Swiss Water Decaffeination Process

Wonder why we only use the natural swiss water process for decaffeination? Here is some history regarding the chemicals used in the conventional decaffeination process: Toxic solvents were used in early decaffeination efforts, including benzene, chloroform, and trichloroethylene (TCE). Dichloromethane, CH2Cl2, became the solvent of choice in the early 1970's because of its lower toxicity and its ability to selectively dissolve caffeine without carrying off sugars, peptides, a...nd flavor ingredients. However, when evidence suggested that CH2Cl2 might be carcinogenic, its use was sharply curtailed. Ethyl acetate was used as a replacement for dichloromethane during the 80's and early 90's. Although it is moderately toxic, coffee makers touted ethyl acetate as "natural" because it was present in fruit but the ethyl acetate used for decaffeination is synthetic. We don’t want any moderately toxic chemicals in our coffee!!
