Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
Various methods can be used for decaffeination of coffee. These methods take place prior to roasting and may use organic solvents such as dichloromethane or ethyl acetate, supercritical CO 2, or water to extract caffeine from the beans, while leaving flavour precursors in as close to their original state as possible.
In the case of decaffeinated coffee, eliminating caffeine can cause a sharp decline in the natural taste of the coffee bean.During the process of decaffeination, the largest coffee producers in the world use a variety of ways to remove caffeine from coffee, often by means of chemical manipulation and the use of potentially harmful chemical components, such as methylene chloride or ethyl acetate.
During the manufacturing process, decaf producers add solvents like methylene chloride or ethyl acetate (an alternative derived from sugarcane) to bind to the caffeine in green coffee beans. This ...
The FDA has one regulation allowing for the use of methylene chloride as a solvent to decaffeinate coffee, stipulating that “the residues of methylene chloride must not exceed 10 parts per ...
