Elisa Hofmeister Kokesh Hour 3 AP Chemistry 5-29-12 The Chemistry of Coffee Green Coffee- Before coffee is roasted‚ it is referred to as “green coffee”. The green coffee is primarily made up of caffeine‚ lipids‚ carbohydrates‚ proteins (amino acids)‚ and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase‚ and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee
