General knowledge of Fine Coffee reaction in the process of roasting coffee
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.

What are they? Many plants contain chlorogenic acid in addition to caffeine. Acids have this very similar structure in the Luyuan Group, and the composition of an ester usually includes caffeic acid and quinic acid as components. All chlorogenic acids belong to a larger class of phenolic acids. In nature, phenolic acids are usually used as defensive compounds by plants, or as a signaling mechanism between plants and soil microorganisms. they

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
