Why is DCM used for decaffeination?
During the decaffeination process the coffee beans come into direct contact with the solvent, which is then removed through vaporisation. Dichloromethane has a boiling point of 40°C, and therefore it is easy to remove at the end of the process, leaving only insignificant levels of the solvent on the roasted coffee.
Is methylene chloride decaffeination safe?
The U.S. Food and Drug Administration (FDA) has determined that Methylene Chloride decaf is safe for use in coffee decaffeination and FDA regulation allows for up to 10 parts per million (ppm) of residual methylene chloride in decaffeinated coffee.

What is the process of decaffeination?
It is a decaffeination process by which the molecules of caffeine bond to molecules of methylene chloride. It is believed that methylene chloride is not the best possible and healthiest method of decaffeinating, although this process is noted for maintaining more of the original flavor of the tea than other methods.
