A new molecular ionization technique known as matrix-assisted laser desorption/ionization (MALDI) was first reported by two groups in 1988 1.2. This ionization technique is most often coupled with the simplest form of mass spectrometry (MS), time-of-flight (TOF). The advantages of this ionization technique were quickly recognized and commercially available MALDI-MS instruments started to appear in 1991. Now, after significant improvements in instrumentation MALDI-MS has become a common analytical technique. While MALDI-MS is still relatively unknown by food scientists, it offers significant advantages over other analytical methods for food analysis.
