What is Green Coffee

Green coffee refers to coffee beans that have not been roasted

Usually, the beans are picked, processed wet, dried and then milled. They are not roasted because that process is usually left to the end consumer. Most of the coffee beans traded in the international markets are green coffee beans, meaning unroasted beans. The coffee plant is a small tree which produces fruits, called cherries. As part of the harvesting and production process, the cherries are dried in the sun for several weeks until their flesh splits, releasing the bean. This bean is what is known as green coffee.

Green coffee

Green coffee bean contains a natural compound called Chlorogenic Acid. When coffee beans are roasted in high temperature, the chlorogenic acid is mostly destroyed, thus giving rise to the release of the coffee’s aroma, flavor and brown color.


Chlorogenic acid is a polyphenolic compound (多酚化合物)

that is known to be a natural antioxidant that neutralizes free radicals in the body. Free radicals oxidize cells in the body to cause cell degeneration, slow down metabolism resulting in accelerated aging and weight gain.

Chlorogenic acid can slow down cell degeneration. It can also slow down the release of glucose into the bloodstream, thus regulating blood glucose level, helps burn fat, limits the storage of fat, and is used for weight control.

chlorogenic acid

Green coffee bean has the highest content of chlorogenic acid

among natural plant sources. Green coffee bean extract is generally consumed as a supplement, since drinking liquid coffee made from unroasted coffee beans would have a bitter unpleasant taste, and would not provide the desired dosage of chlorogenic acid.

Roasting process can destroy up to 70% of the chlorogenic acid

content in the coffee bean. So the potential health benefits from drinking regular coffee (i.e. coffee brewed from roasted coffee bean) would be significantly less than taking a green coffee chlorogenic acid supplement.


According to a published article by Harvard University in the September 2011 issue of Nutrition Journal, a person needs to drink at least five cups of black coffee a day to gain the health benefits of coffee. Most people seldom drink this much of coffee in a day, and caffeine can increase health risks and even cause poisoning. Raw coffee beans are also difficult to digest and consuming it direct may cause indigestion.


By extracting the active ingredients using patented extraction technologies,

we can achieve high concentration of chlorogenic acid for easy consumption, while gaining optimal effectiveness without the extra burden on health.
