Topic: Decaffeination


  
  Decaffeinated Coffee Beans
Almost every process for decaffeination consists of soaking the beans in water to dissolve the caffeine, extracting the caffeine with either a solvent or activated carbon, and then re-soaking the coffee beans in the decaffeinated water to reabsorb the flavor compounds that were lost in the initial extraction.
The chemical composition of decaffeinated coffee (or decaf coffee) is altered, and therefore the flavor and aroma are changed.
The sparkling water decaffeination process is similar to the CO method, but instead of removing the caffeine with activated carbon filters, the caffeine is washed from the CO with sparkling water in a secondary tank, which is then recycled to extract more caffeine from the coffee.
