The downside of coffee is drinking too much coffee will lead to the loss of calcium. Let’s take a look at the coffee-related knowledge!

What Is The Main Ingredient Of Coffee?

Coffee is a beverage made from roasted coffee beans. It’s the main drink popular in the world with Keke and tea. The coffee tree is an evergreen small tree of the genus Rubiaceae. The coffee drink daily is made with coffee beans and various cooking utensils.

Coffee beans are the nuts inside the coffee tree fruit. Bake it in an appropriate way. The taste of a standard cup of coffee should not be bitter. A qualified barista will perform every step seriously of the way while making coffee.

Finally, the coffee presented to the guests will show different degrees of sweetness, acidity, alcohol thickness, or cleanness.



It’s the most widely known of all coffee ingredients. It belongs to the plant yellow matter (animal muscle component). Nature is the same as the theophylline contained in Koko and green tea. The percentage reduction after baking is extremely small.

The role of caffeine is extremely broad. It will affect the human brain, heart, blood vessels, gastrointestinal, muscle, and kidney. The right amount of caffeine will irritate the cerebral cortex. Promote sensory judgment, memory, and emotional activities. Make the myocardium function more active. Vasodilatation blood circulation is enhanced. And improve metabolism.

Caffeine also reduces muscle fatigue. Promote the secretion of digestive juice. In addition, it also promotes kidney function to help the body excrete excess sodium ions (chemical components that hinder the metabolism of water molecules).

So under the diuretic effect, caffeine does not accumulate in the body like other narcotic, excitatory substances (narcotics, paint solvents, stimulants, etc.). About two hours or so. It will be excreted, but too much intake can cause caffeine poisoning.

There is a particularly strong bitterness. The biggest feature of coffee flavor – bitterness caused by caffeine.


After refining, the tannin will turn into a pale yellow powder. It’s easy to integrate into water. When boiled, it will decompose and produce pyroantimonic acid. Make coffee taste worse. And if you brew it for a few hours, the color of the coffee will become thicker than when it’s soaked. Therefore, finish the coffee in a short time.


The fat contained in a coffee is a very important role in the flavor. The analysis found that the fat contained in coffee is divided into many types. The most important of these are acidic fats and volatile fats.

Acidic fat refers to the acidity of fat, which varies with the type of coffee. Volatile fat is the main source of coffee aroma. The fat contained in the roasted coffee beans comes into contact with the air, chemical changes will occur and the taste will be worse.


It’s the main source of coffee’s calories. The proportion is not high. The protein of coffee is not dissolved when brewing coffee so the intake is limited.


Coffee green beans contain about 8% sugar. Most of the sugar is converted to caramel after baking and make the coffee brown and combined with tannic acid to produce sweetness.


The fiber of raw beans is charred after baking. This caramelization of carbonaceous and sugar are combined with each other and form the color tone of the coffee. However, the fiber that is turned into a powder will have a considerable effect on the flavor of the coffee.

Therefore, we do not encourage the purchase of powdered coffee beans. It’s impossible to taste the flavor of coffee because of the position.


There are lime, iron, sulfur, sodium carbonate, phosphorus, chlorine, antimony, etc. Because the proportion is very small, it will not affect the flavor of the coffee. The combination only brings a little bit of bitter.


The aroma is the life of coffee quality. It’s also the most representative of the coffee production process and baking technology, the climate, elevation, variety, refining treatment, harvest, storage, and the baking technology of the consumer country.

It’s the condition of the flavor of the coffee beans. The aroma of the coffee is analyzed by chromatography gas. It’s proved by acid, alcohol, acetaldehyde, ketone, ester, sulfur compound, phenol, a nitrogen compound, etc. Nearly hundreds of volatile components are compounded.

Generally speaking, fat, protein, and sugar are important sources of aroma. The lipid component is in harmony with the acidity of the coffee and forms a smooth taste.

Therefore, the disappearance of the fragrance means that the quality is deteriorated. The relationship between aroma and quality is extremely close.
