What is the shelf life of flower tea leaves

The shelf life of flower tea leaves is generally 12 to 24 months, which is affected by storage conditions, packaging methods, types of flower tea, processing techniques, and whether preservatives are added. The shelf life of flower tea is closely related to the storage environment. Unopened sealed packaging of flower tea can be stored for a long time in a cool and dry place, and avoiding light and moisture is key. If well preserved, common varieties such as jasmine tea and rose tea can maintain their aroma and color for a longer period of time. Vacuum packaging or aluminum foil inner bags can effectively isolate air and moisture, extending shelf life. High temperature and high humidity environments can accelerate the oxidation and mold growth of flower tea. It is recommended to consume it as soon as possible after opening. Flower tea with some natural preservatives added has a relatively longer shelf life, but the flavor may gradually weaken over time. The shelf life of freeze-dried flower tea or low-temperature baked products treated with special processes may vary slightly. chrysanthemum tea and other high sugar varieties are prone to moisture absorption and spoilage, so special attention should be paid to sealing. Bulk flower tea usually has a shorter shelf life than packaged products due to its higher exposure to air. Although some flower teas do not mold after being stored for a long time, their active ingredients and aromatic substances will be lost, and their drinking value will decrease. Industrial sterilized flower tea is more resistant to storage than traditional sun dried products, but may lose some active substances.

It is recommended to store flower tea in a sealed container and place it in a dark place to avoid contact with odorous objects. Seal it promptly after each use, and it can be paired with a desiccant to prevent moisture. Regularly check whether the flower tea is damp, clumped, discolored, or has a strange odor. Expired flower tea should not be continued to be consumed. Mixing different varieties of flower tea for storage may affect each other's flavor, so it is best to pack them separately. Observe the changes in soup color and aroma during brewing, and stop drinking immediately if there is turbidity or odor.
