The process involves using high-pressure carbon dioxide to extract caffeine from coffee beans, resulting in a decaffeinated product that is 97-99% caffeine-free.
How the Carbon Dioxide Decaffeination Process Works
The carbon dioxide decaffeination process is a complex one, involving several stages:
- Bean Selection and Preparation: Green coffee beans are selected and prepared for the decaffeination process. The beans are cleaned and sorted to ensure uniformity and quality.
- Steaming: The green coffee beans are steamed to open up the pores and allow for better caffeine extraction.
- Carbon Dioxide Treatment: The steamed coffee beans are then placed in a pressure vessel where high-pressure carbon dioxide is applied. The carbon dioxide selectively extracts the caffeine from the coffee beans, leaving the other flavor compounds intact.
- Activation: The carbon dioxide is then activated, allowing it to bond with the caffeine molecules and extract them from the coffee beans.
- Removal of Caffeine: The caffeine-laden carbon dioxide is then removed from the pressure vessel, leaving behind decaffeinated coffee beans.
- Drying and Packaging: The decaffeinated coffee beans are then dried and packaged for distribution.
