Problems solved by technology

The anti-mold method in the prior art actually uses aminofructonic acid as a preservative to penetrate into the interior of Codonopsis pilosula. This operation method cannot solve the problem of moisture absorption of Codonopsis pilosula, and the inside of the medicinal material will also contain a large amount of aminofructonic acid due to the vacuum effect. Eating Codonopsis pilosula containing preservatives will cause harm to the human body. Therefore, it is urgent to provide a maintenance method for preventing insects and mildew of Chinese medicinal materials without using preservatives.

Embodiment 1

[0022] The present embodiment provides a kind of Chinese medicinal material conservation method, comprises the following steps:

[0023] Preparation of coating solution: Add 60 parts of 75% ethanol to 15 parts of zein, mix for 10 minutes at a stirring speed of 200 rpm / min, then add 8 parts of hydroxypropyl cellulose, 2 parts of glycerin and 0.3 parts of vitamin E in sequence , after stirring at 300rpm / min for 5min, remove the insoluble matter by filtration to obtain the coating solution.

[0024] Codonopsis pilosula is dried to a water content of 12.3%, and a layer of coating solution is evenly brushed on the surface of Codonopsis pilosula with a brush, dried at 40°C until there is no alcohol smell, and stored in a ventilated and dry place.

Embodiment 2

[0026] The present embodiment provides a kind of Chinese medicinal material conservation method, comprises the following steps:

[0027] Preparation of coating solution: Add 60 parts of 70% ethanol to 10 parts of zein, mix for 10 minutes at a stirring speed of 200 rpm / min, then add 10 parts of hydroxypropyl cellulose, 1 part of glycerin and vitamin E0.5 After stirring at 300rpm / min for 5min, the insoluble matter was removed by filtration to obtain the coating solution.

[0028] Codonopsis pilosula is dried to a water content of 12.8%, and a layer of coating liquid is evenly sprayed on the surface of Codonopsis pilosula with a sprayer, dried at 35°C until there is no alcohol smell, and stored in a ventilated and dry place.

Embodiment 3

[0030] The present embodiment provides a kind of Chinese medicinal material conservation method, comprises the following steps:

[0031] Preparation of coating solution: Add 80 parts of 60% ethanol to 20 parts of zein, mix for 10 minutes at a stirring speed of 200 rpm / min, then add 5 parts of hydroxypropyl cellulose, 3 parts of glycerin and 0.1 part of vitamin E , after stirring at 300rpm / min for 5min, remove the insoluble matter by filtration to obtain the coating solution.

[0032] Codonopsis pilosula is dried to a water content of 13.2%, and a layer of coating liquid is evenly sprayed on the surface of Codonopsis pilosula with a sprayer, dried at 45°C until there is no alcohol smell, and stored in a ventilated and dry place.

Abstract

The invention belongs to the technical field of processing of Chinese medicinal materials, and relates to a Chinese medicinal material curing method. The curing method comprises the following steps: (1) drying raw Chinese medicinal materials until a water content is 15% or less; and (2) coating the surfaces of the Chinese medicinal materials with a coating solution containing zein and hydroxypropyl cellulose, and drying. The hydroxypropyl cellulose and the zein are prepared into the coating solution, and 60-90% ethanol solution is used as a solvent, so that bacterial microbes on the surfaces of the Chinese medicinal materials can be killed by using the sterilization property of the ethanol while the coating solution is sprayed. After the ethanol is volatilized, a transparent and lustrous film can be formed on the surfaces of the Chinese medicinal materials, and the film has uniform and compact structure, low transmittance to water vapor and oxygen and strong mechanical properties, is moisture-proof and oxygen-resistant and can effectively reduce the problems of mildew and worm damage of the Chinese medicinal materials due to moisture absorption.

Description

technical field [0001] The invention belongs to the technical field of processing Chinese medicinal materials, and relates to a method for maintaining Chinese medicinal materials. Background technique [0002] The traits and components of Chinese herbal medicines are the main indicators for judging the quality of medicines. The storage and maintenance of Chinese herbal medicines directly affect the composition and properties of Chinese herbal medicines. The main factors that cause changes in the composition of Chinese herbal medicines include: the properties of medicinal materials, water content, bacterial contamination, and Appropriate storage temperature, exposure to air oxidation or sunlight. For Chinese herbal medicines with high sugar content, such as asparagus and Codonopsis pilosula, special attention should be paid to prevent mildew and insects caused by moisture absorption during the maintenance process. [0003] In Chinese patent 201610374898.8, a method for preve...
