The storage and preservation of tea are crucial to the quality of tea. The methods of tea preservation can be roughly divided into six categories. But these six kinds also have their own advantages and disadvantages to be selected according to their own environment.
The method of keeping tea fresh is generally nothing more than the following:
1. Tea packaging materials have no peculiar smell and have good moisture-proof performance. The tea containers and methods of use should be sealed as close as possible to reduce contact with the air, and stored in a dry, clean and non-odorous place.
2. Ordinary bottles, canisters, etc. are used to store tea leaves. It is better to use double-covered inner and outer lids or a pottery jar with a large belly to reduce air contact in the container. The cover of the container must be tightly integrated with the container body to prevent moisture.
3. If there are conditions, the tea leaves in the iron can be evacuated to remove the air from the can by an air extractor, and then welded and sealed, so that the tea can be stored for two or three years. The outside air is isolated, and the tea leaves are packed into the gallbladder. After the plugs are tightly sealed, they are sealed with white wax and covered with plastic tape.
4. Use the refrigerator to store, pay attention to seal the tea before storage.
5. Using the thin air in the tank and the principle that the tea in the tank is sealed from the outside after sealing, the tea is dried until the water content is about 2%, and it is immediately filled into the tank while it is hot, then sealed, and can be stored for one or two years at room temperature.
6. Use quick lime or advanced desiccant, such as silica gel to absorb the moisture in the tea leaves, and the preservation benefit is better. The method is to seal the quicklime with a double white cloth, and then wrap the tea leaves in thin craft paper, and tie the wrapped tea leaves and the sealed lime into the altar at a ratio of 6.5: 1. Or in the middle of the barrel, then cover the altar with craft paper and a straw pad, and put it in a dry room for storage. When the lime absorbs moisture and the weathering degree reaches 80%.
It should be replaced in time. Generally speaking, new tea needs to be replaced once every two or three months. When using silica gel to store tea, if the particles of the desiccant are found to change from the original blue to translucent light red to white, it must be dried The agent is taken out and baked into blue in the sun or a slight fire, and then continue to use, it is very affordable.
