Decaffeinated coffee can be an ideal way to lower caffeine intake while still enjoying its delightful taste. At one time it was believed that most decaf coffee was produced using formaldehyde; now however, researchers believe the vast majority of decaffeinated coffee does not involve formaldehyde processing. Formaldehyde gas may be produced during high temperature roasting of coffee, but not for decaffeinated varieties. Most decaf coffee today is processed using either methylene chloride or ethyl acetate as decaf agents. Methylene chloride and ethyl acetate are volatile chemicals similar to acetone, yet don’t leave a residue on beans when used to decaffeinate coffee beans. Therefore, they provide an easier and safer option when decaf coffee decaf is required and are utilized by both Swiss Water Process and Mountain Water Process methods for decaffeinated coffee production; with only organic decaf coffee approved to use this process 100% chemical free method!
