At present, the processing of dried rose on the market is obtained by the original heating and baking process. Due to the higher heating temperature, the color of the flower buds becomes dark. In order to make the color bright, a few processing points are smoked with sulfur.

Red color, crystal clear, easy to transport and long-term storage, to maximize the preservation of its nutrition and health function.

Advantages of freeze-drying technology:

After drying, the biological active and effective ingredients of rose are destroyed very little, and the shape of rose is well preserved, which maintains the nutrition and active substances of rose, with low moisture content and high sugar content. Red color, crystal clear, easy to transport and long-term storage. Conform to hygienic requirements, maintain biological activity, color and flavor and aroma. Reduce the loss of volatile and heat sensitive material, can best maintain the original properties of the material. After drying volume and shape unchanged, good water rehydration. Not easy to oxidize, better preservation of goods, extend the shelf life. The analysis of modern high performance liquid chromatograph showed that the rose after lyophilization was compared with the rose after traditional drying. The content of anthocyanin in the roses produced by freeze-drying process is obviously higher than that of the roses produced by ordinary drying process on the market. No matter the color of the soaking solution of scented tea or the active ingredients of anti-oxidation and anti-aging in the tea, the freeze-dried roses have good appearance and high quality.
