AI Insight
This review examines solid-phase microextraction (SPME) as an environmentally friendly sample preparation technique for analyzing volatile organic compounds in coffee. The authors evaluate various SPME applications in coffee profiling and assess their greenness using the AGREEprep metric, which systematically rates the environmental sustainability of analytical preparation methods. The review demonstrates that SPME offers significant advantages over traditional extraction techniques by reducing solvent consumption, minimizing waste generation, and improving analytical efficiency while maintaining high sensitivity for volatile compound detection.
Why it matters
This work provides guidance for analytical chemists and food scientists seeking sustainable methods for coffee quality control and authentication. By identifying greener alternatives to conventional solvent-based extraction, the research supports the broader movement toward environmentally responsible laboratory practices in food analysis and could be extended to other food matrices requiring volatile compound profiling.
