Abstract

The invention discloses a green tea processing method which includes the steps: picking fresh one-bud four-leaf tea leaves, spreading the tea leaves in a light-resistant environment with the oxygen content of 6-7% and the temperature of 8-11 DEG C, uniformly spraying enzyme preparations, cooling green leaves in an indoor environment with the temperature of 28-30 DEG C and the relative humidity of82-85%, sequentially performing steaming, double microwave heating and double fried water removing, and rolling the tea leaves to reach the water content of 35-39wt% to obtain rolled leaves; placing the rolled leaves at the temperature of -45 DEG C to -25 DEG C for 3-5 hours, placing the rolled leaves at the temperature of -20 DEG C to -10 DEG C for 3-5 hours, placing the rolled leaves at the temperature of -5 DEG C to -3 DEG C for 3-5 hours and placing the rolled leaves at room temperature for 5-10 hours to obtain freeze-dried leaves; drying the freeze-dried leaves in a dryer and roasting thefreeze-dried leaves in a wok to obtain green tea. The green tea processing method is simple in process, and the obtained green tea is strong and lasting in fragrance, strong, tasty and refreshing intaste and high in quality.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a green tea processing method. Background technique [0002] Tea has multiple health functions and is one of the most popular health beverages among consumers. Green tea, also known as non-fermented tea, refers to a drink made from the new leaves or buds of tea trees without fermentation, through processes such as greening, shaping, and drying. It retains more natural substances in fresh leaves and has anti-inflammatory properties It has special effects such as aging, anti-cancer, anti-cancer, sterilization, anti-inflammatory, lipid-lowering and weight-loss. It is one of the six major teas in my country, and it is also the tea category with the largest production and sales and the most advanced processing technology in China. However, the existing green tea processing methods fail to fully transform the beneficial ingredients in green tea, and the green tea produced has th...
