In recent years, the traditional Chinese medicine (TCM) therapy has been popular around the world and Chinese herbal medicine powder has also been widely applied clinically. To ensure the safety of Chinese herbal powder, effective sterilization of the powder is an important measure. In this article, we will discuss the main sterilization methods of Chinese herbal medicine powder and the features of each method.
Generally, there are three main sterilization methods of Chinese herbal medicine powder, which are high-temperature sterilization, irradiation sterilization, and electronic beam sterilization.
High-temperature sterilization is the most commonly used sterilization method for Chinese herbal medicine powder. High-temperature sterilization is to heat the Chinese herbal medicine powder above 100℃ for several minutes, which can inactivate all the microorganisms in it. This sterilization method has the characteristic of simple operation, low cost and no residue.
Irradiation sterilization is also a common sterilization method for Chinese herbal medicine powder. In this method, ultraviolet light and/or X-ray are used to irradiate the powder for some time, which will lead to the death of most of the microorganisms. This method has the advantages of low energy consumption, convenience and short time required.
Electronic beam sterilization is a new technology applied to Chinese herbal medicine powder. In this method, high-energy electron beam will be used to hit the powder and produce strong oxidizing and ionizing power to kill the microorganisms. This method has the advantage of high sterilization efficiency.
When selecting the best sterilization method for Chinese herbal medicine powder, one should consider the characteristics of the powder itself. For example, high-temperature sterilization will cause some changes in Chinese herbal medicine powder, while radiation sterilization and electronic beam sterilization will not cause any changes. Therefore, the characterization of the powder should be taken into consideration to select the best sterilization method.
In conclusion, there are three main sterilization methods for Chinese herbal medicine powder, which are high-temperature sterilization, irradiation sterilization, and electronic beam sterilization. The selection of the appropriate sterilization method should be based on the characteristics of the powder itself.
