A few days before Napoleon died on St. Helena Island in 1821, his attendant Marshal Bertrand wrote about Napoleon begging: "he asked for twenty times in the morning and asked me if I could give him some more coffee." "No, my lord, the doctor ordered you to drink only one spoonful of coffee. It's not time yet. You have a bad stomach. Drinking early will only make you vomit early. "he threw up nine times this morning.

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.

What's the aroma of coffee? Caramelization and Mena reaction during coffee roasting
Boutique coffee beans must be excellent varieties, such as the original bourbon species, mocha species and Tippica species. The coffee beans produced by these trees have unique aroma and flavor, which is far from that of other tree species, but the relative yield is low. in recent years, in order to pursue the ability of disease and insect resistance and increase the yield, there have been many improved tree species, such as the massive promotion of high-yield rurial11 species in Kenya.

The basic chemical reaction of coffee knowledge during coffee roasting.
Many thermal and chemical reactions take place during baking: decarbonation, dehydration of quinic acid, subdivision, isomerization, polymerization, and complex sugar reactions (caramelization). The main components of the thermal reaction are monosaccharides and sucrose, chlorogenic acid, free amino acids, and fenugreek amide. Both aravinose and calactose in the polysaccharides are transferred, and the basic vulcanization process includes hydroxylamine.

(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.

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
