Dichloromethane is a solvent used to combine and separate caffeine molecules from green coffee seeds. The KVW MC process first uses hot water to extract caffeine and other soluble substances from coffee seeds and then removes the seeds from the water. Dichloromethane is then added to the aqueous solution, which binds to caffeine; because MC is immiscible with water, it is easily separated from the solution with bound caffeine, and coffee seeds are immersed in water again to absorb their soluble compounds. The US Food and Drug Administration has stated that MC is safe to use during decaffeination and is harmless to humans at 10 parts per million or less. Coffee that uses this method to remove caffeine has been shown to contain only a fraction of the safe amount.
