At the beginning of the 19th century, the composition of tea gradually became clear. After modern scientific separation and identification, tea contains more than 450 organic chemical components and more than 40 inorganic mineral elements.
Organic chemical components mainly include: tea polyphenols, plant alkaloids, proteins, amino acids, vitamins, pectin, organic acids, lipopolysaccharides, carbohydrates, enzymes, pigments, etc. The content of organic chemical components in Tieguanyin, such as tea polyphenols, catechins, and various amino acids, is significantly higher than other teas. Inorganic mineral elements mainly include potassium, calcium, magnesium, cobalt, iron, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine, selenium, etc. The inorganic mineral elements contained in Tieguanyin, such as manganese, iron, fluorine, potassium, and sodium, are higher than other teas.
Commonly known as tea tannins, it is a unique ingredient of tea with bitter, astringent and astringent properties. It can be combined with caffeine in tea soup to relax the physiological effects of caffeine on the human body. It has the functions of anti-oxidation, anti-sudden mutation, anti-tumor, lowering blood cholesterol and low-density ester protein content, inhibiting blood pressure rise, inhibiting platelet aggregation, antibacterial, and anti-product allergy.
It has a bitter taste and is an important ingredient in the taste of tea soup. In black tea tea soup, it combines with polyphenols to form a compound; the tea soup forms an emulsification phenomenon when it is cold. The unique catechins and their oxidative condensates in tea can slow down and continue the excitatory effect of caffeine. Therefore, drinking tea can help people who drive long distances to keep their minds clear and have more endurance.
Tea is rich in 11 kinds of minerals including potassium, calcium, magnesium and manganese. Tea soup contains more cations and less anions, which is an alkaline food. It can help body fluids maintain alkaline and keep healthy.
① Potassium: promote the elimination of blood sodium. High blood sodium content is one of the causes of high blood pressure. Drinking more tea can prevent high blood pressure.
②Fluorine: It has the effect of preventing tooth decay.
③Manganese: It has anti-oxidation and anti-aging effects, enhances immune function, and helps calcium utilization. Because it is insoluble in hot water, it can be ground into tea powder for consumption.
B vitamins and vitamin C are water-soluble and can be obtained from drinking tea.
5. Pyrroloquinoline quinone
The pyrroloquinoline quinone component in tea has the effects of delaying aging and prolonging life.
6. Other functional components
①Flavone alcohols have the effect of enhancing the walls of capillaries to eliminate bad breath.
②Saponins have anti-cancer and anti-inflammatory effects.
③Aminobutyric acid is produced by forcing tea leaves to undergo anaerobic respiration during the tea making process. It is said that Jiayelong tea can prevent high blood pressure.
