Although many enjoy a good cup of coffee, often, some people do not want caffeine in their system. These people opt for decaffeinated coffee. Decaffeinated coffee is coffee that has most of the caffeine removed. Usually, when calculating the weight, the amount of caffeine found naturally in coffee is about 1% for Arabica coffee to 2% in Robusta coffee bean type.
Therefore, when on a packet of coffee, says it is 97% decaffeinated,this means that 97% of 1% or 2% of caffeine was removed. At this point, there are two methods that are used to remove caffeine from coffee.
The first way to remove caffeine from coffee is known as the European process. This is the main method of decaffeinated coffee. It is a chemical process that originated in Europe. In the European process, the beans are first soaked in water and then washed in methylene chloride. This allows caffeine to be absorbed from the beans. The beans are then rinsed from chemicals, dry completely and sent to roast.
The European decaffeinatization process leaves much more flavor than the other method, namely the Swiss water method. Even if the beans are cleaned well and there is virtually no amount of chemicals left on the beans when roasting is complete, some people do not like the fact that their coffee drink has been chemically processed.
