Problems solved by technology

The Chinese invention patent whose application publication number is CN105145976A discloses a processing method of immortal camellia, which comprises the following steps: take fresh camellia and soak them in ethanol, then bleach them with hydrogen oxide, wash them with ethanol, soak them in a replacement solution, and dry them to obtain the product; The replacement solution is composed of ethanol, polyethylene glycol, 1,2-propanediol, glycerol, citric acid, sodium citrate, dimethylsiloxane and food coloring; Good color, shape and soft hand feeling, but because the soaking method is used for liquid phase replacement and dyeing, the penetration process of macromolecules such as polyethylene glycol is slow and time-consuming, and it is easy to cause uneven dyeing

Embodiment 1

[0039] The method for preparing immortal flowers by ultrasound-induced osmosis of the present embodiment comprises the following steps:

[0040] 1) Cut off the flower head of the peony flower, leave the flower diameter 3cm, put it in a decolorizing agent and soak it under airtight conditions for 4 hours until the peony flower fades completely; the decolorizing agent used is composed of water and the following components in parts by weight: ethanol 95 parts, 0.9 parts of hydrogen peroxide, 0.3 parts of sodium hydroxide; the mass ratio of hydrogen peroxide to water is 7:3;

[0041] 2) Immerse the completely faded peony flower heads in step 1) in the liquid phase substitute agent, and perform ultrasonic treatment at the same time; the power of the ultrasonic treatment is 60W, and the time of ultrasonic treatment is 30min; Take it out from the liquid phase substitute; the liquid phase substitute consists of the following components in mass percentage: citric acid 1%, sodium chlori...

Embodiment 26

[0058] The method for preparing immortal flowers by ultrasound-induced osmosis of the present embodiment comprises the following steps:

[0059] 1) Cut off the flower head of the peony flower, leave the flower diameter 3cm, put it in a decolorizing agent and soak it under airtight conditions for 4 hours until the peony flower fades completely; the decolorizing agent used is composed of water and the following components in parts by weight: ethanol 97 parts, 1.5 parts of hydrogen peroxide, 0.6 parts of sodium hydroxide; the mass ratio of water and hydrogen peroxide is 6:3;

[0060] 2) Immerse the completely faded peony flower heads in step 1) in the liquid phase substitute agent, and perform ultrasonic treatment at the same time; the power of ultrasonic treatment is 80W, and the time of ultrasonic treatment is 40min; Take it out from the liquid phase substitute; the liquid phase substitute consists of the following components in mass percentage: citric acid 2%, sodium chloride ...

experiment example 1

[0068] The tensile strength and puncture strength of the immortalized flowers prepared by the method for preparing immortalized flowers by ultrasonic infiltration in Examples 1-25 were respectively measured. The texture analyzer used is a model Instron5544Q6427 produced by Instron Corporation of the United States.

[0069] 1) The determination of the tensile strength adopts Chen Pengtao’s method: the petals with different treatments are cut into strips with a size of 20mm×5mm, and the thickness of the petals is measured with a spiral micrometer (6 different parts of the petals are measured respectively and the average value is taken). value), use a texture analyzer to measure the maximum tensile force that the petal can bear under the condition that the tensile speed is 1mm / s, and then calculate the tensile strength Y:

[0070] Y=F / (Δa×L);

[0071] In the formula: F is the maximum tensile force (N) that the petal can bear; L is the width of the petal (mm); Δa is the thickness...

Abstract

The invention relates to an ultrasonic permeation enhancing preparation method for a preserved fresh flower and a preserved fresh flower and belongs to the technical field of flowering branch chemicalpreservation. The ultrasonic permeation enhancing preparation method for the preserved fresh flower comprises the following steps of conducting decolorizing treatment on a fresh cut flower, then immersing the fresh cut flower into a liquid phase substitute for ultrasonic treatment, and drying. According to the ultrasonic permeation enhancing preparation method for the preserved fresh flower, thethermal motion of substitute molecules and water molecules can be quickened by the cavitation effect and heat effect of ultrasonic, therefore the disadvantage can be overcome that the power of insideand outside diffusion of the moisture in the flower when replacement is conducted in the normal condition; meanwhile, micro channels are formed on the surface of petal tissues and macromolecules in the liquid phase substitute is promoted to permeate into the micro channels for moisture replacement, so that the shrinking degree of the petals is effectively reduced; moreover, all the components in the liquid phase substitute is uniformly distributed in cell tissues, so that the overall preserved fresh flower is uniformly dyed, the flexibility of the petals is good, the preserved fresh flower ismoist, soft and good in soundness and the appearance form of the fresh cut flower is largely kept.

Description

technical field [0001] The invention relates to a method for preparing immortal flowers by ultrasonic infiltration and immortal flowers, and belongs to the technical field of chemical preservation of flower branches. Background technique [0002] Peony is a traditional precious flower in my country, with various varieties, rich colors, and high medicinal and ornamental value. Especially in recent years, with the rapid development of the peony industry, its planting scale has also been rapidly expanded, and it has become one of the pillars of agriculture and tourism in the planting area. However, peony planting is subject to large geographical restrictions, long cultivation cycle, short flowering period, difficulty in keeping fresh, and inconvenient long-distance transportation, resulting in high cost of peony industry, which greatly hinders market expansion. [0003] Preserved Fresh Flower (Preserved Fresh Flower) is a kind of dried flower product with continuous ornamental...
