is chinese tea acidic
In fact, after tea leaves are burned into ash and dissolved in water, the pH value of their solution is greater than 7, indicating alkalinity. This is because tea contains various minerals such as potassium, sodium, calcium and other metallic elements, which can be digested and hydrolyzed in the body to produce alkaline substances. Therefore, from the perspective of tea itself, tea is considered an alkaline food.
Is black tea alkaline or acidic
Black tea belongs to alkaline beverages. The differentiation of food acidity and alkalinity is mainly based on the types of inorganic salts in the food. Foods that contain a high amount of potassium ions, magnesium ions, sodium ions, and calcium ions are considered alkaline foods. If it contains a high amount of sulfur and chlorine, it belongs to acidic food. Black tea is rich in inorganic salts such as potassium, magnesium, phosphorus, and calcium, making it an alkaline food.
How acidic is black tea compared to coffee
The acidity of coffee mainly comes from its components, chlorogenic acid and organic acids, which make coffee exhibit high acidity in taste. Chlorogenic acid accounts for about 5% -8% in Arabica coffee beans, while it accounts for about 7% -11% in Canefra coffee beans. These components are one of the main sources of coffee acidity. In addition, coffee also contains small amounts of citric acid, malic acid, phosphoric acid, etc. Although the amount is very low, about 2%, these acids are also an important source of many coffee fruit aromas, thereby increasing the perception of acidity in coffee.
In contrast, black tea has relatively low acidity. During the production process of black tea, some acidic components in the tea may decrease due to fermentation and oxidation, resulting in a less pronounced perception of acidity in black tea compared to coffee. In addition, when brewing black tea, the control of water temperature and the length of brewing time can also affect the release of acidic substances in black tea, further affecting its perception of acidity.
Therefore, although both black tea and coffee contain certain acidic components, overall, the acidity of coffee is higher than that of black tea, especially in tea drinks made from unfermented or lightly fermented tea leaves, where this difference is more pronounced.
