[Industrial use]

The present invention relates to an extracting method and an extracting device of the lacquer extract, and more specifically, does not change the components or content of the lacquer extract by not mixing additives such as medicinal herbs or organic solvents, The present invention relates to a method for extracting and extracting Rhus verniciflua extracts capable of food processing such as beverages, by extracting a large amount of highly purified urushiol-based compounds by direct heating and distillation with steam without directly contacting them.

[Prior art]

As human cells age, repeated accumulation of harmful actions by harmful radicals causes aging of cells as well as diseases related to various adult diseases such as carcinogenesis, arteriosclerosis, heart disease, and skin aging. Antioxidants have been studied in various ways as a substance that can achieve the disease-free longevity, which is the dream of humans, by removing harmful free radicals related to the disease.

A lacquer is a mixture of urushiol derivatives, such as urushiol and cidrorushol, contained in the rubbery suspension contained in the lacquer. In general, look at the structure of the lacquer tree is composed of the bark portion and the wood portion that contains a lot of sidrou Luciol component to raise the lacquer.

In ancient times, Dongbobogam and herbaceous wood have been described as the name of the world's best medicine when it handles the toxicity of lacquer, and Uiseong Heojun in Joseon Dynasty said, Kills and relieves fatigue. " Pharmacological action has been described as bruises, blood formations, pain in women, lower back and lower abdomen, used for painful diseases, repellents, and bowel movements (Hwang Do-yeon, Chemo 550 (1993)). It is light and effective in suppressing old age, and its use is increasing rapidly, such as processed and eaten with lacquer chicken, and it has been announced that it has the effect of treating and inhibiting various cancer cells identified by modern medicine, preventing adult diseases and preventing peroxidation. It proves to be consistent.

Kim Il-hoon Phosphate described in his book Salvation Atrial that "lacquer is as important and effective as wild ginseng," he said, which is a digestive agent in the stomach, a blood pill in the liver to cure inflammation, and a blue blood in the heart. It kills the tuberculosis bacillus, and it is used in the kidneys to cure the diseases of the five intestines, and it is praised as a great medicine for neuralgia, arthritis and dermatitis. He also mentions the anticancer effect of lacquer, "the lacquer is the best natural preservative and must be used for the fundamental treatment of cancer" (Kim Il-hoon, Salvation Chamber 58, 208, 350 (1992)). It was confirmed in fact in scientific studies one after another.

The Korea Institute of Science and Technology (KIST) found the urushiol component in the sap of domestic lacquer in 1997, and tested it on human cancer cell lines at a concentration of 3 to 4 ppm and showed excellent anti-cancer activity for killing cancer cells. In particular, the sap of Gangwon-do Wonju acid lacquer was analyzed to be 50% by weight of urushiol component, it was found that the lacquer itself is just like an anticancer agent. In addition, urushiol, which is a health ingredient mainly extracted from the gallbladder of bears, is known to have twice the ability of tocopherol to promote the aging of the human body and to remove free radicals that cause various diseases.

The Forest Service Forestry Breeding Research Institute also analyzed the urushiol component of lacquer sap and extracted the anti-cancer effect Mu-2 component. Mu-2 is extracted from Hwachil obtained by heat-treating cut lacquer tree and is known as a complex of five substances with excellent anticancer effect and no allergic reaction and no acute toxicity. The researchers found that the substance was found to be much more effective at inhibiting the growth of animal blood cancer cells, human lung cancer cells, and gastric cancer cells than the existing anticancer drug, tetraplatin. As a result of comparative analysis of the anticancer effect of tetraplatin, it was found that Mu-2 exhibited the same cancer cell growth inhibitory effect even when administered in a much smaller amount than tetraplatin. It replaces proliferating cancer cells with normal cells and inhibits the angiogenesis necessary for oxygen supply during cancer cells' proliferation, thereby preventing the rapid proliferation of cancer cells that may appear after tumor incision surgery. In addition, Mu-2 said that in addition to its anti-cancer effects, Mu-2 also has antioxidant (anti-corruption) and hangover-relieving functions.

Compounds extracted from lacquer trees contain powerful natural antioxidants, and efforts to develop alternative materials that can be used to treat overwork, functional drinks, foods, pharmaceuticals, etc. can be used to treat overwork, stress, and adult diseases. It is being tried.

In addition, the patent documents related to the lacquer extract, the Korean Patent Application Nos. 97-036844 and 97-013163, the contents of the lacquer extract and the composition comprising the same and the urushiol fraction and the separation method thereof Is disclosed. However, the conventional techniques including the above are processed by changing the composition or content of the extract by adding an organic solvent such as ethanol, acetone, hexane, using only wood, or mixing additives of other materials such as lacquer, chestnut bark and willow. By extracting, the processed extract can not be immediately processed into food, such as beverages, there is a problem that the purity of the urushiol-based compound from which the toxicity is removed, there is a limit to extract in large quantities.

The present invention is to solve the problems of the prior art, by not mixing the additives, such as medicinal herbs or organic solvents by changing the composition or content of the extract, the high purity of the toxic that can be processed into food, such as beverages are removed An object of the present invention is to provide an extraction method and an extracting device of the lacquer extract which can extract a large amount of urushiol compounds.

Hereinafter, the present invention will be described in detail.

Oak trees are distributed evenly throughout Korea, and it is reported that trees that are planted in Wonju and Hoengseong, Gangwon-do contain the most urushiol components. Therefore, oak trees all over Korea, preferably the elder tree of Wonju is collected for the production of lacquer extract.

Since the lacquer of 3-4 years old contains almost no urushiol component in the ring of the ring of rings, and the older the age, the higher concentration of urushiol compound can be obtained. Therefore, in order to extract the high-quality urushiol compound, it is more than 8 years old, preferably 10 Harvest oak trees over a year old.

If the sampled oak tree is chopped finely without undergoing a drying process, it is difficult to extract high-quality compounds when the lacquer sap is exposed to a cut surface and dried while being oxidized. Therefore, the collected oak tree is cut as long as possible to about 1 to 3 m, and the cut lacquer tree is separated into wood and bark and dried in a cool and shady warehouse for about 90 to 120 days. The dried lacquer wood part is processed with sawdust or wood chips and the bark is cut and used to 10 to 15 cm.

After drying the processed sawdust or wood chips, cut bark, or a mixture thereof into the lacquer extract production tank, the water is added, the lacquer extract production tank is heated to prepare the lacquer extract to remove the toxicity by boiling water.

The ratio of the wood portion and water of the oak tree, the ratio of the bark and water, the ratio of the mixture and water can be obtained in any amount of the present invention. When the lacquer extract production tank is slowly heated for 12 to 14 hours while adjusting the steam discharge control valve to generate steam, it is possible to obtain an extract compound of the lacquer tree, in which approximately 1/2 of the amount of water first introduced is removed. .

The bark part is the main material in the wood part of the oak tree because there is almost no cydrurushol, a substance that raises the lacquer. About 1 to 3 kg of oak bark is used for 10 to 30 l of water. First, fill the lacquer extract production tank with 40 liters of water at the rate of 50 to 100 g of oak bark with respect to 1 to 2 liters of water, and the bark is 30 to 50 cm from the top or 10 to 15 cm from the lid Placed in a stainless steel basket located in the lacquer extract manufacturing tank. After that, start heating and when water starts to boil, adjust the fire power appropriately so that steam can be released between the caps when steam is generated. Boil slowly and continuously for 12 to 14 hours to obtain detoxified compounds extracted from the bark.

In addition, in order to manufacture the lacquer wood part, bark, or extract of the lacquer wood part and the bark mixture, first extract the oak tree more than 8 years, cut it for 3 m long and dry it at 55 ℃ for 90 days, then using a sawdust maker It is processed into sawdust of lacquer wood, bark, or a mixture of lacquer wood and bark. Thereafter, 2 kg of lacquer sawdust is added to the lacquer extract production tank 10 at a rate of 50 g of lacquer sawdust per 1 liter of water, and 40 liters of water is added to form a mixture 38 of water and lacquer sawdust. Compressed air per liter of water through the compressed air transfer pipe 82 by adjusting the steam discharge control valve 40 and operating the compressed air generator 14 to adjust the air injection control valve 72 so that steam can be discharged. After supplying the compressed air at an air injection rate of 1 L / min or more and generating bubbles 36 from the bubble generator nozzle 62 installed in the lacquer extract production tank 10, the water was boiled slowly and continuously for about 14 hours. A brown oak extract compound with about 20 liters of toxicity removed can be obtained.

In addition, in order to remove the residual toxicity of the produced lacquer extract compound contained the extracted compound in the lacquer extract production tank (10) the air generated in the compressed air generator (compressor) 14 to the compressed air transfer pipe 82 When compressed air is injected at a rate of 0.1 l / min of compressed air per liter of the extracted compound to generate bubbles 36 from the bubble generator nozzle 62 installed in the lacquer extract production tank 10, residual toxicity is observed after about 48 hours. This removed oak extract compound can be obtained.

The sap and bark parts of the oak tree contain the best urushiol compounds and must therefore be given optimum conditions for drying and processing.

Due to the low toxicity of lacquer during processing extraction of wood parts, there may be slight differences in the hole, temperature, processing, and extraction time of the steam discharge control valve of the lacquer extract manufacturing tank, but boiling during processing extraction of bark or mixed materials Careful management and skills are needed to adjust the water temperature, steam generation and steam temperature, and the adjustment of the steam discharge control valve.

The material and design of the lacquer extract tank is closely related to the water level, the position of the stainless steel basket containing the wood chips or sawdust, the height of the lid and the position of the steam control valve. Here, the stainless steel basket is installed by adjusting so that the wood chips or bark does not directly contact the water.

Hereinafter, the operation of the present invention will be described with reference to FIG. 2. Water and lacquer raw materials are added to a stainless steel basket 20 installed inside a steam production tank 12 and a lacquer extract production tank 10. When the steam production tank 12 is heated in a closed state, water contained in the steam production tank 12 is boiled to generate water vapor, and the generated water vapor is produced through the water vapor transfer pipe 80 to extract the lacquer extract tank 10. The lacquer extract extract is extracted by heating the lacquer raw material that is introduced into the stainless steel basket 20.
