Explanation:
Detailed explanation-1: -The coffee beans are first immersed in hot water to extract their caffeine and flavorful components. The initial beans are then discarded, and the resulting flavor-rich water (called “green coffee extract”) is passed through a carbon filter that is sized to capture only the large caffeine molecules.
Detailed explanation-2: -Decaffeination is performed prior to roasting. The most common and least costly caffeine extraction methods in the coffee industry basically employ an organic solvent such as dichloromethane or ethyl acetate, associated with the use of water/vapour prior to and after extraction for washing and opening of the pores.
