Tea has the characteristics of moisture absorption and easy odor absorption. If the tea is not well kept, the new tea will soon deteriorate and lose its drinking value for several months. The following is a brief description of family safekeeping: 1. The tar absorption method of limestone uses moisture absorption of quicklime. , Absorb excess moisture in the tea leaves, so that the tea leaves remain fully dry, thus delaying aging. Lime is placed in a cloth bag, and the tea leaves are wrapped with kraft paper and placed around the altar. A pack of lime is added, and a packet of tea leaves is placed on it. Then the altar is closed. If lime is not chalked, it can be temporarily replaced. This method works best. 2. The Tie-Tang storage method will timely pack the fully dry tea leaves into the iron cover with a double cover, and try to load enough to reduce the listening air and maintain the quality of the tea. After installation, cover the double cover and seal it with tape. The iron can be covered with two plastic bags and the bag can be tightly closed. With this method, tea quality can also be maintained for a longer period of time. 3. The method of storing plastic bags is to put the tea into a plastic bag, squeeze out the air inside the bag, tie the bag mouth, and then put it into another plastic bag, tie the bag mouth, and finally put it into a dry, odorless, closed container in. 4. The hot water bottle storage method is to put the tea into a hot water bottle, stopper the stopper, seal it with white wax, and wrap it with tape. 5. The specific method of the refrigerator-freezer method is similar to the method of storing iron and plastic bags. The packaged tea is placed in the refrigerator and the low temperature is used to maintain the stability of the tea. It is an economical and effective method of storage, but it must be carefully packed to prevent contamination by odors.
