What is tannic acid? One of the main chemical constituents of coffee beans

Tannin, one of the main chemical components of coffee beans, accounts for about 7% of the total chemical composition of coffee beans. After extraction, tannic acid will turn into a yellowish powder and easily dissolve in water. Once heated, it will decompose to produce pyrosylic acid, making the taste of coffee worse. Because of this, a cup of brewed coffee will lose its taste and taste if it is not drunk immediately.
