Embodiment 1

[0007] Choose Cordyceps with normal appearance and color, no deterioration, and insect bites, wash, dry, and put them in the freezer for freeze-drying. When freeze-drying, first lower the temperature to 10°C, and then quickly drop the temperature to -130°C , when the pressure is less than 650mmHG, keep it for 20 minutes so that the moisture content is not higher than 10%, and then pulverize, the temperature during pulverization is not higher than 10°C, and the particles are between 300-400 mesh. Measure the effective content of the obtained powder, and the results are shown in the attached table.

Embodiment 2

[0009] Choose Cordyceps with normal appearance and color, no deterioration, and insect bites, wash, dry, and put them in the freezer for freeze-drying. When freeze-drying, first lower the temperature to -50 ° C, and then quickly drop the temperature to -100 ℃, vacuumize, when the pressure is less than 650mmHG, keep it for 20 minutes, so that the moisture content is not higher than 10%, and then pulverize, the temperature is not higher than 10℃ during pulverization, and the particles are between 300-400 mesh. Measure the effective content of the obtained powder, and the results are shown in the attached table.

Embodiment 3

[0011] Choose Cordyceps with normal appearance and color, no deterioration, and insect bites, wash, dry, and put them in the freezer for freeze-drying. When freeze-drying, first lower the temperature to -40°C, and then quickly drop the temperature to -120 ℃, vacuumize, when the pressure is less than 650mmHg, keep it for 30 minutes, so that the moisture content is not higher than 10%, and then pulverize, the temperature during pulverization is not higher than 10℃, and the particles are between 300-400 mesh. Measure the effective content of the obtained powder, and the results are shown in the attached table.

Abstract

The preparation method of cordyceps powder preparation is characterized by that when it is freeze-dried, firstly the temperation is reduced to 100 deg.C - -50 deg.C, then the temperature can be quickly reduced to -100 deg.C - -130 deg.C, and is retained for 20-30 min. to make its water content less than 10%, then it is pulverized. The effective component content contained in said cordyceps powder preparation is higher than that of cordyceps prepared by general method, so that the utilization rate of it medicinal material can be raised.

Description

technical field [0001] The invention relates to a preparation method of cordyceps powder. Background technique [0002] Cordyceps is a valuable Chinese herbal medicine, especially wild Cordyceps. The usual processing methods are drying in the sun or heating, and crushing at room temperature, which will cause the reduction of active ingredients such as enzymes and adenosine, and reduce the utilization rate of medicinal materials. Contents of the invention [0003] The technical problem to be solved by the invention is to reduce the loss of active ingredients in the processing process of Cordyceps sinensis and improve the utilization rate of medicinal materials. [0004] The technical scheme of the present invention is: select the Cordyceps sinensis with normal appearance and color, no deterioration and insect bites, wash and dry, put into the freezer for freeze-drying, and when freeze-drying, first lower the temperature to 10°C--50°C. ℃, and then quickly lower the tempera...
