Q Research General
The first commercially successful decaffeination process was invented by German merchant Ludwig Roselius and co-workers in 1903, after Roselius observed that a consignment of coffee beans accidentally soaked in sea water had lost most of their caffeine content while losing little of their flavour.[4][5] The process was patented in 1906, and involved steaming coffee beans with various acids or bases, then using benzene as a solvent to remove the caffeine.[6][7] Coffee decaffeinated this way was sold as Kaffee HAG after the company name Kaffee Handels-Aktien-Gesellschaft (Coffee Trading Company) in most of Europe, as Café Sanka in France and later as Sanka brand coffee in the United States. Café HAG and Sanka are now worldwide brands of Kraft Foods.
Methods similar to those first developed by Roselius have continued to dominate, and are sometimes known as the direct organic solvent method. However, because of health concerns regarding benzene (which is recognized today as a carcinogen),[8] other solvents, such as dichloromethane or ethyl acetate, are now used.[9] The unroasted (green) beans are first steamed and then rinsed with the solvent which extracts the caffeine, while leaving other constituents largely unaffected. The process is repeated between 8 and 12 times until the caffeine content meets the required standard (97% of caffeine removed according to the US standard, or 99.9% caffeine-free by mass per the EU standard).[3]
