SUMMARY
The discussion focuses on methods to extract caffeine from coffee beans and tea leaves, highlighting three primary techniques. One effective method involves using dichloromethane (DCM) and sodium carbonate (NaCO3) for extraction, followed by evaporation to isolate caffeine. The conversation also mentions that while DCM was historically used for decaffeination, it is now avoided due to health risks. An alternative method discussed is the use of superheated steam, commonly known as espresso extraction.
