Problems solved by technology

The active ingredients and taking effect of Chinese medicinal materials produced by modern drying technology are quite different from those produced by traditional technology, so the relative proportions of various medicinal materials are also changed, which affects the efficacy
Therefore, under the premise of ensuring that the active ingredients of Chinese medicinal materials are basically not lost, the content of active ingredients of medicinal materials that are naturally dried can also be kept basically the same, which cannot be achieved by commonly used hot air drying and freeze drying.
[0004] In the drying process of traditional Chinese medicinal materials, generally the milder the drying conditions, the smaller the loss of index components during the drying process, the shorter the disintegration time of the product, and the better the effect of taking. Natural drying is a good preparation method, and its energy consumption Low, the nutritional content is well preserved; but the natural drying method will be restricted by the weather and inconvenient to manage

Embodiment 1

[0033] In December-February, select 3-7-year-old, fresh, pest-free Dendrobium officinale, trim and remove the roots and leaves on the stem to obtain fresh Dendrobium strips, wash them, soak them in 1% citric acid solution for 30 minutes, and wash them with water . The dendrobium candidum that cleans is cut off again, and cut length is 5-10cm, and the mass concentration with L-cysteine ​​is 0.5%, the mass concentration of D-isoascorbic acid is the mixed solution of 2.0%, soaks 2 hours, is placed in Ventilated place for 2 days. Then place the Dendrobium candidum in an oven to dry, the drying temperature is 30° C., the flow rate of the airflow during drying is 10 m / s, and the drying time is 5 days until the moisture content of the Dendrobium candidum is lower than 10%, and the dried product of the Dendrobium candidum is obtained.

Embodiment 2

[0035] In December-February, select 3-7-year-old, fresh, pest-free Dendrobium officinale, trim and remove the roots and leaves on the stem to obtain fresh Dendrobium strips, wash, soak in 1.5% citric acid solution for 20 minutes, and rinse with water . The dendrobium candidum that cleans is cut off again, and the cutting length is 5-10cm, and the mass concentration with L-cysteine ​​is 1.0%, the mass concentration of D-isoascorbic acid is the mixed solution of 1.0%, soaks 2 hours, is placed in 2 days in a cool and ventilated place. Then place the Dendrobium candidum in an oven to dry, the drying temperature is 25° C., the flow rate of the airflow during drying is 10 m / s, and the drying time is 7 days, until the moisture content of the Dendrobium candidum is lower than 10%, and the dried product of the Dendrobium candidum is obtained.

Embodiment 3

[0037] In December-February, select 3-7-year-old, fresh, pest-free Dendrobium officinale, trim and remove the roots and leaves on the stem to obtain fresh Dendrobium strips, wash them, soak them in 2% citric acid solution for 5 minutes, and wash them with water . The dendrobium candidum that cleans is cut off again, and the cutting length is 5-10cm, and the mass concentration with L-cysteine ​​is 2.0%, the mass concentration of D-isoascorbic acid is the mixed solution of 0.5%, soaks 2 hours, is placed in 2 days in a cool and ventilated place. Then place the Dendrobium candidum in an oven to dry, the drying temperature is 23° C., the flow rate of the airflow during drying is 10 m / s, and the drying time is 12 days, until the moisture content of the Dendrobium candidum is lower than 10%, and the dried product of the Dendrobium candidum is obtained.

Abstract

The invention belongs to the field of traditional Chinese medicine processing, and discloses a method for preparing a dried product of Dendrobium candidum, comprising the following steps: (1) soaking Dendrobium candidum in citric acid solution, and cutting off; (2) treating the iron skin obtained in step (1) Dendrobium candidum is soaked in a mixed solution containing L-cysteine ​​and D-erythorbic acid, and placed; (3) drying the obtained Dendrobium candidum in step (2) to obtain a dried product of Dendrobium candidum; drying in step (3) The temperature is 23‑36 °C. The polysaccharide content of the obtained Dendrobium officinale dried product is as high as 30.4%, the mannitol content can reach 12.1%, the total amount of amino acids can reach 6.5g / 100g, and the total flavonoids can reach 2.1×10 2 mg / 100g, the chlorophyll is as high as 1.38mg / g, which is basically consistent with the product obtained by natural drying, and does not cause browning. The preparation method is simple to operate, not affected by the weather, and has low energy consumption.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine processing, and in particular relates to a preparation method of a dried dendrobium officinale product. Background technique [0002] Dendrobium candidum is sweet in taste and slightly cold in nature. It has the functions of promoting body fluid and nourishing stomach, nourishing yin and clearing heat, moistening lung and kidney, improving eyesight and strengthening waist, and lowering blood sugar. It has high medicinal value and is an important traditional Chinese medicine ingredient. [0003] Because the formula of traditional Chinese medicine is obtained by the predecessors using natural dried medicinal materials, on the basis of repeated experiments and repeated summarization of experience and lessons, the amount of active ingredients contained in various medicinal materials and the relative proportion of various medicinal materials are very particular. . The active ingredients and...
