Raw coffee beans contain sour ingredients such as citric acid, malic acid, quinic acid and phosphoric acid, but these are not the main sources of sour taste when drinking coffee. The acid produced during baking is the main source of sour taste. Raw beans produce a series of chemical reactions during baking to form new acids. The most important thing is that chlorogenic acid is decomposed to form quinic acid and oligosaccharides.

Usually coffee people describe coffee flavor refers to Acidity (acidity), is to describe a lively, bright, fresh, refreshing feeling. Usually when the taste of coffee is identified
2014-10-08 Coffee knowledge caffeic acid coffee trainingAcid acid is a chemical substance characterized by its sour taste. Acid is called acid in English and means sour in Latin. Chemically, the PH value of acid aqueous solution is less than 7, and the smaller the value is, the greater the acidity is. Many foods contain acidic compounds. Common foods include lemon, vinegar, yogurt or coffee. Coffee alone contains hundreds of acidic compounds, and then we

However, after roasting "fragrance" correctly, raw beans will emit the strongest aroma in the world. Grab a handful of coffee raw beans smell, there is always a pungent smell, very different from the impression of the charming smell of coffee. However, when raw beans are roasted correctly, they will be fragrant.

So the first question is whether there should be acid in coffee and what is the charming acid in coffee. When we talk about this problem, we have to compare the difference between Arabica coffee and Robusta coffee. Arabica coffee is superior to Robusta coffee in that the former has the complexity of taste. There are.

The main components of the thermal reaction are monosaccharides and sucrose, chlorogenic acid, free amino acids, and fenugreek amide. Both aravinose and calactose in the polysaccharides are transferred, and the basic vulcanization contains hydroxylated amino acid.
