brief introduction
In the process of making plant materials, whether the original color can be preserved as much as possible to achieve the ideal ornamental effect is the key to making dried flowers. There are three basic color-preserving methods:
Physical color protection method keeps the bright colors of plant materials by controlling the external environment such as temperature, humidity, light and oxygen content in dry media. The basic methods of physical color protection include high temperature decompression, low temperature decompression and microwave drying.
Chemical color protection is a kind of color protection method to maintain or change the chemical structure and properties of the original pigment through the chemical reaction between chemicals and pigments of plant materials.
