Why does chrysanthemum tea change from yellow to green?
Chrysanthemum is mainly composed of flavonoids, volatile oil, triterpenoids, organic acids and so on. At present, its medicinal components are mainly flavonoids, and its nutritional components are mainly concentrated in the analysis of basic nutrients, soluble sugar, amino acids, mineral elements and so on.
In recent years, many studies have found that flavonoids have good antioxidant properties, can help the human body eliminate free radicals, and have a variety of health effects such as antioxidant, anti-cancer, lowering cholesterol and inhibiting the rise of blood pressure.

In addition, the acidity and alkalinity of tea making water and metal ions in water will also affect the color of chrysanthemum tea.
Wuhan University found that if the water used to make tea is alkaline, chrysanthemum tea will be yellow. If the water is acidic, the tea will be reddish orange; If there are more iron ions and aluminum ions in the water, the color of chrysanthemum tea will also be different.
Therefore, chrysanthemum tea soaked in tap water tends to be yellow and orange, while tea soaked in distilled water is lighter.
Now tea friends should know why Huangju tea party is becoming more and more "green"! What's more, the chrysanthemums of Xuande Huangju are personally planted, planted, picked, baked and so on by the villagers of our base, which ensures that they are pure natural green organic products!
Drinking method of Huangju
1. It is recommended to use transparent glass cups (POTS). Put 1-2 chrysanthemums into each cup (pot), soak in 100 ℃ boiling water for 1-2 minutes, and the tea soup is bright yellow.
2. Add boiling water to the remaining one-third after each drink. After a while, you can continue to drink. You can brew it repeatedly for several times until the fragrance of Huangju fades.
3. When drinking by more than one person, 2-4 chrysanthemums can be put into the transparent glass pot at one time. The brewing method is the same as above.
4. Drinking 2-3 times a day for a long time can achieve the effect of health care.
Therefore, chrysanthemum tea will turn green after soaking for a long time, but it has no toxic and side effects, and has nothing to do with the quality of chrysanthemum tea.
But experts suggest that any tea should not be soaked for too long, such as overnight tea, which will breed bacteria and be harmful to health.
