Description

  The present invention provides safe environmental impact of useful plant-derived components from medicinal herbs, vegetables, fruits, flowers, trees, etc. that are directly ingested by the human body, using two aqueous solutions of antioxidants, catechin and vitamin C, having strong reducing power as solvents. The present invention relates to a production method for extracting the product and its extract.

  Conventionally, in addition to cooking, extraction of plant-derived components has been used as a “medicine liquor” that can be used by boiling a so-called decoction of a dried product such as a medicinal herb or herbal medicine or soaking in shochu for a long time. Extraction of drinks, health foods and medical products includes those using organic solvents such as alcohol, those using boiling steam extraction, and those obtained by immersing water for a long time. In the case of extraction with hot water, there is a loss of components due to heat and outflow of unnecessary residues due to cell destruction, while those with organic solvents have drawbacks such as removal of alcohol such as reduced pressure after extraction, and water extraction is slow There are a lot of ingredients that cannot be extracted.

  Recently, new technologies such as supercritical CO2 extraction have been carried out, but expensive and large-scale equipment is required.

Catechin, which is mainly a source of astringent green tea, is known to have antibacterial and antibacterial effects of cholera bacteria, food poisoning-causing Staphylococcus aureus and O-157 bacteria, and influenza viruses. It also has the effect of enhancing immunity by increasing human B cells and increasing the ability to produce antibodies. Vitamin C is also known for its antiviral action and food freshness-keeping action, but catechin and vitamin C are strong antioxidants that reduce their surroundings by oxidizing themselves. Will be completed and strengthened.
Catechin is the main and vitamin C is the subordinate. (Tadakatsu Shimamura)

I. In the case of water extraction, there are many components that cannot be extracted so much due to slow extraction.
B. In the case of boiling or heat extraction, there are loss of vitamins and other components due to heat and contamination of unnecessary residues due to cell destruction.
C. In the case of organic solvents such as alcohol, post-treatment of the solvent after extraction is necessary, and there is a burden on the environment.
D. “Drugs” and “fruit wines” use the extraction effect of potable alcohol, but the extraction takes a long period of several months or more.
E. In the case of CO2 supercritical extraction, a complicated apparatus is required and the cost is high.
F. For elderly and sick people, the process of decocting or cooling herbal medicine is difficult. Make it easier to take.
G. It is desirable for elderly people who have become thin to eat effective ingredients such as fresh vegetables and fruits without having to eat a lot. I want liquids like vegetable extracted tea and fruit extracted tea.

  By using catechin and vitamin C aqueous solution as a solvent according to the present invention, the extraction ability of 2 times or more to several times as compared with water extraction was confirmed. Cut large ones into appropriate sizes and thicknesses, whether raw or dried, small ones such as peanuts are seed-coated beans and warm pressurizing for industrial use However, in most cases, extraction is started immediately after submerging in a stationary state except for light agitation to make the concentration of the solvent uniform in the middle at normal temperature and normal pressure. It can be used as it is in 30 minutes, and can be used as it is. If it is too dark, it can be diluted with water. Ingest and adjust the taste. Most extractions are done within 24 hours. In the case of a material that easily oxidizes, it can be extracted even at a low temperature such as a refrigerator.

  When storing, boil the extraction solvent once and fill it into a narrow glass bottle and cover it, or cool it and pack it into a plastic bottle and store it in a refrigerator.

The present invention is useful for humans other than medicinal herbs, vegetables, fruits, flowers, trees, etc. that are poisonous and plants that have unclear components that are harmful to catechin and vitamin C. Suitable for extraction of active ingredients of all foreign plants, natural extraction at normal temperature and pressure, still state, no unnecessary residue mixed, no need to clean up the catalyst, complicated equipment is unnecessary and low It is cost and can extract the active ingredients of all plants. From 30 minutes to a whole day and night, you can obtain an extract solution that is rich in flavor and aroma that is unique to the ingredients and can be used immediately. Since the solvent is a healthy natural product, it is safe and secure. Extraction can be made raw, dried, peeled, or peeled. If the extracted solution is too thick, it can be diluted with water or adjusted with green tea and used as is. If the extracted solution has a smell or astringency, it can be easily ingested by heating after extraction, boiling or microwave heating. The smell of raw odor disappears even at the temperature before boiling. Concentrated extracts and fermented extracts are highly nutritious and can be used in other processed foods, beverages and dishes. Since it can be extracted without peeling off the seed coat, the beans can be used for other purposes. (Peanuts, black beans, etc.)
The cereal can be extracted, for example, as brown rice, or it can be extracted only by its natural extract from its germ or rice bran. By catechin immersion treatment, sterilization of food poisoning bacteria is performed simultaneously with extraction. This can be said to be an excellent feature of the catechin solvent when extracting useful food ingredients. Adding vitamin C enhances extractability and storage stability.

  Compared to the conventional health tea, which is extracted by heating, boiling, pressurizing and decompressing, and adding other ingredients to the extract, this manufacturing method is compatible with catechin solvents. The desired extracted tea can be obtained simply by mixing and immersing a plurality of good ingredients in appropriate sizes and thicknesses. Medicinal liquor and fruit liquor soaked in medicinal herbs need a aging period of several months to several years, whereas medicinal tea produced with this extract is produced in a sufficient concentration in a short time of several tens of days to one day. Is done. Therefore, fresh materials can be used. It can be taken by girls, children, and elderly people who are vulnerable to alcohol. Active ingredients that have not been readily available until now (such as onion skin) can also be used. In addition, the rich extract and rich flavor unique to each of these materials are rich in nutrient components, so that various germs in the air are easy to propagate and easily deteriorate due to oxidation. In order to make this a stable food, it is indispensable for concentrating and fermenting it with lactic acid bacteria, koji molds, acetic acid bacteria, etc. in order to improve the storage stability and improve the quality of active ingredients.

  In addition, since the present invention is excellent in extracting active ingredients of dried plants, various Chinese herbal medicines can be extracted with a green tea extract— “Chinese herbal green tea”. Green tea is one of the Chinese herbal medicines, and no harmful Chinese herbal medicines have been reported so far. There are about 500 kinds of Japanese herbal medicines, but you can use “Chinese herbal medicine green tea in small plastic bottles” and tea pack herbal medicines extracted from cold green tea, and you can expect a synergistic effect between the active ingredients of green tea and herbal medicine. Unlike chemicals, they are all natural products, safe and secure, and can provide medical care that is gentle to the body.

For plants, important seeds that inherit the offspring store various antibacterial and antioxidant components in seed coats to protect them from harmful external enemies, various bacteria, and the sun's strong ultraviolet rays. It is a plant-derived useful ingredient that is very effective for humans.
The present invention also exhibits excellent power for extraction of polyphenols. Various seed coat extracted tea is produced. (Eg, peanut seed coat extract tea, grape seed coat extract tea, onion seed coat extract tea, chestnut astringent peel extract, kankan seed coat extract tea)

      Coffee is roasted or cultivated coffee beans, but according to the present invention, coffee green tea can be made by cultivating and then immersing green tea. Grain black rice, cultivated peanut Valencia-type purple beans, Canberra grape black peel, blueberries, lotus cups, purple peach, grapes, black beans, etc. When extracted with green tea, purple, strawberry and black green tea are produced.

  In order to know the ability of the catechin solution of the present invention as a solvent, the date varies with the progress of research, but the same dry seeded peanut with seed coat is used for 3 hours in an 80% ethanol solution, which is a typical solvent widely used in the past. When extraction was performed for comparison under the conditions, even the commercially available green tea concentration was not inferior or more than that (Fig. 5).

  The fruits of Chiba Prefecture's Kyoho grapes were carefully peeled, and the lightly squeezed peels were immersed in the same catechin solution under the same conditions for 1: 1.1 for 3 hours to obtain resveratrol extraction (FIG. 6).

  The appearance of “Chinese herbal green tea” in small plastic bottles that can be easily used by elderly and ordinary people, and “Resveratrol green tea” and “High polyphenol green tea” that expand the value of green tea are expected. In addition, "organic raw vegetable extract", "fruit peel extract", etc. that are not juice squeezed by breaking the cell membrane are also expected. According to the present invention, extraction, discovery, and utilization of unused active ingredients contained in bark, pericarp, seed coat, bulbs and the like are expected.

  A method for producing “peanut seed coat health tea” by extracting seed coat active ingredients of dry peanut with seed coat. The dried peanut with seed coat of Yachimata Chiba semi-vertebrate seed was immersed in a catechin solvent containing vitamin C for 3 hours, and then the extraction solution was taken out. As for the catechin solvent, commercially available 2L green tea (sencha) plastic bottle containing vitamin C is used as it is as a solvent. Vitamin C is used in small amounts to prevent browning of green tea. Since peanut beans vary in size, they were soaked in a beaker at a ratio of 1 to 1 catechin solution in the weight ratio of the seeds, but the dried beans absorbed moisture, so add 10% to the catechin solution on the way. The ratio was 1 to 1.1. After soaking for 3 hours, the beans were taken out, peeled off the seed coat that had become soft by sucking water and weighed, and the skin weight was about 5.6% of the whole. In the brown skin, only thin veins remained brown, and the entire skin was decolored and transparently visible. In the extraction solution, the color of yellowish brown green tea was changed to dark brown of dark oolong tea.

Extraction analysis of the active ingredient resveratrol to which attention was paid in peanut seed coat was performed by this extraction solution 1: 9 acetonitrile by high performance liquid chromatography analysis.
Resveratrol is believed to have heart disease prevention and anticancer effects, and is known to dissolve easily in boiling water and ethanol. In 2003, the University of California resveratrol in red peanut seed coats with red wine. Research has shown that Troll has the effect of delaying aging. (Internet materials)
Recently, a water-soaked extract of peanut seed coat has been patent-registered as an active ingredient of a hematopoietic recovery agent that exhibits bone marrow cell proliferation activity.
