Basic chemical reactions of coffee beans 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.

Five flavors of Fine Coffee
The color, aroma and taste of sweet coffee are caused by some complex chemical changes that take place during the roasting process. Therefore, raw beans must go through appropriate chemical procedures 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 coffee is hot.

Processing methods of coffee beans with low caffeine
CO2 low-caffeine treatment and other low-caffeine treatments are described as follows: at present, there are three ways to remove caffeine from coffee beans: 1. Water treatment can remove 9496% of the caffeine. 2. Chemical extraction method, early use of chloroform (Chloroform) and benzene (Benzene) as solvents to extract caffeine, and later understand that these chemicals cause cancer, and then gradually become other low-hazard chemicals.

Basic knowledge of coffee what is the taste of coffee
The color, aroma and taste of coffee are caused by some complex chemical changes that take place during the baking process. Therefore, raw beans must go through appropriate chemical procedures to achieve the most balanced state of its essential ingredients in order to be regarded as the best baked beans. The aroma of coffee varies with the heat, so the baking time should be shortened as much as possible, and the heat can be controlled at the level of coffee beans.

How many chemicals are there in a cup of coffee
Coffee flavor chemistry has been studied for more than 200 years. Researchers have been committed to the separation and identification of coffee flavor substances. At present, more than 1000 coffee flavor substances have been reported. People can smell the aroma of coffee, because of the volatility of chemical molecules, the flavor of these chemical molecules is combined to form the taste of coffee.

Caffeine: caffeine is the most eye-catching of all the ingredients in coffee. It is a kind of phytoxanthin (animal muscle component). It has the same properties as theobromine contained in cocoa, green tea contains the same theophylline, and the percentage of reduction after baking is very small. Caffeine has a very wide range of effects. will affect the human brain, heart, blood vessels, gastrointestinal, muscle and kidney and other parts, the right amount of caffeine

Scientists study how the bitterness of coffee helps to improve the taste of coffee
Although this is done to coordinate the bitterness of the drink, the reason why coffee makes us frown has been wondered by scientists for decades. Now, researchers have narrowed down the typical scope of this exploration by identifying two compounds associated with coffee, whether gentle breakfast coffee or Italian espresso bitterness. An annual meeting of the American Chemical Society was announced in Boston.

Coffee rust is mainly harmful to leaves and sometimes to young fruits and twigs. After the leaves were infected, many light yellow spots appeared at first and enlarged in the form of water stains, followed by orange-yellow powdery spores on the back of the leaves, and there was a light green halo around the disease spots, which gradually expanded or connected in the later stage.
