Embodiment 1

[0032] Soak the fresh root slices of the traditional Chinese medicine in an ethanol solution with a mass concentration of 25% for 5 minutes, then rinse with deionized water, and air-dry the surface water after rinsing to obtain the pretreated fresh root slices.

[0033] Transfer the pretreated air-dried slices to an airtight container for sterilizing treatment. In this embodiment, the sterilizing treatment adopts ultraviolet irradiation, wherein the ultraviolet intensity is 180 μW / cm 3 , the irradiation distance is 0.8m, and the irradiation time is 1h. After the sterilization treatment is completed, the airtight container is evacuated, and a fresh-keeping gas is introduced therein so that the airtight container includes: 97% CO by mass percentage 2 , with a mass percentage of 2.3% H 2 and 0.3% H by mass 2 O and other trace impurity gases. After feeding the fresh-keeping gas, the pressure in the airtight container is 1.5 times of the external pressure, and the airtight conta...

Embodiment 2

[0035] Soak the fresh root slices of the traditional Chinese medicine in an ethanol solution with a mass concentration of 45% for 1 min, then rinse with deionized water, and air-dry the surface water after rinsing to obtain the pretreated fresh root slices.

[0036]Transfer the air-dried slices after pretreatment to an airtight container for sterilization treatment. In this embodiment, the sterilization treatment adopts ultraviolet irradiation, wherein the ultraviolet intensity is 210 μW / cm 3 , the irradiation distance is 1.2m, and the irradiation time is 5h. After the sterilization process is completed, the airtight container is evacuated, and fresh-keeping gas is introduced into it, so that the airtight container includes: 93% CO by mass percentage 2 , with a mass percentage of 6.7% H 2 and 0.7% H by mass 2 O and other trace impurity gases. After feeding the fresh-keeping gas, the pressure in the airtight container is 2 times of the external pressure, and the airtight con...

Embodiment 3

[0038] Soak the fresh root slices of the traditional Chinese medicine in an ethanol solution with a mass concentration of 30% for 2 minutes, then rinse with deionized water, and air-dry the surface water after rinsing to obtain the pretreated fresh root slices.

[0039] Transfer the pretreated air-dried slices to an airtight container for sterilization treatment. In this embodiment, ultraviolet irradiation is used for sterilization treatment, and the ultraviolet intensity is 200 μW / cm 3 , the irradiation distance is 1m, and the irradiation time is 2h. After the sterilization process is completed, the airtight container is evacuated, and fresh-keeping gas is introduced into it, so that the airtight container includes: CO with a mass percentage of 94%. 2 , with a mass percentage of 3% H 2 , with a mass percentage of 0.4% H 2 O and methane with a mass percentage content of 2.6%. After feeding the fresh-keeping gas, the pressure in the airtight container is 1.6 times of the ext...

Abstract

The invention relates to the field of traditional Chinese medicine preparation, and provides a fresh-keeping method for a traditional Chinese medicine fresh root slice. The fresh-keeping method comprises the following steps: soaking a prepared traditional Chinese medicine fresh root slice in an ethanol solution with the mass concentration being 25-45% for 1-5 min, washing with deionized water, airing surface moisture, and obtaining a fresh root slice after pretreatment; placing the fresh root slice after pretreatment in a closed container, and performing sterilization; after sterilization, introducing fresh-keeping gas into the closed container, and enabling gas in the closed container to include: CO2 with the mass percentage being 93-97%, H2 with the mass percentage being 2.3-6.7%, and H2O with the mass percentage being 0.3-0.7%. The method has a good fresh-keeping effect on the traditional Chinese medicine fresh root slice. The invention further provides the traditional Chinese medicine fresh root slice after fresh-keeping treatment which is obtained by adopting the fresh-keeping method for the traditional Chinese medicine fresh root slice; the traditional Chinese medicine freshroot slice after fresh-keeping treatment is relatively high in freshness, and losses little pesticide effect.

Description

technical field [0001] The invention relates to the field of preparation of traditional Chinese medicines, in particular to a fresh-keeping method for fresh root slices of traditional Chinese medicines and fresh-keeping fresh root slices of traditional Chinese medicines. Background technique [0002] Chinese medicinal materials not only contain alkaloids, vegetable proteins, glycosides, and volatile oils, but also starch, fat, sugar, amino acids, organic acids, cellulose, tannins, and inorganic elements. Lost or changed during processing, etc. The most effective part of most traditional Chinese medicines is in the root, and it is a common practice for most medicinal material companies to slice the root. However, due to the immaturity of the existing technology, fresh root slices of traditional Chinese medicine are difficult to preserve, which leads to the fact that most of the slices circulating on the market are After drying and processing, the efficacy of dried and proces...
