CoffeeDecaffeinated Coffee Through a process of removing the natural caffeine content of coffee, a decaffeinated option is made available to coffee drinkers. This is a popular option, although the health problems associated with caffeine in coffee are not significant for healthy people when the coffee is taken in moderation. The lack of caffeine removes the stimulant effects of your cup of coffee, and therefore it is not a choice favoured by most coffee drinkers. Arabica beans have a lower caffeine content than Robusta beans. Better quality coffees therefore have a lower stimulant effect than lower quality coffees. Because most instant coffees are made using Robusta beans, you may find you experience a greater stimulant effect from instant coffee than you notice from coffee made directly from the ground beans. The process of decaffeinating coffee most commonly consists of soaking the beans in hot liquid to dissolve the caffeine. This process extracts the flavors from the beans as well. The beans are drained and a second step removes the caffeine from the soaking liquid. This liquid is then returned to soak the beans for long enough to allow them to re-absorb the flavors. The soaking process may be direct or indirect. In the direct method the soaking liquid includes the chemicals that extract the caffeine. The beans are drained and the solvents are then removed and the water returned to soak the beans again and restore the flavors. In the indirect method hot water is used to soak the beans, then the beans are drained and the water treated with chemicals to remove the caffeine. The chemicals are removed and the water is returned to soak the beans again and restore the flavors. Methylene chloride is the lowest cost chemical solution used to absorb the caffeine, and it leaves no residual after roasting. However, it has been mostly supplanted because of the ozone depletion issues linked to this chemical. Ethyl acetate is a naturally occurring chemical that is a common alternative used to absorb the caffeine. Another method uses supercritical carbon dioxide, under high pressure, to absorb the caffeine from the soaking water. A method called the Swiss water process avoids chemicals by removing the caffeine using a carbon filter, but its most unique feature is the re-use of water that has been already saturated with the flavors from coffee beans. This way the beans do not lose their flavor at all during the soaking process, and do not need a second soaking. These processes leave the beans with their coffee flavors intact so “decaf” coffee drinkers can still enjoy the coffee characteristics but without the stimulant effects of its natural caffeine content. Health conscious people concerned about the effects of caffeine in coffee are then able to relax and enjoy their coffee along with everyone else. |
