Here is a brief outline of each method and the way that caffeine is extracted (6Trusted Source):
- Solvent-based process: This process uses a combination of methylene chloride, ethyl acetate, and water to create a solvent that extracts the caffeine. As they vanish, neither chemical can be found in coffee.
- Swiss water process: This really is the sole organic way of decaffeinating coffee. It depends on osmosis to extract caffeine and guarantees a 99.9% decaffeinated product.
