Abstract

The invention discloses a method for preserving traditional Chinese medicinal materials by using dry ice, which includes the following steps: 1) a packing bag I is sequentially filled with the dry ice and the traditional Chinese medicinal materials, wherein the proportion of the dry ice and the traditional Chinese medicinal materials is that every 1 kg of traditional Chinese medicinal materials contain 5 to 20 g of dry ice; and 2) at least one packing bag I which is obtained in the step 1) and includes the contents of dry ice and traditional Chinese medicinal materials is placed into a packing bag II which is filled with the dry ice, the packing bag II is sealed after the filled dry ice is gasified and completely fill the packing bag I and the packing bag II, thereby accomplishing the operationof preserving the traditional Chinese medicinal materials by the dry ice, wherein the proportion ratio of the dry ice in the packing bag II to the traditional Chinese medicinal materials in each packing bag I is that every 1 kg of traditional Chinese medicinal materials contain 5 to 10 g of dry ice. The method for preserving the traditional Chinese medicinal materials has the advantages of simple and convenient operation, low production cost and high packing efficiency, can prevent the traditional Chinese medicinal materials from being damaged by storehouse insects, keeps the original colors of the traditional Chinese medicinal materials, has less influence on the quality of the traditional Chinese medicinal materials, is pollution-free, and can extend the shelf life of traditional Chinese medicine.

Description

technical field [0001] The invention relates to a method for storing Chinese medicinal materials, in particular to a method for storing Chinese medicinal materials with dry ice. Background technique [0002] The storage of traditional Chinese medicinal materials is an important link in the circulation process of traditional Chinese medicine. Preventing Chinese medicinal materials from being harmed by various pests during storage is an important factor to ensure the quality of Chinese medicinal materials. [0003] In order to prevent Chinese medicinal materials from being harmed by various warehouse insects during storage, a series of targeted insect control techniques have been formed, such as methods of adjusting appropriate temperature and humidity (Chen Li, Wang Jiyu: The relationship between storage and temperature of traditional Chinese medicine, Liaoning Journal of Traditional Chinese Medicine , 2004, 31(10): 873; Zhang Shenyou, Zhang Yan'e: Analysis on the storage of...
