Red Chinese rose drying and color retaining process

Abstract

The invention discloses a red Chinese rose drying and color retaining process. Petals are laid on drying plates with good water absorption capability and placed into a special specimen holder, air permeability can be enhanced by drilling a certain number of holes in the specimen holder, a thin foam sponge is placed on each drying plate, water vapor release is facilitated, and then the special specimen holder is compressed by screws, placed into a sealed plastic container and dried for 2 to 3 days. The sponge is dipped in prepared color retaining liquid with different concentrations, the colorretaining liquid is applied to surfaces of flowers, reaction time is recorded when original colors are restored, redundant solution is absorbed by absorbent paper, and finally, the pedals are dried inthe drying plates for one day and then preserved. The pedals are neutral, unstable in pigments and easily changed into purple, the prepared color retaining liquid is applied to the dried pedals, metal magnesium ions in the color retaining liquid are complexed with anthocyanin to form anthocyanin, so that the pigments are stable, acid solution serves as a reducing agent to adjust internal acidityand alkalinity, the pedals are internally acid, and the original colors are restored.

Description

Technical field: [0001] The invention relates to a dry flower color retention process, in particular to a red rose drying color retention process. Background technique: [0002] Dried flowers are ornamental flower materials formed by physical or chemical treatment using natural plant materials. Petal color preservation is to use physical methods, chemical methods and physical and chemical methods to change the physical and chemical properties of the pigments and metal ions inside the petals to maintain the color of the petals for a long time. [0003] Dried flowers are very popular in western countries, consumers are increasing day by day, and the market is expanding day by day. Decorating and beautifying life with dried flowers has become a fashion pursuit of people all over the world. The sales of dried flowers are getting higher and higher. [0004] The research, development and commercialization of dried flowers in my country began in the 1980s. After more than 30 year...

AI Technical Summary

Problems solved by technology

[0009] The image of rose itself is relatively good, and the color and luster are relatively bright, so we carry out color preservation for rose flowers. However, because the pigment of rose petals is unstable, pretreatment and drying are difficult, so there are few studies in this area, and the process is also poor. It is relatively immature, and some key links need to be broken through, and the color retention of rose petals needs further research
