Analytical Opportunities and Challenges in Essential Oils Analysis

Abstract:

It is now two decades that comprehensive two-dimensional gas chromate-graphy (GC×GC) has been available. The multidimensional GC and GC×GC provide very high separation power and proved to be useful to assist in screening mass spectrometry data for saffron essential oil, giving better identification. Integrating MDGC with GC×GC for aroma analysis allows Philip’s team to profile the overall sample composition, with MDGC permitting dual olfactometry (sniffing) and MS detection, and odour-active compound identification. The discovery aspect GC×GC-accTOFMS provides a unique ability to ask critical questions about minor and major components in samples like coffee, wine, orange juice, banana liquor, and herb, and the increased secondary metabolite coverage simply gives researchers an expanded pool of compounds upon which to draw conclusions. This talk will start with a brief ‘tutorial’ introduction to Philip’s methods, and feature research conducted by some of his Malaysia students.
