Analysis of the steps in coffee roasting the roasting degree of coffee and the roaster of coffee all affect the quality of beans.
Once the coffee seed is planted, no one can change its final quality. However, the color, aroma, bioactive components and health characteristics of coffee are related to the roasting process. During the roasting process, coffee is heated at 190-220 degrees for 7-20 minutes, which helps to bake out its aroma and good taste, and helps to form lactone, nicotinic acid and resistance.

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.

Do you believe the main reason why coffee is getting worse?
Deterioration refers to the change in which the properties of polymers are reduced and cannot be recovered. Due to the action of heat, light, ultraviolet light, oxygen, ozone and various chemicals, polymer materials will change their physical or chemical properties, such as discoloration, cracking, intensity reduction and so on. These external conditions can cause the breakage or cross-linking of the polymer main chain, resulting in structural changes and reduced properties. Baked coffee
