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

Chemistry Notes Cracking: * 2 types of Cracking; Catalytic cracking and Steam/thermal cracking. * Catalytic cracking‚ using a catalyst called Zeolite (Aluminosilicate)‚ 500 degrees C‚ in the absence of air and at pressures just above atmospheric * Thermal cracking is done without a catalyst; steam is passed through very hot metal tubes at 700-1000 degrees C at just above atmospheric pressure. * This is used to break down longer chains of unsalable hydrocarbons into smaller salable
