Stir frying refers to the process of making tea by using the method of low fire to wither the tea in the pot. Through manual rolling, the water in the tea evaporates rapidly, blocking the process of tea fermentation, and keeping the essence of tea juice completely. Stir frying green tea is a major leap in the history of tea making.

   Roasting green is a turning point process that serves as a bridge between the previous and the next, quickly stopping a series of enzymatic oxidation processes and consolidating the formed quality characteristics. Starting is to continue losing some moisture, which facilitates the operation of shaping stages such as kneading and drying. The frying process also has a certain impact on quality.

  During the process of frying green tea, the temperature of the leaves increases, and the enzymatic activity rapidly increases. Within the optimal temperature range of 20-45 degrees Celsius for enzyme activity, the enzyme activity doubles for every 10 degrees Celsius increase in temperature. Some data suggests that the optimal temperature for polyphenol oxidase is 52 degrees Celsius. When the temperature rises to 70 degrees Celsius, the enzyme becomes inactive and denatured, and around 85 degrees Celsius, the enzyme solidifies and breaks down. In order to prevent the tea green from rapidly turning red during frying green tea, the leaf temperature should be raised to above 70 degrees Celsius in the shortest possible time. Therefore, frying green tea should have a certain high temperature. If you see the bottom of the pot or the frying machine turning white during the day and red at night, you can add the leaves.
