Composition analysis

Caffeine: caffeine is the most eye-catching of all the ingredients in coffee. Its effect is extremely extensive, and it will affect the brain, heart, blood vessels, gastrointestinal tract, muscle, kidney and other parts of the human body. An appropriate amount of caffeine stimulates the cerebral cortex, promotes sensation, judgment, memory, and emotional activity, makes the myocardial function more active, dilates blood vessels, enhances blood circulation, and improves metabolic function. Caffeine can also reduce muscle fatigue and promote digestive juice secretion. In addition, because it also promotes kidney function and helps the body expel sodium ions from the body, caffeine does not accumulate in the body like other narcotic and excitatory substances and will be excreted in about two hours.

Tannic acid: the refined tannic acid will turn into a yellowish powder, which can easily blend into the water. Once boiled, it will decompose and produce pyrosylic acid, making the coffee taste worse.

Fat: the fat contained in coffee plays a very important role in the smell of coffee. After analysis, it is found that there are many kinds of fats in coffee, the most important of which are acidic fat and volatile fat. Acidic fat means that fat contains acid, and its strength varies with different types of coffee. Volatile fat is the main source of coffee aroma. It is a very complex and delicate thing that emits 40 kinds of aromatic substances.

Sugar: coffee beans contain about 8% sugar. After baking, most of the sugar will be converted to caramel, bringing a unique brown to the coffee.

Extract: can be divided into several kinds, accounting for nearly 1/3 of baked beans, light is still not known to cause what effect of the substance.

Minerals: there are lime, iron, sulfur, sodium carbonate, chlorine and so on, but because the proportion is not high, it does not affect the flavor of coffee, which will only bring a little astringency.

Crude fiber: the fiber of raw beans will be carbonized after baking. The caramelization of carbon and sugar combine to form the hue of coffee, but the fiber turned into powder will have a considerable impact on the flavor of coffee.
