Abstract
The process described herein improves the decaffeination of both wet and dry green coffee beans with a liquid or supercritical carbon dioxide extractant by dissolving dimethyl sulfoxide in the extractant prior to contact with the beans. Rates of extraction are greatly improved, especially in the preferred mode where the dimethyl sulfoxide is employed at near saturation levels.
