The preservation methods of dried cordyceps mainly include the following points:
1. Sealed storage: Place the dried cordyceps into a well sealed container, such as a glass bottle, metal can, or sealed bag, to reduce its direct contact with air and avoid moisture and oxidation. This is a key step in maintaining the freshness and quality of dried cordyceps.
2. Low temperature storage: If conditions permit, dried cordyceps can be stored in the refrigerator's refrigerated or freezer compartment. The temperature in the refrigerator should be controlled between 2-8 ℃, while the temperature in the freezer is even lower. Low temperature environment can effectively slow down the biological activity and microbial growth rate in Cordyceps sinensis, thereby extending its storage time.
3. Moisture and mold prevention: During the storage of dried cordyceps, attention should be paid to moisture and mold prevention. You can place some desiccants, such as silicone bags or dried tea leaves, in a sealed container to absorb any moisture that may enter the container. At the same time, it is necessary to regularly check the condition of the dried cordyceps to ensure that it is not damp, moldy, or infested with insects. If any problems are found, they should be dealt with promptly and the desiccant should be replaced.
The following points should also be noted:
Avoid direct sunlight: Cordyceps should be stored in a cool and shady place, away from direct sunlight to prevent damage to its active ingredients.
Regular inspection: Even if the above preservation measures are taken, the condition of dried cordyceps should be checked regularly. It is recommended to check at least once a month to ensure its quality and efficacy.
Avoid contamination: When storing and using dried cordyceps, be careful to avoid contamination. For example, do not mix dried cordyceps with harmful substances such as chemicals and pesticides.
By measures such as sealed storage, low-temperature storage, moisture and mold prevention, and avoiding direct sunlight and pollution, dried cordyceps can be effectively preserved and its storage time can be extended.
