Description

Technical Field

[0001] The present invention belongs to the technical field of processing technology of everlasting flowers, and in particular to a replacement liquid for everlasting rose flowers with better simulation effect, a preparation method and an application thereof. Background Art

[0002] An everlasting flower is obtained by treating a fresh cut flower with a solution to replace the water in its petals with a non-toxic, harmless and non-volatile organic solvent, so as to achieve the purpose of preserving the shape, texture and color of the flower for a long time, eliminating the need for fresh flower maintenance, avoiding pollen allergy, and being able to be preserved for 3 to 5 years, having considerable commercial value and broad application prospects.

[0003] At present, most of the existing formulae of replacement liquids for treating everlasting rose flowers are: 50% anhydrous ethanol, 10% glycerol, 40% PEG-200 (such as the content disclosed in [1] Chen Yanlin. Production and Preservation of Everlasting Flowers [J]. Modern Horticulture, 2020, 43(17): 184+186. and [2] Sun Yangyang. Research on Processing Technology of Everlasting Rose Flowers [D]. Shandong Agricultural University, 2016.). However, through testing, the replacement liquid with the above formula in the prior art is likely to make the edges of the petals of rose flowers show a transparent band of a certain width, resulting in poor dyeing and simulation effects of everlasting rose flowers, increasing the subsequent processing steps and costs, and bringing great inconvenience to production. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a replacement liquid for everlasting rose flowers with better simulation effect, a preparation method and an application thereof.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] A replacement liquid for everlasting rose flowers with better simulation effect, the replacement liquid is composed of the following components in volume percentages:

[0007] 50% anhydrous ethanol, 5% glycerol, 40% polyethylene glycol 200 and 5% benzyl alcohol.

[0008] The preparation method of the above-mentioned replacement liquid for everlasting rose flowers includes the following steps:

[0009] After mixing the components in each volume percentage, an everlasting rose flower replacement liquid is obtained.

[0010] The application of the above-mentioned replacement liquid for everlasting rose flowers in the preparation of everlasting rose flowers.

[0011] The advantages and positive effects obtained by the present invention are:

[0012] 1. The artificial rose flowers treated with the replacement liquid of the present invention have a better simulation effect than those treated with the formula in the prior art. On the basis of maintaining the cost of the original replacement liquid, the present invention can better maintain the bending angle and soft texture of the rose petals in the fresh flower state, and the decolorization is complete. After decolorization, the effect is stable and not easy to change color. The color and texture states of each part of the petals are uniform, and it can significantly improve and solve the defect that the edge of the petals appears transparent and distorted with the original formula, so as to achieve a better simulation effect of artificial rose flowers.

[0013] 2. The present invention mainly solves the problem that the existing replacement liquid for artificial rose flowers easily makes the edges of rose petals show a transparent band with a certain width, resulting in poor dyeing and simulation effects. On the basis of the replacement liquid formula in the prior art (anhydrous ethanol 50%, glycerol 10%, PEG - 200 40%), the content of glycerol in the replacement liquid formula of the present invention is adjusted from 10% to 5%, and a new reagent, benzyl alcohol, with a content of 5% is added to the original formula. Benzyl alcohol is one of the simplest aromatic alcohols, a colorless liquid, mostly existing in essential oils in the form of esters in nature, with a weak aromatic smell, and is commonly used in making spices and flavoring agents, especially in soaps and daily cosmetic fragrances.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The following further illustrates the present invention in conjunction with embodiments. The following embodiments are narrative and not restrictive, and the protection scope of the present invention cannot be limited by the following embodiments.

[0016] All kinds of experimental operations involved in the specific embodiments are conventional techniques in the art. For the parts not specifically noted in this article, those of ordinary skill in the art can refer to various commonly used reference books, scientific and technological literatures, or relevant specifications, manuals, etc. before the filing date of the present invention application for implementation.

[0017] A replacement liquid for artificial rose flowers with a better simulation effect, the replacement liquid is composed of the following components in volume percentages:

[0018] Anhydrous ethanol 50%, glycerol 5%, polyethylene glycol 200 40%, and benzyl alcohol 5%.

[0019] The preparation method of the replacement solution for everlasting Chinese rose flowers as described above includes the following steps:

[0020] After mixing the components with respective volume percentages, a replacement solution for everlasting Chinese rose flowers is obtained.

[0021] The application of the replacement solution for everlasting Chinese rose flowers as described above in the preparation of everlasting Chinese rose flowers.

[0022] To more clearly illustrate the advantages of the replacement solution formula of the present invention in the simulation effect of everlasting Chinese rose flowers, the edge transparency effects of rose petals (A) treated with a replacement solution containing 10% glycerol (i.e., the replacement solution formula in the prior art), rose petals (B) treated with a replacement solution containing 10% benzyl alcohol (i.e., replacing all 5% glycerol in the replacement solution formula of the present invention with benzyl alcohol), and rose petals (C) treated with a replacement solution containing 5% benzyl alcohol and 5% glycerol (i.e., the replacement solution formula of the present invention) are compared in the following by means of attached drawings and tables.

[0023] The specific test method is as follows:

[0024] At room temperature, the petals of freshly cut Chinese rose flowers are soaked in a dehydration solvent (i.e., 100% absolute ethanol) for 24 h, and then quickly immersed in the replacement solution for 48 h, during which the exposure time of the petals to air is less than 2 s. To test the treatment effects of replacement solutions with different formulas, 3 different replacement solution formulas are formulated, and 5 petals are treated with each replacement solution as biological replicates.

[0025] A: 50% absolute ethanol, 10% glycerol, 40% PEG-200 (i.e., the replacement solution formula in the prior art)

[0026] B: 50% absolute ethanol, 10% benzyl alcohol, 40% PEG-200 (i.e., replacing all 5% glycerol in the replacement solution formula of the present invention with benzyl alcohol)

[0027] C: 50% absolute ethanol, 5% benzyl alcohol, 5% glycerol, 40% PEG-200 (i.e., the replacement solution formula of the present invention).

[0028] Take out the petals treated with the replacement solution and naturally dry them for about 5 d, and observe and compare the treatment effects of replacement solutions with different formulas on the petals of everlasting Chinese rose flowers.

[0029] The relevant detection results are shown in Table 1 and Figure 1 , from Table 1 and Figure 1As can be seen, the replacement solutions with different ratios of three kinds of glycerol and benzyl alcohol were used to treat the rose petals. First, it was found that after the rose petals were treated with the replacement solution formula with 10% glycerol (i.e., the replacement solution formula in the prior art), the decolorization effect of the petals was unstable, the color was easy to change, there was a transparent zone at the petal edges, and the petal color was uneven. Second, after the rose petals were treated with the replacement solution formula with 10% benzyl alcohol (i.e., all 5% glycerol in the replacement solution formula of the present invention was replaced with benzyl alcohol), the decolorization effect of the petals was poor, there was obvious residual color, and the petals were severely curled, the edges were brittle, and the simulation effect of the treated petals was poor. Finally, after the rose petals were treated with the replacement solution formula with 5% benzyl alcohol and 5% glycerol (i.e., the replacement solution formula of the present invention), the decolorization was complete, the effect was good, and it could be maintained stably. There was no transparent phenomenon at the petal edges, the petal color was uniform, the petal flexibility was better, it did not wrinkle or curl, and the simulation effect was the best.

[0030] The above test results show that when treating the everlasting rose with the replacement solution, the treatment effects of the replacement solutions containing only glycerol or benzyl alcohol alone are not ideal. However, the simulation effect of the everlasting rose obtained by treating with the replacement solution with 5% benzyl alcohol and 5% glycerol respectively has obvious advantages over the other two, and has a better application prospect. At the same time, it can also be seen that there is a synergistic effect between glycerol with an addition amount of 5% and benzyl alcohol with an addition amount of 5% in the present invention, which can synergistically improve the relevant properties of the prepared everlasting rose and synergistically improve the simulation effect of the prepared everlasting rose.
