In-depth Analysis of Coffee Taste from Chemical Angle
It has been said that adding salt to coffee can neutralize bitterness, which sounds ridiculous, but it has been proved to be effective by science. In 1997, scientists tried to put salt into a bitter chemical solution and compared the bitterness of the solution. It was found that although the concentration of bitter elements in chemical solvents did not change, the chemical solution with salt did not taste so bitter.

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.
