Description

Plum extract

  The present invention immerses plum fruit in a water extract or squeezed solution of fresh leaves of snow willow or kodemari, a supernatant liquid or squeezed liquid obtained by crushing fresh leaves of snow willow or kodemari together with water, or an aging liquid thereof. This relates to a non-alcoholic plum wine-like plum extract.

Currently, non-alcoholic beer is known, but there is no non-alcoholic plum wine. The present invention provides a plum extract that can be said to be a non-alcoholic plum wine. Meanwhile, conventionally, as a disinfectant or preservative, food and medicine, depending on the processing object, such as planting培植product, it has material from various chemicals and plants are used. However, recently, foods that are used by human beings, foods around kitchens, and those used on the skin are becoming popular because they are derived from natural products such as plants from the viewpoint of safety. And this invention manufactures a plum extract using the liquid derived from natural products, such as the extract of a snowy willow or Kodemari fresh leaves.

  Plants produce more or less bactericidal and antiseptic substances in their tissues for self-protection. For example, Patent Document 1 shows that 64 kinds of plant extracts have antibacterial and antiseptic properties. In addition, red perilla (JP 2002-000245), Inuco genus (JP 2001-342106), Maple genus (JP 2002-029925), rosemary extract (JP 2002-088395), dokudami, coriander, neem, etc. Many plant extracts are said to exhibit bactericidal and antiseptic properties.

  On the other hand, for deodorization, essential oils such as orange oil, lemon oil, and peppermint oil (Japanese Patent Laid-Open No. 5-146495), plant essential oils such as camphoraceae (Japanese Patent Laid-Open No. 5-161697), and various dried herbs are effective. It is said. The deodorization mechanism includes physical adsorption, chemical decomposition, and masking, but the deodorization of plant essential oil is said to be due to chemical decomposition or masking.

  As described above, many plant extracts and essential oils have been proposed as fungicides, preservatives, and deodorants, but some of them are not effective enough, and in the case of essential oils, the production cost is high. There are drawbacks.

  Therefore, the present inventor has obtained an extract of water from various plants that are close to him, and while conducting various tests, the Spirae plant extract exhibits excellent deodorant antibacterial and antiseptic properties, and penetrates. The present invention has been completed by finding out that the power and extraction power are very strong.

  Originally, the present inventor tried water extract solutions of various plants for the purpose of preventing cabbage for spawning eggs for spawning, that is, for the repellent effect, and several kinds of plants showed the repellent effect. However, the water extract of most plants began to grow moldy or rot and began to give off an unpleasant odor, but the only change was not seen in the snowy willow.

  Moreover, the water extract of snow willow has been found to be difficult to evaporate even if left in a beaker and left in the sun. Therefore, when an appropriate amount of the extract was dropped on the iron plate and allowed to stand in the same manner, the viscosity increased with the evaporation of water, and finally it became a water tank. It took about 1 to 2 days for the chickenpox to appear. This elutriate material quickly dissolved in water. In addition, this varicella-like substance showed deliquescence that softens by absorbing moisture when it is humid, such as on rainy days.

  In addition, beakers and moths do not stick around the beaker containing this water extract, rice or fresh confectionery sprinkled with this solution, and there will be no ants around the spilled liquid. I noticed. Moreover, rice and fresh confectionery did not rot even after a year or more at room temperature. This means that the substance contained in the fresh leaves of snow willow has the action of suppressing the evaporation of water, the repellent action of insects and the like, and the antibacterial and antiseptic action. The same was true for other plants belonging to the genus Spirae, including not only snowy willows, but also Kodemari, mochi and shijimi. However, the substance is not specified at present. It is also unclear whether it is a single substance or a synergistic effect of multiple substances.

  Snowy willows, kodemari, shishisuke, shijimi flowers, etc. are widely distributed in Japan as wild or garden trees. However, these have no other uses other than loving the flowers themselves as garden trees or flower arrangements, and there is no description in the medicinal plant dictionary. As far as the present inventor is aware, it has not been known at all that these plant extracts have insect repellent effects. Moreover, it has not been known at all to produce plum wine-like beverages by immersing plum fruits in this extract. However, it has been found that the willow will contain antibacterial substances (Patent Documents 2 and 3).

  However, these antibacterial components are obtained by extracting fresh leaves, stems, fruits or flowers of Spirae plants with ethanol or butanol and then eluting and concentrating with ethyl acetate-benzene. Not included. However, since the water extract has an antibacterial effect as well, in the case of the water extract, substances described in Patent Document 2 and Patent Document 3 (β-hydroxy-α-methylene-γ-butyrolactone, β, γ-dihydroxy) are used. It is considered that an antibacterial component different from (α-methylenebutyric acid ester) is contained.

On the other hand, raw garbage and fish and shellfish produce rot odor because they are decomposed into bacteria to produce malodorous gases such as ammonia, trimethylamine, methyl mercaptan, and hydrogen sulfide. Therefore, if the activity of bacteria is suppressed with an antibacterial agent or the like, the generation of odor gas after that can be suppressed, but the odor gas so far will remain as it is. However, in the case of the extract of the present invention, when it is sprayed on fish and shellfish having a rotting odor, the rotting odor disappears immediately afterwards, and only the natural odor (raw odor) originally possessed by the fish and shellfish is obtained. Of course, no foul odors occur at all in the days after spraying. The amount of spray should be increased depending on the degree of spoilage. For prevention, it is more preferable to spray before rotting. The extract of the present invention has an excellent effect especially on hydrogen sulfide (rot odor of mussel shellfish). The extract of the present invention does not bromide only the malodorous gas, and cannot treat the raw odor of seafood, the garlic odor, the citrus odor, and the like.

JP 2003-1113013 A Japanese Patent Laid-Open No. 50-24423 Japanese Patent Laid-Open No. 50-24424

  Further, the extract of the present invention can be used for deodorization and antibacterial of various bad odor sources such as deodorization and antibacterial preservation of garbage, kitchen and kitchen, and kennel. In addition, spraying foods such as ginger and confectionery as an antifungal agent, or dropping a few drops onto milk, raw yogurt, amazake, etc., has the effect of preventing deterioration for several days even at room temperature. In addition, since this extract is also rich in plant fibers rich in minerals such as Ca, K, Mn, Na, P, and Zn, it can be used as a food additive.

  Providing a non-alcoholic plum extract that shows the appearance, taste and smell of plum wine sockri.

  Hereinafter, the present invention will be described by taking the case of a willow as an example. The snowy willow is also called Kogomebana, and in March and April, it blooms together with white flowers and blooms. The stem is standing and has a height of 1 to 3 m. The leaves gradually darken green and gradually turn yellow after fall.

  Initially, the present inventor collected fresh leaves and flowers of snow willow, pulverized with a mixer with water, and used the supernatant for experiments, but the effect of simply immersing in water for several days was considerably inferior, Deodorant antibacterial and antiseptic effect was observed. Also, fresh leaves and flowers boiled in water, and those obtained by heating and concentrating the supernatant liquid showed some repellent effect. Moreover, the liquid obtained by crushing (mixing with water) is separated into a supernatant liquid and a fiber after 1 to several days (the latter is settled). In about one month, the supernatant liquid becomes transparent brown (so-called whiskey color).

  This supernatant liquid is initially light brown and smells blue, but as it matures (about a month), it becomes a dark transparent brown color, and the smell is peculiar to a mixture of plum wine and shiso from a smell like shiso Shows fragrance. In this state, there will be no corruption even after 3 years. The effect of deodorizing antibacterial and antiseptic gradually becomes stronger from about one month. Such a change is presumed to be caused by some chemical change or by the action of an enzyme. The taste also changes, but some feel astringency and bitterness. The pH of the supernatant liquid is initially about 5.7 to 5.8, but gradually decreases and becomes about 4.4 to 4.5 after 6 months.

  In addition, when a supernatant liquid evaporates water, a small amount of viscous solution remains on the bottom of the container. This solution smells similar to the supernatant and returns to the original supernatant when water is added. This solution and the returned supernatant also show a deodorizing antibacterial and antiseptic effect. From this, it can be seen that the plant extract of the present invention has a moisturizing effect or an effect of encapsulating a chemical substance.

  On the other hand, deodorant antibacterial and antiseptic effects equivalent to those of the supernatant liquid are also observed in the residue after removing the supernatant liquid. Therefore, if this cocoon is placed in a dish or the like and placed in the refrigerator or in the corner of the room, it has a deodorizing antibacterial and antiseptic effect and an insecticidal effect.

  The part of the snow willow used may be any of leaves, flowers, branches, stems or roots, but leaves, especially fresh fresh leaves, are most preferred for the plum extract. It also has a great deodorizing and antibacterial effect. In the case of using a mixer, water is used in the range of 100 to 1000 cc with respect to 50 g of fresh leaves (water washed and drained). When the amount of water is small, the mixer is difficult to rotate. When the amount is too large, the deodorizing antibacterial and antiseptic effect may be deteriorated and the liquid may be moldy. Preferably, it is up to 500 cc of water, especially about 200 to 300 cc with respect to 50 g of fresh leaves.

  On the other hand, the ripened supernatant (extract) does not spoil or mold at all even if it is stored at room temperature without covering the container. In addition, as described above, the extract smells of faint plants such as plum fruit and shiso leaves. If you are worried about this smell, put it in a blender with a small amount of bay leaves, mint or other herbs, or add a small amount of aromatic plant extracts or extracts such as herbs. No longer care.

  The processed product of the extract means a product obtained by concentrating, diluting, purifying, or powdering the extract. Concentration refers to reducing the moisture by heating the extract, but may be performed under reduced pressure in order to avoid the influence of the heat of the components. Dilution can be performed with water or alcohol at an arbitrary ratio, but the deodorizing antibacterial and antiseptic effects are inferior. Moreover, since normal hot-air drying is difficult, powdering is good to vacuum-dry an extract. These processes are selected according to the application.

  In addition to the deodorizing and antibacterial antiseptic effects, this extract has a repellent effect that keeps insects such as mosquitoes, flies and small flies away. In addition to insects, small animals such as moths, grasshoppers, slugs, etc., commonly referred to as worms (these insects and small animals are also referred to as hygiene pests, unpleasant pests, etc.) It disappears as soon as possible. Therefore, even if kitchen garbage is stored in a state where the extract is sprayed, there is no rot odor for several days, and it is not hygienic because it does not attract firewood or small jars. . It is also possible to use a mixture of some insecticide components in this extract or its processed product. In this case, the mixture also has an insecticidal effect.

  In addition, a characteristic of this extract is that it has very strong penetrating power and extracting power. For example, if you pickle plum fruits, you can make a plum-like taste. The color of the liquid is originally brown and looks like an old plum wine, so the appearance and taste are plum wine itself. It just doesn't contain alcohol. Now, people who are not good at alcohol and children can enjoy the taste of plum wine. The method of making is the same as that of umeshu. Simply put 1 kg of plum fruit and 1 kg of sugar sugar in 1.8 L of the extract and leave it to stand. After 3 months, it will taste like plum wine. As it gets older, it tastes even more. Even if this extract is diluted to about 10 times, there is no risk of spoilage. Next, mekabu (wakame sprouts) is said to have the effect of a herbal medicine, but when mechabu is chopped and soaked in water, it becomes sticky and very difficult to handle. However, when a mechab is attached to this extract, it is strange that no stickiness can be formed at all and a smooth solution is obtained. Furthermore, when chestnuts and acorns are soaked in the extract, they penetrate to the inside fruit, and when the skin is peeled and the inside fruit is immersed in water, the water shows the same color and odor as the original extract.

  Examples of plants excellent in antibacterial and antiseptic properties that can be used in combination with the snow willow of the present application include thyme, sage, comfrey, laurel, walrus, eucalyptus, tea tree, red perilla, dokudami, and neem. These are mixed with snow willow and pulverized with a mixer, or extracted alone and then mixed with an extract of snow willow and the like. These fresh leaves are used at a ratio of 40% or less, preferably 30% or less. If it exceeds 40%, the extract may be spoiled or moldy. The extract of fresh leaves of spirae plants such as snow willow will never rot or mold. In addition, it has a strong extraction power and is highly moisturizing, and has the effect of sufficiently extracting and stably storing the active ingredients of the leaves of the plants used in combination. In addition, a small amount of fragrant plants (such as leaves) such as herbs may be added or crushed together, or a small amount of an extract, extract or perfume of aromatic plants such as herbs may be added. Depending on the application, chemicals with deodorizing and antibacterial effects may be added.

  As described above, the present invention is a plum extract obtained by immersing plum fruit in a solution containing a leaf, flower, branch, stem, or root extract as an active ingredient.

Accordingly, the following effects can be obtained.
(1) The plum extract of the present invention can have an appearance, taste and smell of plum wine sock, only without alcohol. In addition, extracts such as leaves of Spirae plants themselves have a deodorizing antibacterial and antiseptic effect, and do not deteriorate even after a long time.
(2) Extracts such as leaves of the genus Spirae are obtained from natural plants, unlike chemical products, and because they are extracted only with water, they are very safe. In the example of the mouse of Example 6, in the case of a person of 50 kg, even 1 L is safe so that there is no acute toxicity. Usually, umeshu is enough to drink about 1 cup to half of a cup at a time, so there is no problem with these charges.
(3) Extracts such as leaves of the genus Spirae are extracted with 100% water, and therefore contain only those that are soluble in water, and are environmentally friendly.
(4) The extract of the leaves of the genus Spirae used in the present invention itself has antibacterial properties, so it does not require the addition of synthetic chemicals or the like, and has no toxic effect for a long time. But there is no problem at all. In addition, it is safe to spray near foods such as kitchens.
(5) Plants of the genus Subira, including snowy willows, kodemari, moisturizing, and shijimi flowers, are widely found in the wild and garden trees. The flowers are beautiful and good for beautification of the environment. It grows fast, is effortless, and is available in large quantities at a low price.
(6) Since the extract of the leaves of the genus Spirae used in the present invention can be easily obtained with a simple operation and apparatus, the processing cost is low.
(7) Since the extract of the leaves of the genus Spirae is water, the cost is very low and the extraction operation can be performed easily and safely. The reaction is suppressed and a product having excellent safety can be obtained.
(8) Extracts such as leaves of Spirae plants do not rot or discolor for several years (currently 3 years), and also maintain a deodorizing antibacterial and antiseptic effect.

  The fresh leaves of snow willow are washed well with water, then filled into a domestic mixer, poured into water, pulverized and stirred for 3 to 5 minutes with the mixer. This is transferred to a container and allowed to stand for 1 to several days for solid-liquid separation. When the fiber is lifted, stir. In January, a clear brown liquid was obtained. This solution exhibits an excellent deodorizing antibacterial and antiseptic effect for seafood and raw garbage. In particular, it becomes a very transparent solution with a unique odor and reddish brown taste similar to plum wine for more than a month, and has an excellent deodorizing antibacterial and antiseptic effect. Strangely, the freshly made solution has almost no deodorant antibacterial and antiseptic and insect repellent effects. When one month has passed and it begins to smell transparent and has a unique odor, an antibacterial and antibacterial effect and an insect repellent effect are produced. More than half a year will be more effective. Although this inventor preserve | saved the thing more than three years ago, the deodorizing antibacterial preservative effect and repellent effect are completely the same. This is presumed to be a result of some activity of some enzymes working with water. Then, the plum fruit is soaked in a liquid that has been more than one month old. Originally, this liquid itself is a very transparent solution with a unique smell and reddish brown taste similar to plum wine, so that the taste and smell of plums are further emphasized by soaking plum fruits.

(Production method 1)
Hereinafter, the present invention will be described in more detail with reference to examples. First, 50 g of fresh fresh leaves of snow willow are thoroughly washed with water, then filled in a home mixer, poured with 300 g of water, and crushed and stirred with a mixer for 3 to 5 minutes. This is transferred to a container and allowed to stand for 1 to several days for solid-liquid separation. When the fiber is lifted, stir. Although it smells like green leaves, it becomes a clear solution with a whiskey-like reddish brown color after a month. This solution smells like plum fruit liquor. When 300 cc of the supernatant liquid was allowed to stand for several days was taken in a bottle and left in the sun from May to June, it decreased to about 270 cc in January. In addition, in crushing with a mixer, water is used in an amount of 100 to 500 cc, more preferably 200 to 300 cc, based on 50 g of fresh leaves (washed and drained). In the case of squeezed juice, a highly concentrated liquid is obtained.

(Manufacturing method 2)
A fresh solution of both the willow flowers and the leaves of Kodemari was treated separately in the same manner as in Example 1 to obtain a transparent solution. The former had less odor than the case of Example 1 even after one month had passed, and the deodorizing antibacterial and antiseptic effects were inferior. The latter had a similar odor after 1 month but a slightly different metallic odor, but the effect was equal to or greater than that of Example 1. In addition, when using a branch, there will be many wrinkles and it will become easy to grow mold.

(Manufacturing method 3)
After thoroughly washing 200 g of fresh leaves of snow willow, it was put in a pan with 1 L of water, boiled and then boiled over low heat. The fire was turned off when the amount of water was about 2/3. The soup stock had a deep reddish brown color than the color after 1 month in Example 1. The deodorizing antibacterial and antiseptic effect is about the same as that of the snow willow flower of Example 2.

(Manufacturing method 4)
Three drops of herb perfume were added to 50 cc of the solution obtained in Example 1 and stirred. When this solution was sprayed on clothes, the smell of perfume remained even after one week.

(Manufacturing method 5)
In Example 1, 10 g of fresh laurel leaves were added to 50 g of fresh leaves of snow willow and treated in the same manner. The obtained solution showed the same deodorizing antibacterial and antiseptic effect as that of Example 1. Similarly, a liquid having a deodorizing antibacterial and antiseptic effect was obtained when 10 g of fresh leaves of Dokudami were added.

(Safety confirmation 1)
(Acute oral toxicity test using male and female mice-Limit test-: Report of December 12, 2003, Japan Food Analysis Center)
Summary: The sample-administered group was given a 20 ml / Kg sample (pest repellent of the present invention: obtained in Example 1), and the control group was given a single oral dose of water for injection to male and female mice for 14 days. Observations were made. As a result, no abnormalities or deaths were observed during the observation period (November 20 to December 12, 2003). Therefore, it is considered that the LD50 value by single oral administration in the mouse of the specimen is 20 ml / Kg or more for both males and females.

The results of measuring the body weight of the mice before and after administration are shown in Table 1 (male) and Table 2 (female). There was no difference between males and females compared to the control group. In addition, the presence or absence of formaldehyde was examined by the same analysis organization (acetylacetone absorptiometry), but was not detected (detection limit: 5 ppm).

(Safety confirmation 2)
A small amount of the solution obtained in Example 1 (after 1 month) was placed in a wide-mouth bottle, and two cochleas were placed and the behavior was observed. She was alive after more than a month. During that time, no food was fed. In addition, even after several days after attaching to the human body, there was no abnormality in the skin. Moreover, there was no insecticidal effect even when sprayed directly on green caterpillars, ants, moths and the like.

(Manufacture of plum extract)
Pour 1 kg of plum fruit and 1 kg of icing sugar into 1.8 L of the solution obtained in Example 1 (after one month has passed) and leave it to stand. After 3 months, it will taste like plum wine. As it gets older, it tastes even more. Even if this extract is diluted to about 10 times, there is no risk of spoilage. This is because the extract has very strong penetrating power and extractability, so if you pickle the plums, you can make them taste like plum wine. The color of the extract is originally brown and looks like an old plum wine, so the appearance and taste are plum wine itself. It just doesn't contain alcohol. This plum soak can be enjoyed by people who are not good at alcohol and children.

(Confirmation of deodorant antibacterial and antiseptic effect 1)
Place the visceral viscera and 60g of fresh fish into a plastic container with two upper openings, A and B, respectively. The viscera and skin of the container A are directly sprayed three times with the solution obtained in Example 1 diluted with water (solution spray) three times, and the viscera and skin of the container B are left as they are (untreated). I watched the progress. The results are shown in Table 3. The experiment was conducted in the winter season (January 22 to 31, 2004, room temperature 8 to 18 ° C.), but the untreated (container B) started to odor from the second day. On the other hand, in the solution spray (container A), the scent of fresh fresh fish was maintained without rot smell until the sixth day. In addition, the number of fly flies gradually increased from 2 to 3 for the untreated ones, but none of the flies sprayed with the solution sprayed.

(Confirmation of deodorant antibacterial and antiseptic effect 2)
20g of fresh fish (squid) internal organs are placed in two upper open containers A and B in the same manner as in Example 7. The internal container of B is left as it is (untreated), and the internal organs of A container are sprayed three times in the same manner. I saw the progress. The results are shown in Table 4. In the case of this example, the solution spray did not have a rotting odor until the 9th day, but the odor of rotting started from the 5th day without treatment. The behavior of the fly was the same as in the previous example.

(Confirmation of anti-odor and antiseptic effect 3)
Using the solution of the present invention obtained in Example 2 (Kodemari leaves), the deodorizing and antibacterial antiseptic test of cotton tofu was conducted in the same manner as in Example 8. Four pieces of 10 g of cotton tofu are put into three 100 cc mayonnaise bottles, and the tofu in container A is sprayed with the solution three times in the same manner as in Example 8; The process was observed in the same manner. The results are shown in Table 5. In the case of this example, the solution spray did not have a rot odor until the 9th day, but a rot odor started from the 2nd day without treatment. In addition, mold started to grow in the container C from the fifth day.

(Confirmation of deodorant antibacterial and antiseptic effect 4)
In the winter season (around 15 ° C. in the room), the solution obtained in Example 5 (Laurel tree) was sprayed on the outer surface of the freshly picked round gourd. Mold did not grow even after 10 days. On the other hand, molds that did not spray the solution began to grow from about 5 days later. In addition, in summer (around 25 ° C indoors), about 3 drops of the same solution was dripped into each of raw yogurt, milk, and amazake in a glass. I kept it. On the other hand, a cup of yogurt without a solution showed a sour smell and taste after 2 days.

(Antimicrobial test)
Using the solution of Example 1 (test product), an antibacterial activity test against Legionella was performed by the diffusion method (qualitative disc method) using an agar medium (Japan Food Ecology Research Institute).
(1) Test method [Test strain] An ATCC standard strain of Legionella pneumophila was used.
[Used medium] BCYE-α agar medium.
[Adjustment of Bacterial Solution] Culture bacteria grown and grown on a BCYE-α agar medium for 24 hours were adjusted to about 106 / ml.
[Preparation of test product] The test product is diluted serially with sterile physiological saline (stock solution, 2-fold dilution, 4-fold dilution).
[Test method] Qualitative method (disc method): Each strain is smeared on an agar plate medium (1 platinum ear of 106 / ml of bacterial solution), and a disc soaked with a certain amount of the test product is used as a culture medium. Determine whether or not there is a growth-inhibiting circle around the filter paper after culturing at 37 ° C. for 5 days.
[Test subject] Sterile saline.
(2) Number of days required for testing 1) Preparation and preliminary testing 7-10 days
2) Main test, judgment 6 to 10 days (3) Test results As shown in Table 5, the stock solution showed an antibacterial effect against Legionella, but it was not found in the 2-fold diluted solution and 4-fold diluted solution.

(Experimental deodorization confirmation experiment of garbage)
From July 14th to August 31st, 2004, an experiment for confirming the deodorizing effect of 100 people was performed.
(1) Experimental method For each of 108 residents in a certain region, 250 cc of the solution obtained in Example 1 was put into a 500 cc spray container, and sprayed 2-3 times each time when garbage was put into a plastic bag. And asked to ask. As the solution, a solution manufactured in May 2003 (50 people) and a solution manufactured in May 2016 (58 people) were used. In addition, for the solution manufactured for 15 years, we also requested confirmation of the repellent effect against insects such as mosquitoes and flies.
(2) Experimental results After the experiment was completed, questionnaires were collected in mid-September 2016. The questionnaire results are shown in Table 7 (questionnaire recovery rate), Table 8 (odor of the solution itself), Table 9 (deodorization effect of garbage), and Table 10 (hope to continue in the future). In Table 9, 58% of the respondents said that the garbage had a sufficient deodorizing effect, 41% of the respondents said that there was a little, and 99% recognized the effect. The questionnaire collection rate was 72%. This seems to be due to the limited submission date. Among them, three people (4%) answered that spraying was troublesome. In addition, there were four people who wrote in the questionnaire free column that it was less effective for the bad smell of seafood. This seems to be because they mixed the raw and bad smells. As shown in Examples 8 to 10, the malodor removing ability is sufficient. If the amount of garbage is large, the problem can be solved by increasing the number of sprays and the amount of spray. In addition, there were a total of 18 people who wrote that fly flies and moths were no longer in the garbage in the questionnaire, and 18 people who wrote that mosquitoes, caterpillars, and rubber bugs were gone (15-year manufactured products were given and responses were received). Of 33 people).

  The umeshu-like extract of the present invention can easily obtain a non-alcoholic umeshu-like beverage simply by immersing plum fruits in an aqueous extract of leaves of plants of the genus Suebira such as snow willow. And since the liquid that soaks the plum fruit is extracted with water only, the safety is very high, and the plants of the genus Suvera such as snow willow are widely found in the wild and garden trees, and also for cultivation in Zantan It is also suitable, grows quickly, is untouched, and is available in large quantities at a low price. Moreover, since it can be easily obtained with simple operations and equipment, the processing cost is low.
