Preservation method
Edible roses only bloom once a year, and the flowering period is about 20 days. How to process, store for a long time and supply all the year round is a difficult problem. At present, the processing technology is still in the state of dried flower buds. The processing methods of dried flower buds mainly include shade drying and sun drying. The most valuable thing about roses is the volatile substances they contain. However, dry bud processing, whether it is dry in the shade or quick-drying, only keeps the original shape of rose buds. 90% of the effective substances volatilize during the drying process, and a large number of effective substances will volatilize. After processing, dried buds have lost most of their original health care and beauty values.
