A Coffee Decaffination Process
a: Carbon dioxide ~
b: a magnet
What: "The beans are soaked in a bath of supercritical carbon dioxide at very high pressure for about 10 hours. The carbon dioxide is like a magnet and attracts all the caffeine molecules. When the pressure is reduced the CO2 evaporates. This process has the advantage of not using any harmful substances and does not chemically affect the proteins or carbohydrates of the bean."
