Description

Liquefied composition for plant preservation and method for treating using the same}

The present invention relates to a liquid composition for preserving a plant as it is by liquid treatment, and more particularly, for preserving a plant that can be preserved for a long time while maintaining a vivid natural texture of a plant prototype such as cut flowers (flowers cut for ikebana). It relates to a liquid composition and a method for treating plants.

It has often been proposed for a plant preservation solution in which water in a plant tissue is replaced with a liquid of a composition containing polyethylene glycol or glycerin.

Japanese Laid-Open Patent Publication No. 4-505766 discloses a method of allowing cut flowers such as roses (flowers cut for ikebana) to be preserved over a long period of time while retaining the appearance of flowers.

In the treatment method of the present invention, after dehydration of water in cut cell tissue, that is, tissue water, the tissue water is replaced with a composition liquid containing polyethylene glycol, and staining is performed as necessary. By processing the drying step and the drying step sequentially, the cut flower as a product which preserves the appearance such as fresh flowers can be obtained.

However, when the tissue of the plant substituted by the composition mainly composed of polyethylene glycol as described above has a predetermined humidity or more, there is a problem that the shelf life of the plant is significantly shortened by absorbing moisture in the air.

In addition, the cut flower substituted with the mixture of the polyethyleneglycol 400 and the polyethyleneglycol 1000 of the present invention is that the natural texture is remarkably lost, and the texture has a problem of being close to the harmony made of plastic.

In order to solve this problem, the Republic of Korea Patent No. 512585 discloses a liquid composition for plant preservation to increase the shelf life of plants by not absorbing moisture in the atmosphere above a certain humidity bar 100% ethyl alcohol in one step After the dehydration and decolorization process in two steps to precipitate in the liquid composition according to the comparative example, the comparative example of the liquid composition is shown in the table below.

In Table 1, PEG 200 is polyethylene glycol having an average molecular weight of 200, PEG 600 is polyethylene glycol having an average molecular weight of 600, PEG 800 is polyethylene glycol having an average molecular weight of 800. PPG 400 is polypropylene glycol having an average molecular weight of 400, and POPG 400 is polyoxypropylene glycol having an average molecular weight of 400. PPG 2000 is polypropylene glycol having an average molecular weight of 2000, and POPG 2000 is polyoxypropylene glycol having an average molecular weight of 2000. In addition, ethyl alcohol was used as C1-C3 alcohol.

As shown in Table 1, the flowers treated with the compositions of Comparative Examples 1 to 12, which occupy a certain range of composition ratios in the ternary system, have a long life because stains do not occur on the petals, and the petals have a natural and soft texture. However, when the flowers treated with the composition as described above are used again as a flower basket, such as severe debris, and the finished product than the initial state at the time of flowering (cut flowers) had a problem that the contraction is severe to prevent the circular preservation.

When the initial state of the flower is 100%, Table 2 represents the degree of shrinkage of the resultant in terms of the length and length of the resultant shrinkage in%, and the smaller the value, the degree of shrinkage (deformation) Degree) is less.

However, in the conventional patent it can be seen that the degree of deformation is severe enough that the degree of shrinkage is 10% or more, as shown in Figs. 1 and 2, in particular, in the case of carnations, the flower collapsed as a result.

In addition, by dividing the degree of shattering into five grades, the fifth grade indicates severe debris, and the first grade indicates less debris. In the case of carnation, the leaf vein is so strong that there is almost no debris. In this case, the degree of crumbs is so severe that it can be seen that the value as a product is lost.

And, in the conventional patent, the result of applying to only one rose variety is presented, and proper dyeing is important for directing as close as possible to the natural flowers, but the dye ratio for proper dyeing is not presented, and the range applicable to the plant is in the entire cut flower. There was a problem of limitation that is limited to the flower part of cut flowers that is not applicable.

In order to solve the above problems, the object is to provide a liquid composition for plant preservation to improve the existing debris and to minimize the shrinkage of the resulting contrast.

Another object of the present invention is to provide a method for treating plants using a liquid composition for plant preservation to improve the existing debris is severe, and to minimize the shrinkage of the result compared to the original.

In the present invention, Huntercolorimeter L, a, b values were measured by using a color difference meter (ChromameterCR-400, Minolta) in order to suggest a proper dye ratio for staining as close as possible to the naturalization.

In the present invention, an air purifying function of decomposing harmful substances in the air is added to the preserved object by reacting a photocatalyst (Tio2 Titanuim Dioxide) solution with the injection light.

In the present invention, the natural fragrance extract or phytoncide solution of the plant is preserved in the microcapsules, and the capsule is bursted by a slight wind or a little artificial force, while the fresh fragrance is continuously released and is semi-permanent. Depending on the fragrance component, such as removing odor and feeling better, it has several additional effects.

In addition, the present invention is not intended to limit the range that can be applied to plants, but to separate the flower part and the stem part and proceed with experiments in different ways to present a process of making a single product by combining the respective results again. The purpose is.

In one embodiment of the present invention to solve the above problems in the liquid composition for preserving the flower part of the plant, 20 wt% polyethylene glycol having an average molecular weight of 200; 10 wt% of polyethylene glycol having an average molecular weight of 400; 50 to 60 wt% of a mixture of acetone and ethyl alcohol; It comprises 10 to 20% by weight of ethyl acetate.

According to another embodiment of the present invention, in the liquid composition for preserving the stem portion of the plant, 30 to 70% by weight of glycerol; It includes 30 to 70% by weight of distilled water.

In the treatment method for preserving the stem portion or houseplant of the plant according to an embodiment of the present invention, liquid immersed in a solution containing polyethylene glycol, acetone, ethyl alcohol and ethyl acetate and dyes for dyeing and plant preservation A one step process of infiltrating the composition; A two step process of washing in the first step solution; It comprises a three-step process for drying.

In the treatment method for preserving the flower part of the plant according to an embodiment of the present invention, a one-step process of dipping and decolorizing by dipping in a solution of acetone and ethyl alcohol to remove the tissue water and pigments and; A two-step process of immersing in a solution containing polyethylene glycol, acetone, ethyl alcohol and ethyl acetate and dye to infiltrate the liquid composition for dyeing and plant preservation; A three step process of washing in the solution of the first step; It includes a four-step process for drying.

According to an embodiment of the present invention, the polyethylene glycol is 30% by weight, acetone and ethyl alcohol mixture is 50 to 60% by weight, ethyl acetate is 10 to 20% by weight; characterized in that consisting of.

According to an embodiment of the present invention, 1.0 g to 1.5 g of a dye is mixed with respect to 300 ml of the liquid composition for plant preservation, in which the polyethylene glycol, acetone, ethyl alcohol and ethyl acetate are mixed.

According to one embodiment of the present invention, the treated plant is subjected to a photocatalyst treatment, and the flavored microcapsules are fixed to the treated plant.

The present invention has the advantage of minimizing the shrinkage of the resultant to the circular shape by preventing the absorption of moisture in the natural flowers, maintaining the natural texture of the plant prototype and long-term storage.

Hereinafter, the configuration of the most preferred embodiment of the present invention.

As a material, flowers of rose and carnation are used, and other kinds of flowers such as hydrangeas and phalaenopsis eggs can be introduced.

The present invention uses a mixture consisting of acetone and ethyl alcohol as a dehydration solvent to replace the tissue water of the leaves in order to preserve the flower part, and undergoes a one-step process of dehydration and decolorization, followed by polyethylene degreasing while replacing the dehydration solvent. In order to infiltrate the colloid, polyethylene glycol, acetone, ethyl alcohol, ethyl acetate, and preservative solution containing dye, etc. are infiltrated.

In particular, in the first step of dehydration and decolorization, the rose and carnation biodegradation is precipitated in 50% ethyl alcohol and 50% acetone solution for about 12 to 24 hours depending on the size of the biodegradation, followed by dehydration and decolorization. This is because in the existing patent 100% ethyl alcohol did not have a significant effect on the rose, but in the case of carnation caused a deepening of the shrinkage.

The second step is the process of penetrating the liquid composition for plant preservation. The proportion of polyethyl glycol substituted with breakfast water in the plant is similar to the existing patent, but it is changed in the part using only low alcohol such as ethyl alcohol. In order to prevent the chipping, ethyl acetate and 10% by weight to 20% by weight of acetone were added to precipitate for 24 to 48 hours depending on the size of the flowers.

As shown in Table 3, the liquid composition for plant preservation of the present invention is mixed with 20% by weight of polyethylene glycol having an average molecular weight of 200, 10% by weight of polyethylene glycol having an average molecular weight of 400, and 50% to 60% by weight of acetone and ethyl alcohol. It is preferably made of a composition ratio of 10 to 20% by weight of ethyl acetate.

Similarly, in Table 4, 100% of the initial state of the natural flowers is measured, and the degree of shrinkage is measured in the state in which the natural flowers are precipitated in the plant composition liquid composition of the present invention. As a result of testing the degree of chipping with a state of almost no deterioration as a grade 1, the degree of shrinkage of roses and carnations in the test results tested by the plant composition solution of Examples 1 to 9 of the present invention. 3 and 4 is significantly reduced compared to the conventional and almost preserved circular, in particular, in the prior art, the degree of shrinkage of the carnation was about 15%, but it can be seen that the 2 ~ 4% is good.

 <Divided into 5 levels> Severe … … … … Almost no crumbs 5... … 4… … 3... … 2… … One

In addition, the degree of crushing was also good, the degree of crushing rose less than 2 grades, the carnations were all 1 grade, the result was in the state of no crushing.

In the three-step washing process, 50% ethyl alcohol and 50% acetone solution may be washed. Soaking in this solution for a long time may cause the leaves to crumble and cause a loss of marketability.

Step 4 is a drying step, which takes more than 48 hours when drying in a place where natural light does not shine at room temperature, but it is sufficient to dry at 40 ° C. for 4 to 12 hours using a dryer to shorten the time.

On the other hand, according to an embodiment of the present invention, the preservation treatment method of the stem portion or houseplant, etc. of the plant, except for the dehydration and decolorization process in the above-described flower partial preservation method, so that only two to four steps to go through It is preferable that the description thereof will be described later.

Color difference meter  Used Color difference  Measure :

Hunter colorimeter L, a, b values were measured using a color difference meter (Chromameter CR-400, Minolta). The L, a, and b values are automatically calculated by the colormeter analysis system, and the L value is lightness (Black = 0, White = 100) and the a value is color (Red-Green: Red = + 100). , Green = -80), and b value is indicated as saturation (Yellow-Blue: Yellow = + 70, Blue = -70) (L is lightness, a is hue, b is saturation).

The final analysis calculated ΔE (color difference value) = [(ΔL) ² + (Δa) ² + (Δb) ²] ¹´² to determine the color difference value of the rose grown and the rose precipitated in the preservation solution of the present invention. By comparison, it is suggested that the dye ratio is close to the flower of rose.

To this end, first, the average value by measuring the L, a, b value of fresh rose is shown in the table below.

L, a, b mean value of flowering roses L a b 24.1 58.81 16.08

In addition, the color difference L, a, b value and ΔE value of the rose treated according to various embodiments by varying the amount of the dye in the plant composition liquid composition of the present invention are shown in Table 6. The dye used basic RED dye.

<Color difference L, a, b value and ΔE value of rose treated with liquid composition for plant preservation of the present invention>

In other words, when comparing the flowers of the rose of the table 5 and the rose treated with the liquid composition for plant preservation according to the present invention of Table 6, color difference in the preservation treatment of roses with a content of 1.0g ~ 1.5g dye 300ml standard solution The value (ΔE) appeared similar to natural flowers, meaning that it is closest to natural flowers.

Photocatalyst  Add Experiment: < chamber  Air Purification Experiments>

A photocatalyst is a substance that catalyzes the reaction when light hits the surface. For example, they are photocatalyst microparticles | fine-particles, such as anatase-type Ti02 (titanium dioxide, a metal band width 3.2eV, wavelength 388nm) of 1-100 nm. Titanium oxide (titanium oxide) includes rutile type Ti02 (metal band width 3.0 eV, wavelength 414 nm), titanium trioxide (Ti03), etc., in addition to anatase type Ti02, but any may be used. These photocatalysts are appropriately called titanium oxide. Moreover, as a photocatalyst, zinc oxide (ZnO, gold band width 3.2eV, wavelength 388nm), strontium titanate (SrTi02, gold band width 3.2eV, wavelength 388nm), tungsten trioxide (W03, gold band width 3.2eV, wavelength 388nm), etc. You can also use When light is emitted, electrons and holes generated by the movement of electrons react with various oxygen, hydrogen, or OH- to decompose pollutants, show sterilizing effect, and remove and absorb harmful gas. do. Photocatalyst has the functions of air pollution purification, antibacterial and sterilization, organic pollutant decomposition and deodorization and deodorization, antifouling function and water environment problem solving. And because of its self-cleaning effect, it is applied to various fields such as glass, tiles, cleaners, refrigerators, curtains, and the like.

In the present invention, by spraying a photocatalyst to the flower treated with a liquid composition for plant preservation, it is possible to prevent the visual damage of the product by adsorption of air pollutants, dust, etc., and may have an air purification effect on volatile organic compounds or formaldehyde. have.

In order to examine the air purification effect of the photocatalyst treated flowers according to the present invention, the air purification experiment was performed using the total 20 L chamber as shown in the figure. A sample in the chamber was taken through the hole at the top to allow concentration measurements. A fan was installed to prevent the concentrations from being unevenly distributed by the stopped airflow in the chamber.

<Air purification measurement chamber>

An empty chamber (control) and a photocatalyst treated carnation or houseplant (boreal fern) according to the present invention were placed in the chamber for 12 hours, and measured by treating formaldehyde with contaminants. HPLC test method was used for accurate analysis of formaldehyde. Ti02 was used as the photocatalyst.

<Current Formaldehyde Concentration Graph of Carnation (Unit: ppb)>

<Current Formaldehyde Concentration Graph of Houseplant (Gob Gobi) (Measurement Unit: ppb)>

In the two graphs, the control (empty chamber) formaldehyde stabilizes after 3 hours, maintains a constant value, and no longer falls from 800 units, but the chamber containing the photocatalyst-treated carnation and goblin fern forms formaldehyde. Shows the actual removal.

         <4 hour formaldehyde removal rate>

When the amount of formaldehyde was removed for 4 hours, the carnations removed 74, 77 and 72%, respectively, and the goblins removed 82, 80 and 77%, respectively. After 4 hours, the pattern was similar.

The reason that formaldehyde is not reduced in 200 units after 4 hours is that there is formaldehyde which is generated by itself (fan, temperature and humidity, chamber, etc.) even when the chamber is initially washed with air (pure air). This is because formaldehyde of 220-260 is always present at the beginning.

Incense Micro Capsule Injection:

Perfume microcapsule is the encapsulation of an optional polymer membrane wrapped around the outer wall using microcapsule technology in the fragrance of fat-soluble ingredients (liquid). By solidifying the fragrance of the liquid in this way it can be used in various forms according to the user's use and purpose. In particular, by using the flavor microcapsules fixed to the flower according to the present invention can also obtain the effect of aromatherapy by natural flavor. The fragrance microcapsules are slowly released and can be used semi-permanently.The microcapsules are destroyed with time difference by adding natural vegetable flavors containing phytoncide ingredients so that the effect of sterilization or dissipation of fragrance substances can be continuously achieved during the use period. can do. Natural vegetable essential oils can be extracted and used in almost all plants, such as herbs and flowers. Photocatalysts can also be used as microencapsulations with these natural fragrances. In addition, the capsule surface is nano-silver (silver) to maintain strong sterilization and antibacterial, can remove various bacteria and viruses in the air.

   <Microcapsules>

The fragrance sensory evaluation was carried out for three weeks in the group treated with the flavor microcapsules, the group treated with the general perfume, and the group treated with nothing.

According to the present invention, the experimental group did not have any incense to the flowers did not have any incense, and the group treated with general fragrance did not have any incense from the day four days after the fragrance gradually weakened from the next day while maintaining the incense on the first day. On the other hand, when the microcapsules were treated with fragrance, the fragrance lasted for 3 weeks.

Existing products maintain the appearance of the plant in the form of an appearance, but it does not have any fragrance is not enough to feel alive live, but the present invention has a fragrance like real flowers, there is an effect that can give a more lively.

Experiment on plant stem part:

In the process of replacing the stem part from which the flower part of the plant is removed with the liquid composition for plant preservation, glycerol is used in place of polyethyl glycol in the plant preservation liquid composition used to replace the flower part of the plant and distilled water in place of the alcohols It was carried out using.

When the same method as the existing flower part is severely deformed, such as crushed leaves, but when carried out with the composition of glycerol distilled water, the original shape of the leaf is maintained and the deformation did not occur. Also, unlike the existing process, the dye and plant preservation liquid composition penetrating process, which omitted the first process of dehydration and decolorization, was immediately performed. The following procedure was carried out as shown in Table 6.

As shown in the photograph of Table 8, the leaves were kept fresh, and in particular, the best reaction was observed in 50 times of glycerol 3 times and 50% of distilled water, and the prototype was almost preserved as shown in FIG. The above method is applicable not only to the stem of the rose, but also to various houseplants used for indoor landscaping, such as Namcheon, bamboo, goblin fern, and moss.

In addition, it is possible to produce a differentiation product planted in a pot by treating the entire plant with a liquid composition for plant preservation, including the root as shown in FIG. Plants treated with preservatives in spaces where environmental conditions are not suitable for sustaining the growth of the plants, for example, where the temperature is too high, on the contrary, the temperature is low, or where there is not enough light, can not be planted. It is possible that the range of use is vast.

These products can be treated with photocatalyst treatment or fragrance microcapsule treatment just like flowers, and the effect is expected to be greater when large-scale planting is used for indoor landscaping.

Combination of Flowers and Stems

As a result of each of the above-described results, as shown in Figs. 7 and 8, a single rose can be produced by combining flowers and stems as one bar, and Fig. 7 shows a state in which the entire rose stem is preserved as a composition of the present invention. 8 illustrates an example in which a rose flower part and a stem part are combined. As can be seen from these drawings, the existing short stems have limitations in the production application, and have been supplemented to the fact that they are not realistically different from natural flowers because they are dyed in the same color as flowers until calyx, and FIG. 9 is commercially available in Japan. The product is an example. In the case of Japanese products, plants such as roses tend to be deformed or bent due to their weak necks. To prevent this, the stems are cut and attached to remove the weak parts.

Therefore, in the present invention, a fixture such as a wire is put in the neck portion and the neck portion is fixed so as not to be deformed. It can be connected without breaking the stem, so it can increase the appearance of commerciality and give a more natural feel than existing products.

Therefore, the present invention can be produced in a variety of products can be produced by the production of a single rose.
