Problems solved by technology

[0006] It can be seen that in the prior art, for the processing of black tea, the traditional tea processing technology is changed, so that other substances or extracts can be added in the processing process, and then the nutritional elements inside the black tea are improved to achieve the purpose of providing black tea. The health care effect of pine needles has already been reflected, but for the combination of pine needles, shirt leaves, prickly pear leaves, persimmon leaves, fresh leaves of Duobei tea, corn silk, mulberry leaves, etc., and to control the processing parameters for these raw materials, Technical research on further improving the nutritional structure inside black tea and enhancing the health benefits of black tea does not yet exist

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to black tea and a preparation method thereof. Background technique [0002] Black tea has the functions of anti-oxidation, delaying aging, relaxing blood vessels, nourishing the stomach and protecting the stomach. However, black tea is warm, and it is not suitable for people with fire constitution. Drinking black tea for a long time will cause coldness, heart palpitations, and slow down the body's absorption rate of calcium elements, which will affect the health of the body, and then make the drinker drink black tea up to Not for the purpose of health care. [0003] For this reason, many researchers have carried out various researches and discussions, compounding black tea and other raw materials to overcome the defects of black tea itself, and at the same time enhance the health care function of black tea, improve the nutritional structure of black tea, and effectively inc...
