Embodiment 1

[0012] Example 1. Freshly harvested Codonopsis Codonopsis after removing impurities such as leaves and soil, soaked in 5 mmol / L fructoaminoglyconic acid solution, and vacuumed the headspace of the solution to -0.08 MPa to maintain the Vacuum for 1 minute, take out the above medicinal materials, drain and expose to sunlight for 6 hours, and dry in the shade to normal storage moisture content.

Embodiment 2

[0013] Example 2. Soak Codonopsis Codonopsis, which is freshly harvested and removes impurities such as leaves and soil, in 6 mmol / L glucosamine solution, and vacuumize the headspace of the solution to -0.08 MPa, and maintain the vacuum Conditioned for 2 minutes, take out the above medicinal materials, drain and expose to sunlight for more than 4.5 hours, and dry to normal storage moisture content.

Embodiment 3

[0014] Example 3. Soak Codonopsis Codonopsis freshly harvested and remove leaves and soil and other sundries in 7 mmol / L glucosamine solution, and vacuumize the headspace of the solution to -0.075 MPa, and maintain the vacuum Conditioned for 2.5 minutes, take out the above medicinal materials, drain and expose to sunlight for 5 hours, and dry in the shade to the normal storage moisture content.

Abstract

The invention discloses an insect-proof and mildew-proof method for traditional Chinese medicine dangshen, which is used for solving the problems of mildewing and insect damage in the storage process of the traditional Chinese medicine dangshen after picking. The method comprises the following steps: soaking the picked traditional Chinese medicine dangshen in a 5-8 millimole / liter aminolevulinic acid solution, and vacuumizing the solution to 0.08-0.07MPa; maintaining the vacuum condition for 1-3 minutes; taking out the medicine, and draining off the medicine; irradiating the medicine with sunlight; and then drying the medicine in the shade. The method disclosed by the invention is simple, is convenient and easy to operate, and is relatively low in cost; and meanwhile, the aminolevulinic acid is a common natural ingredient in fruits and vegetables, is nontoxic, harmless and environment-friendly and has no side effect on the medicine dangshen in the characteristic parameters, thereby overcoming the obvious defects of the currently common technology which emphasizes the control of mildewing and insect damage from the downstream part.

Description

technical field [0001] The invention belongs to the field of post-harvest maintenance of Chinese medicinal materials, and in particular relates to an insect-proof and mildew-proof method of Chinese medicinal material Codonopsis pilosula. Background technique [0002] Codonopsis pilosula, a traditional Chinese medicine, is rich in carbohydrates, proteins, lipids and other biochemical components, and the polysaccharides and other substances in it are very easy to absorb moisture during storage due to their high hydrophilicity. Sufficient water after absorbing moisture makes the insect eggs on the surface of the medicinal material or in the environment hatch and grow, and the fungal spores germinate rapidly. Coupled with the appropriate temperature and the rich growth nutrients in the medicinal material, moths and spoilage microorganisms grow rapidly, causing a large area of ​​worms in the medicinal material. Moth and mildew. The population of moths increases rapidly, consumes...
