Traditional Chinese medicine decoction piece of caulis dendrobii powder and preparation method thereof

Abstract

The invention relates to the technical field of processing Chinese herbal medicines, in particular to a traditional Chinese medicine decoction piece of caulis dendrobii powder and a preparation methodthereof. The preparation method includes the following steps of washing, draining and air-drying fresh caulis dendrobii to obtain pretreated caulis dendrobii; placing the pretreated caulis dendrobiiin ozone water for ozone sterilization; washing sterilized caulis dendrobii, and then adding purified water for wet pulverization to obtain a caulis dendrobii slurry; adding a composite enzymatic hydrolysis agent to the caulis dendrobii slurry for enzymatic hydrolysis to obtain an enzymatic slurry, and then conducting ultrasonic wave wall breaking treatment; conducting vacuum filtration to the enzymatic slurry subjected to ultrasonic wave wall breaking treatment to obtain a filtered caulis dendrobii slurry; conducting vacuum decompression concentration on the filtered caulis dendrobii slurry to obtain a concentrated caulis dendrobii slurry; conducting vacuum freezing drying on the concentrated caulis dendrobii slurry to obtain the traditional Chinese medicine decoction piece of caulis dendrobii powder. The preparation method has a good sterilization effect, less loss of active ingredients, high production efficiency and low production energy consumption, and is advantageous for industrialized large-scale production; the traditional Chinese medicine decoction piece has a high utilization rate, is easy to absorb and utilize, and has a long shelf life.

Description

technical field [0001] The invention relates to the technical field of processing Chinese medicinal materials, in particular to a dendrobium powdered Chinese medicinal decoction piece and a preparation method thereof. Background technique [0002] Dendrobium is a cultivated product of Dendrobium nobile, Dendrobium chrysalis or Dendrobium fringe and the fresh or dried stems of similar species of the same plant, which has the effects of nourishing stomach and promoting body fluid, nourishing yin and clearing heat. It is often used for fluid injury due to febrile disease, dry mouth and polydipsia, insufficient stomach yin, lack of food and retching, persistent asthenia heat after illness, hyperactivity of fire due to yin deficiency, bone steaming and labor heat, dark eyesight, muscle and bone flaccidity and softness, and has a high medicinal value.

[0003] However, Dendrobium contains a lot of nutrients, which can easily become a breeding ground for bacteria, affecting the shelf life and medicinal value of Dendrobium

In the prior art, the dendrobium is usually crushed first and then sterilized, but because the powdered medicine is not easy to transfer, it is easy to cause a lot of losses in the follow-up tedious sterilization steps, which increases the production cost in a disguised form; at the same time, The existing dendrobium powder cannot effectively utilize its active ingredients, resulting in low utilization rate of dendrobium, low absorption and utilization rate of human body, and short shelf life
