[0029] The preparation method of the above dark tea beverage is as follows: ferment after mixing the black tea water, Sanxian extract and probiotics, and then add a sweetener to prepare the dark tea beverage.
[0030] Specifically, the preparation method of the dark tea water is as follows: put 3-4 parts of black tea into 600-1000 parts of water, boil for 5-10 minutes, and cool down.
[0031] The preparation method of the Sanxian extract is as follows: add 160-250 parts of water to the mixture of 2-3 parts of burnt hawthorn, 4-5 parts of burnt malt, and 2.5-4 parts of Jiao Shenqu, and put it into ultrasonic cleaning Ultrasonic extraction in the machine, filtration, preferably suction filtration, to obtain the Sanxian extract.
[0032] The working conditions of the ultrasonic extraction are: ultrasonic for 35-45 minutes at a temperature of 50-60° C. and a power of 300-350 W.
[0033] Further, the preparation method of the Sanxian extract also includes the following steps: addi...
