Rapid Fingerprinting of Volatile Components in Coffee Varieties Using Torion T-9 Portable GC/MS

Introduction

Hundreds of volatile/semivolatile aroma and flavor compounds have been identified in coffee using traditional laboratory based headspace GC/MS systems1. We present a study for rapid fingerprinting of coffee volatile/semi-volatile compounds using solid phase micro-extraction (SPME) coupled to a portable GC/MS system for separation and detection. The on-site analysis of coffee using portable technology can be used for quick quality control check of raw and finished products, comparison of competitor products, analysis of storage conditions or for process development.
