[0019] ① Green tea beverage production
[0020] The green tea and water are mixed in a weight ratio of 1:100, and the active ingredients are extracted according to the process described in the technical scheme under the conditions of a pressure of 300MPa-500MPa and a pressure holding time of 10-15 minutes. The green tea is filtered from the mixture of green tea and water discharged from the pressure vessel (aseptic operation), and the filtrate is directly filled (aseptic operation).
[0021] This method can use various kinds of drinking water (except tap water) such as lake water, river water, spring water, and well water. It only needs to filter out impurities in the water without sterilization.
[0022] ② Tea polyphenol extraction
[0023] Mix green tea (any variety, any grade, or fresh leaves) with water in a weight ratio of 1:20. Under the conditions of a pressure of 300MPa-500MPa and a pressure holding time of 10-15 minutes, the effective ingredients are made according to the pro...
