Vacuum freeze dryer: comparison of dried golden tea and freeze-dried flowers
Jinhuacha is one of the eight first-grade protected plants in the country. It is a kind of medicine and dietary material. It is suitable for all ages. Golden Camellia contains more than 400 kinds of trace elements which have important health effects on human body such as natural organic selenium, antimony, molybdenum, vanadium and zinc. It contains no caffeine and is naturally free of insects. The content of saponins and flavonoids is high in all tea plants, and its plant flavonoids are 11.47 times that of ginseng. It has wonderful effects on improving human immunity, anti-oxidation and repairing damaged cells! The obvious effect is to promote sleep.
After the golden flower tea blooms, the fresh golden tea flowers have high nutritional value, and some growers themselves eat fresh golden tea flowers. The fresh Camellia flower is not treated or cooked. First, it is difficult to release the nutrients of the golden tea without the treatment of the light. Second, the surface of the fresh flower is not treated with high temperature. Both can solve these two problems. There is a difference between the fresh golden scented tea and the dried golden scented tea. After the boiled tea is boiled, the golden broth will first appear. With the decrease of temperature, the golden scented tea broth will slowly change from golden yellow. red.
Fresh flower tea is certainly good, but the origin of Jinhuacha is only in Guangxi and the world. It is very difficult for others to drink fresh golden tea. In order to allow more people to drink golden tea, the golden tea is usually treated by freeze-drying or drying.
First, the golden flower tea is baked and dried. The drying method: high temperature treatment can easily lead to the loss of nutrient active ingredients of Jinhua tea. At the high temperature, the cell wall of Camellia sinensis will be destroyed, which will lose the nutritional value of Camellia sinensis, resulting in color change and flower pattern shrinking.
Drying golden tea
2. Golden flower tea freeze-dried is a golden tea lyophilized by a vacuum freeze dryer at low temperature. It not only retains the original color, odor, size and nutrient active ingredients of the golden flower tea, but also the microstructure of the golden tea after lyophilization. It is porous and easy to brew to release the nutrients of the flower tea.

How is freeze-dried golden tea made? In fact, it can be divided into three parts: 1. preliminary preparation, 2. low temperature pre-freezing, 3. vacuum freeze-drying. The preliminary preparation is to prepare the equipment properly, pick up the fresh Camellia flower, and also carry out a series of preliminary work on the selection and cleaning of the Camellia tea; the low temperature pre-freezing is to freeze the ice in the fresh golden tea at minus 40 degrees. Then lyophilize under vacuum.
