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.

(1) Caramelization: the sugar in coffee beans is caramelized at about 170-200 ℃, which is exactly the melting point of sucrose (185 ℃) and the temperature of the explosion stage when coffee beans are roasted. The product of caramelization is divided into two parts: 1. The dehydration product of sugar is caramel or sauce 2. The pyrolysis products are mainly volatile aldehydes and ketones. In general, in the caramelization reaction
