The method for preparing a tea beverage with slimming and skin-beautifying effects as described in any one of claims 1 to 3, characterized in that, Includes the following steps: (a) Add tea to water for the first water bath ultrasonic extraction and filtration. Place the residue in water for the second water bath ultrasonic extraction and filtration. Combine and concentrate the two filtrates to obtain the first concentrate. (b) Sterilize cucumbers, slice them, and sun-dry them until the moisture content is 18% to 25%. Then, juice and filter them to obtain cucumber juice. Add flavor protease and ethanol solution to the cucumber juice for enzymatic hydrolysis and enzyme inactivation. Filter the juice sequentially using 0.45 μm and 0.1 μm microporous membranes and collect the filtrate. Add polyethylene glycol and β-cyclodextrin mixture to the filtrate and stir at 50 to 60 °C for 1 to 3 hours. Then stir at room temperature for 2 to 4 hours. Filter the mixture using a 0.45 μm microporous membrane and dry it to obtain a pre-powder of polyethylene glycol and β-cyclodextrin. (c) Loquat flowers were added to water for the first water bath ultrasonic extraction and filtration. The residue was then placed in water for the second water bath ultrasonic extraction and filtration. The two filtrates were combined to obtain loquat flower extract. (d) Add wild Termitomyces albuminosus to water for the first water bath ultrasonic extraction and filtration. Place the filter residue in water for the second water bath ultrasonic extraction and filtration. Combine the two filtrates to obtain Termitomyces albuminosus extract. (e) Prepare a water-soluble mogroside syrup by preparing mogroside syrup, then mix the water-soluble mogroside syrup, the first concentrated liquid, the pre-powder of polyethylene glycol and β-cyclodextrin, the loquat flower extract, the termite mushroom extract and L-cysteine ​​to obtain a mixture, then add a diluent to the mixture and stir thoroughly to obtain the tea beverage with slimming and skin-beautifying effects.
