In response to concerns about chemical solvents, the coffee industry sought more natural and environmentally friendly decaffeination methods. This led to the development of the Swiss Water Process, an innovative technique that relies on hot water and activated charcoal filters to extract caffeine from green coffee beans. It does not involve the use of chemical solvents, making it a preferred choice for those seeking a more natural decaffeination process.

Carbon Dioxide (CO2) Method

Another advancement in decaffeination methods came with the use of supercritical carbon dioxide (CO2) to extract caffeine. The CO2 method is highly efficient and environmentally friendly, as it does not involve the use of chemical solvents. It gained popularity among coffee producers and consumers alike.

Triglyceride Process

The more recent introduction of the triglyceride process represents a novel approach to decaffeination. This method combines water, heat, and a food-grade solvent to remove caffeine while aiming to preserve the flavor and aroma of coffee. The process reflects a continued effort to enhance the quality of decaffeinated coffee.

Modern-Day Decaffeinated Coffee

In the 21st century, decaffeinated coffee has become a well-established segment of the coffee industry.
