How to treat flowers for preservation { Pre-treatment of flowers for preservation }

In order to preserve the leaves, stems, flowers, fruits, etc. of cut flowers softly and vividly like real flowers for a long time, the total synthetic amount of eco-friendly oils, solvents, surfactants, distilled water, fungicides of inorganic materials, natural dyes, etc. It relates to the optimal manufacturing method synthesized through various experiments and analyzes according to.

'Preserved' in 'preserved flower' means 'preserve' and means a flower that is preserved for a long time like a fresh flower. Fresh flowers) are processed with a softener solution and made to retain their original shape, keeping the freshness, flexibility, and unique shape and characteristics of fresh flowers intact. Unlike dried flowers, the original form of flowers is maintained, and It has the advantage of being able to create colors that do not exist, so it is attracting attention as a material for the flower industry. In 1987, Preserved Flowers, colored with rudimentary techniques, were created in Belgium. After joint research at the University of Brussels in Belgium and the University of Berlin in Germany, Vermont of France obtained world patent recognition for the first time in 1991 and began to spread throughout Europe, resulting in popular consumption in the United States and Japan. It has spread to many countries around the world. Flower decorations based on nature are mostly made with cut flowers and fresh flowers, so there is a limit to the time to appreciate the beauty for a long time.

In order to compensate for these disadvantages, the use of dried products using cut flowers, cut leaves, stems, fruits, roots, etc. has recently increased. Dried flowers are vegetable materials that have a longer viewing period than live flowers and maintain their natural beauty, but are easily discolored or discolored, so they cannot maintain the same texture as live flowers for a long time, and are easily broken during drying, making storage and transportation difficult.

In order to compensate for the disadvantages of drying, various types of dried materials are produced in foreign countries by using a method of treating leaves and flowers with glycerin and then drying them. Preserved flowers and preserved leaves that can show various colors by absorbing preservative dyes and dyes after dehydrating and bleaching the flower tissue of cut flowers have been developed.

A lot of research on preserved flowers and preserved leaves that can show various colors while maintaining the shape of cut flowers has been conducted in advanced countries such as Japan and Europe, and is being distributed as a product in the existing market as a material for flower decoration. In recent years, in accordance with the need for various flower decorations in Korea, research on the drying processing and quality of preserved flowers and preserved leaves that can maintain the same texture and express natural beauty by going one step further from dried flowers or pressed flowers processed from existing flowers in Korea. Papers, etc., have been published. However, it is not yet systematized by diversity and various plants for the production method of preservation flowers.

In Korea, many research and development cases on preserved flowers and preserved leaves have been reported in academic circles and production sites, such as papers and patents, and are already widely distributed as products in the existing market as a material for flower decoration. Due to the long-term situation of Corona 19, it is experiencing a period of stagnation due to the unfortunate global situation, but in accordance with the need for various flower decorations in Korea, it is a step away from dried or pressed flowers that have processed existing fresh flowers, maintaining the same texture as fresh flowers and showing natural beauty. Conservation and research on preserved leaves are being carried out steadily.

R&D is not consistent from the preparation stage of flower arrangement to the exhibition deadline, and most of the solutions and products are composed of additives or combinations of chemicals such as solvents, surfactants, fungicides, etc. at each stage. In the present invention, it is felt that there is an urgent need for methods such as preservation solutions and preservation products made through the process of verification of nutritional status, etc. through the process of research and development and analysis experiments based on an eco-friendly and systematic scientific approach. and analysis and development.

Since the quality of preservation varies depending on the type of flower, dehydration, coloring, and treatment concentration and time of preservation dyes, it is necessary to continuously conduct experiments to investigate conditions according to plant species and varieties. In addition, even when examining various types of patents, there was a problem in that it was difficult to apply them consistently according to the growth conditions of many plants, seasonal factors, soil and weather conditions.

Accordingly, the present applicant applied for the present invention by conducting many studies and analysis experiments focusing on large petal plants that are difficult to apply by the water raising method.

As shown in FIG. 1, the method for treating flowers for preservation and preparing a preservation solution according to an embodiment of the present invention includes a sample preparation step (S10), a sulfur silicic acid pretreatment step (S20), a dehydration step (S30), and decolorization. It is composed of a step (S40) and a coloring preservation step (S50).

1. Sample preparation (S10) step

First, a sample is prepared by cutting off the tip of the plant prepared in the sample preparation step (S10). As a preparatory work for making preserved flowers, check the condition of the plants you need, such as roses, chrysanthemums, tulips, carnations, hydrangea, Denpara, Pablo, cheonilhong, calla, peony, lily, and barley, and learn how to harvest and purchase them. Prepare the material by Maximize the volume of the cut surface of the prepared material, cut the ends, and arrange the size according to the required use. Maximize the volume of the cut surface of the prepared material, cut the ends, and arrange the size according to the required use.

2. Sulfuric acid pretreatment (S20) step

Next, in the sulfur silicic acid pretreatment step (S20), a water-soluble ionic solution (sulfur silicic acid aqueous solution, ion water-soluble promoting nutrient solution) containing silicic acid and sulfur is applied to the sample or topped with water and naturally dried.

Sulfur silicic acid water-soluble ion solution (ion water-soluble promoting nutrient solution, or sulfur silicic acid aqueous solution), which is a solution of silicic acid component (or silicate ion, nutrient component) and sulfur component (or sulfate ion, sterilization component), is applied to the sample or raised with water. and dry naturally.

The sulfur silicate aqueous ion solution contains silicate ion (nutritional component) [SiO ₃ ] ^- and sulfate ion (sterilization component) [SO ₄ ] ^2- . Sulfur, a sulfur substance, is dissolved in water at about 130 degrees Celsius by stirring for several hours to dissolve it, thereby generating sulfate ions.

Clogging of conduits and decay of cutting parts by bacteria in preservation manufacturing have been mainly reported in academia and work sites as the main causes of failure so far. In order to protect the double layer of the plant fibrous cell wall thickly and preserve the bactericidal power for a long time, silicic acid and sulfur ingredients are purchased and prepared as an eco-friendly ion-soluble promoting nutrient, and the sample is prepared by side fertilization, watering, and natural drying.

In one embodiment of the present invention, the sulfur silicic acid aqueous ionic solution is prepared by mixing 84 to 92% by weight of fresh water, 3 to 7% by weight of purified silicic acid grains, and 5 to 9% by weight of purified sulfur grains. More preferably, the aqueous sulfur silicic acid ionic solution is prepared by mixing 88% by weight of fresh water, 5% by weight of silicic acid grains, and 7% by weight of sulfur grains.

Silicic acid grains are pure purified in a furnace so that they are easily water-soluble. Sulfur uses high-purity sulfur grains that have been refined so that they can be easily dissolved in water at an appropriate temperature. If there is too much sulfur, the sterilization component is excessive, and if it is too little, mold and bacteria are generated due to insufficient sterilization component, so it was found that 5 to 9% by weight of sulfur grains is suitable for sterilization. When the weight ratio of sulfur is 5 to 9% by weight and the weight ratio of silicate grains is 3 to 7% by weight, the overall bactericidal action and the protective effect of the cell wall are balanced, and the test results show that the preservation function of sterilization and preservation is excellent. If the amount of silicic acid is excessive, there is a problem that gel-type coagulation occurs during the dissolution process, and if it is too small, there is a problem that the cell wall protection effect is lowered.

Nutrients of various elements necessary for plants are best absorbed when they are water-soluble and ionic. Ionic silicic acid necessary to thickly protect the double layer of plant fibrous cell walls, and ionic sulfur with excellent performance to preserve sterilizing power for a long time. Purchased two raw material grains and mixed 88% of fresh water with 5% silicate grains and 7% sulfur grains. When it is made into an aqueous solution, it becomes a water-soluble ionic solution containing sulfur and silicic acid. The raw water solution thus prepared is subdivided into a certain container. The manufacturer dilutes the solution 500 to 1000 times according to the size of flowers and leaves.

3. Dehydration step (S30)

In the dehydration step (S30), the sample is dehydrated by immersing in an ethyl alcohol (C ₂ H ₅ OH) solution for 3 to 4 days. In order to find out the appropriate dehydration time of the material, it is immersed in ethyl alcohol (C ₂ H ₅ OH): 99% solution for 3 to 4 days. In order to confirm the effect of ethyl alcohol treatment time on dehydration, daily weight change was measured for 5 days after ethanol treatment, and it was determined by checking the condition of the plant.

4. Decolorization step (S40)

In the bleaching step (S40), the sample is immersed in a mixture of ethyl alcohol (C ₂ H ₅ OH) solution and hydrogen peroxide solution to decolorize. For decolorization of each sample, a mixture of hydrogen peroxide solution and ethyl alcohol solution was used in a weight ratio, and each sample was analyzed by methods such as electron microscopy and weight measurement through an experiment of immersion for 1 to 5 days. As a result, it was found that there was a difference in the decolorization time depending on the type of flower, variety, and leaf type, and it was confirmed that 2 to 3 days was appropriate in terms of time and rationality.

5. Coloring and preserving treatment steps

In the coloring preservation step (S50), the sample after dehydration and decolorization is precipitated in a solution in which 0.2 to 2% by weight of dye of the required color is mixed with 100% by weight of the preservation solution, and left for 2 to 4 days. For coloring, a vegetable dye of the color used among various dyes on the market was prepared, mixed well in an ethyl alcohol solution in a weight ratio according to the color characteristics of the dye, and then foreign substances were removed to prepare a preservation dye solution.

Mix the dye of the required color with the preservation solution, precipitate the sample after dehydration and decolorization, and leave it for 2 to 4 days. It is okay to maintain the temperature of the processing room up to 40℃, but considering the overall situation of economic feasibility and constant temperature and humidity, it was safe to keep the temperature above 25℃ (appropriate between 25℃ and 40℃), and the container should be sealed in principle. The volatility of the solution and the safety of the workplace were maintained, and after immersion, it was dried for 4 to 7 days in a drying facility equipped with exhaust facilities.

6. Long-term storage method

For long-term plant preservation, mix ethyl alcohol solution, polyethylene glycol, and isopropyl alcohol well and use it as a 100% preservation solution. The weight ratio of ethyl alcohol and isopropyl alcohol is good at reducing foaming, and by testing the effects of volatility and dye solubility, etc., it was confirmed that there is an effect on the size and maintenance performance of the conduit. and intracellular vacuoles are impregnated to maintain moisture and moistness, weight and beauty like fresh flowers for a long time.

It can be stored for a long time, but if exposed to direct sunlight for a long time, deformation may occur.

It is a raw material for manufacturing sulfuric acid·carbon disulfide··match··black gunpowder··dyes, and is widely used for vulcanization of rubber (sulfurization·deoxidized sulfur·sulfur powder·precipitated sulfur·colloidal sulfur, etc. are used). In addition, it is used as a raw material for manufacturing agricultural chemicals and insecticides, and is used in the pulp industry (sulfurous acid method) and synthetic fiber industry. As for medicines, local irritants, parasiticides, saccharides, and purified sulfur for internal use are suitable, and as a laxative for constipation and Used for dental patients. It is possible to check whether iron ions, copper ions, lead ions or cadmium ions are contained in the solution by the sediment formation reaction using sulfide ions (S ^2- ).

Silicate [ silicate, 硅酸鹽 ]

SUMMARY Generic term for neutral salts in which hydrogen is substituted with metal atoms of various silicic acids, compounds containing anions in which one or more silicon-centered atoms are surrounded by negatively charged ligands. It is the general formula xMI2O·ySiO2 (M is a monovalent metal). It is produced in large quantities in the natural world, occupies most of the earth's crust as the main component of rock formation minerals, and is also present in other celestial bodies. Aluminum salts, iron salts, calcium salts, magnesium salts, and alkali salts are the most common. They usually have a low melting point and are easy to form glass when the melt is cooled. It is insoluble in acids and alkalis, but is decomposed by hydrofluoric acid.

Silicate tetrahedron : Structurally, the regular tetrahedron of [SiO ₄ ] ^4- is a unit, and it is regularly arranged and cations enter the gap to form crystals. Four oxygen atoms are strongly bonded to the silicon cation. Most of the strong bonds they form are covalent bonds. Within the silicate anion, the oxygens are arranged in the form of four spheres to occupy the narrowest space. The four oxygens are arranged at the vertices of the tetrahedron, and the silicon cation, which is relatively small in size, is located in the center of the tetrahedron formed by the oxygen, so the silicate is formed in the form of a tetrahedron. Silicates are characterized as safe because of macroions. Materials commonly used in everyday life contain a lot of silicate, and glass, refractories, cement, ceramics, etc., which are the main subjects of ceramics, all use the special properties of silicate.
