Description

technical field

[0001] The invention relates to a method for storing green tea green tea leaves and a tea making method. Background technique

[0002] At present, the storage of famous and high-quality green tea all adopts the mode of finished tea to preserve, or normal temperature storage, or refrigerated (0-10 ℃) preservation. The method is relatively simple, but it is impossible to drink new tea from time to time, because tea is a seasonal agricultural product. Storage of fresh leaves is also impractical. Fresh leaves are an isolated biological living substance, and long-term storage is almost impossible. The green leaves have inhibited the activity of biological enzymes, so they can meet the storage requirements. Oolong tea has been stored in the Taiwan area of ​​my country and sold in the form of frozen tea [Zhou Wentang, Tea, 1997, 25 (1), -48]. Masuzawa Takeo of Japan [Tea Industry Research Report, 1997, 85 (Supplement), -68~69] has conducted research on the froze...
