preparation example Construction

[0021] The embodiment of the present invention discloses a method for preparing thermochromic preserved flowers, comprising the following steps: step a) soaking the fresh cut flowers in a dehydrating agent added with a desiccant for 20 to 30 hours, the dehydrating agent being ethanol, One or more of n-butanol, tert-butanol, acetone and glycerin; step b) soaking the fresh cut flowers in successively increasing concentrations of permeate, the mass concentration of the permeate is 20% to 70%, the soaking time each independently for 2 to 3 hours, after drying, thermochromic preserved flowers are obtained, and the penetrating liquid is composed of a chromogenic agent, a chromogenic agent, a temperature control agent and a low boiling point solvent, and the chromogenic agent, chromogenic agent and control agent The mass ratio of the warming agent is 1:1-200:10-200.

[0022] As a preferred solution, before soaking the fresh cut flowers in the present invention, the fresh cut flowers ...

Embodiment 1

[0036] The fresh-cut flowers selected in this embodiment are white gardenias.

[0037] A thermochromic preserved flower, the preparation steps of which are as follows:

[0038] After the fresh cut flowers are washed with water and sorted, soak them in ethanol with a small amount of molecular sieve for 24 hours to remove the interstitial fluid in the cut flowers;

Abstract

The invention provides a method for preparing thermochromic preserved flowers. The method includes the steps that cut fresh flowers are soaked in dehydrating agents for 20-30 hours, wherein drying agents are added into the dehydrating agents; the cut fresh flowers are sequentially soaked in penetrating fluid with increasing concentration, the mass concentration of the penetrating fluid is 20%-70%, and the thermochromic preserved flowers are obtained after dried. The penetrating fluid adopted in the method is composed of colorants, color developing agents, temperature control agents and low boiling point solvents. When the temperature changes, electron transferring happens between the colorants and the color developing agents along with fusion and solidification of the temperature control agents, so molecular structures of the colorants are changed, and a reversible thermochromic phenomenon happens. The method selects the low boiling point solvents, so the viscosity of the penetrating fluid in the penetrating process can be reduced, the colorants, the color developing agents and the temperature control agents can penetrate into flower cells beneficially, and the low boiling point solvents can be volatilized thoroughly in the drying process and will not affect a change color system. Accordingly, the preserved flowers prepared through the method can achieve a thermochromic effect and can be preserved for a long time.

Description

technical field [0001] The invention relates to the technical field of preserved flowers, in particular to a method for preparing thermochromic preserved flowers. Background technique [0002] Flowers are beautiful and fragrant, have great ornamental value, can beautify the environment and delight the mood, and are widely loved by people. For a long time, people have dreamed that flowers will always be fresh and beautiful, always blooming and undefeated. [0003] Recently, processed flowers called preserved flowers have attracted attention. Preserved flowers use organic preservation liquid to replace the moisture of plants, which can completely maintain the tissue and water of flowers, and can maintain the softness, freshness and beautiful posture of flowers for a long time without watering. Finally, the flowers can have nearly a hundred kinds of bright colors. [0004] Preserved flowers and their preparation methods have been extensively studied. Among them, the Chinese ...
