green tea, one of the main teas in China, refers to a drink made from the new leaves or buds of tea trees without fermentation, and after the processes of deactivation, shaping and drying. The color of its finished products and the brewed tea soup preserve the green style of fresh tea more. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and can also reduce nicotine damage to smokers.

Generally, there are the following methods to preserve green tea at home:

1. Pot storage of tea. This method has existed since ancient times. Ming Feng Mengzhen < Random record of Quick Snow Hall > As the saying goes, "If the bottom of a large urn of solid tea is placed in a pot, it will not turn yellow in summer, so that its gas will not leak out." The water content of tea leaves should not exceed 6%. It can be dehumidified with quicklime. The specific operation method is the same as that of lime block preservation.

2. The method of canning. The container is made of metal cans, boxes, cans, boxes, iron or aluminum or paper or other foods. Convenient access.

3. Tea storage in plastic bags. Choose high-density, high-pressure, thick, strong and odorless food packaging bags. Tea can be wrapped in soft clean paper in advance, then placed in food bags and sealed.

4. Tea storage in thermos bottles. You can use discarded thermos bottles with poor heat preservation, fill them with dry green tea, and cover the cork. Seal with wax.

5. Refrigerator preservation method. Green tea is packed in high-density, high-pressure, thick, strong and odorless food packaging bags, and then placed in the freezer or freezer of the refrigerator. This method has a long storage time and good effect, but the bag mouth must be sealed tightly, otherwise it will regain moisture or smell, which will damage the quality of green tea.

if the green tea is stored in the refrigerator, it may be because the bag mouth is not sealed properly, resulting in moisture regain or odor, which will naturally affect the taste of green tea.
