Is tea better frozen or refrigerated?

It is best to keep tea in cold storage, and the cold storage temperature is about 2- 10℃. Tea that is not often drunk can be frozen in the refrigerator.

Tea has a strong adsorption capacity. It's best to store it in the refrigerator with plastic bags or tin paper bags, and don't put it together with odorous items, so as to avoid the tea absorbing odor and affecting the taste. But that's the point. There are two prerequisites for whether tea is refrigerated or frozen. One depends on what kind of tea you store, and the other depends on whether you store it for a short time or a long time.

If you store green tea, yellow tea and fragrant oolong tea, you can put them in the refrigerator. If you store black tea, white tea, black tea, high-temperature baked oolong tea, scented tea and other tea leaves, it is not suitable to put them in the refrigerator, let alone refrigerate or freeze them. On the contrary, Pu 'er and black tea are also afraid of resurgence and deterioration. Different kinds of tea, different preservation methods, depending on the tea.

How to keep tea in cold storage?

1, tea placement. It is recommended to use special shelves for display.

2, cold storage temperature probe installation. It should be installed at the air inlet behind the air cooler and cannot be installed at will. If the probe is improperly installed and the air duct is blocked, the tea will deteriorate due to long-term exposure to high temperature.

3. Temperature setting. The recommended cold storage temperature of famous green tea is 58℃. If the weather is hot, the temperature difference between tea and air can be reduced by increasing the temperature of cold storage, and the running time of fresh-keeping equipment can be shortened, thus prolonging the service life of equipment and reducing energy consumption.

4. Tea leaves the warehouse. When the tea leaves are taken out of the cold storage, the tea bags should be removed from the warehouse first, and then the packaging bags should be opened when the tea bags gradually heat up and are close to room temperature. Because of the great difference in humidity in the cold storage, if the tea leaves are opened as soon as they are taken out, the water vapor in the air will contact with the tea leaves with low temperature, resulting in small water droplets, which will cause the tea leaves to get wet and accelerate the aging of the tea leaves.

5. Tea leaves should be packed orderly in the warehouse. The evaporator of the tea fresh-keeping warehouse adopts a cold fan to forcibly circulate the air in the warehouse to achieve the purpose of ventilation, cooling and dehumidification. Therefore, the orderly stacking of tea leaves is the premise of ensuring the air flow and circulation in the warehouse, making the temperature in the warehouse uniform and improving the storage quality of tea leaves.
