Green Coffee Bean means un-roasted coffee that has higher nutritional value than roasted coffee whose nutrients have been partially destroyed during roasting. The main constituents of coffee include polyphenol compounds, polysaccharides and caffeoylquinic acid derivatives such as chlorogenic acid and cynarin. Skyherb’s green coffee bean extract GCBest is made from the unroasted beans of Coffea Arabica L., and results in a high level of chlorogenic acid and other caffeoylquinic acids. Besides its supreme anti-oxidant and fat accumulation suppressing properties, Skyherb’s green coffee bean product is water-soluble, which allows its easy addition in drinks.
