Problems solved by technology

[0006] Using the existing technology for making other flowers and immortal flowers, the dehydration and decolorization solution mostly uses ethanol-based solution, a 1:1 mixture of methanol and ethanol, or a sucrose solution for dehydration and decolorization. Such a method is easy for eustoma Uneven dehydration and decolorization occur, or the petals of eustoma are too brittle and easy to be damaged, so that the next step cannot be carried out normally; and the liquid phase replacement solution often adds different proportions of glycerol (glycerin), which will make the petals thin. Bellflowers appear sticky, shrunken, transparent or excessively sagging

Embodiment 1

[0049] The preparation method of eustoma preserved flower comprises the following steps:

[0050] Rehydration treatment: select fresh cut flower eustoma, the variety is "Lusita", trim the stem to a length of about 15cm, immerse in saline, cut off the length of about 0.5cm (cut in water, isolate the air), and the final water level is at the height of the stem 1 / 2 of the stalk height, soak for 24 hours.

[0051] Dehydration and decolorization: Soak the eustoma flowers for 36 hours in a mixture of 75% methanol and 25% isopropanol by volume.

[0052] Liquid phase substitution: completely soak the dehydrated and decolorized eustoma flowers in a mixed solution of 60% absolute ethanol and 40% polyethylene glycol by volume within 1 minute, and soak for 24 hours.

[0053] Drying: Ventilate and dry the eustoma flowers after liquid phase substitution and dyeing at room temperature and normal pressure for 2 weeks.

Abstract

The invention relates to a preparation method of a preserved flower of eustoma grandiflorum. An adopted dehydration and decoloration solution is a mixed solution of methanol with the volume fraction of 48%-77% and isopropanol with the volume fraction of 23%-52%; and the liquid phase replaces a mixed solution of absolute ethyl alcohol with the volume fraction of 27%-60%, polyethylene glycol with the volume fraction of 38%-70% and pigment with the volume fraction of 0%-5%. The preserved flower of eustoma grandiflorum obtained by replacing and dyeing the eustoma grandiflorum flower with the dehydration and decoloration solution and the liquid phase is tough in texture, free of drooping and softening phenomena, attractive in appearance and uniform in color; and meanwhile, the manufacturing process is simplified, and the manufacturing time consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of preserved flower processing, in particular to a preparation method of Eustoma preserved flower. Background technique [0002] Eustoma grandiflorum (Raf.) Shinners is a perennial plant of the Gentianaceae Eustoma genus. It has a light plant shape and elegant and unique flower shape. It is one of the most popular cut flower species in the world. The vase period is only about two weeks, which is a suitable choice for making preserved flowers. [0003] Preserved flowers are also called preserved flowers, ecological flowers, and are also called "flowers that never fade" abroad. Eternal flowers are dried flowers made from fresh cut flowers such as roses, carnations, phalaenopsis, hydrangeas, etc., after dehydration, decolorization, drying and dyeing. . And it can not be affected by the season time, it is convenient to store and has a long ornamental period, which greatly improves the ornamental value and eco...
