Huoshan yellow bud storage method
Storage method
1. Dry storage: Tea has strong hygroscopicity. When the water content is high, it is susceptible to oxidative deterioration and mold deterioration. Therefore, the tea must be dried and stored. The storage container must be filled with an appropriate amount of hygroscopic agent such as lime or dry charcoal to prevent return of moisture.
2, low temperature storage: tea in the low-temperature qualitative change is slow, high temperature is easy to degenerate. Therefore, the tea must be stored in a low-temperature ventilated place, and the tea-filled container can be sealed in a refrigerator or in a cold storage.
3, moisture storage: moisture-proof packaging is the use of excellent moisture-proof packaging materials and adding desiccant to prevent tea water absorption packaging method.
4, dark storage: Infrared light will warm the tea, ultraviolet light will cause photochemical effect, thereby accelerating tea qualitative change. Therefore, we must avoid storing tea under strong light, but also avoid packaging tea with light-transmitting materials; for example, using glass bottles or translucent food bags to store tea leaves should be selected as a brown tea.
5, sealed storage: oxidation reaction is the essential process of tea qualitative change, if you cut off the oxygen supply can prevent oxidation inhibition of qualitative change. Therefore, it is necessary to seal the stored tea with oxygen.
6, vacuum storage: vacuum packaging and storage is the use of vacuum packaging machine, the tea bag air immediately after the pumping seal, so that the vacuum bag bag to form a state, so as to retard the oxidation of tea leaves, to achieve the purpose of preservation.
7, storage alone: ​​tea has a very strong adsorption properties, such as with camphor, gasoline together, can immediately adsorb the gas. Therefore, tea should be stored separately. Containers containing tea leaves must not be mixed with other items.
8, nitrogen storage: that is, using inert gas carbon dioxide or nitrogen to convert the tea packaging bag is very active oxygen and other air, blocking the chemical composition of tea and oxygen reaction, to prevent tea aging and deterioration.
