AI Technical Summary

Problems solved by technology

[0009] In the prior art, health teas prepared from a single ginkgo tea or a combination of ginkgo leaves and tea leaves, or a combination of ginkgo leaves and other beneficial raw materials generally ignore the utilization effect of the active ingredients of ginkgo leaves, resulting in poor product effects. It is difficult to achieve the expected effect, which affects the awareness of consumers and is difficult to promote

The reason is that the cell wall and cell membrane of Ginkgo biloba are constantly lignified during the growth period, and the texture of Ginkgo biloba varies greatly due to different picking time. The main components of Ginkgo biloba are ginkgo ketone compounds, lactone compounds, Organic ingredients such as polyisoamyl alcohol and ginkgo polysaccharides, after being made into tea, simply soaked in boiling water, it is difficult to extract their fat-soluble active ingredients, which is the main reason for the unsatisfactory effect after drinking

The 2nd, existing processing technology is unreasonable, only is simple tea-making method, is difficult to reach the medical curative effect of ginkgo leaf, can not realize the medical value of existing ginkgo tea

[0010] As the middle-aged and elderly people's cardiovascular and cerebrovascular health problems are getting more and more attention, improving the medical and health care value of ginkgo biloba, combined with the excellent characteristics of white tea, should be able to better exert its efficacy and solve the above problems, especially more It is suitable for drinking in summer, and it will have a significant application effect, but there is no relevant report in the prior art
