Inventions: sucking the caffeine out of coffee

US-based Decaf Company is ready to licence newly developed polymers that can be used to control or remove caffeine content in all beverages as they are served, according to an article posted 27/07/2006 on
The polymers, known officially as molecularly-imprinted polymers or MIPs, can be attached to either a stirrer or cup. When used in a beverage the MIPs then bind caffeine molecules to them, removing them from the drink itself. DeCaf said a few stirs could cut caffeine by up to 70 per cent.
Most coffee beans are decaffeinated using chemicals that soak up the caffeine molecules, which can also dampen flavour and aroma. According to DeCaf Company, its new polymers could decaffeinate coffee without altering the coffee beans or tea leaves and without the use of chemicals.
