PreservedFreshFlower is also called preserved flower, ecological flower, and abroad it is also called "flower that never fades". Preserved flowers are dried flowers made from fresh-cut flowers such as roses, carnations, phalaenopsis, and hydrangea, and processed through a series of complex processes such as dehydration, decolorization, drying, and dyeing.

Preserved flowers are almost the same as fresh flowers in terms of color, shape and feel. They maintain the characteristics of flowers, are richer in color, more versatile, and can be stored for at least 3 years. They are ideal for floral design and home use. The most ideal flower deep-processing product for decoration and celebration activities. Since its emergence in Germany in the last century, immortal flower products have been sought after by white-collar workers and upper-class consumers in Western countries. In 2012, "everlasting flowers" were very popular in the Japanese market, with a demand of at least 100 million flowers every year.

Introduction

In the process of making plant materials, the key to making dried flowers is whether they can preserve their original colors as much as possible and achieve the ideal viewing effect. From the perspective of color preservation methods, there are three basic methods of color preservation:

Physical color preservation method uses external environments such as temperature, humidity, light and oxygen content in drying media to maintain the color of plant materials. Bright color. The basic methods of physical color preservation include high temperature decompression color preservation method, low temperature decompression color preservation method and microwave drying color preservation method.

Chemical color preservation method is a color preservation method that maintains or changes the chemical structure and properties of the original pigments by chemically reacting with the pigments of the plant materials. Chemical color preservation methods are further divided into: color preservation of green materials, color preservation of colored flowers, and in vivo color absorption of flower leaves. Commonly used agents for color preservation include tartaric acid, citric acid, copper sulfate, aluminum sulfate, alum, tin chloride, zinc chloride, sucrose, etc.
