The basic chemical reactions that take place 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.

Coffee Health Research shows that Coffee can affect DNA in muscle
You might think that no matter what you do, your genetic DNA will not be affected, but in a sense, this idea is wrong. In March, in the journal Cell Metabolism, published by Cell Press, researchers reported that when men and women who did not exercise for a few minutes when they were in good health, their DNA levels increased.

Scientists have confirmed that coffee with sugar is not coffee.
Even if black coffee is romantic, not everyone can stand the taste. It still needs sugar. Why is it that sweetened coffee is not so difficult to taste? Scientists have found that the chemical structure of coffee has changed after adding sugar. Many people must be dismissive of this problem: of course, it is the sweetness of sugar that suppresses the bitterness, which needs to be studied. However, York, England

Bilingual coffee counseling: exercise and caffeine can change your DNA
Swedish researchers recently found that when men and women who are not physically active change their DNA instantly after a few minutes of exercise, when they are in good health. More surprisingly, the study suggests that caffeine in the coffee we drink in the morning may affect DNA in muscles in the same way. The study was published in the March issue of "details."

Roasting is the last and most important step in the processing of coffee beans after being picked. Raw coffee beans cannot be directly used as drinking coffee. All coffee beans must be roasted before grinding and brewing. Unbaked coffee is often called raw coffee, which has a shelf life of up to one year compared with roasted coffee.

Savor the bitterness 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 to deal with coffee beans to become decaf
In this century, scientists have developed three methods to extract and remove caffeine from coffee beans: (1) Chemical method dissolves caffeine in beans with chemical solvents, which can selectively dissolve substances, so it will not remove all the substances in coffee beans, and can retain the best original taste of beans. Using chemical methods, it is inevitable in coffee beans.
