Description
Technical Field
The invention relates to the technical field of color preservation and shape protection of flowers, in particular to a planar dry pink color reduction method for gladiolus hybridus var.
Background
Dried flowers are becoming more and more popular due to their natural, plain, durable characteristics and unique artistic appeal. The dried flower is deeply loved by people because of the irreplaceable advantages of fresh flowers and artificial flowers, and the decorative art of the dried flower also becomes a unique expression form. In the future, dry flower artware such as festival slices, birthday slices, wedding slices, beautiful bouquets, gift mirrors and the like sold in the market are popular with people and have a good development prospect. The dried flower has the advantages of wide material source, natural and simple posture, convenient use and management, random originality and convenient application. The plant material often has color change phenomenon in the drying process, the plant material also has color change phenomenon after being placed for a long time, and pink is the most color easy to fade after the fresh flowers are dried. In order to change the defect, the petal color reduction treatment is adopted to achieve the ideal ornamental effect.
The planar drying method includes natural drying, baking, microwave drying, etc. The color treatment of the embossed flower material may be divided into a color-retaining treatment before embossing and a reducing treatment after the embossing is left for a certain period of time. The color-keeping treatment method comprises soaking treatment of chemical reagents, smearing treatment, internal absorption treatment or a combination of the above methods. For color retention treatment of the flower material of the red color powder color system, HCl, citric acid, tartaric acid, stannic chloride, magnesium chloride and the like are commonly used as reagents. The reduction treatment of the planar dried flower also commonly uses a method such as soaking and smearing, and commonly uses citric acid, tartaric acid and the like as a reduction reagent.
Tang Chang Pu (rhizoma Acori Graminei)Gladiolus gandavensisVan Houtte) is one of four fresh cut flowers in the world, small flowers are arranged into more than 20 scorpion tails, the flower color is various, the flowering phase is long, the color is various, and the dried flower is a good source of dried flower materials. However, due to the specific chemical components and properties of gladiolus and the structure of flowers, the conventional soaking or applying method is difficult to obtain a good effect.
Disclosure of Invention
The invention solves the technical problem of color protection and shape protection of the traditional gladiolus planar dried flower and provides a gladiolus planar dried flower pink color reduction method.
The invention is realized by the following technical scheme:
a method for reducing the planar dry pink color of gladiolus hybridus comprises the following steps:
s1, coating the positive and negative surfaces of the petals with prepared color retention agents respectively, repeatedly coating for 2-4 times, and then drying;
s2, drying the gladiolus petals aired in the S1 by microwave for 40-50S, wherein the microwave power is 620-660W;
the color retention agent is 25% tartaric acid or 20% -25% citric acid.
Preferably, the gladiolus petal drying method comprises the following steps: the method comprises the steps of stacking petals on a microwave embossing plate, then placing the microwave embossing plate into a microwave oven to be heated for 60s, wherein the microwave power is 620-660W, wiping off moisture on the embossing plate after the petals are taken out, then placing the petals into the microwave oven to be heated for 30s, taking out the petals, transferring the petals onto old newspaper, covering a layer of newspaper on the petals, and then clamping the newspaper in a specimen folder or a thick book for 24 h.
Preferably, the microwave frequency is 2450 MHz.
The method adopts a microwave drying method, and uses a microwave embossing device and a microwave oven to quickly dry the flowers and materials, thereby improving the color retention effect. The microwave embossing device and the microwave oven are used for drying the materials to be dried, the required time is short, the temperature efficiency is high, the drying effect can be influenced by small time deviation, and the required pressing time of each material is different due to the difference that the materials have different textures, different water contents and the like. The invention unexpectedly discovers that the color reduction effect on gladiolus petals is best under the process condition.
The dried flower is often lost in color after being dried by external influence during storage and use. The way that the original color of the dried flower is restored is changed into the color restoration of the dried flower through some physical and chemical methods. The research of the invention finds that the bound water is lost in the storage process, the original colloid state of the dried flower is changed in pH value, and the pigment can be transferred to red by treating with the acidic chemical reagent, so that the petals are converted to the original color as much as possible. The method carries out reagent smearing treatment on the dried petals, so that the petals are reduced in color, the reducing power is strong, and the petal color reducing effect is obvious.
In the process of pressing, drying and storing the plant material, whether the original color of the flower material can be stored is the key of the embossing technology. The red color in the petals is mainly presented with anthocyanin as a main body, and the anthocyanin changes color along with the difference of acid and alkali. The color retention of the flower color is mainly realized by adjusting the pH value in the plant material, complexing with metal ions and promoting the generation of colloid state in cells by using a medicament, thereby improving the stability of the pigment.
The flower color causes are very complicated, and for example, the flower color changes are influenced by the content of pigments in cells, the relative content of various pigments, the physicochemical properties of the pigments, the pH value in cells, co-pigments, metal elements and the like. The pink petals are influenced and differentiated by factors such as the growth characteristics of the plants, the petal components, the outside (illumination, humidity, temperature) and the like.
Compared with the prior art, the invention has the beneficial effects that:
the problem of fading in the drying process of pink gladiolus and the storage process after drying in the manufacturing process of the plane dry flower is solved, the primary color and the shape of gladiolus petals are well kept, the storage life of the embossed artwork is prolonged, and the excellent appreciation effect is achieved; the petals are treated by the color retention agent in a smearing mode, and the microwave drying method is convenient and quick.

TABLE 1 Effect of different treatments with different reducing agents on petal color reduction
As seen from Table 1, the process of the present invention has the best pink reduction effect on gladiolus petals. In comparative example 1, the petals are not taken out to wipe off the moisture on the embossing plate, and in comparative example 2, the petals after being dried by microwaves are not dried for 24 hours by newspaper, so that the reduction effect is much lower than that of examples 1 to 3, which shows that the drying process protected by the invention has unexpected influence on the reduction effect of the gladiolus petals. As is clear from the concentrations of the color-retaining agents used in comparative examples 3 to 6, the color-reducing effect was also unexpectedly affected. As can be seen from the comparative example 7, the method of the invention can not obtain the same effect as gladiolus on peony, and can see that the color and shape protection process of different flower materials is very different. It is clear from the microwave powers used in comparative examples 8 to 9 that the effects of color reduction are also unexpectedly affected.
Because the gladiolus petals are thin, particularly, the gladiolus petals can be thinner after being dried, and if a soaking method is adopted during reduction treatment, the gladiolus petals can be adhered to each other after being soaked, and are difficult to separate and use. The time of soaking treatment is basically proportional to the reduction effect, and the longer the treatment time is, the better the reduction effect is. But the petals soaked for more than 3 hours are completely adhered, cannot be unfolded and cannot be used. And other soaked petals also need to be cleaned by clear water and can be pressed again after being unfolded, so that the operation is not easy.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
