Cold storage storage methods for Chinese herbal medicines

　　The storage of Chinese herbal medicines is essential to maintain their quality and efficacy. This article will introduce the methods and some precautions for cold storage storage of Chinese herbal medicines to ensure that Chinese herbal medicines remain in the best condition during storage.

　　1. Temperature and humidity control:

　　Temperature control: The cold storage temperature of Chinese herbal medicines should be controlled within a suitable range, usually recommended to be between 5°C and 25°C. Too high a temperature will cause Chinese herbal medicines to deteriorate and deteriorate in quality, while too low a temperature may damage some Chinese herbal medicines. Check and record the temperature of the cold storage regularly to ensure temperature stability and consistency.

　　Humidity control: Chinese herbal medicines are sensitive to humidity, so the humidity of the cold storage also needs to be controlled. Humidity control between 50% and 70% is more appropriate. Too high humidity may cause Chinese herbal medicines to mold and damp, while too low humidity may cause Chinese herbal medicines to lose moisture. Use a hygrometer to monitor the humidity level and take necessary measures to adjust the humidity, such as using a humidifier or dehumidifier.

　　2. Ventilation and odor control:

　　Ventilation control: Good ventilation helps to maintain air circulation in the cold storage and prevent Chinese medicinal materials from generating odor or being polluted by harmful gases in the environment. Ensure that the ventilation facilities in the cold storage are operating normally, and clean the vents and filters regularly to maintain air quality and circulation.

　　Odor control: Chinese medicinal materials have a unique odor and are easily affected by external odors. Therefore, the cold storage should be separated from other items that may produce odors to avoid the influence of odors on Chinese medicinal materials. Some adsorbents or air fresheners can also be used in the cold storage to absorb odors.

　　3. Packaging and sealing:

　　Packaging selection: Chinese medicinal materials should be properly packaged before storage. Generally speaking, it is a common practice to use dry, odorless food-grade plastic bags or sealed containers to package Chinese medicinal materials. The packaging should have the functions of moisture-proof, rodent-proof and light-blocking.

　　Sealing performance: Ensure that the packaging of Chinese medicinal materials is well sealed to prevent the entry of moisture, oxygen and odor. Use appropriate sealing tools and methods to ensure the sealing performance of the packaging bag or container.

　　4. First-in-first-out principle:

　　In order to maintain the freshness and safety of Chinese medicinal materials, the first-in-first-out principle should be followed. When storing Chinese medicinal materials, ensure that fresh Chinese medicinal materials are placed in the back row and old Chinese medicinal materials are placed in the front row so that the old Chinese medicinal materials can be used earlier. This helps to avoid the expiration or deterioration of Chinese medicinal materials and minimize waste.

　　5. Regular inspection and maintenance:

　　The equipment and facilities of the cold storage need to be inspected and maintained regularly to ensure their normal operation and effectiveness. This includes checking the thermometer, hygrometer, ventilation system, sealing performance, etc. of the cold storage. Regular maintenance and cleaning are carried out to ensure the hygiene and function of the cold storage.

　　By controlling the above key points, the cold storage storage of Chinese medicinal materials will be more scientific and efficient. Reasonable temperature and humidity control, good ventilation and odor control, proper packaging and sealing, following the first-in-first-out principle, and regular inspection and maintenance will help maintain the quality and efficacy of Chinese medicinal materials and extend their shelf life. This is essential for providing safe, fresh and high-quality Chinese medicinal materials.
