Problems solved by technology

Because sweet-scented osmanthus is rich in phenolic substances and is prone to browning during processing, domestic enterprises mostly use SO 2 Color protection brings safety hazards; in addition, osmanthus petals are thin and delicate. In the traditional dehydration drying process, if there is no proper pre-treatment for shaping and no fillers to replace the lost water in the flowers, it is easy to deform the flowers. , the quality and economic value of the product are seriously affected

Embodiment 1

[0021] The invention discloses a color-protecting and shaping process of dried osmanthus osmanthus flowers. The dried osmanthus osmanthus flowers are subjected to steam blanching, cooling, color-protecting and shaping treatments, and then dehydrated and dried with hot air at a second stage temperature to obtain dried osmanthus osmanthus products.

[0022] The concrete steps of described technique are as follows:

[0023] 1) Steam blanching: Osmanthus osmanthus flowers are evenly blanched with steam for 1 min;

[0024] 2) Cooling: quickly cool the flowers with flowing ice water after blanching;

[0025] 3) Color protection and setting treatment: After adding 5wt% glycerin and 0.50 wt% isovitamin C sodium salt in water, add food sourness regulator citric acid to adjust the pH to 4.5, and mix well to obtain the color protection and setting liquid; Osmanthus osmanthus was added with 10 times the quality of osmanthus osmanthus color-protecting and shaping liquid, and the color-pro...
