Description
Technical Field
The invention belongs to the technical field of permanent flower manufacturing, and particularly relates to primary-color permanent flowers and a manufacturing method and application thereof.
Background
The perpetual flowers are also called preserved flowers and ecological flowers. The permanent flower is a flower product made of rose, carnation, butterfly orchid and other products, and is a dried flower made up by using fresh flower and making it undergo the processes of dewatering, decolouring, drying and dyeing. The perpetual flower keeps the special quality of fresh flowers, has richer colors, has the preservation time of at least 3 years, and is a flower deep processing product which is most ideal for floriculture design, home decoration and celebration activities.
Although the characteristics of the fresh flowers can be kept to the maximum extent in terms of color and quality, the color of the finally obtained permanent flowers has the problem of large color distortion degree compared with the original flower color after the original flower color is subjected to the processes of decolorization and dyeing in the processes of dehydration, decolorization, drying and dyeing.
In order to solve the technical problems, chinese patent CN201810191699.2 adopts an epoxy resin plasticizer to plasticize the fresh flowers after color protection and drying treatment, and then performs vacuum drying, which can solve the problem of color distortion of the fresh flowers to a certain extent. However, epoxy resin plasticizers and the like have certain toxicity, and although the content of the epoxy resin plasticizers and the like in the prepared immortal flower is low, the contact amount of workers for producing the immortal flower is large, and the health of the workers is not facilitated. Therefore, it is necessary to develop a method for producing a permanent flower which has high safety and can protect the original color of the flower.
Disclosure of Invention
In order to solve the technical problems, the invention provides a primary-color permanent flower and a manufacturing method and application thereof.
The invention aims to provide a method for making primary-color immortalized flowers, which comprises the steps of cleaning the flowers, draining off water, alternately treating the flowers by adopting a 40-45 ℃ drying and color protection liquid wetting mode, spraying the color protection liquid containing a color protection compound to wet the flowers after each drying, standing for 10-30min, and alternately treating at least twice; the color protection compound is one of sodium citrate, sodium pyrophosphate or sodium hexametaphosphate; and finally, drying the flowers to obtain the original-color permanent flowers.
Preferably, the method for preparing the primary-color immortalized flowers comprises drying for 15-30min at 40-45 ℃ each time.
Preferably, in the method for manufacturing the primary-color immortalized flower, the formula of the color protection liquid in percentage by mass is as follows: PEG 4002-5%, glycerin 1-3%, antioxidant 1-3%, color protecting compound 1-2%, and PBS solution with 0.01mol/L pH 7.0 for the rest.
Preferably, in the method for producing the primary-color immortal flower, the antioxidant is L-ascorbic acid or sodium L-ascorbate.
Preferably, in the method for manufacturing the primary-color immortalized flower, the temperature of the color protection liquid is 40-45 ℃.
The invention also provides the primary-color permanent flower manufactured by the method.
The invention also provides application of the color protection liquid in preparation of peony and rose permanent flower.
Compared with the prior art, the invention has the following beneficial effects:
1. according to the method, a drying means of 40-45 ℃ is adopted, so that on one hand, the water in the flowers is promoted to volatilize, on the other hand, the structural stability of the flower color pigment is subjected to high-temperature domestication treatment, and the risk that the permanent flowers fade quickly under the subsequent high-temperature storage environment is reduced; the original color of the flowers is protected by adopting a mode of alternately treating the flowers by drying at 40-45 ℃ and the color protection liquid, and no plasticizer harmful to human bodies is adopted in the preparation process, so that the flower color protection agent is environment-friendly and safe.
2. The drying time is 15-30min at 40-45 ℃ each time, the moisture of the flowers is not completely lost, so that when the color protection liquid is sprayed, the humidity change of the semi-dried flowers is smaller than that of the completely dried flowers, the structural damage of substances such as flower cells, plant fibers and the like caused by overlarge humidity and moisture change is reduced, and the beautiful structure of the flowers is kept to the maximum extent.
3. PEG400 in the color protection liquid has the effects of solubilizing and protecting color, the oily effect of glycerin can reduce the color fading of the pigment caused by wind blowing, the antioxidant has the effects of protecting color and resisting oxidation, and the PBS solution with 0.01mol/L and pH of 7.0 has the effects of a solvent and buffering pH, so that the color fading phenomenon caused by slight change of environmental pH can be prevented. The color of the permanent flower manufactured by the embodiment of the invention can not be seen by naked eyes within 2 years.

In the above examples and related control experiments, to track the color change during the production of immortal flowers, we randomly selected the middle position of a flower petal, measured the lightness L, the red-green degree a, and the yellow-blue degree b using the color difference instrument CIE color system, and marked the position, and the values L, a, and b of the flower petal were used as standard values for comparison with the test samples. After the immortal flower was produced, the lightness L, red green a, and yellow blue b values were measured at the marked positions, and the values Δ L ═ flower L ═ value-immortal flower L ═ value, Δ a ═ flower a ═ value-immortal flower a ═ value, Δ b ═ flower b ═ value-immortal flower b ═ value were calculated. Final calculation
In each method, 3 petals are randomly selected for testing, and the average value delta E of the 3 delta E is takena，ΔEaThe smaller the color distortion of the manufactured immortal flower is, the smaller the color distortion of the manufactured immortal flower is. The results are shown in Table 1.
