As small as they appear, coffee beans are a composition of some natural compounds Arabica and Robusta coffee, you can find a more indepth analysis here.

and composition of the ether-soluble or fat constituents of the coffee-bean. This part of the work was first taken up because it seemed very probable that the staling of roasted coffee is due in part, at least, to oxidative changes of the unsaturated constitu- This review focuses on the chemical characteristics, biosynthesis, and distribution of CGA and related compounds in coffee. The influence of genetic, physiological and environmental factors as well as processing on the chemical composition of coffee beans is discussed. The impact of CGA composition of green coffee on cup quality is also approached. Data on coffee composition and mass spectrometry analysis of mixtures of coffee related carbohydrates, phenolic compounds and peptides Author links open overlay panel Ana S.P. Moreira a Fernando M. Nunes b Cristiana Simões b Elisabete Maciel a c Pedro Domingues a M. Rosário M. Domingues a Manuel A. Coimbra a Elemental Coffee Analysis. To guarantee stated quality and safety of a final coffee product and protect well-being and health of consumers, different parameters responsible for the wholesomeness of green beans, roasted beans, prepared coffee and its infusions have to be measured using suitable analytical methods. Coffee naturally contains a variety of compounds including caffeine, antioxidants and diterpenes. These contribute not only to the unique flavour but also to the well-researched physiological effects of coffee.
