeds prepared as described above and pulverized lacquer leaves.

It is effective that the mixing ratio of the mixture and the mixed solution is 100 parts by weight in total. However, 10 to 50 parts by weight of the liquid mixture may be suitably mixed with respect to 100 parts by weight of the raw material obtained by mixing the crushed lacquer seeds and the crushed lacquer seeds.

Secondary drying step

After the completion of the mixing step, the raw material of the extracted extract is secondarily dried in a shade or dryer except at a subzero temperature.

As in the case of the primary drying step described above, the drying is continued until the weight of the raw materials is maintained between 100 and 120 parts by weight in the secondary drying step.

The first toxicity removal step

After the completion of the second drying step, the dried extract raw material is put into a pressure vessel, and the toxicity is removed by steaming at a temperature ranging from 120 ° C to 160 ° C for 1 to 3 hours.

The reason for maintaining the temperature range of 120 ° C to 160 ° C as described above is the minimum temperature condition for removing the poisonous substance called urushiol contained in the rush leaves and seeds at 120 ° C or lower, And the toxic substance called urushosil contained in the seeds can be effectively removed, but odor can be generated from the lacquer tree leaf and the seed of the lacquer tree.

Third drying step

After the completion of the first toxicity removal step, the extract liquids containing moisture are tertiary-dried in a shade or a dryer at room temperature except for the subzero temperature.

At this time as well, the liquid of the liquid for mixing the raw materials to be extracted is dried until the weight portion of the raw material of the extract is faded to 100 to 120 parts by weight.

Extraction step

After completion of the third drying step, an extractive raw material which maintains 100 to 120 parts by weight, that is, a mixture obtained by mixing the pulverized lacquer leaves and seeds with purified water, raw lacquer, or saline, is added to the still .

At this time, 100 to 380 parts by weight of water is contained in the still, and a tray containing the raw materials of the extract is placed in the upper part of the still.

In the above-mentioned state, the internal temperature of the still is maintained within the range of 140 ° C to 200 ° C, and the still is heated.

At this time, the internal temperature of the lowest 140 ° C is a condition for removing secondary toxicity remaining in the mixture, and the internal temperature of 200 ° C or lower is such that vapor generated as water boils passes through the mixtures, It is for this reason.

The steam is passed through the mixture as described above, and the steam discharged to the outside, that is, the crude liquid distilled until 90 parts by weight of the mixture condensate is added, is extracted.

Although the process of extracting the extract with the lacquer leaves and the lacquer seeds mixed has been described so far, the lacquer leaves and the lacquer seeds were subjected to the procedures described above with reference to Figs. 1 and 2 of the accompanying drawings, Of course, be extracted.

On the other hand, the extracts obtained from the lacquer leaves and the lacquer seeds obtained by the above process show that urushiol, which is a toxic substance contained in the lacquer tree leaves and seeds, is completely removed, but the beneficial components contained in the lacquer trees, 'Flavonoids' that inhibit aging, prevent the protein from changing, and improve the taste and flavor of the food 'trehalose' ingredients remained intact.

Therefore, even if the raw lacquer solution extracted by the above-described process is consumed as drinking water, side effects such as allergy do not occur. Therefore, beneficial ingredients contained in the lacquer tree can be ingested by drinking the raw solution.

However, since a plant-specific odor may be generated among a number of processes which are steamed and dried to extract the Rhus liquorice stock solution, a separate plum extract functioning as a spice, a fruit extract selected from a variety of fruit extracts or honey is added as a sweetener You may consume the beneficial ingredients contained in the lacquer tree by drinking it.

On the other hand, such a lacquer solution as described above may be used as drinking water to be used for cooking rice, and may be given a beneficial ingredient for the health of the family members, and may be substituted by soup for domestic or hot pot.

When the raw lacquer solution is used as a raw material for soap and foam cleansing, it is possible to impart transparent soap and excellent skin protection function.

It can also be used in shampoos and hair rinses, nourishing hair roots and hair, and optionally being used in cosmetics.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and the scope of the present invention is indicated by the appended claims rather than the foregoing detailed description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
