For China people, drinking tea for health preservation is a tradition that has been passed down for thousands of years. There are many forms of tea in China, which can be divided into six categories according to different processing techniques: black tea, green tea, yellow tea, black tea, white tea and green tea. So what are the functions of tea? Please come with me to find out.
Flavonoids in white tea processing
Flavonoids and their oxidation products have a certain influence on the color and taste of white tea soup, and have a great influence on the antioxidant capacity of white tea. Six kinds of tea are all made from the same raw materials, and the content of flavonoids in them is decreasing in turn: white tea, green tea, yellow tea and black tea. Obviously, the flavonoid content of the three types of tea with withering technology is higher than that of the three types of tea with fixing technology, which is just the opposite to the change direction of tea polyphenols content. The flavonoid content of white tea is the highest, which is 17.2 times of that of fresh leaves, which may be the result of hydrolysis of flavonoid glycosides during long-term withering.
The content of flavonoids in Fuding white tea is as high as 2.025%, which is the highest among all teas. Flavonoids are natural antioxidants, which have strong antioxidant effect and can effectively neutralize active free radicals produced by ultraviolet rays and environmental pollution. The efficacy and function of a cup of Fuding white tea is equal to 12 cup of orange juice.
Flavonoids in the aging process of white tea
With the passage of time, the content of flavonoids in white tea increased year by year.
The magical effect of flavonoids
Flavonoids are powerful antioxidants.
Flavonoids have many functions. It is a strong antioxidant, which can effectively remove oxygen free radicals in the body. For example, anthocyanins can inhibit the overflow of oily peroxides at various stages, and its effect is more than ten times that of vitamin E. This antioxidant effect can prevent cell degeneration and aging, and also prevent the occurrence of cancer. The content of flavonoids with antioxidant activity in white tea is 14.2 ~ 2 1.4 times that of other teas. Therefore, white tea and its extract can be used as antioxidants to provide anti-aging effects. The antioxidant effect of white tea is even stronger than common antioxidants such as wort, Morinda citrifolia juice and fermented papaya.
Flavonoids can improve blood circulation.
Flavonoids can improve blood circulation and lower cholesterol. Flavonoids in Xiangtianguo also contain a PAF anticoagulant factor, which greatly reduces the incidence of cardiovascular and cerebrovascular diseases and can also improve the symptoms of cardiovascular and cerebrovascular diseases. In animal experiments, flavonoids called anthocyanins have been proved to reduce blood sugar by 26% and triglyceride by 39%. This hypoglycemic effect is amazing, but more importantly, it has a good effect on stabilizing collagen, so it has a good effect on retinopathy and capillary embrittlement caused by diabetes.
Flavonoids can promote wound healing and relieve pain.
Flavonoids can inhibit the exudation of inflammatory biological enzymes, promote wound healing and relieve pain. Quercetin can be used for various allergic diseases because of its strong antihistamine effect.
