Why do coffee beans turn brown after roasting? Why is there an aroma?
Coffee beans are light green and turn brown when roasted. This baking characteristic brown mainly comes from the brown pigment produced by oligosaccharins, amino acids and chlorogenic acids. The so-called brown pigment does not refer to a color or ingredient, but a general term for the many ingredients that make coffee different colors. Raw beans gradually change color during baking because of the total amount of brown pigment

The heat of shallow roasting is mild, because the sour aroma of flowers and fruits is most preserved by fermentation, so it is easy to smell the sour aroma of coffee. If the baking continues, that is, from the end of the first explosion to the middle baking before the second explosion, or even the medium and deep baking from the first explosion to the second explosion, most of the sour aroma of the fermentation catalysis has been broken up, instead of the taste spectrum of the sugar browning reaction (Sugar Browning) and Mena reaction.
