Baking can be divided into three stages: drying, high temperature decomposition and cooling.
Drying in the early stages of baking, raw beans begin to absorb heat and the internal water gradually evaporates. At this time, the color gradually changed from turquoise to yellow or light brown, the silver film began to fall off, and a faint smell of grass could be smelled. The main function of this stage is to remove moisture, which accounts for about half of the baking time. Because water is a good thermal conductor, it helps to bake the internal substance of coffee beans. So, although the eye

How does the coffee taste when it's deep roasted?
Deep roast coffee differs from other coffees in the mixing process of the basic tastes. Due to the intense thermal decomposition of coffee beans, most of the sugar in coffee is broken down. Loss of sweetness in taste. Due to the addition of carbolic compounds, sweetness is replaced by bitterness. Bitterness is often misunderstood. Bitterness in food is often regarded as something bad. However, in certain foods,

Basic chemical reactions that occur during coffee roasting
Many thermal and chemical reactions take place during baking: decarbonation, dehydration of quinic acid, fragmentation, isomerization, polymerization, and complex sugar reactions (caramelization). The main thermally reactive components are monosaccharides and sucrose, chlorogenic acid, displaced amino acids, and trigonelline amide. Both aravinone and calactose in polysaccharides are transferred, and basic sulfurization contains hydroxyamino acids.
