Abstract

The invention provides a preparation method of dendrobium freeze-dried powder. The preparation method comprises the following steps: firstly, breaking walls of a dendrobium raw material by adopting an ultrahigh pressure low temperature technique; secondly, grinding the dendrobium raw material after the walls are broken into thick liquid and uniformly mixing, and carrying out vacuum freeze-drying, so that dendrobium powder is obtained, wherein the vacuum freeze-drying process concretely comprises that pre-freezing, primary sublimation and secondary sublimation are sequentially carried out on the dendrobium raw material after being ground into the thick liquid and uniformly mixed; and thirdly, carrying out superfine grinding on dendrobium powder. In the preparation method of the dendrobium freeze-dried powder, the ultrahigh pressure low temperature technique is adopted for breaking the walls, and the vacuum freeze-drying and the superfine grinding are combined, so that raw material utilization ratio is improved, the biological activity of functional substances in fresh dendrobium raw materials is hardly lost, and pharmaceutical values and health effects of the dendrobium raw materials are enhanced.

Description

technical field

[0001] The invention relates to the technical field of traditional Chinese medicine processing, in particular to a preparation method of dendrobium freeze-dried powder. Background technique

[0002] Fresh medicine refers to the medicine made by processing the whole or part of the tissue of fresh plants or animals, or taking its juice. The method of using fresh medicine is not only decoction, but also natural juice. In the "Compendium of Materia Medica" of the Ming Dynasty, there were more than 1,100 prescriptions using fresh herbs, and the application of fresh herbs in ancient times reached a peak. In modern times, due to the high cost of cultivation, storage and transportation of fresh medicine, and the limitation of processing technology, it is difficult to keep fresh medicine fresh, which limits its clinical application. develop. At present, dry products are mainly used to replace fresh medicines in clinical practice, and the traditional processing techn...

Examples

preparation example Construction

[0031] The invention provides a kind of preparation method of dendrobium freeze-dried powder, comprises the following steps:

[0032] Step 1, using ultra-high pressure and low temperature technology to break the wall of fresh dendrobium raw materials;

[0033] Step 2. After the fresh dendrobium raw material after the broken wall is refined and mixed, adopt vacuum freeze-drying to obtain dendrobium powder; the vacuum freeze-drying process specifically includes: pre-freezing the dendrobium raw material after refining and mixing , the first sublimation and the second sublimation;

[0034] Step 3, superfinely pulverizing the dendrobium powder.

[0035] The preparation method of the dendrobium freeze-dried powder of the present invention adopts ultra-high pressure and low temperature technology to break the wall, so that the cell wall and cell membrane of fresh dendrobium are cracked, the medicinal ingredients are fully released and the activity of the medicinal ingredients is mai...

Embodiment 1

[0056] A preparation method of dendrobium freeze-dried powder, comprising the following steps:

[0057] Step 1. Acceptance of dendrobium raw materials: Copper-skinned dendrobium is produced in Huaping County, Lijiang City, Yunnan Province, fresh dendrobium.

[0058] Step 2, selection and cleaning: select undamaged and mildew-free Dendrobium, and remove the leaves; then rinse the Dendrobium with pure water.

[0059] Step 3. Wall breaking: Ultra-high pressure and low temperature technology is used to crack the cell wall and cell membrane of Dendrobium, fully release the medicinal ingredients and maintain the activity of the medicinal ingredients, which can well protect the bright color of Dendrobium. The treatment conditions of the ultra-high pressure and low temperature technology are: put a certain volume of cold water in the ultra-high pressure container, the pressure of the container is 450MPa, the pressure is maintained for 1min, and the temperature is 60°C.

Embodiment 2

[0070] A preparation method of dendrobium freeze-dried powder, comprising the following steps:

[0071] Step 1. Acceptance of dendrobium raw materials: fresh dendrobium is produced in Ziyun County, Guizhou Province.

[0072] Step 2, selection and cleaning: select undamaged and mildew-free Dendrobium, and remove the leaves; then rinse the Dendrobium with pure water.

[0073] Step 3. Wall breaking: Ultra-high pressure and low temperature technology is used to crack the cell wall and cell membrane of Dendrobium, fully release the medicinal ingredients and maintain the activity of the medicinal ingredients, which can well protect the bright color of Dendrobium. The treatment conditions of ultra-high pressure and low temperature technology are as follows: a certain volume of cold water is placed in an ultra-high pressure vessel, the pressure of the vessel is 480MPa, the pressure is maintained for 2 minutes, and the temperature is 55°C.

[0074] Step 4, refining and mixing: use a r...
