Some complex chemical changes in the roasting of coffee
The color, aroma and taste of coffee are caused by some complex chemical changes that take place during the baking process. Generally speaking, we use strong alcohol to show the round, mellow and strong taste of coffee. So raw coffee beans must go through a proper chemical process to achieve the most balanced state of its essential ingredients in order to be regarded as the best baked beans. The aroma of coffee will follow the heat.

The color, aroma and taste of coffee are caused by some complex chemical changes that take place during the baking process. So raw coffee beans must go through a proper chemical process to achieve the most balanced state of its essential ingredients in order to be regarded as the best baked beans. The aroma of coffee will change with the heat, so the baking time should be shortened as much as possible, and the heat should be controlled within the range of heat.

The chemical structure of coffee and its changes show the characteristics and processing of coffee.
Coffee has long been recognized by the public, and chemistry is also a compulsory course in education in our country. However, we must not know much about the chemical structure of coffee and its changes. Readers may not be very interested in the content that is too theoretical. Now we will use more artistic pictures and language to show you the characteristics and processing of coffee. Coffee can spread all over the world in a hundred years.

Coffee beans wither, too?
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

The process of roasting coffee
1 is the state of raw coffee beans, 2 is that coffee beans are heated at the furnace temperature 3. As the temperature rises, the free water in coffee beans begins to evaporate, and the beans begin to change from green to yellow. At this stage, beans still have obvious grass flavor. 4 coffee beans are further dehydrated, from light yellow to color similar to longan. At this stage, the free water in coffee beans is further removed, and coffee beans gradually expand 5.
