Method for producing a dry flower type which does not change color by easily changing color flowers

The present invention relates to a method for producing a dried flower, and more particularly to a method for producing a dried flower which is characterized in that the undried flower is used as a dried flower, and the colorless flower is not discolored, and the dried flower is formed. By.

Conventionally, the flower, the leaf, the stem, and the like are dried, and the dried flower is dried by drying the original shape and the primary color to obtain a method for producing a dried flower. Substituting the organic solvent which is dried after dehydration, the dehydration method, the vacuum drying method of drying the undried flower under vacuum, the freeze-drying method of drying the undried flower after drying, embedding the undried flower in the desiccant, drying the flower The type of desiccant is buried and managed.

Among them, the flower-containing water is replaced by an organic solvent instead of an organic solvent, and the organic solvent is dried, and the dehydration method is used, and a dry flower having a rough color, a leaf color, a stem color, and a thick portion such as a leaf or a stem is obtained. Class, but replaced by the fact that the leaves or stems are easily whitened. In addition, there are also those who are easily whitened depending on the type of flowers. For example, the parts of the flowers such as the orchids are also whitened. For example, Patent Document 1 discloses a method for producing a dried flower-dried product by substituting and dehydrating flowers with an organic solvent such as butanol and/or propanol.

The vacuum drying method for drying flowers under vacuum is required to maintain the shape of the flower, that is, to embed sand or glass beads, or to cover the cloth, and to fix it by pins, etc., in the container. In the vacuum environment, the method of rapid drying, the flower type is dried by the latent heat of evaporation containing water, and dried in a frozen state.

The freeze-drying method of freezing the flowers and then drying the lyophilized method is more faithful to the original shape and the primary color except that the petal meat is easy to sag, but as the drying continues, the temperature of the drying chamber must be lowered, because otherwise, with the flowers The cell-like cells are gradually concentrated, and the flower shape and the like are gradually collapsed, so that a temperature of about -30 ° C is usually required. Therefore, the drying electrode takes a long time and the scale of the device becomes large. For example, Patent Document 2 discloses that when flowers are embedded in a granular form, dry air is sent to a flower or leaf in a range of a specific temperature and a specific time to be dried, and then freeze-dried.

Embedding flowers in a desiccant-dried desiccant, trying to separate the various parts of the flower, such as flowers and stems and leaves, although the color of the different parts of the tissue is relatively uniform, but it cannot be used. It is a disadvantage of flowers that are easy to change black, such as thin parts such as stems.

[Patent Document 2] Japanese Patent Publication No. 08-040801

The present invention relates to a method for producing a dried flower, and when the undried flower is used as a dried flower, the colorless flower is not discolored, and a dried flower having a primary shape and a primary color is directly obtained.

In order to solve the above problems, the inventors of the present invention have tried to repeat the results of the review and found that in the conventional method for manufacturing dried flowers, in order to prevent discoloration of easily-discolored flowers, a dry flower which directly retains the original shape and the original color is obtained, Before the method for producing a dried flower type, a specific treatment is carried out to obtain a dried flower which directly retains the original shape and the primary color, and the present invention has been completed.

That is, the present invention is

1. The immersed flower is taken out at 0 to 30 ° C for 10 seconds to 20 minutes, and then at least 1 is selected by substituting an organic solvent for dehydration, vacuum drying, freeze drying, and desiccant powder. a method for producing a dried flower type characterized by a drying method,

2. The method for producing a dried flower according to the above 1, wherein the flower type is selected from the group consisting of three-leaf yellow lotus, German lily of the valley, mountain pepper rose, gardenia, shrimp green, yellow root orchid, chicken vine, aconite, thorn, and dragon At least one of beads, safflower tobacco, sunken flowers, wild donkeys, or blue roses,

3. The method for producing a dried flower according to the above 1 or 2, wherein the flower is a blue rose,

4. The method for producing a dried flower according to the above 3, wherein the blue rose is a blue rose having a delphinidin derivative in the petal.

5. The dried flower obtained by the production method according to any one of the above 1 to 4,

6. A resin sealing article comprising a dried flower of the dried flower type as described in the above 5,

7. The resin sealing material according to the above 6, wherein the resin sealing material is a resin embedded product or a resin coated product.

According to the present invention, since the treatment with acetone is extremely short-time, the work is easy, and it is possible to obtain a dry flower such as a flower-like pigment or the like, a surface of which is not rough, and which does not impair the gloss or texture of an important characteristic of the flower.

The best form for implementing the invention

The invention is described in detail below.

The term "flowers" as used in the present invention refers to various parts of the plant body including flowers, leaves, stems and roots, and the whole.

In general, when the plant body is dried, the cells inside the plant tissue move with each other, but at this time, the enzyme that induces discoloration moves from the cells originally containing the pigment to the cells containing the substance that causes discoloration. The occurrence of discoloration is widely known. In this case, the term "discoloration" mainly refers to polyphenols which are usually caused by blackening, but discoloration into other colors other than blackening, that is, coloring can be made such that the flower originally has a color other than the color.

For example, the three-leaf yellow lotus has a flower with a pure white surface and a pale purple spot on the bottom, but the pure white portion of the surface is also reddish due to the usual dehydration and drying. In addition, the German lily of the valley (Western species lily of the valley) is any drying method, the flower handle is easy to turn black, but at the same time the red spot on the bottom of the petals. These are different types of discoloration caused by the movement of polyphenols on the surface portion of the flower during drying to cause discoloration of the color of the flower.

The above two cases are special cases, and there are many flowers that cause brownish brown discoloration during drying. Many drying methods have a step of preventing the discoloration from becoming brownish brown, and are embedded in a drying method such as drying of a drying agent such as a silicone powder. It is rapidly dried to solve the problem of preventing browning, but there are many kinds of flowers that cannot prevent discoloration by such a conventional drying method.

The flower-based discoloration of the following examples other than the above two types is listed.

The red pepper petals of the red peppers are colored brown.

Gardenia ‧ ‧ white petals with grayish black

Shrimp Ridge ‧ ‧ red brown and white, but the white part has dirty cyan markings.

Yellow roots ‧ ‧ yellow petals with black

The white black of the red tubular flower in the white center of the chicken vine.

The aconite ‧ ‧ ‧ blue purple flower part turned brown

The thorns ‧ ‧ ‧ red flowers turn brown

The white part of the red and white flower of the dragon spit ‧ ‧ black

Safflower tobacco ‧ red to black

Shen Dinghua ‧ ‧ is a reddish purple and white flower, but the white part becomes dirty black.

The wild ‧ ‧ ‧ red purple flowers and bright brown stalks, the flowers become brown, the handle turns black

Blue Rose ‧ ‧ petals with a distinct reddish brown color

The discoloration as described above exists in various species and genus of flowers, and the flower type of the present invention includes those plant bodies which cannot prevent discoloration by such a usual drying method.

Then, all of these systems cannot be prevented from discoloring by conventionally known drying methods. Although it is immersed in ethanol, immersed in formalin, or exposed to formaldehyde vapor, etc., only to prevent blackening, this is a method for producing a bleaching flower, and is not a method for retaining the primary color.

The acetone used in the flower-based immersion treatment in the present invention is generally used as a test reagent or an acetone used for industrial reagents.

Next, the acetone treatment used in the present invention is carried out using a flower freezing temperature or higher, usually at a temperature below room temperature, that is, acetone at 0 to 30 ° C, preferably 7 to 25 ° C, and preferably 10 to 20 ° C. The immersion treatment time is in the range of 10 seconds to 10 minutes, preferably 20 seconds to 7 minutes, and more preferably 30 seconds to 5 minutes.

The acetone temperature and the immersion time of the acetone treatment in the present invention vary depending on the type and size of the flower to be subjected to the object, but an appropriate and correct range can be obtained experimentally.

The acetone treatment according to the present invention is sufficient to use acetone at a normal temperature, and since the acetone is impregnated for a short period of time, the flower-like pigment is not lost at all, and the surface of the petals or the like is not rough, and the characteristics of the flower are not impaired. Significant flower luster or surface texture to achieve significant results.

Since the acetone used in the treatment of the present invention plays a role as an anesthetic, it is presumed that it is not used as a usual fixed drug. In other words, the general name is not limited to the plant body, and the animal body is made into a specimen, and the original shape and the primary color are equal to the living state, and the preservation and storage are fixed.

Next, when the acetone treatment of the present invention is observed, since it is far less than the immersion time in the common sense of the fixing agent in terms of the treatment time, it is presumed to play the role of an anesthetic agent. That is, although the effect of preventing discoloration is found, the fixing system continues the treatment and is completely fixed by drying, so that the obtained one becomes a dry flower which can be processed by other commercializations which continue the resin processing thereafter.

That is, the acetone treatment of the present invention is because the acetone has a very high permeability to plant tissues, and the function of a protein precipitant having an appropriate strength in acetone, so that although the enzyme activity of the plant is stopped by dipping for a short time, it does not The plant tissue itself is swollen or shrunk and destroyed, because it has been confirmed by experiments, so the flower plant body does not change color due to the enzyme activity, and the extent of the damage of the tissue surface does not occur, and the acetone impregnation is stopped. Then, a normal flower drying method or a dehydration method is carried out to obtain a dried product in which the surface state of the flower or the state of the original color and the living body hardly change.

For those who are suitable for this purpose, it may be feasible to use a rapid treatment agent for fixing. However, it has been found that it is extremely difficult to find an appropriate treatment agent. The inventors chose acetone as the treatment agent, and first found that the treatment was used. The agent confirms the effect and the effect.

In the rapid fixing, although the method of exposing flowers to a tannic acid atmosphere is considered, the price of tannic acid is extremely high, which is not a practical method, and it is not suitable for the purpose of discoloring the flowers into brown. The treatment method of the invention.

In addition, although a method of exposing flowers to a cyanic gas atmosphere is considered, since this treatment uses cyanic gas, it is an extremely harmful and extremely dangerous treatment to the human body, and it is not an easy method.

In addition, although picric acid also penetrates quickly and the fixation is not too intense, it cannot be used because it is a yellowish coloring agent.

Acetic acid is also fixed at a rapid rate, but because it is strong acid, of course, the color of the color is discolored, so it cannot be used.

The advantages of the treatment method of the present invention are not only rapid, inexpensive, but also very low in risk and toxicity, and easy to handle. Regarding the drying of flowers, only the flower portion is treated with acetone, and the whole flower is dried. When you get a dry flower, you can simply get it. That is to say, when drying flowers, the shape of the flower or the leaf is a matter of course, but at this time, the flower shape and the leaf shape are rebuilt by fine glass beads, etc., and the vacuum is dried or buried in the silicone powder. It is necessary to refine the shape and the like, but at this time, of course, the flowers or leaves in the original state of the flowers are easy to handle, because the black color or the flower color is discolored to a color other than the original color, and the flower is mainly used as the main body instead of In the case of leaves, the object of the present invention can be easily achieved by simply drying the entire portion of the flower after acetone.

In addition, the advantages of the treatment method of the present invention are rapid treatment, but too fast and difficult to control. When the immersion time is too long, the surface of the flower is rough, the texture is damaged, and when the treatment time is too short, it is difficult. The determination time, in addition, when processing a large number of flowers, the time difference between the first added flower and the last added flower also occurs, and at this time, an organic solvent having no fixing effect such as butanol or ethylene glycol may be added. Or an organic solvent such as isopropyl alcohol, which has a weak fixing effect, reduces the acetone concentration and prolongs the treatment time.

For example, the treatment of three-leaf yellow lotus and the like may be carried out for 30 to 40 seconds, and when the same amount or multiple amounts of ethylene glycol as acetone is added, the treatment time may be extended to the extent of 2 minutes to 10 minutes.

In addition, in the case of blue roses, the appropriate correct treatment time is from 4 minutes to 8 minutes, and when an equal amount or a multiple amount of butanol is added to acetone, it may be from 15 minutes to 30 minutes. However, when acetone is used alone or when diluted, if the immersion is too long, the texture of the flower is of course impaired, and the pigment of the flower flows out depending on the situation. Therefore, the immersion time of the acetone varies depending on the temperature or the variety of the flower, and even The same flower is still different depending on the period or state of growth, but the above range is approximate and can be determined according to the experiment at that time.

The dried flower of the present invention thus obtained can be used as it is for viewing or the like, but it is preferably a resin seal. Since the dried flower type of the present invention is dried without discoloration, it can be suitably used as a material for a resin seal. A resin seal is a form that is sealed by a resin and does not directly contact the air. As the resin seal, for example, a resin-embedded product or a resin-coated product can be mentioned. The resin-embedded product or the resin-coated film has an excellent strength surface as compared with a dry flower, and is further improved in the stability surface at the time of storage.

The resin to be used for the resin sealing material is preferably a transparent resin, and examples thereof include an acrylic resin, a polyester resin, a polyurethane resin, an epoxy resin, a silicone resin, and the like, and these may be used singly or in plural. From the viewpoint of gas barrier properties or preservation stability of flowers, etc., it can be appropriately selected from these. Among them, an acrylic resin excellent in workability or stability is suitable. If necessary, a hardener may be mixed for use with these resins.

The resin seal of the present invention of the resin-embedded product or the resin-coated film can be produced by a known method. Among them, the resin-embedded article can be produced, for example, from a resin filled in a suitable size and a dried flower. The size of the resin-embedded article is not particularly limited. In addition, the shape may be a cube, a rectangular parallelepiped, a hemisphere, or the like.

Further, the resin film product can be obtained by drying the surface of the flower and drying the coating resin. Although the thickness of the film is not particularly limited, it is usually in the range of 10 μm to 1000 μm, and more preferably in the range of 50 to 500 μm.

The resin seal of the present invention of such resin-embedded articles or resin-coated films can be used as a specimen, an exhibit or an ornament.

Further, a blue rose can be cited as one of the flower types to which the technology of the present invention can be applied. In the present invention, the term "blue rose" refers to a rose which accumulates a cyan pigment (delphin derivative) such as delphinidin in a petal. Such a rose can be obtained by, for example, the method of Japanese Laid-Open Patent Publication No. 2005-017147. Since the blue rose is easily discolored or deformed by the conventional dry flower manufacturing method, the manufacturing method of the present invention can be suitably used. Further, the blue rose can also be suitably used as a material of the resin seal of the present invention which is a resin-embedded product or a resin-coated product in a form in which the color is not easily changed.

[Examples]

Hereinafter, the present invention will be specifically described using examples and comparative examples, but the present invention is not limited to the examples and the like.

[Example 1] [三叶黄莲]

Cut the ground part, place it on the bottom of the mesh box with thin cotton wool, and cover with other cotton-like absorbent cotton from the top. Insert the needle into the key part and finish it to avoid the shape collapse. After sinking into acetone at 10 ° C, the whole was immersed in the state of acetone, and after 30 seconds, it was taken out, and after the acetone was flowed down, it was immediately placed in tert-butanol. The flowering period of the yellow-leaved yellow lotus is in the winter, because the tert-butyl alcohol freezes at room temperature in the winter, so a small amount of water is added, and it is adjusted to a liquid state in advance, and after being placed in the butanol, the dehydration is replaced by 2 hours. After the end, the covered cotton wool was removed, and the dehydrated and hardened trifolium repens were taken out, and dried under an infrared lamp to obtain a dried three-leaf yellow lotus. When the dried flower is formed by the dehydration method of the usual isopropanol or butanol, the white petal has a reddish purple marking, but the dried flower obtained does not have such a reddish purple streak.

[Embodiment 2] [山椒蔷薇]

Cut the branches of the flowered rosemary into the desired length. Usually, the flower is flowered at the top part of the stem, but the flower is opened at the top and side. The top part of the flowerer is to put the branches upside down, so that only the top part of the flower is immersed in acetone at 15 °C. Only immerse the flower part as much as possible. Because the pigment in the leaves is small, it has a sputum. When the branches of many flowers are opened, only the flower portion is cut and placed in acetone. At this point, after the end of drying, the flowers are adhered to the dried branches. The immersion time of the flowers for ice-cold acetone was 2 minutes. Thereafter, a usual three-dimensional embossing drying method is applied. That is, the whole was embedded in the silicone powder, stored in a closed container, and left for about 2 days, and then taken out. Both the cut flower and the leaf are buried separately and adhered after drying.

As another drying method, a vacuum drying method or a butanol-substituted dehydration method can also be applied, but the results of any method are not greatly different. The person who dries without acetone is dry on the surface of the flower with a brownish brown color, which is not good, but it is not the case when it is treated with acetone.

[Example 3] [Shrimp Ridge]

The flowering branches were cut out, immersed in acetone at 10 ° C for 5 minutes, and then taken out and then quietly embedded in fine glass beads. Because flowers become more fragile than when they are alive, they need to be carefully watched. Thereafter, it was vacuum dried. The vacuum was maintained at several times Pascal for 24 hours and dried. If the shrimp ridge is only dry, it forms a dirty cyan marking on the white part of the flower core, but it can prevent it from happening.

[Example 4]

When the shrimp ridge is buried in the silicone powder for drying, the yellow petals are black, but after immersing in acetone at 10 ° C for 5 minutes, the silicone resin is not discolored when dried.

[Example 5]

When the gardenia is dried by substituting dehydration with a usual organic solvent, the white petals are dark brown, but after being immersed in acetone at 13 ° C for 6 to 7 minutes, the organic solvent is used instead of dehydration and dried to prevent discoloration.

[Embodiment 6]

When aconite was dehydrated and dried by butanol, the cyan purple petals were discolored to have a black-brown color, but after being immersed in acetone at 15 ° C for 3 minutes, the dehydrated drying did not cause discoloration.

[Embodiment 7] [沈丁花]

The twigs were cut out, and the whole was immersed in acetone at 12 ° C for 20 to 30 seconds, and then taken out, and the silicone powder was embedded. If it is taken out after 4 to 5 days, a dry flower of primary color can be obtained. The white portion of the flower directly embedded in the silicone powder without acetone treatment is black, and the red portion is brown, but the above-mentioned acetone is applied to prevent the discoloration. Further, if the immersion time is too short and it is difficult to adjust the time, an equal amount to twice the amount of butanol may be added, and the treatment time is extended by 4 times to 10 times or more. The surface of the flower is white and the bottom surface is dark red. However, if the immersion time is too long, the flower is slightly transparent, and the red color of the bottom surface is reflected on the surface. If it is too short, the white portion will be black. It is most suitable for the time when the white part is slightly transparent, and the color of the red part is not faded. However, it is convenient to confirm the time sufficiently to extend the time in advance.

[Embodiment 8] [blue Rose]

The flower was immersed in acetone at 15 ° C for 5 to 6 minutes, and then taken out and immersed in butanol for 2 to 3 hours to complete dehydration. This flower is very easy to become a brown flower. When making a dry flower, the petals are easily discolored into a reddish-brown color. In particular, the joint portion is highly discolored, so special care must be taken when immersing, and when excessively immersed, the petals are rough and the texture is impaired. To prevent this, add an equal amount to twice the amount of butanol in acetone, extend the immersion time, take it out at regular intervals, and observe the roughness of the surface with a magnifying glass. Once the surface is considered to be slightly rough, remove it immediately and enter the dehydration step. .

[Embodiment 9]

A resin seal was produced using the dried blue rose obtained in Example 8. The portion of the dried blue rose obtained in Example 8 was cut, and the portion of the stem having a flower of about 5 mm was placed in a container placed together with the acrylic resin to which the curing agent was placed, and allowed to stand and harden to obtain about 10 cm on one side. Acrylic resin seals.

[Embodiment 10]

A dried resin product of the blue rose obtained in Example 8 was used to produce a resin film. The dried blue rose obtained in Example 8 was cured by coating a transparent acrylic resin coating on the entire surface to obtain an acrylic resin film having an average thickness of about 100 μm.

Industrial use

The present invention can be utilized in the field of drying flowers and the production of dry flowers.
