About The Sugar Cane (Ethyl Acetate) Decaf Process The Sugar Cane (Ethyl Acetate) Decaffeination process begins with gently steaming the coffee beans at low pressure to remove their silvery skins. The beans are then moistened with hot water, causing them to swell and soften. This step initiates the hydrolysis of caffeine, which is bound to the chlorogenic acid salts inside the beans. This is known as the preprocessing step. Next, the beans are placed in extractors filled with humidified coffee. Caffeine removal is carried out by thoroughly washing the beans with a recirculating natural solvent, ethyl acetate (EA). This process is repeated several times to ensure the removal of at least 97% of the caffeine content, a step referred to as extraction. After the caffeine extraction, any remaining ethyl acetate is eliminated by passing low-pressure, saturated steam through the coffee beans. This final step ensures that almost all residual traces of ethyl acetate are removed, leaving no more than 5 parts per million (ppm) of EA in the green coffee beans. The beans are then sent to vacuum drying drums to remove the excess moisture added during the humidification process. This step…
