Embodiment 1

[0019] 1. Select 6 high-quality, disease-free roses and keep only the flowers.

[0020] 2. Dissolve 20 grams of magnesium chloride and 20 grams of citric acid in 160 mL of distilled water to prepare a 20% mixed solution of magnesium chloride and citric acid, package it, fill it with nitrogen, avoid contact with air, and store it away from light.

[0021] 3. Soak the selected roses in the mixed solution of magnesium chloride and citric acid for 5 hours.

[0022] 4. Take out the soaked flowers and put them on a dry and clean glass plate in a ventilated place to dry.

[0023] 5. Put the dried flowers into the solar dryer, adjust the temperature of the dryer to 50-60°C until the water on the surface of the flower is basically dried, and then take it out.

Embodiment 2

[0025] 1. Select 6 high-quality, disease-free roses and keep only the flowers.

[0026] 2. Mix and dissolve 20 grams of sucrose and 20 grams of citric acid in 160 mL of distilled water to prepare a mixed solution of sucrose and citric acid with a concentration of 20%, package it, fill it with nitrogen, avoid contact with air, and store it away from light.

[0027] 3. Soak the selected rose flowers in the prepared solution for 4.5 hours.

[0028] 4. Take out the soaked flowers and put them on a dry and clean glass plate in a ventilated place to dry.

[0029] 5. Put the dried flowers into the solar dryer, adjust the temperature of the dryer to 50-60°C until the water on the surface of the flower is basically dried, and then take it out.

Embodiment 3

[0031] 1. Select 6 high-quality, disease-free roses and keep only the flowers.

[0032] 2. Dissolve 30mL of glycerin and 20% magnesium chloride solution in 140mL of distilled water to prepare a mixed solution of 30% glycerin and magnesium chloride, package it, fill it with nitrogen, avoid contact with air, and store it away from light.

[0033] 3. Soak the selected rose flowers in the prepared solution for 4 hours.

[0034] 4. Take out the soaked flowers and put them on a dry and clean glass plate in a ventilated place to dry.

[0035] 5. Put the dried flowers into the solar dryer, adjust the temperature of the dryer to 50-60°C until the water on the surface of the flower is basically dried, and then take it out.

Abstract

The invention relates to a chemical color-retaining method for dried rose flowers. The method comprises the specific preparation steps and the optimal soaking time that 20 g of magnesium chloride and20 g of citric acid are taken and dissolved in 160 mL of distilled water so as to prepare a magnesium chloride and citric acid mixed solution with the concentration of 20%, and fresh flowers are soaked in the mixed solution for 5 hours; 20 g of sucrose and 20 g of citric acid are taken and dissolved in 160 mL of distilled water so as to prepare a sucrose and citric acid mixed solution with the concentration of 20%, and the fresh flowers are soaked in the mixed solution for 4.5 hours; 30 mL of glycerol and 30 mL of a magnesium chloride solution with the concentration of 20% are taken and dissolved in 140 mL of distilled water so as to prepare a glycerol and magnesium chloride mixed solution with the concentration of 30%, and the fresh flowers are soaked in the mixed solution for 4 hours. According to the method, rose petals treated by three chemical color-retaining reagents can keep fadeless for a long time under natural conditions after being dried by a solar drier, the color of the rose petals is basically the same as the primary color or is very small in change, and therefore a very high utilization value is achieved.

Description

technical field [0001] The invention relates to a chemical color preservation method for dried rose flowers, which belongs to the field of plant color preservation. Background technique [0002] Dried flowers, also known as dried flowers and immortal flowers, are a new type of ornament that has emerged in recent years. They are plant products with high ornamental value made of fresh plant materials after drying, color retention, and shaping. After the rose flowers dry naturally, their color and pattern will change. This has a lot to do with changes in the internal environment of the petal cells, external pressure, and differences in the pigments contained in the petals. The chemical color retention of flower color is mainly through changing the pH value of the flower material cells, complexing with metal ions, and using color retention agents to promote the formation of colloidal state in the cells, so as to increase the stability of the pigment and reduce the drying proces...
