[caffeine]

Caffeine is the most striking of all the ingredients in coffee. It belongs to a kind of plant butter (animal muscle composition) and has the same properties as theobromine in cocoa and theophylline in green tea with a very small percentage reduction after baking. Caffeine has a wide range of effects, affecting the brain, heart, blood vessels, gastrointestinal tract, muscles, activating myocardial function, dilating blood vessels, enhancing blood circulation, and improving metabolic function. Caffeine can also reduce muscle fatigue and promote digestive juice secretion.

[fat]

The fat in coffee plays a very important role in flavor. After analysis, it is found that there are many kinds of fat in coffee, the most important of which are acidic fat and volatile fat.

[tannic acid]

After extraction, tannic acid will turn into a yellowish powder, which can easily blend into water, and after boiling, it will decompose and produce pyrosylic acid, which will make the coffee taste worse, and if it is brewed and left for several hours, the color of the coffee will become thicker than when it was just brewed, and it is also less tasty, so there is the saying that "it is best to drink it as soon as possible."

[minerals]

There are lime, iron, sulfur, sodium carbonate, phosphorus, chlorine, silicon and so on, because the proportion is very small, affecting the flavor of coffee is not great, combined to bring only a little astringency.

[sugar]

Raw coffee beans contain about 8% sugar. After roasting, most of the sugars are converted to caramel, which browns the coffee and combines with tannins to produce sweetness.

[crude fiber]

The fiber of raw beans will be carbonized after baking, and the caramel of carbon and sugar combine with each other to form the hue of coffee, but the fiber turned into powder will have a considerable impact on the flavor of coffee, so we do not encourage the purchase of coffee powder.
