Tea cold storage low temperature cold storage fresh tea characteristics: tea cold storage low temperature fresh tea technology is the most advanced, the best effect, the establishment of a dedicated tea cold storage is the most effective way to solve the large-volume famous green tea storage and preservation. Low temperature refrigerating can keep the tea fresh under low temperature conditions, and protect from light and dehumidification, can greatly extend the shelf life of tea, build a small tea cold storage, can maintain the color, aroma and taste of tea, improve the economic value of tea, and achieve no refrigeration. The history of spring tea is unattended.
Characteristics and time of tea storage at room temperature: How to maintain the freshness of the tea, avoiding the storage of the tea under natural room temperature conditions, and the change of the active ingredient contained therein is faster.
Even under the conditions of moisture-proof and heat-insulated storage, the color, aroma and taste of tea in stock for 2-3 months have obvious changes, which are manifested by the decrease of fresh refreshing degree of tea and browning of brown color. In the case of green tea, it is obvious that improper handling during storage causes deterioration and odor. As the storage period is extended, the new tea becomes Chencha. In addition to some of the “healing better†steamed tea leaves, most teas require preservation. The fresh phase and the green color are the sensory quality characteristics of the famous green tea. Due to the high quality of famous tea in China, most of it is produced in the spring tea season (March-May). Under natural room temperature conditions, after high temperature and humid summer, it is a famous tea product with good storage conditions. On National Day, On the New Year's Day and the Spring Festival, the phenomenon of ageing is different. The characteristics of the famous tea season production and annual supply require a storage period of 6-12 months or even longer. Pay attention to the following points when using tea cold storage for fresh-keeping tea: Under the automatic control state, fresh tea can be optimally refrigerated after entering the warehouse.
If the tea with excellent quality is kept fresh, the temperature in the cold storage is preferably 0-2 °C. In the process of refrigerating, the famous green tea has a large difference in humidity between the inside and outside of the library. When taking tea from the library, the tea bag should be removed from the warehouse first, and the bag can be opened when the tea in the bag is gradually warmed to near room temperature. If the tea bag is opened immediately after the storage, the water vapor in the air will be liquefied into small water drops and the tea will be dampened and the tea will be aged. Before the tea is stored, especially before the first use of the new cold storage, or when the relative humidity in the middle storage is more than 65%, the ventilation and dehumidification should be carried out in time. After long-term use of the cold storage, there will be odor in the warehouse, which is unfavorable to the quality of the tea. It should be ventilated in time. It is generally required to clean the warehouse in 2 to 3 years to keep the interior clean and fresh.
